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.
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.
Examples of the present invention are described in detail below with reference to the attached drawing figures, wherein:
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 yarn strand. For instance, a single yarn strand may comprise up to 7000 or greater number of filaments such that the denier per filament of the single yarn strand is less than or equal to 0.01 (referred to herein as “grip yarns”). In exemplary aspects, the grip yarn may comprise polyethylene terephthalate (PET) (commonly known as polyester). The large number of filaments provides a large surface-to-volume ratio for the single yarn 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 yarns that incorporate a smaller number of filaments within a single yarn strand such as yarns that incorporate from between, for example, 50 filaments to 500 filaments per single yarn strand.
The grip yarns are incorporated into the woven trim piece in such a way that a greater percentage of the grip yarns 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 yarns and repetitively floating the grip yarns over, for instance, three or more filling yarns 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 yarn 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 yarn 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 yarn 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 yarns 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 yarns 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 yarns 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 yarns extending parallel to at least the first longitudinal edge, and a plurality of filling yarns 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 yarns are interlaced with the plurality of filling yarns 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 yarns each having a denier per filament of less than or equal to 0.01, and a second plurality of warp yarns extending parallel to at least the first longitudinal edge, and a plurality of filling yarns extending generally perpendicular to at least the first longitudinal edge, wherein 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 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 yarns extending parallel to at least the first longitudinal edge, and a plurality of filling yarns extending generally perpendicular to at least the first longitudinal edge, wherein 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 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.
The term “yarn” as used herein may comprise any type of filament yarn such as a monofilament yarn or a multi-filament yarn that forms a continuous strand. The term yarn may also mean an assemblage of fibers twisted or laid together so as to form a continuous strand. The yarns may comprise synthetic yarns such as PET yarns, polyamide (e.g., nylon) yarns, and/or elastic yarns and may also comprise natural yarns 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 structure in which a warp yarn is threaded over a first weft yarn, under an adjacent second weft yarn, and over an adjacent third weft yarn. 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 yarn”) as used herein refers to a yarn that is perpendicular to the selvage of the woven fabric and that is interlaced with warp yarns.
Continuing, the components of a woven trim piece comprise warp yarns and filling (or weft) yarns, where the warp yarns extend in the lengthwise direction of the trim piece and the filling yarns 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.

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”).

Continuing, the non-grip yarns 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 yarn, such as PET or polyamide yarns. In one exemplary aspect, the non-grip yarns 108 comprise an air-jet-spun 150 denier/144 filament PET yarn. Use of air-jet-spun yarns contributes to a softer feel or hand. Also depicted in

A functional benefit achieved by having a greater percentage of the grip yarns 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 D1894.2001 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 yarns having a high number of filaments per yarn strand, enabling the grip yarn to trap a larger volume of water between the filaments as compared to yarns 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 yarn to trap more moisture than a non-grip yarn, 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 yarn 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 yarn floats oriented perpendicular to this gravitational force, the gripping function of the grip yarns 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 true 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.

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 yarns 108 from, for example, PET or polyamide. These yarns typically absorb less moisture than, for example, cotton yarns and thus dry quicker. For instance, the moisture regain for textiles formed from PET yarns is around 0.4% and the moisture regain for textiles formed from polyamide yarns 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 yarns 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 yarn floats facilitate the spread of the moisture over the second face 104.

Continuing, the non-grip yarn 108 is woven in the inverse pattern such that the non-grip yarn floats are positioned on the second face 104 of the trim piece. To describe differently, after the grip yarn 106 and the non-grip yarn 108 are “floated” over three adjacent filling yarns 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 yarn 108.
It is contemplated herein that the trim piece 100 may comprise one or more elastic yarns (yarns 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 yarn that is covered with a PET yarn. In order to provide circumferential tensioning of the trim piece 100 when the trim piece 100 is in the form of a waistband, underband, and the like, the elastic yarns may be positioned in the warp such that they extend the length of the trim piece 100.

As stated above, it is contemplated herein that the grip yarns 106 and the non-grip yarns 108 may be floated over more than three filling yarns. An example of this is shown in

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 yarns 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 yarns 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.
