Description

Field of the Invention

[0001] The present invention relates to terry fabric weaves, methods for weaving terry fabrics comprising such weaves, and resulting terry fabrics. In particular, the invention relates to terry fabrics having improved material efficiencies, pull resistance, absorbency, softness and uniformity of texture.

Background

[0002] Terry fabrics are manufactured for several different end uses, including as towels, bathrobes, blankets, cleaning products, carpets and the like. Terry fabrics are considered advantageous in view of the fast drying, softness, ability to pick up particles, and ability to absorb moisture.

[0003] Terry fabrics typically comprise a woven ground fabric comprising a plurality of substantially parallel ground warp yarns and a plurality of substantially parallel ground weft yarns (or picks) - wherein the plurality of ground weft yarns intersect the plurality of ground warp yarns substantially perpendicularly. Additionally, a plurality of pile warp yarns are interwoven into the ground fabric in a direction substantially parallel to the ground warp yarns - and the pile weave forms a plurality of pile loops or terry loops above and below the woven ground fabric.

[0004] Ground warp yarns are interwoven with ground weft yarns at a relatively high tension and forms the base or substrate of the terry fabric. The pile warp yarns are interwoven at a lower tension and are advanced or "let off" from the loom beam at a higher rate than the ground warp yarns. During weaving, a series of adjacent ground weft yarns are subjected to a partial beat-up or "loose beat-up", where the weft yarn(s) may be pushed partially together using a comb (or "reed") or where the fell of the cloth is moved forward to enable a partial beat-up, while the pile warp yarns are permitted to "float" over two or more adjacent ground weft yarns. On an ensuing ground weft yarn (at the conclusion of a weaving repeat), the previously partially beat up ground weft yarns as well as the ensuing ground weft yarn are subjected to a "fast beat up", where all ground weft yarns are pushed fully up to the fell of the woven fabric - resulting in the floating pile threads forming loops that extend away from the ground substrate. A common terry pattern comprises a 3 pick sequence, wherein pile loops are interwoven into the ground fabric in a repeating pattern such that pile loops are formed using (and repeated every) 3 ground weft yarns. Less commonly known are 4, 5, 6 and 7 pick sequences - where interweaving a pile yarn into the ground fabric comprises repeating a pile loop every 4, 5, 6, or 7 ground weft yarns.

[0005] Figures 1 and 2 respectively provide transverse and perspective views of a terry weave sequence 100 comprising a 3 pick sequence. Terry weave sequence 100 comprises a pair of ground warp yarns 102a and 102b interwoven with a plurality of ground weft yarns in a repeating sequence such that first and second ground weft yarns 104a and 104b are placed within a first shed 106a formed by the pair of ground warp yarns, and a third ground weft yarn 104c is placed within a second shed 106b formed by the pair of ground warp yarns. Said repeating sequence forms a ground fabric on ground substrate terry weave sequence 100 additionally comprises pile yarns 108a and 108b wherein each of said pile yarns are interwoven into the ground substrate in a sequence that repeats every 3 ground weft yarns. The 3 pick sequence can be observed in case of pile loop 110a which is formed over the sequence of ground weft yarns 104a, 104b and 104c, and in case of pile loop 110b which is also formed over the sequence of ground weft yarns 104a, 104b and 104c. It would be understood from Figures 1 and 2 that in forming pile loop 110a,pile yarn 108a passes between ground weft yarns 104a and 104b and thereafter forms a pile loop over ground weft yarns 104b and 104c (i.e. on the top surface / face surface of the ground substrate), before the next 3 pick sequence is commenced. Likewise, in forming pile loop 110b, pile yarn 108b passes between ground weft yarns 104a and 104b and thereafter forms a pile loop over ground weft yarns 104b and 104c (i.e. on the bottom surface / back surface of the ground substrate), before the next 3 pick sequence is commenced.

[0006] While prior art weave sequences have been widely used in the past, it is desired to increase pick density of terry fabrics beyond the pick densities permitted by prior art weave sequences, as well as to improve pull resistance, absorbency, softness and uniformity of texture of the terry fabrics.

Eighth weft yarn 304h is followed by immediately adjacent weft yarn 304i (adjacent weft yarn 304i forms part of a next instance of the first interlacing arrangement within a repeating sequence).

[0030] First pile warp yarn 308a is interlaced within first interlacing arrangement 300A so as to form a first pile loop 310a and a second pile loop 310b. First pile loop 310a is formed over first weft yarn 304a, second weft yarn 304b, third weft yarn 304c and fourth weft yarn 304d.

[0034] As illustrated in Figure 5, first pile loop 310a is formed on a face surface of the ground substrate (i.e. the ground fabric comprising interwoven warp and weft yarns). Simultaneously the opposite surface (i.e. the back surface) of the ground substrate comprises a first region having boundaries defined by (a) first ground warp yarn pair 302a, 302b, (b) second ground warp yarn pair 302c, 302d, (c) first weft yarn 304a and (d) fourth weft yarn 304d - which first region is devoid or free of pile loop formation (i.e. no pile loop is formed over this region on said back surface of the ground substrate).

[0035] Likewise, second pile loop 310b is formed on a back surface of the ground substrate. Simultaneously an opposite surface (i.e. the face surface) of the ground substrate comprises a second region having boundaries defined by (a) first ground warp yarn pair 302a, 302b, (b) second ground warp yarn pair 302c, 302d, (c) fifth weft yarn 304e and (d) eighth weft yarn 304h - which second region is devoid or free of pile loop formation (i.e. no pile loop is provided in this region on said face surface of the ground substrate).

[0036] Additionally, as illustrated in Figure 5, third pile loop 310c is formed on a back surface of the ground substrate. Simultaneously an opposite surface of the ground substrate (i.e. the face surface) comprises a third region having boundaries defined by (a) second ground warp yarn pair 302c, 302d, (b) a third ground warp yarn pair (not shown in Figure 5) that is adjacent to second ground warp yarn pair 302c, 302d, and which is positioned such that second ground warp yarn pair 302c, 302d is interposed between said third ground warp yarn pair and first ground warp yarn pair 302a, 302b, (c) first weft yarn 304a and (d) fourth weft yarn 304d - which third region is devoid or free of pile loop formation (i.e. no pile loop is formed over this region on the face surface of the ground substrate).

[0037] Likewise, fourth pile loop 310d is formed on a face surface of the ground substrate. Simultaneously an opposite surface (i.e. the back surface) of the ground substrate comprises a fourth region having boundaries defined by (a) second ground warp yarn pair 302c, 302d, (b) the third ground warp yarn pair, (c) fifth weft yarn 304e and (d) eighth weft yarn 304h - which fourth region is devoid or free of pile loop formation (i.e. no pile loop is formed over this region on back surface of the ground substrate).

[0038] Additionally, as is apparent from weave sequence 500 as illustrated in Figure 5, first pile loop 310a and third pile loop 310c are respectively formed on opposite surfaces of the ground substrate, while second pile loop 310b and fourth pile loop 310d are respectively formed on opposite surfaces of the ground substrate.

[0039] The terry weave sequence 500 illustrated in Figure 5 shows first ground warp yarn pair 302a, 302b positioned adjacent to second ground warp yarn pair 302c, 302d with only first pile yarn 308a interposed therebetween. For the purposes of the present invention however, one or more additional ground warp yarn pairs may be interposed between first ground warp yarn pair 302a, 302b and second ground warp yarn pair 302c, 302d - provided however that no other pile yarn (i.e. no pile yarn other than first pile yarn 308a) is interposed between first ground warp yarn pair 302a, 302b and second ground warp yarn pair 302c, 302d.

[0040] The illustrations in Figures 3 to 5 illustrate embodiments of the terry weave sequence where first pile yarn 308a forms pile loops alternately on face and back surfaces of the ground substrate, while second pile yarn 308b also forms pile loops alternately on face and back surfaces of the ground substrate. In another embodiment of the invention, illustrated in Figures 6, 7 and 8, the first pile yarn may form pile loops on only one of the face or back surface of the ground substrate while the second pile yarn may form pile loops on only the other of the face or back surface of the ground substrate.

The first ground warp yarn pair comprises warp yarns 602a and 602b that are interlaced and positioned adjacent to first pile warp yarn 608a. The first ground warp yarn pair 602a, 602b is interlaced with ground weft yarns such that first weft yarn 604a, second weft yarn 604b and third weft yarn 604c are positioned within a first shed 606a formed by first ground warp yarn pair 602a and 602b. Additionally, a fourth weft yarn 604d is positioned within a second shed 606b formed by first ground warp yarn pair 602a and 602b.

Eighth weft yarn 604h is followed by immediately adjacent weft yarn 604i.

[0043] First pile warp yarn 608a is interlaced within first interlacing arrangement 600A so as to form a first pile loop 610a and a second pile loop 610b. First pile loop 610a is formed over first weft yarn 604a, second weft yarn 604b, third weft yarn 604c and fourth weft yarn 604d.

[0047] As illustrated in Figure 8, first pile loop 610a is formed on a face surface of the ground substrate (i.e. the ground fabric comprising interwoven warp and weft yarns). Simultaneously the opposite surface (i.e. the back surface) of the ground substrate comprises a first region having boundaries defined by (a) first ground warp yarn pair 602a, 602b, (b) second ground warp yarn pair 602c, 602d, (c) first weft yarn 604a and (d) fourth weft yarn 604d - which first region is devoid or free of pile loop formation (i.e. no pile loop is formed over this region on said back surface of the ground substrate).

[0048] Likewise, second pile loop 610b is formed on a face surface of the ground substrate. Simultaneously an opposite surface (i.e. the back surface) of the ground substrate comprises a second region having boundaries defined by (a) first ground warp yarn pair 602a, 602b, (b) second ground warp yarn pair 602c, 602d, (c) fifth weft yarn 604e and (d) eighth weft yarn 604h - which second region is devoid or free of pile loop formation (i.e. no pile loop is provided in this region on said back surface of the ground substrate).

For the purposes of the present invention however, one or more additional ground warp yarn pairs may be interposed between first ground warp yarn pair 602a, 602b and second ground warp yarn pair 602c, 602d. In an embodiment of the invention, while one or more additional ground warp yarn pairs may be interposed between first ground warp yarn pair 602a, 602b and second ground warp yarn pair 602c, 602d,no other pile yarn (i.e. no pile yarn other than first pile yarn 608a) is interposed between first ground warp yarn pair 602a, 602b and second ground warp yarn pair 602c, 602d.

[0092] The terry weave sequences and terry weave fabrics in accordance with the above embodiments of the invention have been found to present several significant advantages.

[0093] Table A in Figure 16 sets out results of comparative product testing using terry fabrics manufactured in accordance with embodiments of the present invention, in comparison with terry fabrics manufactured in accordance with terry weave sequences known in the prior art.

[0094] Terry fabric A corresponds to a fabric of the kind discussed in connection with Figures 3 to 8, whereas terry fabric E corresponds to a fabric of the kind discussed in connection with Figures 9 to 14. As will be observed, for a given grams per square meter (GSM) value, terry fabrics manufactured in accordance with the present invention exhibit significantly higher pick density, and cover factor (weft). Terry fabric A additionally exhibits absorbency that is comparable to prior art towels despite having a significantly lower loop density. Lower loop density has been found to significantly improve fabric softness of the resulting terry fabric. It would also be observed that terry fabrics A and E use significantly less pile yarn per inch, while offering absorbency that is comparable to prior art terry fabrics - which in presents significant cost and manufacturing efficiencies, particularly since pile yarn is typically more expensive that ground warp and weft yarns. In cases where pile yarn is manufactured using soluble fibers such as polyvinyl alcohol (PVA) fibers, lowering the pile per inch value also offers environmental advantages. Yet further, as is apparent from the data in Table A, terry fabrics manufactured in accordance with the present invention exhibit significantly improved tensile strength.

[0095] In addition to the above, terry fabrics manufactured in accordance with teachings of the present invention have been found to have a distinctive and aesthetically appealing appearance and improved uniformity of texture in comparison with terry fabrics manufactured in accordance with terry weaves known in the prior art. Figure 15B provides a photograph depicting appearance of a terry fabric manufactured in accordance with teachings of the present invention - which appearance is significantly different and aesthetically improved over the terry fabric photographs in Figure 15A, which corresponds to a terry fabric manufactured in accordance with prior art methods.

[0096] The terry fabrics in accordance with the present invention may be manufactured using one or more non-soluble yarns and optionally one or more soluble yarns. Non-soluble yarns for manufacturing terry fabrics in accordance with teachings of the present invention may comprise any one or more natural fibers such as cotton, wool, silk, jute, flax, bamboo or ramie, or one or more regenerated / synthetic fibres such as lyocell, viscose, modal, soya, polyester, acrylic, rayon, charcoal, linen, corn, milk fibre, PLA (poly lactic acid) fibre etc. Soluble yarns for manufacturing ply yarns (or for that matter ground yarns) may include any of polyvinyl alcohol (PVA), wool or a yarn product that is sold under the trade name "solucell".

[0097] It would be understood that the examples and embodiment discussed anywhere in the present specification are illustrative only. Those skilled in the art would immediately appreciate that various modifications in form and detail may be made without departing from or offending the spirit and scope of the invention as defined by the appended claims.
