    Description

    FIELD OF THE INVENTION



    [0001] The present disclosure relates to absorbent articles, more particularly, to disposable absorbent articles comprising improved elastomeric laminates configured to perform in various components of the disposable absorbent articles.

    BACKGROUND OF THE INVENTION



    [0002] To don a closed-form pant, the wearer starts by grasping the article at the waist edge, putting their feet into the waist opening, and then stretching and pulling the pant up over their hip to the waist. Adults typically perform this on themselves, as do many toddlers and young children. In other cases, a caregiver may don the pant onto the user. Donning the closed-form pant can be difficult, especially if the relaxed waist opening of the pant is much smaller than the largest body circumference it needs to be pulled over. Conversely, to maintain good fit after donning, the waist region of the pant must deliver sufficient pressure to the waist and hip of the user. To deliver sufficient pressure, the waist region of the pant needs to be stretched while worn on the body, hence the relaxed waist of the pant needs to be smaller than the waist and hip of the user. Consequently, there are conflicting needs for a closed-form pant. A large relaxed waist relative to the body of the user for donning ease, and a small relaxed waist relative to the body of the user for good fit.

    [0003] Closed-form pant products currently in the market which comprise of elastic strands for the waist belt tend to compromise on donning ease in order to deliver sufficient wearing pressure to the body of the wearer. This is due to their Average-Strand-Spacing and Average-Dtex, which result is a relatively low modulus and therefore require more stretch to deliver the necessary pressure. They achieve this greater in-use stretch via greater pre-strain, which results in their relaxed waists being significantly smaller than the body of the user. Once applied, such structures result in higher than desired Pressure-Under-Strand leading to reduced comfort and increased skin marking.

    [0004] A key benefit of present disclosure is that the improved elastomeric laminates deliver sufficient wearing pressure, necessary for good fit, without the amount of pre-strain required in todays currently marketed stranded closed-form pant articles. This results in closed-form pant articles that do not compromise on donning ease. Once applied, such structures result in lower Pressure-Under-Strand leading to increased comfort, improved fit, and little or no skin marking.

    [0005] There has therefore been a long standing unmet consumer need which is to create a product that delivers very low pressure on the skin, adequate force for sustained fit, low modulus, high extensibility. Such an absorbent article would provide improved skin condition, skin marking, ease of application, ease of removal, improved sustained fit, improved gasketing, as well as improved body conformity and wearer comfort.

    [0006] To deliver against all of the unmet consumer needs requires a complete structural redesign of the elastomeric laminates used in the absorbent article. The balance of elastic decitex, elastic strand spacing, number of elastics, and elastic pre-strain required to deliver such a unique blend of properties requires elastic decitex that are very low, well below that of the prior art, disposed at elastic to elastic spacing that are also very low, also well below the prior art, which in turn requires a larger number of elastics well above that known in the prior art, and elastic strains that are also low and well below nearly all of the known prior art.

    [0007] There are several interdependent structural parameters including: strand decitex, strand spacing, modulus, Donning-Ratio, and Pressure-Under-Strand. Balancing these unique properties enable elastomeric laminates of the present disclosure to deliver low pressure on the skin, comfortable fit, and donning ease while delivering a sufficient hoop force of 7 gf/mm providing sustained fit and gasketing of the article.

    [0008] The donning benefit of the present disclosure is enabled by elastomeric laminates comprising a greater number of elastic strands having a greater fineness (e.g., a smaller decitex) and a closer spacing than has been previously disclosed or practiced in disposable absorbent articles. These improved elastomeric laminates can be used as disposable absorbent article (for example, baby and adult taped diapers, baby and adult pants, feminine pads, and feminine liners) components to achieve a variety of benefits in conjunction with and beyond donning, including fit and gasketing at the waist, legs, crotch and sides of the wearer to generally provide the greatest level of extensibility, the most comfortable wearing conditions, improved skin condition (i.e., reduced skin marking), improved leakage protection and a better fit.

    [0009] The benefits disclosed herein are in contrast to traditional elastomeric laminates known today, which typically comprise elastic strands of higher (versus the disclosed elastomeric laminates) decitex and greater (versus the disclosed elastomeric laminates) spacing, which results in higher pressure imparted by each elastic on the skin and larger uncontrolled rugosities in the elastomeric laminate both of which leads to increased skin marking and reduced comfort. Traditional elastomeric laminates typically comprise a plurality of elastics spaced at least 4 mm apart due to manufacturing limitations (in combination with consumer requirements). Regarding film elastomeric laminates, they are significantly more occlusive (i.e., less breathable, no air permeability), resulting in greater hydration of the skin and increased marking associated with the hydrated skin. Also, film elastomeric laminate tends to have a higher modulus versus stranded elastomeric laminates, therefore being more difficult to apply (making it difficult to open for donning), and also requiring more sizes to cover a given fit range of wearers. Regarding extruded strands, similar to many films, they typically comprise thermoplastic materials that experience stress relaxation over time and thus do not maintain the proper forces at the waist and legs to provide proper and sustained fit over the entire wearing time.

    [0010] US 2004/158217 A1 discloses a cloth-like laminate and absorbent garment.

    SUMMARY OF THE INVENTION

    DETAILED DESCRIPTION



    [0023] The present disclosure details improved elastomeric laminates (also referred to as "beamed elastomeric laminates" comprising "beamed elastics") comprising a greater number of elastic strands having a greater fineness (i.e., lower decitex) and a closer spacing than has been previously disclosed or practiced in disposable absorbent articles. These improved elastomeric laminates can be used as disposable absorbent article (for, example, taped diapers, pants, pads, and liners) components for fit and gasketing at the waist, legs, crotch and sides of the wearer to generally provide the greatest level of extensibility, the most comfortable wearing conditions, improved leakage protection and a better fit.

    [0024] The following term explanations may be useful in understanding the present disclosure:

    "Disposable," in reference to absorbent articles, means that the absorbent articles, are generally not intended to be laundered or otherwise restored or reused as absorbent articles (i.e., they are intended to be discarded after a single use and, preferably, to be recycled, composted or otherwise discarded in an environmentally compatible manner). Disposable absorbent articles often comprise adhesive between the layers and/or a plurality of elastics to hold the article together (e.g., ear panels, side panels, and belts are joined to the chassis via adhesive and the layers of the ear panels, side panels, belts, and chassis are joined together using adhesive). Alternatively, heat and/or pressure bonding are used with the adhesive or in place of the adhesive. In such instances portions of the material layers may become partially melted and pressed together such that once cooled they are physically bonded together. Nonwovens (including, for example, polypropylene, polyethylene, etc.) adhesives (including, for example, styrenic block copolymers (e.g., SIS, SBS)), and absorbent gelling material (AGM 51- see FIGS. 7 and 7B) make up more than 50%, more than 75%, and often more than 90% of the disposable absorbent article weight. And, a core comprising the AGM 51 is often held within the chassis in a manner that would encapsulate and contain the AGM 51 under normal conditions. Such disposable absorbent articles typically have an absorbent capacity of greater than about 100 mL of fluid and can have capacities of up to about 500 mL of fluid or more. Stitching (including the use of thread) and/or woven materials are typically not used to make a disposable absorbent article. If stitching or woven materials are used, they make up an extremely small percentage of the disposable absorbent article. Some landing zones of disposable absorbent articles for fasteners can comprise a woven material, but no other part of a disposable absorbent article typically comprises woven materials.

    "Absorbent article" refers to devices, which absorb and contain body exudates and, more specifically, refers to devices, which are placed against or in proximity to the body of the wearer to absorb and contain the various exudates discharged from the body. Exemplary absorbent articles include diapers, training pants, pull-on pant-type diapers (i.e., a diaper having a pre-formed waist opening and leg openings such as illustrated in U.S. Pat. No. 6,120,487), refastenable diapers or pant-type diapers, incontinence briefs and undergarments, diaper holders and liners, feminine hygiene garments such as panty liners, feminine pads, absorbent inserts, and the like.

    "Proximal" and "Distal" refer respectively to the location of an element relatively near to or far from the longitudinal or lateral centerline of a structure (e.g., the proximal edge of a longitudinally extending element is located nearer to the longitudinal axis than the distal edge of the same element is located relative to the same longitudinal axis).

    "Body-facing" and "garment-facing" refer respectively to the relative location of an element or a surface of an element or group of elements. "Body-facing" implies the element or surface is nearer to the wearer during wear than some other element or surface. "Garment-facing" implies the element or surface is more remote from the wearer during wear than some other element or surface (i.e., element or surface is proximate to the wearer's garments that may be worn over the disposable absorbent article).

    "Longitudinal" refers to a direction running substantially perpendicular from a waist edge to an opposing waist edge of the article and generally parallel to the maximum linear dimension of the article. Directions within 45 degrees of the longitudinal direction are considered to be "longitudinal."

    "Lateral" refers to a direction running from a longitudinally extending side edge to an opposing longitudinally extending side edge of the article and generally at a right angle to the longitudinal direction. Directions within 45 degrees of the lateral direction are considered to be "lateral."

    "Disposed" refers to an element being located in a particular place or position.

    "Joined" encompasses configurations whereby an element is directly secured to another element by affixing the element directly to the other element, and configurations whereby an element is indirectly secured to another element by affixing the element to intermediate member(s), which, in turn are affixed to the other element.

    "Water-permeable" and "water-impermeable" refer to the penetrability of materials in the context of the intended usage of disposable absorbent articles. Specifically, the term "water-permeable" refers to a layer or a layered structure having pores, openings, and/or interconnected void spaces that permit liquid water, urine, or synthetic urine to pass through its thickness in the absence of a forcing pressure. Conversely, the term "water-impermeable" refers to a layer or a layered structure through the thickness of which liquid water, urine, or synthetic urine cannot pass in the absence of a forcing pressure (aside from natural forces such as gravity). A layer or a layered structure that is water-impermeable according to this definition may be permeable to water vapor, i.e., may be "vapor-permeable."

    "Elastic," "elastomer," or "elastomeric" refers to materials exhibiting elastic properties, which include any material that upon application of a force to its relaxed, initial length can stretch or elongate to an elongated length more than 10% greater than its initial length and will substantially recover back to about its initial length upon release of the applied force. Elastomeric materials may include elastomeric films, scrims, nonwovens, ribbons, strands and other sheet-like structures.

    "Pre-strain" refers to the strain imposed on an elastic or elastomeric material prior to combining it with another element of the elastomeric laminate or the absorbent article. Pre-strain is determined by the following equation Pre-strain = ((extended length of the elastic-relaxed length of the elastic)/relaxed length of the elastic)100.

    "Decitex" also known as "Dtex" is a measurement used in the textile industry used for measuring yarns or filaments. 1 Decitex = 1 gram per 10,000 meters. In other words, if 10,000 linear meters of a yarn or filament weights 500 grams that yarn or filament would have a decitex of 500.

    "Substrate" is used herein to describe a material which is primarily two-dimensional (i.e. in an XY plane) and whose thickness (in a Z direction) is relatively small (i.e. 1/10 or less) in comparison to its length (in an X direction) and width (in a Y direction). Non-limiting examples of substrates include a web, layer or layers of fibrous materials, nonwovens, films and foils such as polymeric films or metallic foils. These materials may be used alone or may comprise two or more layers laminated together. As such, a web is a substrate.

    "Nonwoven" refers herein to a material made from continuous (long) filaments (fibers) and/or discontinuous (short) filaments (fibers) by processes such as spunbonding, meltblowing, carding, and the like. Nonwovens do not have a woven or knitted filament pattern.

    "Machine direction" (MD) is used herein to refer to the direction of material flow through a process. In addition, relative placement and movement of material can be described as flowing in the machine direction through a process from upstream in the process to downstream in the process.

    "Cross direction" (CD) is used herein to refer to a direction that is generally perpendicular to the machine direction.

    "Taped diaper" (also referred to as "open diaper") refers to disposable absorbent articles having an initial front waist region and an initial back waist region that are not fastened, pre-fastened, or connected to each other as packaged, prior to being applied to the wearer. A taped diaper may be folded about the lateral centerline with the interior of one waist region in surface to surface contact with the interior of the opposing waist region without fastening or joining the waist regions together. Example taped diapers are disclosed in various suitable configurations U.S. Patent Nos. 5,167,897, 5,360,420, 5,599,335, 5,643,588, 5,674,216, 5,702,551, 5,968,025, 6,107,537, 6,118,041, 6,153,209, 6,410,129, 6,426,444, 6,586,652, 6,627,787, 6,617,016, 6,825,393, and 6,861,571; and U.S. Patent Publication Nos. 2013/0072887 A1; 2013/0211356 A1; and 2013/0306226 A1.

    "Pant" (also referred to as "training pant", "pre-closed diaper", "diaper pant", "pant diaper", and "pull-on diaper") refers herein to disposable absorbent articles having a continuous perimeter waist opening and continuous perimeter leg openings designed for infant or adult wearers. A pant can be configured with a continuous or closed waist opening and at least one continuous, closed, leg opening prior to the article being applied to the wearer. A pant can be pre-formed or pre-fastened by various techniques including, but not limited to, joining together portions of the article using any refastenable and/or permanent closure member (e.g., seams, heat bonds, pressure welds, adhesives, cohesive bonds, mechanical fasteners, etc.). A pant can be pre-formed anywhere along the circumference of the article in the waist region (e.g., side fastened or seamed, front waist fastened or seamed, rear waist fastened or seamed). Example diaper pants in various configurations are disclosed in U.S. Patent Nos. 4,940,464; 5,092,861; 5,246,433; 5,569,234; 5,897,545; 5,957,908; 6,120,487; 6,120,489; 7,569,039 and U.S. Patent Publication Nos. 2003/0233082 A1; 2005/0107764 A1, 2012/0061016 A1, 2012/0061015 A1; 2013/0255861 A1; 2013/0255862 A1; 2013/0255863 A1; 2013/0255864 A1; and 2013/0255865 A1.

    "Closed-form" means opposing waist regions are joined, as packaged, either permanently or refastenably to form a continuous waist opening and leg openings.

    "Open-form" means opposing waist regions are not initially joined to form a continuous waist opening and leg openings but comprise a closure means such as a fastening system to join the waist regions to form the waist and leg openings before or during application to a wearer of the article.



    [0025] The term "channel," as used herein, is a region or zone in an absorbent material layer that has a substantially lower basis weight (e.g., less than 50%, less than 70%, less than 90%) than the surrounding material in the material layer. The channel may be a region in a material layer that is substantially absorbent material-free (e.g., 90% absorbent material-free, 95% absorbent material-free, or 99% absorbent material-free, or completely absorbent material-free). A channel may extend through one or more absorbent material layers. The channel generally has a lower bending modulus than the surrounding regions of the absorbent material layer, enabling the material layer to bend more easily and/or rapidly distribute more bodily exudates within the channel than in the surrounding areas of the absorbent material layer. Thus, a channel is not merely an indentation in the material layer that does not create a reduced basis weight in the material layer in the area of the channel.

    DONNING-RATIO



    [0026] Donning ease can be assessed by a Donning-Ratio, as illustrated in FIG. 1. A Donning-Ratio of less than 1 indicates that the consumer's hip width is less than the Relaxed-Product-Waist-Width. Donning-Ratio's less than 1 are not desirable since the products contracted width is greater than the wearer's hip width, and thus, would deliver insufficient pressure against the body to sustain fit. A Donning-Ratio of greater than 1 indicates that the consumer's hip width is greater than the Relaxed-Product-Waist-Width. Donning-Ratio's that approach without falling below 1, while also delivering sufficient pressure for fit, are desirable for ease of donning, wearer comfort, pressure on skin, etc. Donning-Ratio's greater than 2 or even 3 are not within the scope of the present disclosure, but require a unique balance of elastic decitex, elastic strand spacing, number of elastics and elastic pre-strain to deliver such a unique blend of properties. The unique set of properties requires elastic decitex that are very low, well below that of the prior art, disposed at elastic to elastic spacing that are also very low, also well below the prior art, which in turn requires a larger number of elastics well above that known in the prior art, and elastic strains that are also low and well below nearly all of the known prior art. The specific set of criteria required to deliver against the aforementioned unmet consumer needs with a single product not only requires unique elastomeric laminate structures but it requires a new process, beamed elastic (a plurality of elastics formed on and delivered from a beam or spool), for delivery of such a large number of low decitex elastics, at low pre-strain and low spacing in order to achieve the right balance of elastomeric laminate properties. These unique properties enable a higher Donning-Ratio while delivering low force on the skin, Pressure-Under-Strand, ease of application, comfort, fit, etc. Such an approach to the best of our knowledge has never before been disclosed or attempted in the field of absorbent articles; hygiene articles, taped diapers, diaper pants, adult incontinence articles, menstrual products, etc.

    [0027] The Donning-Ratio is calculated as:



    [0028] The Donning-Ratio is unitless. Both the Target-Hip and Relaxed-Product-Waist-Width are in mm.

    [0029] FIG. 17 shows that for over 90% of consumers, their hip circumference is greater than their waist circumference. Therefore, when donning a closed-form pant, pulling it up over the hip represents the largest body region the pant needs to stretch over.

    [0030] Typically packages 610 of absorbent articles 100 (see FIG. 26) are labeled with a recommended wearer weight range (typically for babies, infants, and toddlers) and/or by waist circumference (typically for adult absorbent article products) that the packaged article is intended to fit. As a result, the weight and/or the waist circumference information is most often placed on the package 610 as part of the indicia 1000 to identify the appropriate size of the article needed by the consumer. For products recommended by weight range, an Average Targeted Weight is the average of the minimum and maximum recommended weights.

    [0031] For many adult incontinence products, only a waist recommendation is provided. For these products, an Average Targeted Weight can still be determined by calculating the Average Weight at the minimum and maximum recommended waists. FIG. 19 shows this relationship and calculation.



    [0032] Once the Average Targeted Weight for a product is determined, its corresponding Target-Hip is determined as shown on FIG. 18.


    ABSORBENT ARTICLES OF THE PRESENT DISCLOSURE



    [0033] Products comprising elastomeric laminates of the present disclosure may comprise absorbent articles 100 of differing structure and/or form that are generally designed and configured to manage bodily exudates such as urine, menses, and/or feces, such as disposable taped and pants, including baby and adult disposable absorbent articles.

    [0034] As shown in the figures, the absorbent articles 100 of the present disclosure comprise a chassis 200 comprising a topsheet 124, a backsheet 125, and an absorbent core 128 disposed at least partially between the topsheet 124 and the backsheet 125. The chassis 200 may further comprise an inner leg cuff 150 and an outer leg cuff 140 (the cuffs generally referred to as 52).

    [0035] One end portion of an absorbent article 100 is configured as a front waist region 36 and the longitudinally opposing end portion is configured as a back waist region 38. An intermediate portion of the absorbent article 100 extending longitudinally between the front waist region 36 and the back waist region 38 is configured as a crotch region 37. The length of each of the front waist region 36, the back waist region 38 and the crotch region 37 may be about 1/3 of the length of the absorbent article 100, for example (see, for example, FIGS. 9 and 10). Alternatively, the length of each of the front waist region 36, the back waist region 38, and the crotch region 37 may have other dimensions (e.g., defined by the belt or ear panel or side panel dimensions - see, for example, FIGS. 3B, 4, and 7). The absorbent article 100 may have a laterally extending front waist end edge 136 in the front waist region 36 and a longitudinally opposing and laterally extending back waist end edge 138 in the back waist region 38.

    [0036] The chassis 200 of the absorbent article 100 may comprise a first longitudinally extending side edge 237a and a laterally opposing and second longitudinally extending side edge 237b. Both of the side edges 237 may extend longitudinally between the front waist end edge 136 and the back waist end edge 138. The chassis 200 may form a portion of the laterally extending front waist end edge 136 in the front waist region 36 and a portion of the longitudinally opposing and laterally extending back waist end edge 138 in the back waist region 38. Furthermore, the chassis 200 may comprise a chassis interior surface 202 (forming at least a portion of the wearer-facing surface 4), a chassis exterior surface 204 (forming at least a portion of the garment-facing surface 2), a longitudinal axis 42, and a lateral axis 44. The longitudinal axis 42 may extend through a midpoint of the front waist end edge 136 and through a midpoint of the back waist end edge 138, while the lateral axis 44 may extend through a midpoint of the first side edge 237a and through a midpoint of the second side edge 237b.

    [0037] Referring to FIG. 7, often true for belted absorbent articles, the chassis 200 may have a length measured along the longitudinal axis 42 that is less than the length of the absorbent article 100. Both of the side edges 237 of the chassis 200 may not extend longitudinally to one or both of the front waist end edge 136 and the back waist end edge 138. The chassis 200 may not form a portion of one or both of the laterally extending front waist end edge 136 in the front waist region 36 and the longitudinally opposing and laterally extending back waist end edge 138 in the back waist region 38.

    [0038] Referring to FIG. 7B, the chassis 200 may comprise a plurality of elastics 316 are oriented parallel with the longitudinal axis 42 between the backsheet nonwoven 127 and backsheet film 126. FIG. 7C shows an alternate embodiment than FIG. 7B, where the chassis 200 has a plurality of elastics 316 oriented parallel with the longitudinal axis 42 between the core wrap 74 and the backsheet 125. Still further, FIG. 7D shows another alternative embodiment where the chassis 200 comprises a plurality of elastics 316 oriented parallel with the lateral axis 44 between the backsheet film 126 and the backsheet nonwoven 127. FIG. 7B also shows a plurality of elastics 316 oriented parallel with the longitudinal axis 42 between a first topsheet layer 124a and a second topsheet layer 124b, whereas FIG. 7C shows an alternate embodiment where the plurality of elastics 316 are between the topsheet 124 and the core wrap 74. Still further, FIG. 7D shows a plurality of elastics 316 oriented parallel with the lateral axis 44 between the topsheet 124 and the core wrap 74.

    [0039] Still regarding an elasticized chassis 200, FIGS. 12A, B, and C show an elasticized chassis 200, where a plurality of elastics 316 are disposed between layers of the wings 120. FIG. 12 shows a plurality of elastics 316 oriented at about 45 degrees relative to the longitudinal axis 42 and the lateral axis 44. FIG. 12A is an alternate embodiment of FIG. 12, showing the plurality of elastics 316 oriented parallel with the longitudinal axis 42. FIG. 12B shows two layers of elastics 316 in the wings 120, both oriented parallel with the longitudinal axis 42, the lower layer of elastics 316 being spaced with gaps between groupings, and separated by a nonwoven wing layer 121. FIG. 12C is an alternate embodiment of FIG. 12B, where there is only one layer of elastics and no nonwoven wing layer 121. FIG. 12C also shows a plurality of elastics 316 oriented parallel with the longitudinal axis 42between the topsheet 124 and secondary topsheet 124' (which may alternatively be oriented parallel with the lateral axis 44 - not shown), and a plurality of elastics 316 oriented parallel with the longitudinal axis 42 between the backsheet film 126 and the backsheet nonwoven 127 (which may alternatively be oriented parallel with the lateral axis 44 - not shown).

    [0040] A portion or the entirety of the absorbent article 100 may be made to be laterally elastically extensible. The extensibility of the absorbent article 100 may be desirable in order to allow the absorbent article 100 to conform to a body of a wearer during movement by the wearer. The extensibility may also be desirable, for example, in order to allow the caregiver to extend the front waist region 36, the back waist region 38, the crotch region 37, and/or the chassis 200 to provide additional body coverage for wearers of differing size, i.e., to tailor the fit of the absorbent article 100 to the individual wearer and to aide in ease of application. Such extension may provide the absorbent article 100 with a generally hourglass shape, so long as the crotch region 37 is extended to a relatively lesser degree than the waist regions 36 and/or 38. This extension may also impart a tailored appearance to the absorbent article 100 during use.

    [0041] The chassis 200 may be substantially rectangular and may have discrete side panels 330 (FIG. 3B), extensible ear panels 530 (FIG. 9) and/or non-extensible ear panels 540 (FIG. 9) joined to the chassis 200 at or adjacent the chassis side edges 237 in one or both of the front waist region 36 and back waist region 38. Portions of one or more of the chassis side edges 237, the chassis front end edge 236 and the chassis back end edge 238 may be arcuate or curved either convexly or concavely as shown in FIGS. 11, 11A, and 12. The chassis 200 may comprise integral side panels 330 (see FIG. 4), integral extensible ear panels (see FIG. 10), integral belts 430 (see FIG. 8) or integral non-extensible ear panels 540 formed by one or more of the outer cover nonwoven, backsheet film, outer leg cuff material, topsheet or core wrap 74 disposed in one or both of the front and back waist regions (FIG. 9). Alternatively, the chassis 200 may comprise discrete side panels 330 (see FIG. 3B), discrete extensible ear panels 530 (see FIGS. 9, 9A, and 10), or discrete belts 430 (FIGS. 5-7D). The chassis may be shaped or non-rectangular, in one waist region and substantially rectangular in the opposing waist region. Alternatively, the chassis may be substantially rectangular in one or both of the waist regions and non-rectangular in the crotch region.

    [0042] Absorbent articles of the present disclosure may comprise a plurality of laterally extending elastics wherein the elastics are present in a first waist region, the crotch region and in the opposing second waist region.

    CLOSED-FORM PANT ARTICLE



    [0043] Closed-form, pant-style, absorbent articles are generally disclosed in FIGS. 3-8, and are designed to be packaged in closed-form having a waist opening 190 and two leg openings 192, and designed to be donned onto the wearer like a pair of durable underwear. The pant may comprise discrete elastomeric side panels 330 (FIG. 3B) and/or discrete belts 430 (FIG. 7) in one or both of the front waist region 36 and back waist region 38. Alternatively, the side panels 330 and/or belts 430 may be formed integrally with other elements of the article such as the chassis 200 (FIGS. 4 and 8).

    [0044] When the absorbent article comprises front and back belts 430, the sides of front and back belts 430 may be joined permanently or refastenably to each other and the front and back side panels on one side of the article may be joined permanently or refastenably to each other to create a waist opening 190 and a pair of leg openings 192 (FIGS. 5, 5A, and 6). The belts 430 provide an elastically extensible feature that provides a more comfortable and contouring fit by initially conformably fitting the article 100 to the wearer and sustaining this fit throughout the time of wear well past when the pant has been loaded with exudates since the elastomeric side panels allow the sides of the pant to expand and contract. Further, the elastomeric belts 430 provide ease of application and develop and maintain wearing forces and tensions to maintain the article 100 on the wearer and enhance the fit, especially when beamed elastomeric laminates are used to form the belts 430. The elastomeric side panels enable ease of application allowing the pant to be pulled conformably over the hips of the wearer and positioned at the waist where the belts 430 conform to the body and provide tension sufficient to maintain the articles position on the wearer. The tension created by the belts 430 is transmitted from the elastic belts 430 along the waist opening 190 and along at least a portion of the leg opening 192. Typically, particularly regarding discrete side panels 330, the chassis 200 is disposed between the side panels 330 and extends to form a portion of the waist edge 136 and/or 138 of the pant comprising side panels 330. In other words, a portion of the waist edge 136 and/or 138 in one or both of the front waist region 36 and back waist region 38 may be formed in part by the side panels 330 and in part by the chassis 200.

    [0045] The pant comprising side panels 330 may also comprise a pair of laterally opposing refastenable seams 174 as illustrated in FIGS. 3 and 3A. The refastenable side seam 174 may be formed by refastenably joining an interior surface of a portion of the article, e.g. a side panel 330, to an exterior surface of another portion of the article 100, e.g., a longitudinally opposing side panel 330 or the chassis 200 to form the refastenable side seam 174. FIG. 3A illustrates a front side panel 330f comprising a fastener 175 comprising hooks facing away from a wearer (the fastener 175 disposed on an exterior surface of the front side panel 330f) that refastenably attaches to a mating fastener 178 (loops or a suitable nonwoven in FIG. 3A), the mating fastener 178 being disposed on an interior surface of the back side panel 330b. Observe that that FIG. 3A is an alternative embodiment of FIGS. 3 and 3B as the pant of FIGS. 3 and 3B do not comprise a mating fastener 178 - rather, the fastener 175 in FIGS. 3 and 3B refastenably join directly to the back side panels 330.

    [0046] The pant comprising belts 430 may also comprise a first permanent side seam 172 and a laterally opposing second permanent side seam 172 as illustrated, for example, in FIGS. 5, 5A, and 6. The permanent side seam 172 may be formed by joining an interior surface of a portion of the article 100, e.g. a belt 430, to an exterior surface of another portion of the article 100, e.g. a longitudinally opposing belt 430 or the chassis 200 to form the permanent side seam 172. Alternatively, the permanent side seam 172 may be formed by joining an interior surface of a portion of the article 100, e.g. a belt 430, to an interior surface of another portion of the article 100, e.g. a longitudinally opposing belt 430 to form the permanent side seam 172. Any pants comprising side panels 330 configurations described above may comprise a waistband 122 wherein at least a portion of the waistband 122 (as illustrated in FIG. 3B) is disposed at or immediately adjacent the waist edge 136 and/or 138 and overlaps a portion of the center chassis 200. The waistband 122 may extend laterally to overlap portions of the inner leg cuffs 150 and/or portions of the elastomeric side panels 330. The waistband 122 may be disposed on the interior surface 202 of the chassis 200 or alternatively between the topsheet 124 and the backsheet 125.

    [0047] Particularly regarding belts 430, as illustrated in FIG. 7E, the inner belt layer 432 and/or the outer belt layer 434 of the first and second elastomeric belts 430 may be formed by a common belt layer as shown in FIG. 7E. When the first and second elastomeric belts 430 have a common belt layer, the common belt layer may extend from a first waist edge in a first waist region to a longitudinally opposing second waist edge in a second waist region, i.e. front waist edge 136 to back waist edge 138.

    [0048] Also particularly regarding belted pants 400, as illustrated in FIGS. 7 and 7A, the belt pant 400 may have a first elastomeric belt 430 disposed in a first waist region having a first longitudinal length and a second elastomeric belt 430 disposed in a second waist region having a second longitudinal length wherein the longitudinal length of the first belt is greater than the longitudinal length of the second belt along the side edge of the belt at or adjacent the side seam. This length difference helps provide buttock coverage in the back of the pant providing a more underwear-like appearance. And, while this advantage is disclosed for belted pants 400, there is also an advantage in having longitudinally longer side panels 330 in the back waist region 38.

    OPEN-FORM TAPED ARTICLE



    [0049] Open-form, taped-style, absorbent articles are generally disclosed in FIGS. 9-10. The taped diaper 500, open-form article, as illustrated in FIGS. 9 and 10 may comprise elastomeric ear panels 530 in one or both of the front waist region 36 and back waist region 38. The elastomeric ear panels 530 may be unitary structurally with other elements of the article 100 or as a separate element joined to another element of the article 100. The elastomeric ear panels 530 provide an elastically extensible feature that provides a more comfortable and contouring fit by initially conformably fitting the article 100 to the wearer and sustaining this fit throughout the time of wear well past when the taped diaper 500 has been loaded with exudates since the elastomeric ear panels 530 allows the diaper to expand and contract to fit the wearer. Further, the elastomeric ear panels 530 develop and maintain wearing forces (tensions) and enhance the tensions developed and maintained by the fastening system 179 (including the fasteners 175 (e.g., hooks) that may be releasably engaged with a mating fasteners 178 (e.g., loops)), to maintain the article 100 on the wearer and enhance the fit. The elastomeric ear panels 530 especially assist in maintaining the primary line of tension formed by the fastening system 179 allowing the diaper to conformably fit over the hips of the wearer where there is dynamic motion, and initially pre-tensioning the waist opening 190 and leg opening 192 since the diaperer typically stretches the elastomeric ear panels 530 when applying the taped diaper 500 on the wearer so that when the elastomeric ear panels 530 contract, tension is transmitted from the elastomeric ear panels 530 along the waist opening 190 and along at least a portion of the leg opening 192. While the open-form article of the present disclosure may have the elastomeric ear panels 530 disposed in the back waist region 38, alternatively, the taped diaper 500 may be provided with elastomeric ear panels 530 disposed in the front waist region 36 or in both the front waist region 36 and the back waist region 38. The open-form article may also have elastomeric ear panels 530 disposed in a first waist region and elastomeric ear panels 530 or non-elastomeric ear panels 540 disposed in a second waist region.

    [0050] In an alternative embodiment the open-form, taped-style, absorbent articles may comprise an elastomeric belt 430 disposed in one of the waist regions. The elastomeric belt 430 may be joined and/or positioned in a particular place or position and may be unitary structurally with other elements of the article 100 or as a separate element joined to another element of the article 100. A belted taped diaper the elastomeric belt 430 may be disposed in the back waist region 38. The elastomeric belt 430 may have fasteners disposed at or adjacent the laterally opposing ends of the belt. Fasteners 175 may be disposed on the interior surface of the belt 430 to engage with a discrete mating fastening component 178 or with the exterior surface 204 of the article (like the backsheet nonwoven 127) to fasten the article on the wearer.

    OUTER COVER MATERIAL



    [0051] The backsheet 125 may comprise a backsheet film 126 and backsheet nonwoven 127. The backsheet nonwoven 127 may also be referred to as the outer cover material. The outer cover material forms at least a portion of the garment-facing surface of the absorbent article 100 and effectively "covers" the backsheet film 126 so that the film is not present on the garment-facing surface. The outer cover material may comprise a bond pattern, apertures, and/or three-dimensional features.

    ABSORBENT CORE



    [0052] As used herein, the term "absorbent core" 128 refers to the component of the absorbent article 100 having the most absorbent capacity and that comprises an absorbent material. Referring to FIGS. 7, 7B, and 7C, in some instances, absorbent material (e.g., 51 and 53) may be positioned within a core bag or a core wrap 74. The absorbent material may be profiled or not profiled, depending on the specific absorbent article. The absorbent core 128 may comprise, consist essentially of, or consist of, a core wrap, absorbent material, and glue enclosed within the core wrap. The absorbent material may comprise superabsorbent polymers, a mixture of superabsorbent polymers and air felt, only air felt, and/or a foam. In some instances, the absorbent material may comprise at least 80%, at least 85%, at least 90%, at least 95%, at least 99%, or up to 100% superabsorbent polymers, by weight of the absorbent material. In such instances, the absorbent material may free of air felt, or at least mostly free of air felt - in such cases the AGM 51 may be held in place by an adhesive 54, such as a thermoplastic adhesive. And, for swim diapers, the article may be free of superabsorbent polymers. The absorbent core periphery, which may be the periphery of the core wrap, may define any suitable shape, such as rectangular, "T," "Y," "hourglass," or "dog-bone" shaped, for example. An absorbent core periphery having a generally "dog bone" or "hour-glass" shape may taper along its width towards the crotch region 37 of the absorbent article 100.

    [0053] Referring to FIGS. 7, 7B, and 7C, the absorbent core 128 may have areas having little or no absorbent material, where a wearer-facing surface of the core bag 74 may be joined to a garment-facing surface of the core bag 74. These areas having little or no absorbent material may be referred to as "channels" 129. These channels can embody any suitable shapes and any suitable number of channels may be provided. In other instances, the absorbent core may be embossed to create the impression of channels. The absorbent core in FIGS. 7, 7B, and 7C is merely an example absorbent core. Many other absorbent cores with or without channels are also within the scope of the present disclosure.

    [0054] As used herein, a loaded absorbent core is one holding (or capable of holding) a load of at least 50, 100, or 200 milliliters (mls) for diapers, pants, and adult incontinence articles. The disposable absorbent articles of the present disclosure comprising an absorbent core are designed to fit the wearer with an empty absorbent core (i.e., one that is not loaded), as well as being capable of fitting the wear for an appreciable time (2 or more hours) even when the core is loaded.

    ACQUISITION MATERIALS



    [0055] One or more acquisition materials (e.g., 130) may be present at least partially intermediate the topsheet 124 and the absorbent core 128. The acquisition materials are typically hydrophilic materials that provide significant wicking of bodily exudates. These materials may dewater the topsheet 124 and quickly move bodily exudates into the absorbent core 128. The acquisition materials 130 may comprise one or more nonwoven materials, foams, cellulosic materials, crosslinked cellulosic materials, air laid cellulosic nonwoven materials, spunlace materials, or combinations thereof, for example. In some instances, portions of the acquisition materials may extend through portions of the topsheet 124, portions of the topsheet 124 may extend through portions of the acquisition materials, and/or the topsheet 124 may be nested with the acquisition materials. Typically, an acquisition material or layer may have a width and length that are smaller than the width and length of the topsheet 124. The acquisition material may be a secondary topsheet in the feminine pad context. The acquisition material may have one or more channels as described in the absorbent core 128 section (including the embossed version). The channels in the acquisition material may align or not align with channels in the absorbent core 128. In an example, a first acquisition material may comprise a nonwoven material and as second acquisition material may comprise a cross-linked cellulosic material.

    LANDING ZONE



    [0056] Referring to FIGS. 9A, the absorbent article 100 may have a landing zone area 45 that is formed in a portion of the garment-facing surface 2 of the outer cover material. The landing zone area 45 may be in the back waist region 38 if the absorbent article 100 fastens from front to back or may be in the front waist region 36 if the absorbent article 100 fastens back to front. In some instances, the landing zone 45 may be or may comprise one or more discrete nonwoven materials that are attached to a portion of the outer cover material in the front waist region 36 or the back waist region 38 depending upon whether the absorbent article fastens in the front or the back. In essence, the landing zone 45 is configured to receive the fasteners 175 and may comprise, for example, a plurality of loops configured to be engaged with, a plurality of hooks on the fasteners 175, or vice versa.

    WETNESS INDICATOR/GRAPHICS



    [0057] The absorbent articles 100 of the present disclosure may comprise graphics (e.g., a chassis graphic 299, a side panel graphic 399, a belt graphic 499, or an ear panel graphic 599) and/or wetness indicators 80 that are visible from the garment-facing surface 2. The graphics may be printed on the landing zone 45, the backsheet 125, topsheet 124, belts 430, side panels 330, ear panels 530 and/or at other locations. The wetness indicators are typically applied to the absorbent core facing side of the backsheet film 126, so that they can be contacted by bodily exudates within the absorbent core 128. In some instances, the wetness indicators may form portions of the graphics e.g., 299. For example, a wetness indicator may appear or disappear and create/remove a character within some graphics. In other instances, the wetness indicators 80 may coordinate (e.g., same design, same pattern, same color) or not coordinate with the graphics. Alternatively, graphics and/or wetness indicators 80 may be disposed on, and/or visible from, the wearer-facing surface 204.

    [0058] One or more of the side/ear panels 330, 530 may comprise a graphic disposed thereon. One or more of the elastomeric side/ear panels 330, 530 comprise a graphic (e.g., 399, 599) substantially aligned to a chassis graphic 299 to form a composite graphic element. Further, the front and back belts 430f and 430b may comprise graphics. The graphics may extend substantially around the entire circumference of the absorbent article 100 and may be disposed across side seams 172 and/or across proximal front and back belt edges 15 (see FIG. 5); or, alternatively, adjacent to the seams in the manner described in U.S. Pat. No. 9,498, 389 to create a more underwear-like article. The graphics may also be discontinuous.

    TOPSHEETS



    [0059] The absorbent articles 100 of the present disclosure may comprise a topsheet 124. The topsheet 124 is the part of the absorbent article 100 that is in contact with the wearer's skin. The topsheet 124 may be joined to portions of the backsheet 125, the absorbent core 128, the leg cuffs 52, and/or any other layers as is known to those of ordinary skill in the art. The topsheet 124 may be compliant, soft-feeling, and non-irritating to the wearer's skin. Further, at least a portion of, or all of, the topsheet may be liquid permeable, permitting liquid bodily exudates to readily penetrate through its thickness. A suitable topsheet may be manufactured from a wide range of materials, such as porous foams, reticulated foams, apertured plastic films, woven materials, nonwoven materials, woven or nonwoven materials of natural fibers (e.g., wood or cotton fibers), synthetic fibers or filaments (e.g., polyester or polypropylene or bicomponent PE/PP fibers or mixtures thereof), or a combination of natural and synthetic fibers. The topsheet may have one or more layers. The topsheet may be apertured, may have any suitable three-dimensional features, and/or may have a plurality of embossments (e.g., a bond pattern). The topsheet may be apertured by overbonding a material and then rupturing the overbonds through ring rolling, such as disclosed in U.S. Patent No. 5,628,097, to Benson et al., issued on May 13, 1997 and disclosed in U.S. Pat. Appl. Publication No. US 2016/0136014 to Arora et al. Any portion of the topsheet may be coated with a skin care composition, an antibacterial agent, a surfactant, and/or other beneficial agents. The topsheet may be hydrophilic or hydrophobic or may have hydrophilic and/or hydrophobic portions or layers. If the topsheet is hydrophobic, typically apertures will be present so that bodily exudates may pass through the topsheet.

    BACKSHEETS



    [0060] The absorbent article 100 of the present disclosure may comprise a backsheet 125. The backsheet 125 is generally that portion of the absorbent article 100 positioned proximate to the garment-facing surface of the absorbent core 128. The backsheet 125 may be joined to portions of the topsheet 124, the backsheet nonwoven 127, the absorbent core 128, and/or any other layers of the absorbent article by any attachment methods known to those of skill in the art. The backsheet film 126 prevents, or at least inhibits, the bodily exudates absorbed and contained in the absorbent core 128 from soiling articles such as bedsheets, undergarments, and/or clothing. The backsheet is typically liquid impermeable, or at least substantially liquid impermeable. The backsheet may, for example, be or comprise a thin plastic film, such as a thermoplastic film having a thickness of about 0.012 mm to about 0.051 mm. Other suitable backsheet materials may include breathable materials which permit vapors to escape from the absorbent article, while still preventing, or at least inhibiting, bodily exudates from passing through the backsheet.

    LEG CUFFS



    [0061] The absorbent articles 100 of the present disclosure may comprise leg cuffs 52, which include inner leg cuffs 150 and outer leg cuffs 140. The inner leg cuffs 150 may be positioned laterally inboard of outer leg cuffs 140. Each of the leg cuffs 52 may be formed by a piece of material which is bonded to the absorbent article 100 so it can extend upwards from a wearer-facing surface of the absorbent article 100 and provide improved containment of body exudates approximately at the junction of the torso and legs of the wearer. The inner leg cuffs 150 are delimited by an edge joined directly or indirectly to (or formed by) the topsheet and/or the backsheet and a free terminal edge, which is intended to contact and form a seal with the wearer's skin. The inner leg cuffs 150 may extend longitudinally at least partially (or fully) between the front end edge 136 and the back end edge 138 of the absorbent article 100 on opposite sides of the chassis and may be at least present in the crotch region 37. The inner leg cuffs 150 may each comprise one or more elastics 316 (e.g., elastic strands or strips) near or at the free terminal edge. These elastics 316 cause the inner leg cuffs 150 to help form a seal around the legs and torso of a wearer. The outer leg cuffs 140 extend at least partially between the front end edge 136 and the back end edge 138. The outer leg cuffs 140 essentially cause portions of the absorbent article 100 proximate to the chassis side edges 237a and 237b to help form a seal around the legs of the wearer. The outer leg cuffs 140 may extend at least within the crotch region 37.

    WAISTBANDS/WAISTCAPS



    [0062] The absorbent articles 100 of the present disclosure may comprise one or more elastic waistbands 122. The elastic waistbands 122 may be positioned on the garment-facing surface or the wearer-facing surface, or may be formed therebetween. As an example, a first elastic waistband 122 may be present in the front waist region 36 near the front waist edge 136 and a second elastic waistband 122 may be present in the back waist region 38 near the back waist edge 138. The elastic waistbands 122 may aid in sealing the absorbent article 100 around a waist of a wearer and at least inhibiting bodily exudates from escaping the absorbent article 100 through the waist opening circumference. In some instances, an elastic waistband may fully surround the waist opening 190 of the absorbent article 100. A waist cap 123 may be formed by an extension of the waistband 122 and may remain unattached to the underlying structure in the central portion of the waist cap 123 to allow bodily exudates that flow along the topsheet 124 to be trapped between the topsheet 124 and the underside of the waist cap 123. In other words, the waist cap 123 may be joined to the underlying structure, e.g., center chassis 200 of the absorbent article 100 along the longitudinally distal edge of the waist cap 123 and/or along the laterally opposing side edges of the waist cap 123.

    BELTS



    [0063] Beyond what was disclosed about belts in the OPEN-FORM TAPED ARTICLE and CLOSED-FORM PANT ARTICLE Sections above, the front and back belts 430f and 430b may comprise front and back inner belt layers 432 and front and back outer belt layers 434 having an elastomeric material (e.g., a plurality of elastics 316 or a film (which may be apertured)) disposed at least partially therebetween. The plurality of elastics 316 or the film may be relaxed (including being cut) to reduce elastic strain over the absorbent core 128 or, may alternatively, run continuously across the absorbent core 128. The plurality of elastics 316 may have uniform or variable spacing therebetween in any portion of the belts. The plurality of elastics 316 may also be pre-strained the same amount or different amounts. The front and/or back belts 430f and 430b may have one or more elastics free zones where the chassis 200 overlaps the belts 430f and 430b. In other instances, at least some of the plurality of elastics 316 may extend continuously across the chassis 200.

    [0064] The front and back inner belt layers 432 and the front and back outer belt layers 434 may be joined using adhesives, heat bonds, pressure bonds, ultrasonic, or thermoplastic bonds. Various suitable belt layer configurations can be found in U.S. Pat. Appl. Pub. No. 2013/0211363.

    [0065] Front and back belt end edges 438f and 438b may extend longitudinally beyond the front and back chassis end edges 236 and 238 or they may be co-terminus. The front and back belt side edges 437 may extend laterally beyond the chassis side edges 237a and 237b. The front and back belts 430f and 430b may be continuous (i.e., having at least one layer that is continuous (see 434 in FIG. 7E) from belt end edge 438f to the opposite belt end edge 438b). Alternatively, the front and back belts 430f and 430b may be discontinuous from belt end edge 438f to the opposite belt end edge 438b (see 432 and 434 in FIG. 7D), such that they are discrete.

    [0066] As disclosed in U.S. Pat. No. 7,901,393, the longitudinal length (along the central longitudinal axis 42) of the back belt 430b may be greater than the longitudinal length of the front belt 430f, and this may be particularly useful for increased buttocks coverage when the back belt 430b has a greater longitudinal length versus the front belt 430f adjacent to or immediately adjacent to the side seams 172. Alternatively, the bottom corners of the longer back belt may be trimmed in diagonal lines or curves.

    [0067] The front and back belts 430f and 430b may include slits, holes, and/or perforations providing increased breathability, softness, and a garment-like texture. Underwear-like appearance can be enhanced by substantially aligning the waist and leg edges at the side seams 172.

    ARRAYS



    [0068] "Array" means a display of packages comprising disposable absorbent articles of different article constructions (e.g., different elastomeric materials [compositionally and/or structurally] in the side panels, side flaps and/or belts flaps, different graphic elements, different product structures, fasteners or lack thereof, sizes, core capacities, etc.). The packages may have the same brand and/or sub-brand and/or the same trademark registration and/or having been manufactured by or for a common manufacturer and the packages may be available at a common point of sale (e.g. oriented in proximity to each other in a given area of a retail store). An array is marketed as a line-up of products normally having like packaging elements (e.g., packaging material type, film, paper, dominant color, design theme, etc.) that convey to consumers that the different individual packages are part of a larger line-up. Arrays often have the same brand, for example, "Huggies," and same sub-brand, for example, "Pull-Ups." A different product in the array may have the same brand "Huggies" and the sub-brand "Little Movers." The differences between the "Pull-Ups" product of the array and the "Little Movers" product in the array may include product form, application style, different fastening designs or other structural elements intended to address the differences in physiological or psychological development. Furthermore, the packaging is distinctly different in that "Pull-Ups" is packaged in a predominately blue or pink film bag and "Little Movers" is packaged in a predominately red film bag.

    [0069] Further regarding "Arrays," as another example an array may be formed by different products having different product forms manufactured by the same manufacturer, for example, "Kimberly-Clark", and bearing a common trademark registration for example, one product may have the brand name "Huggies," and sub-brand, for example, "Pull-Ups." A different product in the array may have a brand/sub-brand "Good Nites" and both are registered trademarks of The Kimberly-Clark Corporation and/or are manufactured by Kimberly-Clark. Arrays also often have the same trademarks, including trademarks of the brand, sub-brand, and/or features and/or benefits across the line-up. "On-line Array" means an "Array" distributed by a common on-line source.

    TRANSVERSE BARRIER



    [0070] As shown in FIG. 13, the transverse barrier 16 may extend parallel with the lateral axis 44 and may be joined via bonds 13 to the cuffs 150 and joined by bonds 14 to the topsheet 124 such that the transverse barrier extends in a Z direction away from the topsheet when the article (e.g., 500) is opened and worn. More particularly, the transverse barrier 16 may extend in a Z direction due in part to the cuffs standing upward in the Z direction as the article is opened for wear. The transverse barrier 16 may prevent fecal matter from migrating into the front waist region 36. Thus, the transverse barrier 16 may be oriented proximate to where the front waist region 36 and crotch region 37 meet, or may be disposed between the juncture of where the front waist region 36 and the crotch region 37 meet and the lateral axis 44. Offsetting the bond locations 13 and 14 will influence the angle of the transverse barrier 16 relative to the topsheet 124. The bond locations 13 and 14 may be oriented such that the transvers barrier extends in a Z direction that is approximately 90 degrees from the surface of the topsheet 124.

    FEMININE HYGIENE ARTICLE



    [0071] Referring to FIGS. 11-12C, absorbent articles of the present disclosure may be a feminine hygiene article 801 also referred to as a sanitary napkin, and includes feminine pads, and liners. The sanitary napkin 801 may comprise a liquid permeable topsheet 124, a liquid impermeable, or substantially liquid impermeable, backsheet 125 and an absorbent core 128. The liquid impermeable backsheet 125 may or may not be vapor permeable. The absorbent core 128 may have any or all of the features described herein with respect to the absorbent core 128 and, in some forms, may have a secondary topsheet 124' (STS) instead of the acquisition materials disclosed above. The STS 124' may comprise one or more channels, as described above (including the embossed version). In some forms, channels in the STS 124' may be aligned with channels in the absorbent core 128. The sanitary napkin 801 may also comprise wings 120 extending outwardly with respect to a longitudinal axis 42 of the sanitary napkin 801. The sanitary napkin 801 may also comprise a lateral axis 44. The wings 120 may be integral to TS, BS joined to the topsheet 124, the backsheet 125, and/or the absorbent core 128.

    ABSORBENT ARTICLE PACKAGING AND PACKAGE INDICIA



    [0072] The absorbent articles 100 of the present disclosure are placed into packages 610 (shown in FIG. 26 as dotted lines so the absorbent articles 100 may be seen). The packages may comprise polymeric films and/or other materials. Graphics and/or indicia 1000 relating to properties of the absorbent articles may be formed on, printed on, positioned on, and/or placed on outer portions of the packages. Each package comprises a plurality of absorbent articles 100. The absorbent articles 100 may be packed under compression so as to reduce the size of the packages, while still providing an adequate amount of absorbent articles per package. By packaging the absorbent articles under compression, caregivers can easily handle and store the packages 610, while also providing distribution savings to manufacturers owing to the size of the packages. Accordingly, packages 610 of the absorbent articles 100 of the present disclosure may have an In-Bag Stack Height as disclosed in U.S. Publication No. 2014/0052088 to Weisman, titled ABSORBENT PRODUCTS HAVING IMPROVED PACKAGING EFFICIENCY.

    [0073] Desirably, the package 610 has parallel sides and a package top that is parallel to the package bottom, making the package ideal for stacking on a shelf for storage or for display in a store for purchase by consumers. Typically packages 610 of absorbent articles 100 are labeled with a recommended wearer weight range (typically for babies, infants, and toddlers) and/or by waist circumference (typically for adult absorbent article products) that the packaged article is intended to fit. As a result, the weight and/or the waist circumference information is most often placed on the package 610 as part of the indicia 1000 to identify the appropriate size of the article needed by the consumer.

    [0074] Further, the indicia 1000 may illustrate the wearer wearing the article and/or a separate indicia may illustrate the article component or feature. Regarding absorbent articles for babies, descriptions of suitable stages of development indicia and methods of displaying packages comprising absorbent articles may be found in U.S. Patent No. 7,222,732 to Ronn, titled MERCHANDISE DISPLAY SYSTEM FOR IDENTIFYING DISPOSABLE ABSORBENT ARTICLE CONFIGURATIONS FOR WEARERS.

    PROCESS



    [0075] Referring to FIGS. 14 and 14A, a plurality of elastic strands 316 (from about 10 strands to about 1500 strands having a decitex from about 10 to about 500) unwind about a first axis of rotation 346 from a first beam 314 (which is a first metering device 310) in the machine direction MD and transfer the plurality of elastic strands 316 from the first beam 314 (e.g., a warp beam) to a second metering device 312 (which includes a first roller 324 having a second axis of rotation 328 and a second roller 331 having a third axis of rotation 334, which form a nip 336). The plurality of elastic strands 316 may be stretched along the machine direction MD between the first metering device 310 and the second metering device 312 to prestrain the plurality of elastics 316 (from about 50% to about 400%). The stretched elastic strands 316 may be joined via an adhesive 350 from an adhesive applicator 349 (or the plurality of elastics 316 may be joined via other suitable means) with a first substrate layer 306 and a second substrate layer 308 at the second metering device 312 to produce an elastomeric laminate 302, such that each of the strands are spaced (in the CD) in the elastomeric laminate from about 0.25 mm to about 4 mm. It is this process that forms the elastomeric laminate 302 of the present disclosure and that may be further incorporated into the various absorbent article components such as the belts, ear panels, side panels, transverse barriers, topsheets, backsheets, cuffs, waistbands, waistcaps, and/or chassis to offer the benefits described in this patent application. Further details of the process of creating beamed elastomeric laminate(s) for use in disposable absorbent articles are disclosed in U.S. Publication Number 62/436,589, titled "METHODS AND APPARATUSES FOR MAKING ELASTOMERIC LAMINATES WITH ELASTIC STRANDS UNWOUND FROM BEAMS," first-named inventor being Schneider, filed on December 20, 2016. The elastomeric laminate 302 may be produced as part of the absorbent article manufacturing line, or may be produced offline, and unwound as an elastomeric laminate that is fed into the absorbent article manufacturing line.

    MULTIPLE BEAMS



    [0093] It should be appreciated that one or more of a waistband 122, waistcap 123, inner leg cuff 150, outer leg cuff 140 and/or a transverse barrier may be formed from multiple beams of elastic. For example, one beam may form a first portion of one or more of a waistband 122, waistcap 123, inner leg cuff 150, outer leg cuff 140 and/or a transverse barrier and a second beam may form a second portion of one or more of a waistband 122, waistcap 123, inner leg cuff 150, outer leg cuff 140 and/or a transverse barrier, where the separate beams may comprise a different number of elastics, and/or the beams may have elastics having different decitex, and/or the elastics of the two beams may be disposed at different spacing, and/or the separate beams may deliver elastics having different pre-strain, and/or the different beams may deliver elastics having different orientations in the product, e.g. liner, arcuate, angled, etc. The resultant portions of the waistband 122, waistcap 123, inner leg cuff 150, outer leg cuff 140 and/or transverse barrier created from such a multi-beam approach may have different texture, garment-like appearance, modulus and/or different force.

    [0094] It is also to be appreciated that one or more of the absorbent article components including a belt 430, side panel 330, ear panel 530, waistband 122, chassis 200, topsheet 124 and backsheet 125, may comprise an elastomeric laminate 302 formed from multiple beams of elastic. For example, one beam may form a first portion of one or more absorbent article components including a belt 430, side panel 330, ear panel 530, waistband 122, chassis 200, topsheet 124 and backsheet 125, and a second beam may form a second portion of an absorbent article component including a belt 430, side panel 330, ear panel 530, waistband 122, chassis 200, topsheet 124 and backsheet 125. The separate beams may comprise a different number of elastics and the beams may have a plurality of elastics 316 having different decitex. The elastics of the two beams may be disposed at different spacing and/or the separate beams may deliver elastics having different pre-strain and/or the different beams may deliver elastics having different orientations in the product, e.g. liner, arcuate, angled, etc. The resultant portions of the absorbent article components including a belt 430, side panel 330, ear panel 530, waistband 122, chassis 200, topsheet 124 and/or backsheet 125 created from such a multi-beam approach may have different texture, garment-like appearance, modulus and/or different force.

    LATERALLY EXTENDING ELASTICS



    [0095] A wearable article of the present disclosure may comprise one or more elastomeric laminates 302 having a plurality of laterally extending a plurality of elastics , where the one or more elastomeric laminates may be present in a first waist region, the crotch region and/or in the opposing second waist region, and where the plurality of elastics 316 may be disposed in one or both of the first and second waist regions may have one or more of a higher elastic decitex, higher percent strain, and smaller Average-Strand-Spacing than some or all of the laterally extending a plurality of elastics disposed in the crotch region. Such a wearable article may comprise one or more elastomeric laminates 302 having a plurality of elastics 316 having from about 100 to about 1500 elastic strands with an Average-Strand-Spacing from about 0.25 mm to about 4 mm, a decitex from about 10 to about 500, an elastic Average-Pre-Strain from about 50% to about 400%, and a first substrate 306 and/or second substrate 308 each having a basis weight from about 6 grams per square meter to about 30 grams per square meter.

    CHEMISTRY (SPANDEX vs. EXTRUDED STRANDS) AND STRUCTURE



    [0096] Beamed elastic uses Spandex fibers. One type of Spandex fiber is "PolyUrethane Urea" elastomer or the "high hard segment level PolyUrethane" elastomer, which must be formed into fibers using a solution (solvent) spinning process (as opposed to being processable in the molten state.) The Urea linkages in PolyUrethane Urea provides strong mutual chemical interactions crucial for providing "anchoring" that enables good stress relaxation performance at temperatures near body temperature on timescales corresponding to diaper wear, including overnight. This type of anchoring enables better force relaxation (i.e. little force decay with time when held in stretched condition at body temperature) over many thermoplastic polyurethane (PolyUrethane with hard segment melting below 200 deg. C) or thermoplastic Styrenic block copolymers.

    [0097] In contrast, extruded strands and scrims are typically made of Styrenic block copolymers or thermoplastic elastomers that can be formed in the molten state by conventional extrusion processes. Thermoplastic elastomers include compositions like polyolefin, polyurethane (PolyUrethane with hard segment melting below 200 deg. C) elastomers, etc. Because these thermoplastic elastomers like Polyurethane (PolyUrethane with hard segment melting below 200 deg. C) can be melted/remelted, and extruded it makes them susceptible to higher stress relaxation in use, which is a major negative. The styrenic block copolymers used in extruded strands comprise a comparatively long rubbery midblock situated between comparatively short end blocks. End blocks sufficiently short to enable good flow conventional extrusion processes often have a greater propensity to stress relax and undergo force relaxation over time see Fig. 25.

    [0098] The Urea linkage present in Spandex requires it to be made by spinning process. Spandex can't be melted/remelted or extruded like Styrenic block copolymers. Spandex pre-polymer is combined with solvent and additives, and the solution is spun to make solid spandex fiber. Multiple fibers are then formed together to make one spandex strand. The Spandex strands may have surface finish to avoid blocking and wound onto spools. The one spandex fiber may have a decitex of about 15, so a 500 decitex strand may have nominally 33 fibers wound together to make one strand. Depending on the decitex we use for beam approach, we may have 15 fibers (or filaments), 8 fibers, 5 fibers, 3 fibers or even as low as 2 fibers. Spandex fiber can be mono-component or bi-component (as disclosed in WO201045637A2).

    [0099] Further related to the chemistry of beamed elastics, it may be desirable to coat the beamed elastics with an oil, such as a silicone oil, including about 10%, about 7%, about 5%, about 3%, or about 1% silicone oil. Treating the beamed elastics with silicone oil helps to prevent blocking (cross-linking) when the strands are wound to a spool or a beam and it also lowers the COF for the strand in textile machinery (for weaving, knitting and warping processes).

    [0100] Commercially available Spandex strands may also be known as Lycra, Creora, Roica, or Dorlastan. Spandex is often referred as Elastan fiber or Polyurethane fiber.

    [0101] LYCRA HYFIT strands, a product of Invista, Wichita, Kansas, are a suitable for making the strands that make up the plurality of elastics 316 that make up the elastomeric laminate 302. Some strands, for example, the aforementioned LYCRA HYFIT, may comprise a number of individual fibers wound together to form the strand. With regard to elastic strands formed of a number of individual fibers it has been discovered that the individual fibers can move relative to each other changing the cross sectional shape of the strand as well as becoming unraveled which can lead to poor control of the strands as well as poor bonding/adhering/joining of the elastic strands to one or both of the first substrate layer 306 and second substrate layer 308 of the elastomeric laminate 302. In order to minimize the negatives with regard to strands comprising a plurality of fibers it would be advantageous to minimize the number of fibers in a given strand. It would therefore be desirable to have less than about 40 fibers per strand, less than about 30 fibers per strand, less than about 20 fibers per strand, less than about 10 fibers per strand, less than about 5 fibers per strand and 1 fiber forming the strand. In the case of a single fiber forming the strand which can deliver comparable performance to the multi-fiber strands of the prior art it would be desireable for the fiber to have a fiber decitex from about 22 to about 300 and a fiber diameter from about 50 micrometers to about 185 micrometers.

    BEAMED ELASTOMERIC LAMINATE EXAMPLES



    [0102] Consumer interactions and research has shown that a longstanding unmet consumer need exists to provide absorbent articles which have the right balance of modulus for application and removal ease and freedom of movement while providing an article with low elastic pressure (relative to today's stranded products) to provide a comfortable wearing experience free from skin marks. It has been found that elastomeric laminate structures having a modulus of between about 2 gf/mm and 15 gf/mm, alternatively from about 3 gf/mm to about 12 gf/mm, in another alternative from about 4 gf/mm to about 10 gf/mm, are most desirable for ease of application, ease of removal, conforming fit and freedom of movement. Depending on the elastic configuration in these structures they may exhibit very high Pressure-Under-Strand, e.g., elastic strands, leading to increased skin marking and reduced comfort. One approach to reduce the pressure of the elastic on the skin is to increase the number of elastics for a given area. Increasing the number of elastics within a given area alone may reduce the Pressure-Under-Strand, however, if that is the only change it can also significantly increase the overall modulus of the elastomeric laminate structure. In order to achieve the right balance of modulus and pressure on the skin it is necessary to reduce the elastic decitex and/or the elastic strain as the spacing between the elastics is reduced thereby increasing the elastic number in order to balance the modulus and pressure on the skin and maintain these parameters within the consumer preferred range. This breakthrough has been enabled through delivery of very low decitex elastic at very low strain levels and with very tight elastic spacing that have never before been seen in disposable absorbent articles. Delivery of such low decitex elastic at low strain and tight spacing is enabled via a new to absorbent article technology created from the textile warp beam technology approach. The examples below are some embodiments of such elastomeric structures.

    [0111] FIGS. 23 and 24 illustrate the interdependence between: Average-Dtex; Average-Strand-Spacing; Section-Modulus; Donning-Ratio and Pressure-Under-Strand, and how the unique properties enabled by the elastomeric laminates of the present invention are able to deliver low pressure on the skin, comfortable fit and donning ease while delivering a sufficient hoop force of 7 gf/mm providing sustained fit and gasketing of the article. While this particular example utilizes an Average-Dtex of 150 and a hoop pressure on the body of 7 gf/mm, the relative relationships between the various metrics remain consistent. FIG. 23 shows that as strand spacing decreases, the Donning-Ratio lessens (making donning easier) due to lower required Average-Pre-Strain needed to deliver the 7 gf/mm thereby enabling improved donning while maintaining the requisite forces for fit and gasketing. FIG. 24 shows that as the Average-Strand-Spacing decreases, the corresponding Pressure-Under-Strand decreases while maintaining a hoop pressure on the body of 7 gf/mm thereby maximizing overall comfort and skin health while maintaining the requisite forces for fit and gasketing of the article.

    METHODS


    General Sample Preparation



    [0116] The General Sample Preparation is intended to be used for methods that do not have specific sample preparation instructions within the method itself.

    [0117] The When collecting a specimen for testing, the specimen must contain a plurality of elastic strands and/or an elastic material; film, elastic scrim, elastic foam, elastic ribbons, elastic strips, etc. In situations where the elastic material and/or elastic strands is not fully secured within the sample, the test specimen must be obtained in a way that elastic material and/or elastic strands within the test region of the specimen are as they were intended and not altered as a result of collection of the specimen. If the elastic material or any elastic strands release, creep or become separated within or from the laminate, the specimen is discarded and a new specimen prepared.

    [0118] For pants, remove the side panels where they are attached to the chassis and separate the side panels at the side seams. Identify the elastic material that transverses the entire width of the panel. Identify the longitudinally distal most edge of the elastic material or elastic strand (closest to the waist edge) and the longitudinally proximal most edge of the elastic material or elastic strand (closest to the leg edge) determine the midpoint between the distal most elastic strand or elastic material edge and the proximal most elastic strand or elastic material edge. Cut a 40 mm wide strip laterally across the entire panel centered at the midpoint. Repeat for each front and rear side panel that contains elastic material and/or elastic strands.

    [0119] For taped, remove ear panels where they are attached to the chassis. Identify the elastic material that transverses the entire width of the panel. Identify the distal most elastic material edge or elastic strand (closest to the waist edge) and the proximal most elastic material edge or elastic strand (closest to the leg edge) determine the midpoint between the distal most elastic strand or elastic material edge and the proximal most elastic strand or elastic material edge. Cut a 40 mm wide strip laterally across the entire ear panel centered at the midpoint. Repeat for each front and rear ear panel that contains elastic material and/or elastic strands.

    [0120] For a belted article, mark the product on the front and back by extending a line from along the side of the core to the waist edge. Remove the belt from the article, using an appropriate means (e.g. freeze spray), taking care not to delaminate the belt or release the elastics. Separate the front belt from the back belt along any seams. Identify the distal most elastic material edge or elastic strand (closest to the waist edge) and the proximal most elastic material edge or strand (closest to the leg edge) determine the midpoint between the distal most elastic strand or elastic material edge and the proximal most elastic strand or elastic material edge. Cut a 40 mm wide strip parallel to the waist edge if linear or to the elastic strands if linear and centered at the midpoint, across the entire belt portion. If the strip has a region that does not contain elastic strands or elastic material (e.g., a portion that overlapped the core, etc.) cut along the ends of the elastic strands/elastic material, to remove the non-elastic region and treat as two specimens.

    [0121] For waistbands, they are tested as a single piece of material. Remove the belt from the article, using an appropriate means (e.g. freeze spray), taking care not to delaminate the belt or release the elastics.

    [0122] For the leg cuffs, each of the leg cuffs are tested as a single piece of material. The inner leg cuff sample is considered to be the portion of the inner leg cuff that extends from the proximal most edge of the inner leg cuff to and including the distal most elastic of the inner leg cuff and extending longitudinally to the front and back waist edges of the chassis. The outer leg cuff sample is considered to be the portion of the outer leg cuff that extends from the distal most edge of the outer leg cuff to and including the proximal most elastic of the outer leg cuff and extending longitudinally to the front and back waist edges of the chassis.

    [0123] For all specimen strips calculate a Span Corrected Width (SCW) is calculated as:

    where d is the distance (mm) between the two distal strands, and n is the number of strands, when n >1. Clamp the strip at each end and measure the length between the clamps to the nearest 1 mm. Apply a weight equal to 3g/mm SCW. After 10 seconds measure the final weight to the nearest 1 mm. Calculate the elongation as (Final Length - Initial Length) / Initial length.

    PRODUCT MEASUREMENT PREPARATION FOR DONNING-RATIO, PRODUCT LENGTH-TO-WAIST SILHOUETTE AND PRODUCT HIP-TO-WAIST SILHOUETTE



    [0124] All measurements are conducted at 22° C +/- 2° and 50% RH +/- 20%.

    Purpose



    [0125] This method is used to prepare pant type products for subsequent dimensional measurement. The method provides a consistent means of opening a product that has been removed from a bag. This method is applicable to all forms of pant products. A constant rate of extension tensile testing machine with computer interface is used.

    [0126] A load cell is chosen so that the load cell capacity ensures accuracy of a 5N load to within 0.1N.

    Sample Holder Apparatus

    [0129] The initial gauge length is determined by removing 10 sample products from the bag, unfolding the pant products (607) and laying them flat as illustrated in FIG. 21, below and measuring the distance between the sides of the pant at the waist as shown (606). The average of the waist measurement will be used as the initial gauge length for the specific set of specimens. The initial gauge length is the distance from the uppermost edge of the upper bar to the lowermost edge of the lower bar.

    [0130] Apply the whole product (607) to the bars as shown in FIG. 22 while minimizing manipulation of the specimen.

    [0131] Pull Sample to 5N Force then hold for 10 seconds. Return to initial gauge length.

    [0132] Crosshead Speed = 254.0 mm/min, Data acquisition rate = 50 Hz.

    [0133] Cycles = 1

Refer to FIG. 2. The lateral distance is measured perpendicular to the longitudinal axis of the product.

    AVERAGE-STRAND-SPACING



    [0141] Using a ruler calibrated against a certified NIST ruler and accurate to 0.5 mm, measure the distance between the two distal strands within a section to the nearest 0.5 mm, and then divide by the number of strands in that section - 1

    [0142] Average-Strand-Spacing = d/(n-1) where n>1

    [0143] report to the nearest 0.1 mm.

    PRESSURE-UNDER-STRAND (ALSO REFERRED TO AS AVERAGE PRESSURE-UNDER-STRAND)



    [0144] Defined as the average pressure imparted by each individual elastic strand of a section under specific conditions. These conditions are defined as (refer to FIG. 16):
    • The section is pulled to a Stress of 7 gf/mm (within a consumer preferred range of stresses as determined experimentally)
    • The section is pulled over a cylinder whose circumference is defined as a Representative-Circumference


    [0145] Where:
    • Pressure-Under-Strand (psi) = 1.422 Strand-Force / (2 Representative-Radius Average-Strand-Diameter)
    • Representative-Radius (mm) = Representative-Circumference / (2 pi)
    • Representative-Circumference(mm) = 460 mm
    • Stress (gf/mm) = (Summation of Strand-Forces within a section) / (Section-Width)
    • Section-Width (mm) = (Number of Elastics in the section) Average-Strand-Spacing (mm)
    • Strand-Force (gf) = Strand-Strain (%) 0.046875 Average-Dtex
    • Strand-Strain (%) = strain in each elastic strand within a section
    • Average-Strand-Diameter (mm) = 2 sqrt (Strand-Cross-Sectional-Area / pi)
    • Strand-Cross-Sectional-Area (mm2) = Average-Dtex / Strand-Density / 10,000
    • Strand-Density (g/cc) = 1.15 g/cc (industry standard for PolyUrethaneUrea based spandex elastics)
    • Dtex (g/10,000m) = Standard textile unit of measure. Dtex is weight in grams for 10,000m of the material
    • Average-Pre-Strain = Amount of stretch in elastic strands in a section prior to combining with substrate layer(s).
    • Maximum-Strain = Average-Pre-Strain. This is the maximum amount of strain each section can be pulled to. It cannot exceed the Average-Pre-Strain.
    • Maximum-Section-Force = Summation of each strand in the section pulled to the Maximum-Strain.

    SECTION-MODULUS



    [0146] Defined as the modulus of a given section. Section-Modulus (also referred to as modulus) is the linear slope of the stress vs strain data of the section between 3 gf/mm and 7 gf/mm (refer to FIG. 15). Section-Modulus is calculated as:



    [0147] Where:
    • section strain at 7gf/mm = 7gf/mm (Average-Strand-Spacing)/DTEX-FACTOR
    • section strain at 3gf/mm = 3gf/mm (Average-Strand-Spacing)/DTEX-FACTOR
    • Average-Strand-Spacing (mm)= d/(n-1)
    • d is the distance (mm) between the two distal strands of the section
    • n is the number of strands, when n >1
    • DTEX-FACTOR = 37.5 Average-Dtex/800 (dtex as measured, specified)
    • Section-Modulus is reported in units of (gf/mm)

    AVERAGE DECITEX (AVERAGE-DTEX)



    [0148] The Average Decitex Method is used to calculate the Average-Dtex on a length-weighted basis for elastic fibers present in an entire article, or in a specimen of interest extracted from an article. The decitex value is the mass in grams of a fiber present in 10,000 meters of that material in the relaxed state. The decitex value of elastic fibers or elastic laminates containing elastic fibers is often reported by manufacturers as part of a specification for an elastic fiber or an elastic laminate including elastic fibers. The Average-Dtex is to be calculated from these specifications if available. Alternatively, if these specified values are not known, the decitex value of an individual elastic fiber is measured by determining the cross-sectional area of a fiber in a relaxed state via a suitable microscopy technique such as scanning electron microscopy (SEM), determining the composition of the fiber via Fourier Transform Infrared (FT-IR) spectroscopy, and then using a literature value for density of the composition to calculate the mass in grams of the fiber present in 10,000 meters of the fiber. The manufacturer-provided or experimentally measured decitex values for the individual elastic fibers removed from an entire article, or specimen extracted from an article, are used in the expression below in which the length-weighted average of decitex value among elastic fibers present is determined.

    [0149] The lengths of elastic fibers present in an article or specimen extracted from an article is calculated from overall dimensions of and the elastic fiber pre-strain ratio associated with components of the article with these or the specimen, respectively, if known. Alternatively, dimensions and/or elastic fiber pre-strain ratios are not known, an absorbent article or specimen extracted from an absorbent article is disassembled and all elastic fibers are removed. This disassembly can be done, for example, with gentle heating to soften adhesives, with a cryogenic spray (e.g. Quick-Freeze, Miller-Stephenson Company, Danbury, CT), or with an appropriate solvent that will remove adhesive but not swell, alter, or destroy elastic fibers. The length of each elastic fiber in its relaxed state is measured and recorded in millimeters (mm) to the nearest mm.

    Calculation of Average-Dtex



    [0150] For each of the individual elastic fibers fi of relaxed length Li and fiber decitex value di (obtained either from the manufacturer's specifications or measured experimentally) present in an absorbent article, or specimen extracted from an absorbent article, the Average-Dtex for that absorbent article or specimen extracted from an absorbent article is defined as:

    where n is the total number of elastic fibers present in an absorbent article or specimen extracted from an absorbent article. The Average-Dtex is reported to the nearest integer value of decitex (grams per 10 000 m).

    [0151] If the decitex value of any individual fiber is not known from specifications, it is experimentally determined as described below, and the resulting fiber decitex value(s) are used in the above equation to determine Average-Dtex.

    Experimental Determination of Decitex Value for a Fiber



    [0152] For each of the elastic fibers removed from an absorbent article or specimen extracted from an absorbent article according to the procedure described above, the length of each elastic fiber Lk in its relaxed state is measured and recorded in millimeters (mm) to the nearest mm. Each elastic fiber is analyzed via FT-IR spectroscopy to determine its composition, and its density ρk is determined from available literature values. Finally, each fiber is analyzed via SEM. The fiber is cut in three approximately equal locations perpendicularly along its length with a sharp blade to create a clean cross-section for SEM analysis. Three fiber segments with these cross sections exposed are mounted on an SEM sample holder in a relaxed state, sputter coated with gold, introduced into an SEM for analysis, and imaged at a resolution sufficient to clearly elucidate fiber cross sections. Fiber cross sections are oriented as perpendicular as possible to the detector to minimize any oblique distortion in the measured cross sections. Fiber cross sections may vary in shape, and some fibers may consist of a plurality of individual filaments. Regardless, the area of each of the three fiber cross sections is determined (for example, using diameters for round fibers, major and minor axes for elliptical fibers, and image analysis for more complicated shapes), and the average of the three areas αk for the elastic fiber, in units of micrometers squared (µm2), is recorded to the nearest 0.1 µm2. The decitex dk of the kth elastic fiber measured is calculated by:

    where dk is in units of grams (per calculated 10,000 meter length), αk is in units of µm2, and ρk is in units of grams per cubic centimeter (g/cm3). For any elastic fiber analyzed, the experimentally determined Lk and dk values are subsequently used in the expression above for Average-Dtex.

    OPEN AREA



    [0153] Defined as the percentage of a Section not occluded by elastic strands. Un-apertured films have an Open Area 0%. Apertured film Open Area = (area occupied by apertures) / (total film area). None of today's marketed disposable absorbent articles comprising a film in one or more of a belt, sided panel, or ear panel, waistband, cuff, wing are believed to have and Open Area above 50%.

    [0154] Open Area is defined as:


    AVERAGE-PRE-STRAIN



    [0155] The Average-Pre-Strain of a specimen are measured on a constant rate of extension tensile tester (a suitable instrument is the MTS Insight using Testworks 4.0 Software, as available from MTS Systems Corp., Eden Prairie, MN) using a load cell for which the forces measured are within 1% to 90% of the limit of the cell. Articles are conditioned at 23 °C ± 2 C° and 50% ± 2% relative humidity for 2 hours prior to analysis and then tested under the same environmental conditions.

    [0156] Program the tensile tester to perform an elongation to break after an initial gage length adjustment. First raise the cross head at 10 mm/min up to a force of 0.05N. Set the current gage to the adjusted gage length. Raise the crosshead at a rate of 100 mm/min until the specimen breaks (force drops 20% after maximum peak force). Return the cross head to its original position. Force and extension data is acquired at a rate of 100 Hz throughout the experiment.

    [0157] Set the nominal gage length to 40 mm using a calibrated caliper block and zero the crosshead. Insert the specimen into the upper grip such that the middle of the test strip is positioned 20 mm below the grip. The specimen may be folded perpendicular to the pull axis, and placed in the grip to achieve this position. After the grip is closed the excess material can be trimmed. Insert the specimen into the lower grips and close. Once again, the strip can be folded, and then trimmed after the grip is closed. Zero the load cell. The specimen should have a minimal slack but less than 0.05 N of force on the load cell. Start the test program.

    [0158] From the data construct a Force (N) verses Extension (mm). The Average-Pre-Strain is calculated from the bend in the curve corresponding to the extension at which the nonwovens in the elastic are engaged. Plot two lines, corresponding to the region of the curve before the bend (primarily the elastics), and the region after the bend (primarily the nonwovens). Read the extension at which these two lines intersect, and calculate the % Pre-Strain from the extension and the corrected gage length. Record as % Pre-strain 0.1%. Calculate the arithmetic mean of three replicate samples for each elastomeric laminate and Average-Pre-Strain to the nearest 0.1%.

    FORCE RELAXATION OVER TIME



    [0159] The Force Relaxation over Time of a specimen is measured on a constant rate of extension tensile tester (a suitable instrument is the MTS Insight using Testworks 4.0 Software, as available from MTS Systems Corp., Eden Prairie, MN) using a load cell for which the forces measured are within 1% to 90% of the limit of the cell. Articles are conditioned at 23 °C ± 2 C° and 50% ± 2% relative humidity for 2 hours prior to analysis and then tested under the same environmental conditions. Prepare a sample size such that it enables a gauge length of 25.4 mm (parallel to the elastic stretch) at a width of 12.7 mm.

    [0160] Program the tensile tester to perform an elongation to determine the engineering strain at which the tensile force reaches 0.0294 N/mm.

    [0161] Prepare and condition a second sample as described above for the Force Relaxation over time test. The test is performed on the same equipment as described above. It is performed at a temperature of 37.8° C. Extend the sample to the strain as determined above. Hold the sample for 10 hours and record the force at a rate of 100 Hz throughout the experiment a chart showing the data for an extruded strand prior art product and an inventive elastomeric laminate comprising beam elastic as described herein is show in FIG.25.
