Abstract

A woven trim piece is provided that utilizes "grip" yarns in the warp direction to increase the coefficient of friction of the trim piece. The grip yarns are interlaced with a plurality of filling yarns to form a repeating pattern of floats on a first face of the trim piece, such that a high percentage of the first face of the trim piece comprises grip yarns.

Description

WOVEN TRIM PIECE

FIELD OF THE INVENTION

The present invention relates to a woven trim piece, that, when incorporated into an article, provides additional traction and friction for securing the article to a wearer’s body.

BACKGROUND OF THE INVENTION

Traditional trim pieces, such as waistbands, may be used to secure the waist portion of a short or pant around the torso region of a wearer. These trim pieces, moreover, may use post-processing treatments such as silicone on the inner-facing surface of the trim piece to provide a degree of traction to help, for instance, keep a shirt or jersey that is tucked into the pant or short from shifting or becoming untucked during wear. However, sweat or perspiration from the wearer may cause these types of post-processing treatments to become slippery which may negatively impact its traction function.

DETAILED DESCRIPTION OF THE INVENTION

The subject matter of the present invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this disclosure. Rather, the inventors have contemplated that the disclosed and claimed subject matter might also be embodied in other ways, to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the terms“step” and/or“block” might be used herein to connote different elements of methods employed, the terms should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly stated.

At a high level, aspects herein are directed to a woven trim piece incorporating one or more yarns having a very high number of filaments within a single yam strand. For instance, a single yam strand may comprise up to 7000 or greater number of filaments such that the denier per filament of the single yam strand is less than or equal to 0.01 (referred to herein as“grip yarns”). In exemplary aspects, the grip yam may comprise polyethylene terephthalate (PET) (commonly known as polyester). The large number of filaments provides a large surface-to-volume ratio for the single yam strand which contributes to the gripping function of the yarn. To describe it differently, the large number of filaments within the single yarn strand causes the single yarn strand to have a higher coefficient of friction as compared to, for example, more typical yams that incorporate a smaller number of filaments within a single yam strand such as yarns that incorporate from between, for example, 50 filaments to 500 filaments per single yam strand.

The grip yarns are incorporated into the woven trim piece in such a way that a greater percentage of the grip yams are exposed on a first face of the woven trim piece as compared to a second opposite face of the woven trim piece. In exemplary aspects, the first face of the woven trim piece may comprise an inner-facing surface of the trim piece when the trim piece is incorporated into an article of apparel. One way of achieving a greater percentage of the grip yarns on the first face is by utilizing the grip yarns as warp yams and repetitively floating the grip yams over, for instance, three or more filling yams on the first face of the trim piece. Moreover, the grip yarn floats are oriented so that their long axes are parallel to a first longitudinal edge and a second longitudinal edge of the woven trim piece.

Continuing, when the trim piece is utilized as, for example, a waistband for a short or pant, the orientation of the grip yam floats would be generally perpendicular to gravitational forces when a wearer wearing the short or pant is in a standing position. Due to their gripping function, the grip yam floats may help to prevent a short or pant from shifting downward during wear, especially wear during vigorous activities such as basketball or soccer. Further, the orientation of the grip yam floats would also be generally perpendicular to tensioning forces created by, for example, an upward movement of the wearer’s arms or shoulders or from a twisting of the wearer’s torso. Again, due to their gripping function, the grip yarn floats may help to prevent a jersey or shirt tucked into the waistband from becoming untucked or displaced during wear.

The woven trim piece may also incorporate non-grip yams having a low moisture regain to help provide moisture-management features to the woven trim piece as further described below. In exemplary aspects, the non-grip yarns may comprise PET yarns incorporated as warp yarns that are woven or interlaced with filling yams such that a greater percentage of the non-grip PET warp yarns are exposed on the second face of the woven trim piece. This may be achieved by repetitively floating the non-grip PET warp yarns over, for instance, three or more filling yarns on the second face of the woven trim piece. When the trim piece is utilized in an article of apparel such that the second face of the trim piece comprises an outer-facing surface, moisture produced by the wearer may be wicked to the outer-surface of the trim piece through capillary action between the PET yarns and/or the PET filaments. Because a greater percentage of the non-grip PET yams are present on the outer-facing surface as compared to the inner-facing surface, the moisture may spread out and be removed through evaporation. Non-grip PET yarns may also be utilized as filling yarns in accordance with aspects herein.

Accordingly, aspects herein are directed to a woven trim piece comprising a first longitudinal edge, a second longitudinal edge opposite the first longitudinal edge, a first face, and a second face opposite the first face. In exemplary aspects, the woven trim piece further comprises a first plurality of warp yarns extending parallel to at least the first longitudinal edge, the first plurality of warp yarns each having a denier per filament of less than or equal to 0.01, a second plurality of warp yams extending parallel to at least the first longitudinal edge, and a plurality of filling yams extending generally perpendicular to at least the first longitudinal edge. In accordance with aspects herein, the first plurality of warp yarns are interlaced with the plurality of filling yarns to form a repeating pattern of floats on the first face of the trim piece, and the second plurality of warp yams are interlaced with the plurality of filling yams to form a repeating pattern of floats on the second face of the trim piece.

Further aspects herein are directed to a woven waistband comprising a first longitudinal edge, a second longitudinal edge opposite the first longitudinal edge, a first face and a second face opposite the first face. The woven waistband comprises a first plurality of warp yarns extending parallel to at least the first longitudinal edge, the first plurality of warp yams each having a denier per filament of less than or equal to 0.01, and a second plurality of warp yams extending parallel to at least the first longitudinal edge, and a plurality of filling yams extending generally perpendicular to at least the first longitudinal edge, wherein the first plurality of warp yams are interlaced with the plurality of filling yams to form a repeating pattern of floats on the first face of the woven waistband, and the second plurality of warp yarns are interlaced with the plurality of filling yarns to form a repeating pattern of floats on the second face of the woven waistband.

Still further, aspects herein are generally directed to a lower-body garment comprising a torso portion defining a waist opening, two leg portions extending from the torso portion, each leg portion defining a leg opening, and a woven waistband. The woven waistband comprises a first longitudinal edge, a second longitudinal edge opposite the first longitudinal edge, wherein the second longitudinal edge is coupled to the waist opening of the torso portion, a first face, a second face opposite the first face. The lower-body garment further comprises a first plurality of warp yarns extending parallel to at least the first longitudinal edge, the first plurality of warp yarns each having a denier per filament of less than or equal to 0.01, a second plurality of warp yams extending parallel to at least the first longitudinal edge, and a plurality of filling yams extending generally perpendicular to at least the first longitudinal edge, wherein the first plurality of warp yams are interlaced with the plurality of filling yarns to form a repeating pattern of floats on the first face of the woven waistband, and the second plurality of warp yarns are interlaced with the plurality of filling yams to form a repeating pattern of floats on the second face of the woven waistband.

The term“yarn” as used herein may comprise any type of filament yarn such as a monofilament yam or a multi-filament yarn that forms a continuous strand. The term yam may also mean an assemblage of fibers twisted or laid together so as to form a continuous strand. The yams may comprise synthetic yarns such as PET yarns, polyamide (e.g., nylon) yarns, and/or elastic yarns and may also comprise natural yams such as, for example, cotton. The term“weaving” as used herein may mean a process by which yarns are interlaced at right angles. As used herein, the term“interlacing” may be defined as the point at which a yarn changes its position from one side or one face of the textile to the other side or other face of the textile. As used throughout this disclosure, the term“one-over-one interlacing” refers to a weaving stmcture in which a warp yarn is threaded over a first weft yam, under an adjacent second weft yarn, and over an adjacent third weft yam. The term “float” as used herein may be defined as a yarn that crosses over more than one perpendicularly oriented yarn at a time before changing position to the other side or face of the textile. The term“warp yarn” as used herein refers to a yarn that is threaded through a loom in a woven fabric such that it is parallel to the selvage. The term“filling yarn” (or “weft yam”) as used herein refers to a yam that is perpendicular to the selvage of the woven fabric and that is interlaced with warp yams.

Continuing, the components of a woven trim piece comprise warp yams and filling (or weft) yams, where the warp yams extend in the lengthwise direction of the trim piece and the filling yams extend in the cross-wise direction of the trim piece (i.e., extend across the width of the trim piece). The woven trim piece, in exemplary aspects, may be woven during a single weaving event. As such, a particular warp yarn may extend the length of the woven trim piece. The present disclosure contemplates a number of different types of looms used to weave the woven trim piece such as air-jet looms, rapier looms, water-jet looms, projectile looms, multi-width or multi-beam looms, multiple-shed looms, circular looms, Jacquard looms, and the like.

Positional terms used herein such as “superior,” “inferior,” “medial,” “lateral,” “upper,” “lower,” “side,” “front,” “back,” “horizontal,” “vertical,” “diagonal,” “outer-facing surface,”“inner-facing surface” and the like are to be given their common meaning with respect to a garment or apparel item incorporating the woven trim piece being worn as it is intended to be worn by a hypothetical wearer standing in an upright position (i.e., standing in anatomical position). Further, the phrase“configured to contact,” or other similar phrases used when describing different portions of the garment or apparel item in relation to a wearer refer to a garment or apparel item appropriately sized for the particular wearer.

Turning now to FIG. 1, a perspective view of a woven trim piece 100 is depicted, in accordance with aspects herein. The woven trim piece 100 is shown in a circular or circumferential form to indicate how it would likely be incorporated into a garment or an article of apparel. For example, the woven trim piece 100 may be incorporated as a waistband in a short or pant, an underhand of a bra or support garment, a cuff of a jacket or shirt, a cuff of a pant or short, a bottom hem of a jacket or coat, and the like. In reality, the woven trim piece 100 would comprise a longitudinal strip when taken off the loom, where the strip would have a first end and a second end opposite the first end. The first and second ends may be joined to produce the woven trim piece 100 of FIG. 1.

The woven trim piece 100 comprises a first face 102 and a second face 104 opposite the first face 102. In accordance with aspects herein, the first face 102 may face toward a wearer when a garment incorporating the trim piece 100 is donned, with the second face 104 being positioned opposite the first face (e.g., away from a wearer when the garment is donned). However, it is contemplated herein that the first face 102 may also comprise an outer-facing surface of the trim piece 100, and the second face 104 may comprise an inner- facing surface of the trim piece 100. Any and all aspects, and any variation thereof, are contemplated as being within aspects herein. For discussion purposes herein, the first face 102 will generally be referred to as the portion of the woven trim piece 100 which faces a wearer’s body surface when the garment is donned (otherwise known as an“inner-facing surface”), and the second face 104 will generally be referred to as the portion of the woven trim piece 100 which faces away from the wearer when the garment is donned (otherwise known as an“outer- facing surface”). As depicted in FIG. 1, the woven trim piece 100 comprises a first longitudinal edge 112 and a second longitudinal edge 114 opposite the first longitudinal edge 112, with the first face 102 and the second face 104 extending between the first longitudinal edge 112 and the second longitudinal edge 114.

Turning now to FIG. 2, a detailed view of the first face 102 of the woven trim piece 100 is depicted, in accordance with aspects herein. As described herein, the woven trim piece 100 is constructed through a weaving process. As depicted in FIG. 2, the yarns positioned parallel to the first longitudinal edge 112 and the second longitudinal edge 114 comprise warp yams, while the yarns positioned perpendicular to the first longitudinal edge 112 and the second longitudinal edge 114 comprise filling yarns. More particularly, the warp yarns comprise at least a first plurality of grip yarns 106 (shown with hatching) and a second plurality of non-grip yarns 108 (shown without hatching). And the filling yarns comprise at least a third plurality of non-grip filling yarns 110 (shown without hatching).

FIG. 3 illustrates a magnified view of the first face 102 of the woven trim piece 100 taken at the area indicated in FIG. 2 in accordance with aspects herein. As shown in FIG. 3, grip yarns 106 extend parallel to the first longitudinal edge 112 and the second longitudinal edge 114. As described above, the grip yams 106 generally comprise PET yarns having a high number of filaments (e.g., 7000 or greater) per single yarn strand such that the denier per filament of the grip yarn 108 is around 0.01 or less. In exemplary aspects, the grip yarns 106 may be formed through an“islands-in-the-process.”

Continuing, the non-grip yams 108 also extend parallel to the first longitudinal edge 112 and the second longitudinal edge 114. Examples of non-grip yarns 108 may be a natural yarn, such as cotton, or a synthetic yam, such as PET or polyamide yams. In one exemplary aspect, the non-grip yams 108 comprise an air-jet-spun 150 denier/l44 filament

PET yarn. Use of air-jet-spun yarns contributes to a softer feel or hand. Also depicted in

FIG. 3 are the plurality of filling yams 110 which extend generally perpendicular to at least the first longitudinal edge 112. When viewed in the context of weaving, the plurality of filling yarns 110 may also be referred to as weft yams. Examples of filling yarns 110 may be a natural yarn, such as cotton, or a synthetic yam, such as polyester or nylon. In one exemplary aspect, the filling yams 110 comprise a textured 150 denier/48 filament PET yam.

As depicted in FIG. 3, and in one exemplary aspect, the grip yarns 106 alternate every other yarn with the non-grip yams 108 along the length of the trim piece 100. Further, in an exemplary aspect, the weaving pattern of the trim piece 100 is such that each individual grip yarn, such as grip yarn 107, is floated over a first set of three filling yams 110 (e.g., filling yarns l lOa, l lOb, and llOc) and is then interlaced with a second set of filling yams 110 (e.g., filling yarns l lOd, llOe, and llOf) in a one-over-one pattern before being floated over a third set of three filling yarns 110 (e.g., filling yams llOg, l lOh, and l lOi). This pattern continues the length of the trim piece 100. Further, the remaining grip yams 106 are woven in the same pattern such that floats formed from the individual grip yams 106 are vertically aligned across the width of the trim piece 100. To describe the weaving pattern in different way, each float, such as float 109, has a long axis 111, and the long axis 111 of the float 109 is oriented parallel to the first longitudinal edge 112 and to the second longitudinal edge 114.

The result of the weaving pattern shown in FIG. 3 is that the surface area of the first face 102 of the trim piece 100 comprises a greater percentage of the grip yarns 106 as compared to the non-grip yams 108. Another result of the weaving pattern shown in FIG. 3 is that the long axes of the floats formed from the grip yams 106, such as the long axis 111 of the float 109, are configured to be oriented perpendicular to likely tensioning forces and/or gravitational forces when the trim piece 100 is incorporated into a garment.

A functional benefit achieved by having a greater percentage of the grip yams 106 on the first face 102 of the trim piece 100, is that the first face 102 may have a higher coefficient of friction as compared to, for example, the second face 104 of the trim piece 100 or as compared to trim pieces that do not incorporate grip yarns. Testing with ASTM D 1894.2001 standards indicates that the trim piece 100 increases in coefficient of friction when transitioning from dry conditions to wet conditions, while traditional silicone treatments decrease in coefficient of friction when transitioning from dry conditions to wet conditions. For example, testing with ASTM D1894.2001 standards indicates that the coefficient of friction of the trim piece 100 increases from about 15 to about 45 percent when transitioning from dry conditions to wet conditions (as used herein, the term“about” means within ±10%). In exemplary aspects, this may be due to the grip yams having a high number of filaments per yam strand, enabling the grip yam to trap a larger volume of water between the filaments as compared to yams having a fewer number of filaments. This may result in swelling of the grip yarn which results in a greater surface area (i.e., a greater surface-to- volume ratio) for providing a frictional force. Said another way, the greater amount of filaments in the grip yarns allows for the grip yam to trap more moisture than a non-grip yam, and thus, the surface area expansion of a grip yarn is greater than the surface area expansion of a non-grip yarn.

A functional benefit is also achieved by having the long axes of the grip yam floats oriented parallel to the first and second longitudinal edges 112/114 and perpendicular to likely gravitational forces and/or tensioning forces. For instance, when the trim piece 100 is incorporated into, for example, a waistband of a pant or short, gravitational forces exert a downward force on the waistband. By having the grip yam floats oriented perpendicular to this gravitational force, the gripping function of the grip yams 106 helps to maintain the waistband in a relatively fixed position. Using this same example, when a shirt or jersey is tucked into the waistband it may be subject to upward tensioning forces produced by, for example, the wearer raising her arms. This may be especially tme during athletic activities such as basketball. By having the grip yarn floats oriented generally perpendicular to this type of tensioning force, the gripping function of the grip yarns 106 helps to keep the shirt or jersey tucked in and may prevent the shirt or jersey from twisting during wear.

Turning now to FIG. 4, the second face 104 of the woven trim piece 100 is depicted, in accordance with aspects herein. Similar to what is depicted in FIG. 2, FIG. 4 depicts that the second face 104 extends between the first longitudinal edge 112 and the second longitudinal edge 114. In accordance with aspects herein, the second face 104 differs from the first face 102 inasmuch as the non-grip yams 108 are floated over the filling yams 110, as opposed to the grip yarns 106 being floated over the filling yarns. To describe it differently, the grip yarns 106 form floats on the first face 102 of the woven trim piece 100, while the non-grip yarns 108 form floats on the second face 104 of the woven trim piece 100.

Turning now to FIG. 5, a magnified view of the second face 104 of the woven trim piece 100 taken at the area indicated in FIG. 4 is depicted. The weaving pattern of the second face 104 is the inverse of the weaving pattern shown in FIG. 3. As shown, the non grip yarns 108 alternate every other yam with the grip yarns 106 along the length of the trim piece 100. Moreover, each individual non-grip yam, such as non-grip yarn 113, is floated over a first set of three filling yams 110 (e.g., filling yarns llOj, l lOk, and 1101) and is then interlaced with a second set of filling yams (e.g., filling yams l lOm, 110h, and l lOo) in a one-over-one pattern before being floated over a third set of filling yarns 110 (e.g., filling yams l lOp, llOq, and l lOr). This pattern continues the length of the trim piece 100. The remaining non-grip yams 108 are woven in the same pattern such that floats formed from the individual non-grip yams 108 are vertically aligned across the width of the trim piece 100. Similar to the floats formed from the grip yarns 106, each float formed from the non-grip yams 108 has a long axis and the long axes of the non-grip yarn floats are oriented parallel to the first longitudinal edge 112 and the second longitudinal edge 114. Because of this construction, the second face 104 comprises a greater percentage of the non-grip yarns 108 than the grip yams 106. As depicted in FIGs. 3 and 5, the grip yams 106 and the non-grip yams 108 are depicted as being floated over three filling yams 110. This depiction is merely exemplary, and the grip yams 106 and the non-grip yarns 108 may be floated over greater than three filling yarns 110 to provide the desired characteristics of the woven trim piece 100.

A functional benefit achieved by having a greater percentage of non-grip yarns 108 on the second face 104 of the trim piece 100, is that the non-grip yarns 108 may help to spread moisture in the form of perspiration or sweat over the second face 104 of the trim piece 104 where it can more easily evaporate leading to quicker drying times for the trim piece 100. This may be facilitated by forming the non-grip yams 108 from, for example, PET or polyamide. These yarns typically absorb less moisture than, for example, cotton yams and thus dry quicker. For instance, the moisture regain for textiles formed from PET yams is around 0.4% and the moisture regain for textiles formed from polyamide yams is around 4.5%. This is compared to textiles formed from, for example, cotton that have a moisture regain of around 8.5%. Moreover, because PET and polyamide yams typically absorb less moisture than, for example, cotton yarns, these yarn types promote moisture wicking via capillary action between the yarns and/or filaments forming the yarns. Thus, to reiterate, sweat or moisture produced by a wearer may be transported to the second face 104 of the trim piece 100 where the non-grip yam floats facilitate the spread of the moisture over the second face 104.

Turning now to FIG. 6, an exemplary weaving diagram 600 of the woven trim piece 100 is depicted. The weaving diagram 600 is depicted as a cross-sectional view cut parallel to the warp yams. As depicted in FIG. 6, the warp yarns comprise grip yam 106 and non-grip yam 108, and the filling yarns are represented by reference numeral 110. In FIG. 6, the grip yam 106 is woven in a repeating pattern such that the grip yarn 106 passes over (or floats over) three adjacent filling yarns 110 on the first face 102 of the trim piece 100 before traveling to the second face 104 of the trim piece. Then the grip yam 106 interlaces with a next set of three adjacent filling yams 110 in a one-over-one interlacing pattern. After the set of one-over-one interlacings, the grip yam 106 passes over (or floats over) a next set of three filling yams 110 on the first face 102 of the trim piece 100 before traveling to the second face 104 of the trim piece 100.

Continuing, the non-grip yarn 108 is woven in the inverse pattern such that the non-grip yam floats are positioned on the second face 104 of the trim piece. To describe differently, after the grip yam 106 and the non-grip yarn 108 are“floated” over three adjacent filling yams 110 on opposite faces of the trim piece 100, the grip yarn 106 and non-grip yarn

108 are woven in an over-under-over configuration (i.e., an odd number of interlacings), such that the next float in the pattern for the grip yarn 106 appears on the same face of the trim piece 100 (i.e., the first face 102) as the previous float for the grip yarn 106, and the next float in the pattern for the non-grip yarn 108 appears on the same face of the trim piece 100 (i.e., the second face 104) as the previous float for the non-grip yam 108.

It is contemplated herein that the trim piece 100 may comprise one or more elastic yarns (yams that may provide a maximum stretch greater than 200% under load prior to returning to its non-stretched state when the load is removed). An exemplary elastic yarn may comprise, for example, an 840 denier elastic yam that is covered with a PET yam. In order to provide circumferential tensioning of the trim piece 100 when the trim piece 100 is in the form of a waistband, underhand, and the like, the elastic yarns may be positioned in the warp such that they extend the length of the trim piece 100. FIG. 7 illustrates an exemplary weaving diagram 700 of a woven trim piece having an elastic warp yam 109 (shown with black shading) incorporated therein. Similar to FIG. 6, the weaving diagram 700 is depicted as a cross-sectional view cut parallel to the warp yarns. The weaving configuration of the grip yarn 106 and the non-grip yarn 108 in FIG. 7 is similar to the weaving configuration of the grip yarn 106 and the non-grip yam 108 depicted in FIG. 6. The elastic yam 109 is interlaced with the filling yarns 110 in an over-under-over configuration (i.e., a one-over-one interlacing pattern). Similar to the grip yam 106 and the non-grip yam 108, the elastic yam

109 is configured to extend parallel to at least the first longitudinal edge 112 and the second longitudinal edge 114 of the trim piece 100

Turning now to FIG. 8A, a different view of the weaving pattern 700 is depicted, in accordance with aspects herein. In FIG. 8A, which illustrates the second face 104 of an exemplary trim piece, the warp yarns alternate in a triplet-like pattern 805, with the grip yam 106 followed by the non-grip yam 108 followed by the elastic yam 109. The warp yam pattern then repeats itself, with another grip yam 106 being placed sequentially after or adjacent to the preceding elastic yam 109. As discussed with regards to FIG. 7, the elastic yams 109 may be used to achieve a desired stretch characteristic of the woven trim piece 100. Similar to FIG. 8 A, FIG. 8B depicts a triplet-like pattern 810, in an alternate configuration. As depicted in FIG. 8B, the triplet- like pattern 810 defines the warp yams of this weaving diagram, beginning with the grip yam 106 and ending with the non-grip yam 108, with the elastic yam 109 positioned between the grip yarn 106 and the non-grip yarn 108. This triplet like pattern is repeated throughout the structure of FIG. 8B. Again, the elastic yarns 109 may be used to achieve a desired stretch characteristic of the woven trim piece 100.

As stated above, it is contemplated herein that the grip yarns 106 and the non grip yams 108 may be floated over more than three filling yarns. An example of this is shown in FIG. 9 which depicts a weaving diagram 900 taken in cross-section parallel to the warp yarns. The weaving diagram 900 depicts, for instance, grip yam 106 being floated over five filling yams 110 on the first face 102 of the trim piece, and non-grip yarn 108 being floated over the same five filling yarns on the second face 104 of the trim piece 100. Similar to the weave diagram 600 and 700, adjacent floats for the grip yam 106 and adjacent floats for the non-grip yam 108 are separated by a set of one-over-one interlacings (three interlacings in this example). The weaving diagram 900 further illustrates the incorporation of the elastic yarn 109 that is woven in an under-over-under configuration (i.e., a one-over- one interlacing pattern). It is contemplated herein, that the elastic yam 109 may not be utilized.

Turning now to FIG. 10, the woven trim piece 100 is depicted as incorporated into a lower-body garment 200. In FIG. 10, the lower-body garment 200 is depicted as a pair of athletic shorts, although other types of lower-body garments are considered to be within the scope of this disclosure. For example, the lower-body garment 200 may be a pair of sweatpants or another type of athletic pant. Alternatively, the lower-body garment 200 may be tailored specifically to one sport, such as a pair of football pants. Any and all types of lower-body garments are considered to be within the scope of this disclosure. In FIG. 10, the lower-body garment 200 comprises a torso portion 220 which defines a waist opening 222, and two leg portions 224A and 224B extending from the torso portion 220. Additionally, each leg portion 224A and 224B defines a leg opening 226 A and 2226B. The woven trim piece 100 described herein is affixed to the lower-body garment 200 (via, for instance, stitching, bonding, welding, and the like), such that the woven trim piece 100 at least partially defines the waist opening 222. Accordingly, in FIG. 10, the woven trim piece 100 serves as a waistband for securing the lower-body garment 200 to the body of a wearer. Additionally, in accordance with aspects herein, the woven trim piece 100 may be integrally formed into the lower-body garment 200, such that the woven trim piece 100 and lower-body garment 200 comprise a unitary construction.

The first face 102 of the trim piece 100 is positioned to face inwards so as to be adjacent to a body surface of a wearer when the lower-body garment 200 is worn. As explained above, the first face 102 of the trim piece 100 comprises a greater percentage of grip yams 106 as compared to the second face 104 of the trim piece 100. The greater percentage of grip yarns 106 helps to increase the coefficient of friction of the first face 102 which may help to prevent the lower-body garment 200 from shifting during wear and also may help shirts or jerseys tucked into the lower-body garment 200 from becoming untucked. The second face 104 of the trim piece 100 is positioned to face outwards when the lower- body garment 200 is worn. The second face 104 comprises a greater percentage of non- grip yams 108 (e.g., PET yarns) as compared to the first face 102 of the trim piece 100. The greater percentage of non-grip yarns 108 helps to spread any moisture wicked from the wearer’s body over the second face 104 where it can subsequently evaporate.

Turning now to FIG. 11, the woven trim piece 100 is depicted as incorporated into an upper-body garment 300. In FIG. 11, the upper-body garment 300 is depicted as a support garment such as a sport bra, although other types of upper-body garments are considered to be within the scope of this disclosure. For example, the upper-body garment 300 may be a sweatshirt, a hoodie, a mnning or winter jacket, a short or long sleeve t-shirt, and the like and the trim piece 100 may comprise a bottom waistband, a cuff, a collar, and the like. In FIG. 11, the upper-body garment 300 comprises a torso portion 320, a lower-body opening 322, and two arm holes 324A and 324B. The woven trim piece 100 is affixed to the upper-body garment 300 such that the woven trim piece 100 at least partially defines the lower-body opening 322. The trim piece 100 as incorporated into the upper-body garment

300 would serve similar purposes as that described in relation to the lower-body garment 200 (e.g., prevent the garment 300 from shifting during wear, and the like).

Turning now to FIG. 12, the woven trim piece 100 described herein is depicted as further comprising a graphic 116 created by, for example, sublimation printing. The graphic 116 is represented in FIG. 12 as two small stars with a larger star placed therebetween, although this configuration is merely exemplary of one type of graphic considered to be within the scope of this disclosure. As described herein, sublimation printing produces a print or graphic by heat-transferring sublimation dyes throughout a fabric as opposed to layering inks onto a fabric’s surface. It is known that sublimation dyes have an affinity to (or optimally bond with) PET yarns and are better absorbed by textiles formed from PET as opposed to textiles formed from, for example, cotton. As described throughout this disclosure, the woven waistband 100 comprises a large percentage of PET, as both the non-grip warp yarns 108 and the filling yarns 110 may comprise PET filaments. By forming the second face 104 of the woven trim piece 100 to comprise a greater percentage of PET, the second face 104 presents an optimized surface for sublimation printing.

Examples of the present invention have been described with the intent to be illustrative rather than restrictive. Alternative examples will become apparent to those skilled in the art that do not depart from its scope. A skilled artisan may develop alternative means of implementing the aforementioned improvements without departing from the scope of the present invention.

It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations and are contemplated within the scope of the claims.
