Field of the Invention
[0001] The instant application is directed to a smoke filter for a smoking device having
an element that enhances the smoke flowing thereover.
Background of the Invention
[0002] The World Health Organization (WHO) has set forth recommendations for the reduction
of certain components of tobacco smoke in
WHO Technical Report Series No. 951, The Scientific Basis of Tobacco Product Regulation,
World Health Organization (2008). Therein, the WHO recommends that certain components, such as acetaldehyde, acrolein,
benzene, benzoapyrene, 1,3-butadiene, and formaldehyde, among others, be reduced to
a level below 125% of the median values of the data set. In view of new international
recommendations related to tobacco product regulation, there is a need for new tobacco
smoke filters and materials used to make tobacco smoke filters that are able to meet
these regulations.
[0003] The use of carbon loaded tobacco smoke filters for removing tobacco smoke components
is known. These filters include carbon-on-tow filters and carbon particulate contained
within chambers of the filter.
U.S. Patent No. 5,423,336 discloses a cigarette filter with a chamber loaded with activated carbon.
U.S. Publication No. 2010/0147317 discloses a cigarette filter with a spiral channel where activated carbon is adhered
to the channel's walls.
GB1,592,952 discloses a cigarette filter where a body of continuous filaments surrounds a core
of sorbent particles (
e.g., activated carbon) bonded together with a thermoplastic binder (
e.g., polyethylene and polypropylene).
WO 2008/142420 discloses a cigarette filter where the absorbent material (
e.g., activated carbon) is coated with a polymer material (
e.g., 0.4-5 wt % polyethylene).
WO 2009/112591 discloses a cigarette filter that produces little to no dust with a composite material
comprising at least one polymer (
e.g., polyethylene) and at least one other compound (
e.g., activated carbon).
[0004] Carbon block technology where activated carbon is formed into a monolithic porous
block with a binder is known. In
U.S. Patent Nos. 4,753,728,
6,770,736,
7,049,382,
7,160,453, and
7,112,280, carbon block technology, using low melt flow polymer binders, are principally used
as water filters.
[0005] Accordingly, there is a need for a porous mass having active particulates that can
be used in a smoke filter, the smoke filter having an encapsulated pressure drop that
is suitable for consumer use.

Detailed Description of the Invention
[0070] The porous mass described hereinafter may be used with a smoking device, such as
a tobacco smoking device. The porous mass includes active particles and non-fibrous
binder particles and may form a portion of a filter section of a smoking device. The
term "porous mass" as used herein refers to a mass comprising active particles and
nonfibrous binder particles that form a structure bound by the binder particles and
that includes void spaces therein, whereby smoke can travel through the porous mass
and interact with the active particles. In some embodiments, the structure may be
formed through the application of heat so that the binder particles soften to bind
to the active particles at various contact points. While reference is made herein
to "tobacco," it should be understood that the porous mass described herein is also
suitable for use with other substances that produce smoke when burned or heated (
i.e., smokeable substances).
[0071] It should be noted that when "about" is provided below in reference to a number,
the term "about" modifies each number of the numerical list. It should be noted that
in some numerical listings of ranges, some lower limits listed may be greater than
some upper limits listed. One skilled in the art will recognize that the selected
subset will require the selection of an upper limit in excess of the selected lower
limit.
[0072] Referring to Figures 1-4, there is shown several embodiments of a smoking device
(these are representative, but not limiting on the smoking devices contemplated hereinafter).
The term "smoking device," as used herein, most often refers to a cigarette, but it
is not so limited and could be used with other smoking devices, such as cigarette
holders, cigars, cigar holders, pipes, water pipes, hookahs, electronic smoking devices,
roll-your-own cigarettes or cigars, etc. Hereinafter, reference will be to a cigarette
as a generic term covering all of these smoking devices (unless otherwise specified).
[0073] In some embodiments, a smoking device may comprise a housing capable of maintaining
a smokeable substance in fluid contact with the filter. Suitable housings may include,
but are not limited to, a cigarette, a cigarette holder, a cigar, a cigar holder,
a pipe, a water pipe, a hookah, an electronic smoking device, a roll-your-own cigarette,
a roll-your-own cigar, and a paper.
[0074] In Figure 1, cigarette 10 includes a tobacco column 12 and a filter 14. Filter 14
may comprise at least two sections, first section 16 and second section 18. For example,
the first section 16 may comprise conventional filter material (discussed in greater
detail below) and the second section 18 comprises a porous mass (discussed in greater
detail below).
[0075] As used herein, the term "tobacco column" refers to the blend of tobacco, and optionally
other ingredients and flavorants that may be combined to produce a tobacco-based smokeable
article, such as a cigarette or cigar. In some embodiments, the tobacco column may
comprise ingredients selected from the group consisting of: tobacco, sugar (such as
sucrose, brown sugar, invert sugar, or high fructose corn syrup), propylene glycol,
glycerol, cocoa, cocoa products, a carob bean gum, carob bean extracts, and any combination
thereof. In still other embodiments, the tobacco column may further comprise flavorants,
menthol, licorice extract, diammonium phosphate, ammonium hydroxide, and any combination
thereof. Examples of suitable types of tobacco that may be used in the tobacco columns
may include, but are not limited to, bright leaf tobacco, burley tobacco, Oriental
tobacco (also known as Turkish tobacco), Cavendish tobacco, corojo tobacco, criollo
tobacco, Perique tobacco, shade tobacco, white burley tobacco, and any combination
thereof. The tobacco may be grown in the United States, or may be grown in a jurisdiction
outside the United States.
[0076] In Figure 2, cigarette 20 has a tobacco column 12 and filter 22. Filter 22 is multi-segmented
with three sections. In this embodiment, conventional filter materials 24 (or other
alternative filter sections) may flank the porous mass 26.
[0077] In Figure 3, cigarette 30 has a tobacco column 12 and a filter 32. Filter 32 is multi-segmented
with four sections. In this embodiment, end section 34 is a conventional material,
but sections 36, 37, and 38 may be any combination of other filter materials and porous
mass (so long as at least one of those sections is a porous mass of the present invention).
[0078] The foregoing embodiments are representative and not limiting. The inventive filters
may have any number of sections, for example, 2, 3, 4, 5, 6, or more sections, and
the sections may be placed in any suitable configuration. It is preferred that at
least one of the filter sections comprise a porous mass of the present invention.
Moreover, the sections may be the same as one another or different from one another.
[0079] Examples of sections that may incorporated with the porous masses of the present
invention to form filters may include, but are not limited to, sections that comprise
at least one element selected from the following: cellulose acetate, polypropylene,
polyethylene, polyolefin tow, polypropylene tow, polyethylene terephthalate, polybutylene
terephthalate, random oriented acetate, papers, corrugated papers, concentric filters
(e.g., a peripheral filter of fibrous tow and a core of a web material), carbon-on-tow
(sometimes referred to as a "Dalmatian filter"), silica, magnesium silicate, zeolites,
molecular sieves, metallocenes, salts, catalysts, sodium chloride, nylon, flavorants,
tobacco, capsules, cellulose, cellulosic derivatives, catalytic converters, iodine
pentoxide, coarse powders, carbon particles, carbon fibers, fibers, glass beads, nanoparticles,
void chambers (
e.g., formed by rigid elements, such as paper or plastic), baffled void chambers, and
any combination thereof. If a zeolite is used, examples of suitable zeolites include,
but are not limited to, BETA, SBA-15, MCM-41, MCM-48 modified by 3-aminopropylsilyl
groups, and any combination thereof. In some embodiments, the filter may be substantially
degradable over time (
e.g., over about 2 to about 5 years), either naturally or in the presence of a catalyst,
that in some embodiments, may be present in a filter section itself. Also included
are fibrous tows and papers with active materials (adhered thereto or impregnated
therein or otherwise incorporated therewith). Such active materials include activated
carbon (or charcoal), ion exchange resins, zeolites, desiccants, catalysts, or other
materials adapted to affect the tobacco smoke. If used, void chambers may be filled
(or partially filled) with active ingredients or materials incorporating the active
ingredients. Such active ingredients include activated carbon (or charcoal), ion exchange
resins, desiccants, or other materials adapted to affect the tobacco smoke. Additionally,
the section may be a porous mass of binder particles (
i.e., binder particles alone without any active particles). For example, this porous
mass without active particles may be made with thermoplastic particles (such as polyolefin
powders, including the binder particles discussed below) that are bonded or molded
together into a porous cylindrical shape.
[0080] In another embodiment, a section may comprise a space that defines a cavity between
two filter sections (one section including a porous mass of the present invention).
The cavity may be filled with granulated carbon, for example, or a flavorant, as another
example. The cavity may contain a capsule,
e.g., a polymeric capsule, that itself contains a flavorant or catalyst. The cavity,
in some embodiments, may also contain a molecular sieve that reacts with selected
components in the smoke to remove or reduce the concentration of the components without
adversely affecting desirable flavor constituents of the smoke. In an embodiment,
the cavity may include tobacco as an additional flavorant. One should note that if
the cavity is insufficiently filled with a chosen substance, in some embodiments,
this may create a lack of interaction between the components of the mainstream smoke
and the substance in the cavity and in the other filter section(s).
[0081] Flavorants that may be suitable for use in the present invention include any flavorant
suitable for use in smoking devices including those that to impart a taste and/or
a flavor to the smoke stream. The flavorants may include, but not be limited to, organic
material (or naturally flavored particles), carriers for natural flavors, carriers
for artificial flavors, and any combination thereof. Organic materials (or naturally
flavored particles) include, but are not limited to, tobacco, cloves (
e.g., ground cloves and clove flowers), cocoa, and the like. Natural and artificial flavors
may include, but are not limited to, menthol, cloves, cherry, chocolate, orange, mint,
mango, vanilla, cinnamon, tobacco, and the like. Such flavors may be provided by menthol,
anethole (licorice), limonene (citrus), eugenol (clove), and the like. In some embodiments,
more than one flavorant may be used including any combination of the flavorants provided
herein. These flavorants may be placed in the tobacco column or in a section of a
filter. Additionally, in some embodiments, the porous masses of the present invention
may comprise a flavorant. The amount to include will depend on the desired level of
flavor in the smoke taking into account all filter sections, the length of the smoking
device, the type of smoking device, the diameter of the smoking device, as well as
other factors known to those of skill in the art.
[0082] The sections that comprise a filter may be wrapped with paper to form filter rods.
The term "paper" as used herein refers collectively to any wrapping papers that are
used in the production of smoking devices, including tipping paper, plug wrap paper,
tipping base paper, and the like. Suitable papers for use in conjunction with present
invention include wood-based papers, papers containing flax, flax papers, functionalized
papers (e.g., those that are functionalized so as to reduce tar and/or carbon monoxide),
special marking papers, colorized papers, and any combination thereof. In some embodiments,
the papers may be high porosity, corrugated, and/or have a high surface strength.
In some embodiments, the papers may comprise additives, sizing, and/or printability
agents. In some embodiments, the filter rods that comprise a porous mass of the present
invention may have lengths ranging from about 80 mm to about 150 mm. During processing,
the filter rods may be subsequently split into about 4 or about 6 individual segments
of about 5 to about 35 mm in length during a smoking device tipping operation. For
dual or triple filters, the filters may be first cut into segments and combined with
paper and/or charcoal segments prior to tipping. The filter rods may be attached to
tobacco column with paper or other smoking apparatus to produce a finished smoking
device. By way of example, in traditional cigarette manufacturing, at least three
papers are used: plug wrap, cigarette paper, and tipping paper. Plug wrap refers to
the paper that is used to cover the filter section of the cigarette as that filter
is produced and before it is joined to a tobacco column. Cigarette paper refers to
the paper that is used to cover the tobacco column section of the cigarette as that
tobacco column is produced and before it is joined to a filter section. Finally, tipping
paper refers to the paper that is used to cover the filter section and a portion of
the tobacco column as the two sections are joined to form a cigarette. The seams of
the various papers used to form a cigarette are joined using at least one adhesive,
and more than one type of adhesive may be used in the formation of the cigarette.
By way of example, as a traditional cellulose acetate filter section is formed, a
polyvinyl alcohol adhesive may be used to anchor the filter to the paper and a hot
melt glue may be used at the edge of the paper to keep the filter wrapped. Also, cigarette
paper may use a starch adhesive to join the edges of the paper. Finally tipping paper
may be more fully coated, that is coated over most of the surface rather than only
at the seam area, with a hot melt adhesive to ensure that the filter section and the
tobacco section remain properly joined. In some cigarette products, ventilation holes
are made through the tipping paper, or through both the tipping paper and the plug
wrap in order to allow air to be drawn into the smoke stream.
[0083] In some embodiments, the filters may have a diameter in the range of about 5 mm to
about 10 mm and a length of from about 5 mm to about 35 mm. In some embodiments, for
example for ultra-slim or super-slim cigarettes, the filters may have a diameter in
the range of less than 5 mm, for example, 3 mm or less, including, but not limited
to, a lower diameter limit of 0.5 mm. For cigar embodiments, the filters may have
a diameter larger than 20 mm, for example about 30 mm, as desired. Similarly, the
size of the filter for other smoking devices may vary based on the intended use and
consumer demand (
e.g., in a pipe).
[0084] In Figure 4, a pipe 40 has a burning bowl 42, a mouth piece 44, and a channel 46
interconnecting burning bowl 42 and mouth piece 44. Channel 46 includes a cavity 47.
Cavity 47 is adapted for receipt of a filter 48. Filter 48 may be a multi-segmented
filter as discussed above or may consist solely of the porous mass. The size of the
filter may vary based on the dimensions of cavity 47. In some embodiments, filter
48 may be removable, replaceable, disposable, recyclable, and/or degradable.
[0085] In the foregoing embodiments, the conventional materials and porous mass are "joined."
The term "joined," as used herein, means that the porous mass is in-line (or in series)
neighboring a tobacco column or another filter section, so that when the cigarette
is smoked, smoke from the tobacco column must pass through (
e.g., in series) the porous mass to arrive at its intended recipient (
e.g., a smoker). As noted above, the porous mass may be joined to the tobacco column
through paper wrapping techniques,
e.g., using paper and/or an adhesive. Additionally, in some embodiments, the porous mass
may be joined to the tobacco column using an adhesive, which preferably is free from
components that, upon burning, would interfere with the purposes of the invention.
[0086] As shown in Figures 1-3, in some embodiments, a filter section comprising a porous
mass and at least one other filter section may be co-axial, juxtaposed, abutting,
and have equivalent cross-sectional areas (or substantially equivalent cross-sectional
areas). But, it is understood that the porous mass and the conventional materials
need not be joined in such a fashion, and that there may be other possible configurations.
Moreover, while, it is envisioned that porous mass will be, most often, used in a
combined or multi-segmented cigarette filter configuration, as shown in Figures 1-3;
the invention is not so limited and a smoking device may comprise only a porous mass
of the present invention, as discussed above with regard to Figure 4. Further, although
in some embodiments, the porous mass will be juxtaposed to the tobacco column, as
shown in Figure 1, the present disclosure is not so limited. For example, a porous
mass of the present invention may be separated from the tobacco by a hollow cavity
(
e.g., a tube, or channel, such as in a pipe or hookah or a cigarette or cigar holder),
for example, see Figure 4. In other embodiments, a porous mass of the present invention
may be separated from a tobacco column by a bendable element, allowing a consumer
to shape the smoking device.
[0087] In some embodiments, the porous masses of the present invention comprise active particles
that are at least partially bonded together with binder particles. For example, see
Figure 5, a photomicrograph of an embodiment of the porous mass where active particles
(
e.g., activated carbon particles) 50 and binder particles 52. Shown at 54 is an example
of a point of contact. Note: in this embodiment (Figure 5), binder particles and active
particles are joined at points of contact, the points of contact are randomly distributed
throughout the porous mass, and the binder particles have retained their original
physical shape (or substantially retained their original shape,
e.g., no more that 10% variation (
e.g., shrinkage) in shape from original). (The active particles and the binder particles
are discussed in greater detail below.) Although not wishing to be limited to any
theory, it is believed that the points of contact form when the binder particles are
heated to their softening temperature, but not hot enough to reach a true melt. In
some embodiments, it is believed that the porous masses of the present invention are
constructed so that they exhibit a minimal encapsulated pressure drop (defined below)
while maximizing the active particles' surface area.
[0088] There may be any weight ratio of active particles to binder particles in the porous
mass. In some embodiments, the ratio may be about 1 to about 99 weight % active particles
and about 99 to about 1 weight % binder particles. In some embodiments, the ratio
may be about 25 to about 99 weight % active particles and about 1 to about 75 weight
% binder particles. In some embodiments, the ratio may be about 40 to about 99 weight
% active particles and about 1 to about 60 weight % binder particles. In one embodiment
of the porous mass, the active particles comprise about 50 to about 99 weight % of
the mass while the binder particles comprise about 1 to about 50 weight % of the mass.
In another embodiment, the active particles comprise about 60 to about 95 weight %
of the mass while the binder particles comprise about 5 to about 40 weight % of the
mass. Moreover, in yet another embodiment, the active particles comprise about 75
to about 90 weight % of the mass while the binder particles comprise about 10 to about
25 weight % of the mass.
[0089] In one embodiment of the porous mass, the porous mass has a void volume in the range
of about 40% to about 90%. In another embodiment, it has a void volume of about 60%
to about 90%. In yet another embodiment, it has a void volume of about 60% to about
85%. Void volume is the free space left after accounting for the space taken by the
active particles.
[0090] To determine void volume, although not wishing to be limited by any particular theory,
it is believed that testing indicates that the final density of the mixture was driven
almost entirely by the active particle; thus the space occupied by the binder particles
was not considered for this calculation. Thus, void volume, in this context, is calculated
based on the space remaining after accounting for the active particles. To determine
void volume, first the upper and lower diameters based on the mesh size were averaged
for the active particles, and then the volume was calculated (assuming a spherical
shape based on that averaged diameter) and using the density of the active material.
Then, the percentage void volume is calculated as follows:

[0091] In one embodiment, the porous mass has an encapsulated pressure drop (EPD) in the
range of about 0.10 to about 25 mm of water per mm length of porous mass. As used
herein, the term "encapsulated pressure drop" refers to the static pressure difference
between the two ends of a specimen when it is traversed by an air flow under steady
conditions when the volume flow is 17.5 ml/sec at the output end when the specimen
is completely encapsulated in a measuring device so that no air can pass through the
wrapping. EPD has been measured herein under the CORESTA ("Cooperation Centre for
Scientific Research Relative to Tobacco") Recommended Method No. 41, dated June 2007.
In another embodiment, a porous mass of the present invention may have an EPD in the
range of about 0.10 to about 10 mm of water per mm length of porous mass. In other
embodiments, a porous mass of the present invention may have an EPD of about 2 to
about 7 mm of water per mm length of porous mass (or no greater than 7 mm of water
per mm length of porous mass). To obtain the desired EPD, the active particles must
have a greater particle size than the binder particles. In one embodiment, the ratio
of binder particle size to active particle size is in the range of about 1:1.5 to
about 1:4.
[0092] In some embodiments, the porous mass of the present invention may have an active
particle loading of at least about 1 mg/mm, 2 mg/mm, 3 mg/mm, 4 mg/mm, 5 mg/mm, 6
mg/mm, 7 mg/mm, 8 mg/mm, 9 mg/mm, 10 mg/mm, 11 mg/mm, 12 mg/mm, 13 mg/mm, 14 mg/mm,
15 mg/mm, 16 mg/mm, 17 mg/mm, 18 mg/mm, 19 mg/mm, 20 mg/mm, 21 mg/mm, 22 mg/mm, 23
mg/mm, 24 mg/mm, or 25 mg/mm in combination with an EPD of less than about 20 mm of
water or less per mm of porous mass, 19 mm of water or less per mm of porous mass,
18 mm of water or less per mm of porous mass, 17 mm of water or less per mm of porous
mass, 16 mm of water or less per mm of porous mass, 15 mm of water or less per mm
of porous mass, 14 mm of water or less per mm of porous mass, 13 mm of water or less
per mm of porous mass, 12 mm of water or less per mm of porous mass, 11 mm of water
or less per mm of porous mass, 10 mm of water or less per mm of porous mass, 9 mm
of water or less per mm of porous mass, 8 mm of water or less per mm of porous mass,
7 mm of water or less per mm of porous mass, 6 mm of water or less per mm of porous
mass, 5 mm of water or less per mm of porous mass, 4 mm of water or less per mm of
porous mass, 3 mm of water or less per mm of porous mass, 2 mm of water or less per
mm of porous mass, or 1 mm of water or less per mm of porous mass. By way of example,
in some embodiments, the porous mass may have an active particle loading of at least
about 1 mg/mm and an EPD of about 20 mm of water or less per mm of porous mass. In
other embodiments, the porous mass may have an active particle loading of at least
about 1 mg/mm and an EPD of about 20 mm of water or less per mm of porous mass, wherein
the active particle is not carbon. In other embodiments, the porous mass may have
an active particle comprising carbon with a loading of at least 6 mg/mm in combination
with an EPD of 10 mm of water or less per mm of porous mass.
[0093] Depending on how the porous mass is made, the porous mass may have any desired length.
In a batch molding process, for example, the length would likely match the dimension
of the mold(s) used. Additionally, in a continuous production process, the porous
mass may be one long continuous cylinder of any desired length. In either event, the
porous mass could subsequently be cut into desired smaller lengths or sections. The
desired length may depend on the particular application in which the porous mass may
be used. In one embodiment, the porous mass may have a length of about 1 mm to about
35 mm. In another embodiment, the porous mass may have a length of about 2 mm to about
30 mm. In another, the porous mass may have a length of about 7 mm to about 20 mm.
[0094] The porous mass may have any physical shape. The porous mass may have a helical shape,
a triangular shape, a disk shape, or a square shape, in some embodiments. In one embodiment,
it is in the shape of a cylinder. A hybrid shape of these shapes may be suitable as
well. In some embodiments, the porous mass may be machined to be lighter in weight,
if desired, for example, by drilling out a portion of the porous mass. In one embodiment,
the porous mass may have a specific shape for a cigarette holder or pipe that is adapted
to fit within the cigarette holder or pipe to allow for smoke passage through the
filter to the consumer. When discussing the shape of a porous mass herein, with respect
to a traditional smoking device filter, the shape may be referred to in terms of diameter
or circumference (wherein the circumference is the perimeter of a circle) of the cross
section of the cylinder. But in embodiments where a porous mass of the present invention
is in a shape other than a true cylinder, it should be understood that the term "perimeter"
is used to mean the perimeter of any shaped cross-section, including a circular cross-section.
[0095] The active particles may be any material adapted to enhance smoke flowing thereover.
Adapted to enhance smoke flowing thereover refers to any material that can remove,
reduce, or add components to a smoke stream. The removal or reduction (or addition)
may be selective. By way of example, in the smoke stream from a cigarette, compounds
such as those shown below in the following listing may be selectively removed or reduced.
This table is available from the U.S. FDA as a Draft Proposed Initial List of Harmful/Potentially
Harmful Constituents in Tobacco Products, including Tobacco Smoke; any abbreviations
in the below listing are well-known chemicals in the art. In some embodiments, the
active particle may reduce or remove at least one component selected from the listing
of components in smoke below, including any combination thereof.

[0096] One example of an active material is activated carbon (or activated charcoal or active
coal). The activated carbon may be low activity (about 50% to about 75% CCl
4 adsorption) or high activity (about 75% to about 95% CCl
4 adsorption) or a combination of both. In some embodiments, the active carbon may
be nano-scaled carbon particle, such as carbon nanotubes of any number of walls, carbon
nanohorns, bamboo-like carbon nanostructures, fullerenes and fullerene aggregates,
and graphene including few layer graphene and oxidized graphene. Other examples of
such materials include ion exchange resins, desiccants, silicates, molecular sieves,
metallocenes, silica gels, metallocene, activated alumina, zeolites, perlite, sepiolite,
Fuller's Earth, magnesium silicate, metal oxides (e.g., iron oxide and iron oxide
nanoparticles like about 12 nm Fe
3O
4), nanoparticles (e.g., metal nanoparticles like gold and silver; metal oxide nanoparticles
like alumina; magnetic, paramagnetic, and superparamagentic nanoparticles like gadolinium
oxide, various crystal structures of iron oxide like hematite and magnetite, gado-nanotubes,
and endofullerenes like Gd@C
60; and core-shell and onionated nanoparticles like gold and silver nanoshells, onionated
iron oxide, and others nanoparticles or microparticles with an outer shell of any
of said materials) and any combination of the foregoing (including activated carbon).
It should be noted that nanoparticles include nanorods, nanospheres, nanorices, nanowires,
nanostars (like nanotripods and nanotetrapods), hollow nanostructures, hybrid nanostructures
that are two or more nanoparticles connected as one, and non-nano particles with nano-coatings
or nano-thick walls. It should be further noted that nanoparticles include the functionalized
derivatives of nanoparticles including, but not limited to, nanoparticles that have
been functionalized covalently and/or non-covalently, e.g., pi-stacking, physisorption,
ionic association, van der Waals association, and the like. Suitable functional groups
may include, but not be limited to, moieties comprising amines (1°, 2°, or 3°), amides,
carboxylic acids, aldehydes, ketones, ethers, esters, peroxides, silyls, organosilanes,
hydrocarbons, aromatic hydrocarbons, and any combination thereof; polymers; chelating
agents like ethylenediamine tetraacetate, diethylenetriaminepentaacetic acid, triglycollamic
acid, and a structure comprising a pyrrole ring; and any combination thereof. Functional
groups may enhance removal of smoke components and/or enhance incorporation of nanoparticles
into a porous mass. Ion exchange resins include, for example, a polymer with a backbone,
such as styrene-divinyl benzene (DVB) copolymer, acrylates, methacrylates, phenol
formaldehyde condensates, and epichlorohydrin amine condensates; and a plurality of
electrically charged functional groups attached to the polymer backbone. In some embodiments,
the active particles are a combination of various active particles. In some embodiments,
the porous mass may comprise multiple active particles. In some embodiments, an active
particle may comprise at least one element selected from the group of active particles
disclosed herein. It should be noted that "element" is being used as a general term
to describe items in a list. In some embodiments, the active particles are combined
with at least one flavorant.
[0097] In some embodiments, a mixture of active particles may be used to remove multiple
harmful substances from a smoke stream. For example, while activated charcoal has
been shown to be successful in removing substances such as formaldehyde and acetone
from cigarette smoke, it is ineffective in removing carbon monoxide. However, carbon
monoxide may be removed from a gaseous stream by exposure to iodine pentoxide, a molecular
sieve (such as a metallocene), a molecular oxide, a metal catalyst (such as palladium),
and the like.
[0098] In one embodiment, the active particles have a particle sizes ranging from particles
having at least one dimension of about less than one nanometer, such as graphene,
to as large as a particle having a diameter of about 5000 microns. The active particles
may range from a lower size limit in at least one dimension of about: 0.1 nanometers,
0.5 nanometers, 1 nanometer, 10 nanometers, 100 nanometers, 500 nanometers, 1 micron,
5 microns, 10 microns, 50 microns, 100 microns, 150 microns, 200 microns, and 250
microns. The active particles may range from an upper size limit in at least one dimension
of about: 5000 microns, 2000 microns, 1000 microns, 900 microns, 700 microns, 500
microns, 400 microns, 300 microns, 250 microns, 200 microns, 150 microns, 100 microns,
50 microns, 10 microns, and 500 nanometers. Any combination of lower limits and upper
limits above may be suitable for use in the present invention, wherein the selected
maximum size is greater than the selected minimum size. In some embodiments, the active
particles may be a mixture of particle sizes ranging from the above lower and upper
limits.
[0099] The binder particles may be any suitable thermoplastic binder particles. In one embodiment,
the binder particles exhibit virtually no flow at its melting temperature. This means
a material that when heated to its melting temperature exhibits little to no polymer
flow. Materials meeting these criteria include, but are not limited to, ultrahigh
molecular weight polyethylene, very high molecular weight polyethylene, high molecular
weight polyethylene, and combinations thereof. In one embodiment, the binder particles
have a melt flow index (MFI, ASTM D1238) of less than or equal to about 3.5 g/10min
at 190°C and 15 Kg (or about 0-3.5 g/10min at 190°C and 15 Kg). In another embodiment,
the binder particles have a melt flow index (MFI) of less than or equal to about 2.0
g/10min at 190°C and 15 Kg (or about 0-2.0 g/10min at 190°C and 15 Kg). One example
of such a material is ultra high molecular weight polyethylene, UHMWPE (which has
no polymer flow, MFI of about 0, at 190°C and 15 Kg, or an MFI of about 0-1.0 at 190°C
and 15 Kg); another material may be very high molecular weight polyethylene, VHMWPE
(which may have MFIs in the range of, for example, about 1.0-2.0 g/10min at 190°C
and 15 Kg); or high molecular weight polyethylene, HMWPE (which may have MFIs of,
for example, about 2.0-3.5 g/10min at 190°C and 15 Kg). In some embodiments, it may
be preferable to use a mixture of binder particles having different molecular weights
and/or different melt flow indexes.
[0100] In terms of molecular weight, "ultra-high molecular weight polyethylene" as used
herein refers to polyethylene compositions with weight-average molecular weight of
at least about 3 x 10
6 g/mol. In some embodiments, the molecular weight of the ultra-high molecular weight
polyethylene composition is between about 3 x 10
6 g/mol and about 30 x 10
6 g/mol, or between about 3 x 10
6 g/mol and about 20 x 10
6 g/mol, or between about 3 x 10
6 g/mol and about 10 x 10
6 g/mol, or between about 3 x 10
6 g/mol and about 6 x 10
6 g/mol. "Very-high molecular weight polyethylene" refers to polyethylene compositions
with a weight average molecular weight of less than about 3 x 10
6 g/mol and more than about 1 x 10
6 g/mol. In some embodiments, the molecular weight of the very-high molecular weight
polyethylene composition is between about 2 x 10
6 g/mol and less than about 3 x 10
6 g/mol. "High molecular weight polyethylene" refers to polyethylene compositions with
weight-average molecular weight of at least about 3 x 10
5 g/mol to 1 x 10
6 g/mol. For purposes of the present specification, the molecular weights referenced
herein are determined in accordance with the Margolies equation ("Margolies molecular
weight").
[0101] Suitable polyethylene materials are commercially available from several sources including
GUR® UHMWPE from Ticona Polymers LLC, a division of Celanese Corporation of Dallas,
TX, and DSM (Netherland), Braskem (Brazil), Beijing Factory No. 2 (BAAF), Shanghai
Chemical, and Qilu (People's Republic of China), Mitsui and Asahi (Japan). Specifically,

in the range of about 5 dl/g to about 30 dl/g and a degree of crystallinity of about
80% or more as described in

in the range of about 300,000 g/mol to about 2,000,000 g/mol as determined by ASTM-D
4020, an average particle size, D
50, between about 300 µm and about 1500 µm, and a bulk density between about 0.25 g/ml
and about 0.5 g/ml as described in
U.S. Provisional Application No. 61/330,535 filed May 3, 2010.
[0103] The binder particles may assume any shape. Such shapes include spherical, hyperion,
asteroidal, chrondular, or interplanetary dust-like, granulated, potato, irregular,
or combinations thereof. In preferred embodiments, the binder particles suitable for
use in the present invention are non-fibrous. In some embodiments the binder particles
are in the form of a powder, pellet, or particulate. In some embodiments, the binder
particles are a combination of various binder particles.
[0104] In some embodiments, the binder particles may range from a lower size limit in at
least one dimension of about: 0.1 nanometers, 0.5 nanometers, 1 nanometer, 10 nanometers,
100 nanometers, 500 nanometers, 1 micron, 5 microns, 10 microns, 50 microns, 100 microns,
150 microns, 200 microns, and 250 microns. The binder particles may range from an
upper size limit in at least one dimension of about: 5000 microns, 2000 microns, 1000
microns, 900 microns, 700 microns, 500 microns, 400 microns, 300 microns, 250 microns,
200 microns, 150 microns, 100 microns, 50 microns, 10 microns, and 500 nanometers.
Any combination of lower limits and upper limits above may be suitable for use in
the present invention, wherein the selected maximum size is greater than the selected
minimum size. In some embodiments, the binder particles may be a mixture of particle
sizes ranging from the above lower and upper limits.
[0105] Additionally, the binder particles may have a bulk density in the range of about
0.10 g/cm

3. In yet another embodiment, the bulk density may be in the range of about 0.20 g/cm
3 to about 0.47 g/cm
3.
[0106] In addition to the foregoing binder particles, other conventional thermoplastics
may be used as binder particles. Such thermoplastics include, but are not limited
to, polyolefins, polyesters, polyamides (or nylons), polyacrylics, polystyrenes, polyvinyls,
polytetrafluoroethylene (PTFE), polyether ether ketone (PEEK), any copolymer thereof,
any derivative thereof, and any combination thereof. Non-fibrous plasticized cellulose
derivatives may also be suitable for use as binder particles in the present invention.
Examples of suitable polyolefins include, but are not limited to, polyethylene, polypropylene,
polybutylene, polymethylpentene, any copolymer thereof, any derivative thereof, any
combination thereof and the like. Examples of suitable polyethylenes further include
low-density polyethylene, linear low-density polyethylene, high-density polyethylene,

thereof, any derivative thereof, any combination thereof and the like. Examples of
suitable polyacrylics include, but are not limited to, polymethyl methacrylate, any

suitable polyvinyls include, but are not limited to, ethylene vinyl acetate, ethylene

any copolymer, any derivative, and any combination of the above listed binders.
[0107] The porous mass is effective at the removal of components from smoke, for example,
those in the listing above. A porous mass can be used to reduce the delivery of certain
tobacco smoke components targeted by the WHO. For example, a porous mass where activated
carbon is used as the active particles can be used to reduce the delivery of certain
tobacco smoke components to levels below the WHO recommendations. (See Table 13, below.)
In one embodiment, the porous mass, where activated carbon is used, has a length in
the range of about 4 mm to about 11 mm. The components include: acetaldehyde, acrolein,
benzene, benzo[a]pyrene, 1,3-butadiene, and formaldehyde. The porous mass with activated
carbon may reduce acetaldehydes in a smoke stream by about 3.0% to about 6.5%/mm length
of porous mass; acrolein in a smoke stream by about 7.5% to about 12%/mm length of
porous mass; benzene in a smoke stream by about 5.5% to about 8.0%/mm length of porous
mass; benzo[a]pyrene in a smoke stream by about 9.0% to about 21.0%/mm length of porous
mass; 1,3-butadiene in a smoke stream by about 1.5% to about 3.5%/mm length of porous
mass; and formaldehyde in a smoke stream by about 9.0% to about 11.0%/mm length of
porous mass. In another example, a porous mass where an ion exchange resin is used
as the active particles can be used to reduce the delivery of certain tobacco smoke
components to below the WHO recommendations. See Table 14, below. In one embodiment,
the porous mass, where ion exchange resins are used, has a length in the range of
about 7 mm to about 1 mm. The components include: acetaldehyde, acrolein, and formaldehyde.
In some embodiments, a porous mass of the present invention having an ion exchange
resin may reduce: acetaldehydes in a smoke stream by about 5.0% to about 7.0%/mm length
of porous mass; acrolein in a smoke stream by about 4.0% to about 6.5%/mm length of
porous mass; and formaldehyde in a smoke stream by about 9.0% to about 11.0%/mm length
of porous mass.
[0108] The porous mass may be made by any suitable means. In some embodiments, this may
be a batch process. In others, this may be a continuous process.
[0109] In one embodiment of a suitable method, the active particles and binder particles
are blended together and introduced into a mold. The mold is heated to a temperature
at or above the melting point of the binder particles, e.g., in one embodiment about
150°C to 300°C and held at the temperature for a period of time sufficient to heat
the mold and its contents to the desired temperature. Thereafter, the mass is removed
from the mold and cooled to room temperature. These methods may be done in small batches
or large batches that may be suitable for commercial production.
[0110] In some embodiments, a suitable process may be a free sintering process, because
the binder particles do not flow (or flow very little) at the sintering temperature
and no pressure is applied to the blended materials in the mold. In this embodiment,
point bonds are formed between the active particles and the binder particles. This
is believed to enable the formation of superior bonding and maximizing the interstitial
space, while minimizing the blinding of the surface of the active particles by free
flowing molten binder. Also see,
U.S. Patents 6,770,736,
7,049,382, and
7,160,453, incorporated herein by reference.
[0111] Alternatively, a porous mass of the present invention may be made by a process involving
sintering under pressure. As the mixture of the active particles and the binder particles
are heated (or at a temperature which may be below, at, or above the melting temperature
of the binder particles) a pressure is exerted on the mixture to facilitate coalescence
of the porous mass.
[0112] Also, in some embodiments, the porous mass may be made by an extrusion sintering
process where the mixture is heated in an extruder barrel and extruded into the porous
mass.
[0113] Any suitable method for forming a smoking device filter comprising a porous mass
of the present invention may be used in conjunction with the porous masses. For example,
in one embodiment, an apparatus for producing a smoking device filter may be used
that has at least a plurality of areas comprising: a container area comprising at
least a plurality of first filter section pieces; a second container area comprising
at least a plurality of second filter section pieces, the second filter section pieces
comprising a porous mass having an active particle and a binder particle, the porous
mass having: an active particle loading of at least about 1 mg/mm, an EPD of about
20 mm of water or less per mm of porous mass; a joiner area wherein a first filter
section piece and a second filter section piece are joined; a wrapping area wherein
the first filter section piece and the second filter section piece are wrapped with
a paper to form a smoking device filter; and a conveyor to transport the smoking device
filter to a subsequent area for storage or use. In some embodiments, a filter rod
may be formed in this process that comprises a plurality of filters that when cut
can be used to form multiple smoking devices (
e.g., 4 cigarettes per 1 filter rod).
[0114] In some embodiments, the smoking device filters may be directly transported to a
manufacturing line whereby they will be combined with tobacco columns to form smoking
devices. An example of such a method includes a process for producing a smoking device
comprising: providing a filter rod comprising at least one filter section comprising
a porous mass that comprises an active particle and a binder particle; providing a
tobacco column; cutting the filter rod transverse to its longitudinal axis through
the center of the rod to form at least two filters having at least one filter section,
each filter section comprising a porous mass that comprises an active particle and
a binder particle; and joining at least one of the filters to the tobacco column along
the longitudinal axis of the filter and the longitudinal axis of the tobacco column
to form at least one smoking device.
[0115] In traditional cigarette manufacturing, the machines that join the filter section
to the tobacco column, as well as the machines that join together the section of the
multi-component filter, tend to compress the sections of the cigarette as they progress
through the joining process. In some embodiments, the porous mass of the present invention
may be non-compressible or less compressible than a traditional cellulose acetate
filter section, which may lead to difficulty in some manufacturing processes. In embodiments
where ultra high molecular weight polymers, such as ultra high molecular weight polyethylene,
are used the porous mass of the present invention tends to be incompressible. In such
cases, it may be desirable to wrap or encase the porous mass section with a material
that is compressible. The wrapping or encasing material is placed along the longitudinal
axis of the porous mass filter section such that the wrapping or encasing material
is between the porous mass and the plug wrap paper. The wrapping or encasing material
should be selected such that it provides the desired compressibility while also exhibiting
a relatively high pressure drop such that smoke drawn through the section preferentially
travels through the porous mass rather than the wrapping or encasing material or encasing
material is greater than the encapsulated pressure drop of the porous mass. In some
embodiments, the wrapping material may have an encapsulated pressure drop that is
1% higher than the encapsulated pressure drop of the porous mass, in other embodiments
the difference may be 5% higher, 10% higher, 25% higher, 50% higher, 75% higher, 100%
higher, 125% higher, 150% higher, 175% higher, 200% higher, 225% higher, 250% higher,
275% higher, or 300% higher. One of skill in the art will recognize that the difference
in the encapsulated pressure drop between the wrapping or encasing material and the
porous mass may go even higher so long as the user is not negatively effected and
so long as the wrapping or encasing material continues to provide the desired compressibility.
In some embodiments, the wrapping or encasing material may comprise cellulose acetate,
polypropylene, polyethylene, polyolefin tow, polypropylene tow, polyethylene terephthalate,
polybutylene terephthalate, random oriented acetate, paper, corrugated paper, carbon-on-tow,
silica, magnesium silicate, nylon, cellulose, and any combination thereof. IN other
embodiments, the wrapping or encasing material is placed along the longitudinal axis
of the porous mass filter section such that the wrapping or encasing material is on
the outside of the plug wrap paper. One skilled will recognize that the porous mass
diameter must be selected to compensate for the diameter increase as layer of papers
or wrappings or encasing materials are added. The final filter diameter must match
the tobacco column diameter for the filter/tobacco column combine step. In other embodiments,
the wrapping or encasing material is placed along the longitudinal axis of the porous
mass filter section such that the wrapping or encasing material is in direct contact
with the porous mass. This configuration can eliminate paper use in the sintering
process. In other embodiments, the smoking device filters may be placed in a suitable
container for storage until further use. Suitable storage containers include those
commonly used in the smoking device filter art including, but not limited to crates
boxes, drums, bags, cartons, and the like. Storage and transportation containers used
with the porous mass filter sections of the present invention may need to be altered
to account for presence of the porous mass. By way of example, cylindrical and other
shaped rods or cigarettes incorporating porous mass filter sections of the present
invention may be heavier in weight, or more brittle than a cellulose acetate filter
section. In addition, due to the active nature of the porous mass, it may be desirable
to ship porous mass sections or cigarettes incorporating porous mass sections such
that the porous mass is not exposed to environmental contamination.
[0116] In some embodiments, a method of making a filter may comprise: providing a blend
comprising active particles and binder particles; placing the blend in a mold; heating
the blend in the mold to a temperature at or above the melting point of the binder
particles so as to form a porous mass selected from at least one porous mass of the
present invention; removing the porous mass from the mold; and forming a filter comprising
the porous mass.
[0117] In some embodiments, a method of making a smoking device filter may comprise: providing
a blend comprising an active particle and a binder particle; heating the blend; extruding
the blend while at an elevated temperature so as to form a porous mass selected from
at least one porous mass of the present invention; and forming a filter comprising
the porous mass.
[0118] In some embodiments, a method for producing a smoking device may comprise: providing
a first filter section; providing at least one second filter section, wherein the
second filter section comprises a porous mass selected from at least one porous mass
of the present invention; joining the first filter section and at least one second
filter section so as to form a filter rod; and joining at least a portion of the filter
rod with a tobacco column to form a smoking device.
[0119] In some embodiments, a method of making a filter rod may comprise: providing a container
that comprises at least a plurality of first filter section pieces; providing a second
container comprising at least a plurality of second filter section pieces, wherein
the second filter section pieces comprise a porous mass selected from at least one
porous mass of the present invention; joining a first filter section piece and a second
filter section piece end-to-end along the longitudinal axis of the first filter section
piece and the second filter section piece to form an unwrapped filter rod; wrapping
the first filter section piece and the second filter section piece with a paper to
form a filter rod; and transporting the filter rod to a subsequent area for storage
or use.
[0120] In some embodiments, a method of making a smoking device may comprise: providing

Examples
[0191] In the following example, the effectiveness of a porous mass in removing certain
components of the cigarette smoke is illustrated. The porous mass was made from 25
weight % GUR 2105 from Ticona, of Dallas, TX and 75 weight % PICA RC 259 (95% active
carbon) from PICA USA, Inc. of Columbus, OH. The porous mass has a % void volume of
72% and an encapsulated pressure drop (EPD) of 2.2 mm of water/mm of porous mass length.
The porous mass has a circumference of about 24.5 mm. The PICA RC 259 carbon had an
average particle size of 569 microns (µ). The porous mass was made by mixing the resin
(GUR 2105) and carbon (PICA RC 259) and then filling a mold with the mixture without
pressure on the heated mixture (free sintering). Then, the mold was heated to 200°C
for 40 minutes. Thereafter, the porous mass was removed from the mold and allowed
to cool. A defined-length section of the porous mass was combined with a sufficient
amount of cellulose acetate tow to yield a filter with a total encapsulated pressure
drop of 70 mm of water. All smoke assays were performed according to tobacco industry
standards. All cigarettes were smoked using the Canadian intense protocol
(i.e., T-115, "Determination of "Tar," Nicotine and Carbon Monoxide in Mainstream Tobacco
Smoke," Health Canada, 1999) and a Cerulean 450 smoking machine.

[0193] In the following example, the effectiveness of a porous ion exchange resin mass in
removing certain components of the cigarette smoke is illustrated. The porous mass
was made from 20 weight % GUR 2105 from Ticona, of Dallas, TX and 80 weight % of an
amine based resin (AMBERLITE IRA96RF from Rohm & Haas of Philadelphia, PA). A 10 mm
section of the porous mass was combined with a sufficient amount of cellulose acetate
tow (12 mm) to yield a filter with a total encapsulated pressure drop of 70 mm of
water. All smoke assays were performed according to tobacco industry standards. All
cigarettes were smoked using the Canadian intense protocol
(i.e., T-115, "Determination of "Tar," Nicotine and Carbon Monoxide in Mainstream Tobacco
Smoke," Health Canada, 1999) and a Cerulean 450 smoking machine.

[0195] In the following example, a carbon-on-tow filter element is compared to the inventive
porous mass. In this comparison, equal total carbon loadings are compared. In other
words, the amount of carbon in each element is the same; the length of the element
is allowed to change so that equal amounts of carbon were obtained. The reported change
in smoke component is made in relation to conventional cellulose acetate filter (the
% change is in relation to a conventional cellulose acetate filter). All filter tips
consisted of the carbon element and cellulose acetate tow. All filter tips were tipped
with a sufficient length of cellulose acetate filter tow to obtain a targeted filter
pressure drop of 70 mm of water. The total filter length was 20 mm (carbon element
and tow element). The carbon was 30x70, 60% active PICA carbon. All cigarettes were
smoked using the Canadian intense protocol (i.e.,
T-115, "Determination of "Tar," Nicotine and Carbon Monoxide in Mainstream Tobacco
Smoke," Health Canada, 1999).

[0196] In the following example, a porous mass made with a highly active carbon (95% CCl
4 absorption) is compared with a porous mass made with a lower active carbon (60% CCl
4 absorption). The combined filters were made using a 10 mm section of the porous mass
plus a sufficient length of cellulose acetate to reach a targeted combined encapsulated
pressure drop of 69-70 mm of water. These filters were attached to a commercial tobacco
column and smoked on a Cerulean SM 450 smoking machine using the Canadian intense
smoking protocol
(i.e., T-115, "Determination of "Tar," Nicotine and Carbon Monoxide in Mainstream Tobacco
Smoke," Health Canada, 1999). The high active carbon was PICA RC 259, particle size 20x50, 95% activity (CCl
4 adsorption). The low active carbon was PICA PCA, particle size 30x70, 60% activity
(CCl
4 adsorption). The carbon loading of each porous mass element was 18.2 mg/mm, low active
carbon, and 16.7 mg/mm, high active carbon. The data is reported in relation to a
conventional cellulose acetate filter.

[0197] In the following example, the effect of particle size on encapsulated pressure drop
(EPD) is illustrated. Porous masses with carbons of various particle sizes were molded
into rods (length=39 mm and circumference=24.5 mm) by adding the mixture of carbon
and resin (GUR 2105) into a mold and heating (free sintering) the mixture at 200°C
for 40 minutes. Thereafter, the porous mass was removed from the mold and allowed
to cool to room temperature. The EPD's were determined for 10 porous masses and averaged.

[0200] In the following example, the encapsulated pressure drop was measured for a filter.
The porous masses were formed by mixing the binder particles (ultra high molecular
weight polyethylene) and active particles (carbon) at a desired weight ratio in a
tumbled jar until well mixed. A mold formed of stainless steel tube having a length
of 120 mm, an inside diameter of 7.747 mm, and a circumference of 24.34 mm. The circumference
of each of the molds was lined with a standard, non-porous filter plug wrap. With
a fitting on the bottom to close off the bottom of the mold, the mixture was then
placed into the paper-lined molds to reach to the top of the mold. The mold is tamped
(bounced) ten times off of a rubber stopper and then topped off to again reach the
top of the paper within the mold and bounced three times. The top of the mold is then
sealed and placed in an oven and heated, without the addition of pressure, to a temperature
of 220°C for 25 to 45 minutes, depending on the mold design, the molecular weight
of the binder particles, and the heat transfer. The encapsulated pressure drop was
measured in mm of water. Those components of the mixtures and test results are listed
below in Tables 15 - 20 below. The polyethylene binder particles used are from Ticona
Polymers LLC, a division of Celanese Corporation of Dallas, TX under the following
tradenames, the molecular weights are in parentheses: GUR® 2126 (approximately 4 x

[0202] The data shown in Figures 6 through 9 were generated from additional EPD testing
of porous masses of the present invention based on carbon loading and comparative
samples. The porous masses were formed by mixing the binder particles, specifically
ultra high molecular weight polyethylene chosen from GUR® 2105, GUR® X192, GUR® 4012,
and GUR® 8020), and active particles (carbon) at a desired weight ratio in a tumbled
jar until well mixed. A mold formed of stainless steel tube having a length of about
120 mm, an inside diameter of about 7.747 mm, and a circumference of about 24.5 mm
(theoretical) or about 17.4 (theoretical). The circumference of each of the molds
was lined with a standard, non-porous filter plug wrap. With a fitting on the bottom
to close off the bottom of the mold, the mixture was then placed into the paper-lined
molds to reach to the top of the mold. The mold is tapped (bounced) ten times off
of a rubber stopper and then topped off to again reach the top of the paper within
the mold and bounced three times. The top of the mold is then sealed and placed in
an oven and heated, without the addition of pressure, to a temperature of 220°C for
25 to 45 minutes, depending on the mold design, the molecular weight, and the heat
transfer. The length of the filter is then cut down to 100 mm. The circumference of
the filters tested is reported. These were substantially circular in shape. The encapsulated
pressure drop was measured in mm of water according to the CORESTA procedure.
[0203] Figure 6 is a comparative document that shows the results of encapsulated pressure
drop testing for carbon-on-tow filters having an average circumference of about 24.5
mm.
[0204] Figure 7 shows the results of encapsulated pressure drop testing for porous mass
filters of the present invention (comprising polyethylene and carbon) having an average
