CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Application Ser. No. 60/625,491 filed on Nov. 5, 2004 and U.S.
Provisional Application Ser. No. 60/669,604 filed on Apr. 8, 2005,
the contents of both of which are incorporated by reference
herein.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention is related to molded composite fabrics
and methods of making. More particularly, the present invention
relates to composite fabrics having a layer of non-woven fabric and
a layer of foam, where the composite fabrics include one or more
features molded therein.
[0004] 2. Description of Related Art
[0005] A variety of apparel garments or items include one or more
molded features. For example, brassieres include breast cups molded
in a composite fabric that has a fabric layer and a foam layer.
Similarly, protective products such as, but not limited to,
kneepads, elbow pads, and the like include features molded in a
composite fabric of fabric and foam.
[0006] In addition, a variety of non-apparel products such as, but
not limited to, automotive interiors, home furnishings, and others
can include such molded composite fabrics.
[0007] Typically, molded composite fabrics include a layer of
thermoplastic urethane (TPU) foam adhered to a knit fabric.
Unfortunately, TPU foam can be expensive and, thus, its use can be
cost prohibitive in many consumer product applications. Also, TPU
foams are sensitive to ultraviolet radiation present in ambient
light. Specifically, ultraviolet radiation tends to cause TPU foams
to yellow. In many applications, the yellowing of TPU foam is
unacceptable. Therefore, many TPU foams are laminated or faced on
both sides with a fabric layer to mask this yellowing. These
additional facing layers can add cost and weight to the resultant
product.
[0008] The selection of TPU foam and knit fabric are particularly
suited for use with one another in a molded composite fabric as
both the TPU foam and the knit fabric typically require high
molding temperatures and lengthy molding times (e.g., 400 degrees
Fahrenheit for about 60 seconds). Unfortunately, the high molding
temperatures and lengthy molding times can also make the use of
these composite fabrics cost prohibitive in many consumer product
applications.
[0009] Accordingly, there is a continuing need for molded composite
fabrics and methods of molding that overcome and/or mitigate one or
more of the aforementioned and other drawbacks and deficiencies of
the prior art.
BRIEF SUMMARY OF THE INVENTION
[0010] It is object of the present invention to provide a molded
composite fabric having a layer of non-woven fabric and a layer of
foam.
[0011] It is another object of the present invention to provide a
molded composite fabric having a layer non-woven fabric laminated
to both sides a layer of foam.
[0012] It is another object of the present invention to provide a
method of molding a composite fabric having a layer of non-woven
fabric and a layer of foam.
[0013] It is yet another object of the present invention to provide
a method of manufacturing a composite fabric from a non-woven
fabric and a layer of foam.
[0014] The aforementioned and other objects of the present
invention are provided by a molded composite fabric. The molded
composite fabric has a polyethylene foam layer and a first fabric
layer adhered to a first side of the polyethylene foam layer to
define a composite fabric. The molded composite fabric also
includes a feature molded in the composite fabric. The first fabric
layer has a non-woven fabric with a web of randomly disbursed
fibers.
[0015] A brassiere is provided that includes a garment body and a
pair of molded breast cups having a first fabric layer adhered to a
first side of a polyethylene foam layer. The first fabric layer has
a non-woven fabric with a web of randomly disbursed fibers.
[0016] A method of forming a molded non-woven fabric is also
provided. The method includes selecting a non-woven fabric having a
web of randomly disbursed fibers, exposing the non-woven fabric to
mechanical agitation, laminating the non-woven fabric to a first
side of a polyethylene foam layer to a composite fabric,
compressing the composite fabric between a top mold and a bottom
mold, and maintaining the composite fabric between the top and
bottom molds for a predetermined dwell time.
[0017] The above-described and other features and advantages of the
present invention will be appreciated and understood by those
skilled in the art from the following detailed description, and
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0024] Referring to the drawings and in particular to FIG. 1, a
molded composite fabric according to the present invention is
illustrated generally by reference numeral 10. Composite fabric 10
includes one or more fabric layers 12 adhered to a foam layer 14,
where the fabric and foam layers have been molded to define a
molded feature 16.
[0025] Feature 16 can be any desired feature as required by the end
use of composite fabric 10. For example, composite fabric 10 can
find use in a garment, such as a brassiere that requires breast
cups. In this example, feature 16 can define the breast cups of the
brassiere. In another example, composite fabric 10 can find use in
a protective apparel item, such as a kneepad that requires shaping
to approximate the shape of the protected body part. In yet another
example, composite fabric 10 can find use in an insulating apparel
garment, such as a coat, jacket, or sweatshirt. In this example,
feature 16 can be a plurality of expanded sections. In yet another
example, composite fabric 10 can find use in a decorative garment
where feature 16 is provided to add a pattern or design to the
garment.
[0026] It should be recognized that composite fabric 10 is
described above by way of example in use as a garment. Of course,
it is contemplated by the present disclosure for composite fabric
10 to find use in other non-garment applications.
[0027] Fabric layer 12 can be adhered to foam layer 14 by any known
method. Preferably, fabric layer 12 is adhered to foam layer 14 by
a solvent-based adhesive 18 such as, but not limited to, a web
adhesive, a film adhesive, a dot adhesive, and others. Of course,
it is contemplated by the present disclosure for fabric layer 12
and foam layer 14 to be adhered to one another by other methods
such as, but not limited to, sonic welding. It is further
contemplated by the present disclosure for fabric layer 12 and foam
layer 14 to be adhered one another continuously or discontinuously
across their mating surfaces.
[0028] For purposes of clarity, composite fabric 10 is described
herein having fabric layer 12 adhered to one side of foam layer 14.
However, it is also contemplated by the present disclosure for
composite fabric 10 to have a second fabric layer (not shown)
adhered to the opposite side of foam layer 14 so that the composite
fabric defines a three layer structure having a middle foam
layer.
[0029] Feature 16 is molded in composite fabric 10 after fabric
layer 12 and foam layer 14 are adhered to one another.
Advantageously, the materials of fabric layer 12 and foam layer 14
are configured for use with one another in composite fabric 10 as
both can be molded at low molding temperatures and short molding
times. Preferably, fabric layer 12 is made of materials that can be
molded at temperatures of less than about 300 degrees Fahrenheit
for about 20 seconds. Similarly, foam layer 14 is made of a
material that can withstand the molding temperatures composite
fabric 10 is exposed to during the molding process.
[0030] In an exemplary embodiment, fabric layer 12 is a non-woven
fabric having a web of randomly disbursed fibers or filaments
(hereinafter "fibers"), where the web preferably has uniform fiber
orientation in all directions. It is also preferred that the fibers
be bonded to and/or entangled with one another. The individual
fibers can be mono-component, multi-component, or any combinations
thereof.
[0031] Fabric layer 12 can be substantially inelastic or
inextensible (hereinafter "rigid") or can be substantially elastic
depending on the end use of composite fabric 10. In one exemplary
embodiment, fabric layer 12 provides hand feel acceptable for soft
fabric applications. The hand feel, as well as other physical
characteristics (e.g., elasticity) of fabric layer 12 can be
affected by the structure of the individual fibers, the composition
of the fiber materials, the size of the individual fibers, or any
combinations thereof.
[0032] For example, fabric layer 12 can include about 100% of a
polymer such as, but not limited to, nylon, polypropylene,
polyester, and other polymers. It is also contemplated by the
present invention for at least a portion of the fibers in fabric
layer 12 to be natural fibers (e.g., cotton, wool, hemp).
[0033] In another example, fabric layer 12 includes multi-component
fibers having a blend of polymers such as fibers having a blend of
a low-melting temperature polymer and a high-melting temperature
polymer. The low-melting temperature polymer allows the non-woven
fabric to be molded, while the high-melting temperature polymer
introduces structural stability to the fabric. By way of example,
the low-melting temperature polymer allows the non-woven fabric to
be molded at temperatures of less than about 300 degrees
Fahrenheit. In yet another embodiment, fabric layer 12 can include
at least two different mono-component fibers. One of the
mono-component fibers has a low-melting temperature polymer, while
another of the mono-component fibers has a high-melting temperature
polymer. In still another example, fabric layer 12 can include
fibers having two or more different diameters.
[0034] Accordingly, it is contemplated by the present disclosure
for fabric layer 12 to have individual fibers sized, positioned,
configured, and composition of materials sufficient to provide the
physical characteristics desired for composite fabric 10.
[0035] Fabric layer 12 can be produced using a non-woven process
such as, but not limited to, a melt-blowing process, a spun-bonding
process, a hydroentanglement process, a carding process, or any
combinations thereof.
[0036] An exemplary non-woven fabric suitable for fabric layer 12
used in soft fabric applications includes EVOLON, which is
commercially available from Freudenberg Nonwovens of Durham, N.C.
EVOLON is made using a spunbonding and hydroentangling process. The
spunbonded fibers are multi-component fibers having 70% PET and 30%
NYLON. During the hydroentanglement portion of the process, the
fibers are split into segments.
[0037] It has been found that the low molding temperatures afforded
by the use of non-woven fabric layer 12 advantageously allows foam
layer 14 to be made of foams also having a low molding temperature
such as, for example, polyethylene foam. Preferably, foam layer 14
is low-density polyethylene foam. Polyethylene foam is cheaper than
the TPU foams used in the prior art. In addition, polyethylene foam
does not yellow or discolor when exposed to ultraviolet radiation
present in ambient light and, thus, composite fabric 10 eliminates
the need for facing of foam layer 14 with additional protective
layers. As such, composite fabric 10 can be made lighter and less
expensive than prior art faced foams.
[0038] The thickness, softness and level of stretch of foam layer
14 and/or fabric layer 12 can be selected to match the desired
end-use of composite fabric 10.
[0039] Referring now to FIGS. 2 and 3, a molding step according to
the present invention for feature 16 is illustrated generally by
reference numeral 20. Composite fabric 10 is illustrated in FIG. 2
before the molding of feature 16 and is illustrated in FIG. 3
during the molding of the feature.
[0040] Molding step 20 includes a heating station 22 and a molding
station 24. Heating station 22 can include, for example, one or
more radiant heating plates for heating composite fabric 10 as it
is moved past the heating station in a machine direction 26 towards
molding station 24.
[0041] Heating station 22 heats composite fabric 10 so that the
composite fabric is heated to a predetermined temperature. For
example, heating station 22 heats composite fabric 10 to a
temperature of less than about 375 degrees Fahrenheit. In a
preferred embodiment, heating station 22 heats composite fabric 10
to about 300 degrees Fahrenheit.
[0042] Next, molding step 20 moves the heated composite fabric 10
to molding station 24. Molding station 24 includes a molding cavity
28 having a desired shape. In the illustrated embodiment, molding
cavity 28 has a shape for forming a breast cup for a brassiere.
Preferably, molding station 24 is a vacuum molding station that
draws the heated composite fabric 10 into cavity 28 in a molding
direction 30. Molding station 24 maintains composite fabric 10 in
cavity 28 for a predetermined dwell time. For example, molding
station 24 maintains composite fabric 10 in cavity 28 for less than
about 30 seconds. In a preferred embodiment, molding station 24
maintains composite fabric 10 in cavity 28 for about 20
seconds.
[0043] Advantageously, the predetermined temperature and dwell time
of molding step 20 (e.g., 300 degrees Fahrenheit for about 20
seconds) are less than those currently used in the manufacture of
composites having TPU foam and knit fabric (e.g., 400 degrees
Fahrenheit for about 120 seconds). Thus, molding step 20 can form
composite fabric 10 into the desired shape faster and more
economically than prior processes.
[0044] Referring now to FIG. 4, a manufacturing process according
to the present invention for making composite fabric 10 is
illustrated generally by reference numeral 40. In addition to
molding step 20 described above, manufacturing process 40 includes
a washing or agitation step 42 and a lamination step 44. During
process 40, fabric layer 12 is first exposed to agitation step 42,
then the fabric layer and foam layer 14 are adhered to one another
during lamination step 44 to define composite fabric 10, and
finally the composite fabric is molded during molding step 20.
[0045] Preferably, agitation step 42 exposes the desired non-woven
fabric 12 to mechanical agitation, more preferably in the presence
of a wetting agent such as, but not limited to, water and/or fabric
softener. For example, it is contemplated for agitation step 42 to
be carried out in a typical household washing machine or a typical
industrial dyeing process (processed with or with out dyes). In
this manner, agitation step 42 subjects fabric layer 12 to
agitation in the presence of the wetting agent to permit the
individual fibers of the non-woven fabric to achieve a desired
position with respect to each other as discussed immediately
below.
[0046] While not wishing to be bound by a particular theory, it is
believed that agitation step 42 introduces an element of freedom to
the individual fibers of the non-woven fabric 12. It is believed
that this freedom allows the fibers to move and/or slide with
respect to one another to mitigate tearing of the fabric during
subsequent lamination and molding steps. For example, it is
believed that the agitation of agitation step 42 weakens and/or
breaks at least some of the bonds and/or entanglements between the
individual fibers of the non-woven fabric 12.
[0047] In a preferred embodiment of agitation step 42, the
agitation step includes the use of fabric softener as the wetting
agent. While not wishing to be bound by a particular theory, it is
believed that the fabric softener provides a degree of lubrication
to the individual fibers of the non-woven fabric. It is believed
that the lubrication of the individual fibers allows the fibers to
slide with respect to one another.
[0048] After agitation step 42, fabric layer 12 and foam layer 14
are adhered to one another in lamination step 44. During lamination
step 44, fabric layer 12 is adhered to foam layer 14 by, for
example, applying an adhesive to the fabric and/or foam layers and
compressing the layers together to define composite fabric 10.
[0049] In some embodiments of the present invention, manufacturing
process 40 can include a perforating step 46 before lamination step
44. Many of the low molding temperature foams available for use as
foam layer 14 (e.g., low-density polyethylene foam) are closed cell
foams. Thus, it is contemplated by the present invention for
manufacturing process 40 to include perforating step 46 to induce a
predetermined level of permeability and/or breathability to foam
layer 14. In a preferred embodiment, perforating step 46 removes
material from foam layer 14 to provide the desired permeability.
For example, perforating step 46 can punch a plurality of holes
through foam layer 14.
[0050] After defining composite fabric 10 at lamination step 44,
manufacturing process 40 exposes the composite fabric to molding
process 20 to define one or more molded features 16 in the
composite fabric.
[0051] It should be recognized that process 40 is described above
having lamination step 44 before molding step 20. However, it is
also contemplated by the present disclosure for the lamination and
molding steps to occur simultaneously with one another.
[0052] Advantageously, the composite fabric of the present
invention overcomes the expense and weight associated with prior
art molded composite fabrics. For example, molded composite fabric
10 can be used in the formation of a brassiere 50 as illustrated in
FIG. 5. Brassiere 50 includes a garment body 52 and a pair of
breast cups 54. Garment body 52 includes only non-woven fabric
layer 12, while breast cups 54 include both the non-woven fabric
layer and foam layer 14. Thus, brassiere 50 includes composite
fabric 10 only in the areas of the breast cups, which are molded to
a desired cup depth. Brassiere 50 can be configured so that foam
layer 14 of breast cups 54 is in contact with the user when worn as
shown. Alternately, brassiere 50 can be configured so that fabric
layer 12 of breast cups 54 is in contact with the user when
worn.
[0053] An alternate exemplary embodiment of a brassiere 60 having
molded composite fabric 10 is illustrated in FIG. 6. Brassiere 60
includes a garment body 62 and a pair of molded breast cup inserts
64. Garment body 62 can be one or more layers of woven and/or
non-woven fabrics. Inserts 64 are formed from composite fabric 10
and, thus, include both non-woven fabric layer 12 and foam layer
14. Inserts 64 can be secured to garment body 62 using any known
method such as, but not limited to, sewn seams, adhesives, welds,
and others. Preferably, inserts 64 are secured to garment body 62
so that foam layer 14 is in contact with the garment body and
fabric layer 12 is in contact with the user when worn as shown in
FIG. 6. Alternately, inserts 64 can be secured to garment body 62
so that fabric layer 12 is in contact with the garment body and
foam layer 14 is in contact with the user when worn.
[0054] It should also be noted that the terms "first", "second",
"third", "upper", "lower", and the like may be used herein to
modify various elements. These modifiers do not imply a spatial,
sequential, or hierarchical order to the modified elements unless
specifically stated.
[0055] While the present disclosure has been described with
reference to one or more exemplary embodiments, it will be
understood by those skilled in the art that various changes may be
made and equivalents may be substituted for elements thereof
without departing from the scope of the present disclosure. In
addition, many modifications may be made to adapt a particular
situation or material to the teachings of the disclosure without
departing from the scope thereof. Therefore, it is intended that
the present disclosure not be limited to the particular
embodiment(s) disclosed as the best mode contemplated, but that the
disclosure will include all embodiments falling within the scope of
the appended claims.
