Dynamic ventilation structure for clothing

Abstract

An aspect of the invention is a composite laminate having a substrate layer (e.g., knit, woven, nonwoven, etc.) and a film layer secured or bonded to the substrate layer. The film layer, with a plurality of slits extending through both the substrate layer and the film layer, is formed of a material that changes dimensions when exposed to an external stimulus, such as moisture. When exposed to moisture, the film layer swells such that flaps formed by the plurality of slits extend from the film layer in the z-direction. The openings in the flaps form a through passage through the thickness of the composite structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0059] The subject matter of the present invention is described in detail herein to meet legal requirements. However, the description itself is not intended to limit the scope of the disclosure. Rather, the inventors contemplate that the claimed or disclosed subject matter may be embodied in other ways in combination with other current or future technologies to include different steps or combinations of steps similar to those described herein. Additionally, the terms "step" and / or "block" may be used herein to suggest different elements of the method used, but should not be construed as suggesting any particular order between the steps disclosed herein, unless the order of the individual steps is explicitly stated.

[0060] Ventilated structures in conventional apparel generally exist as static structures, either mechanical structures that require human operation, such as opening and closing through the use of a zipper or fastener, passively opening and closing in response to air entering and exiting the vent structure, or permanently open.

[0061] Aspects herein provide a ventilation structure that dynamically (e.g., with or without manual manipulation) transitions from a closed state to an open state in response to exposure to an external stimulus, such as moisture in the form of sweat. When the external stimulus is removed, the ventilation structure dynamically returns to the closed state. This allows for needed ventilation, for example, when the wearer is exercising, and allows for reduced ventilation when the wearer is resting without manipulation of the ventilation structure.

[0062] In an exemplary embodiment, the ventilation structure is adapted to be applied or secured to an article of clothing.

[0063] The textile may be in the form of a trim piece or a composite textile (e.g., a textile panel). The trim piece includes a composite structure, which may be a laminate having a substrate layer, which may include a knitted, nonwoven, or woven material, and a film layer secured or bonded to the substrate layer. One or more slits penetrate both the substrate layer and the film layer. The film layer is formed of a material that changes dimensions when exposed to an external stimulus, such as moisture. In an exemplary embodiment, the film layer expands and a flap formed by the one or more slits extends from the film layer in the Z direction. When the flap opens, a through passage is formed through the thickness of the composite structure. Water vapor and / or heat generated by the wearer dissipates through the through passage, and air from the external environment passes through the composite structure through the through passage to further aid in cooling the wearer.

[0064] In an exemplary embodiment, an optional support layer is secured to the composite structure, with a first surface of the support layer in flush relationship with the film layer. The support layer can provide structural support to the trim piece. In an exemplary embodiment, the support layer can be a mesh material or a spacer mesh material that is air and / or water vapor permeable. In other exemplary embodiments, the support layer can be a fleece material to provide warmth and / or thermal insulation functionality to the trim piece. In this example, the fleece is not as inherently air and / or water vapor permeable as the mesh material or the spacer mesh material, so the fleece material can include one or more openings axially aligned with at least a portion of the plurality of slits formed through the composite structure. Thus, when the flap(s) formed by the slits open, air and / or water vapor can travel through the openings in the fleece material and the through passages in the composite structure.

[0065] In an exemplary embodiment, the trim piece may be incorporated into a support garment, such as a brassiere, including a sports bra. For example, the trim piece may form an underband portion of the brassiere and be configured to extend around the wearer's torso. In this example, the support layer may be a lightweight mesh or spacer mesh material. The support layer is positioned adjacent to the wearer's skin surface, the substrate layer faces outward or externally, and the film layer is positioned between the support layer and the substrate layer. When the wearer begins to exercise and sweat, sweat and / or water vapor passes through the mesh or spacer mesh material and contacts the film layer. The film layer expands, and the flap formed by the one or more slits extends outwardly away from the support layer. The resulting through passages facilitate the transfer of water vapor and / or heat from the wearer's body to the external environment, aiding in cooling the wearer. When the wearer finishes exercising, the film layer returns to a resting state and the flap closes.

[0066] In an exemplary embodiment, the trim piece may be incorporated into an upper body garment, including an upper body garment designed to be worn in a variety of weather conditions, including precipitation (e.g., rain, snow, etc.), cold, and / or all-weather conditions. In this example, the upper body garment includes a baffle filled with an insulating filler to provide warmth to the upper body garment. The trim piece may be disposed between one or more adjacent baffles. In this example, the support layer is a fleece material that provides additional warmth to the upper body garment, the fleece material including openings that are axially aligned with the multiple slits formed through the composite structure. In an exemplary embodiment, the substrate layer may be a tightly woven material to provide wind resistance. In an exemplary embodiment, a durable water repellent may be applied to the substrate layer to provide water repellency to the trim piece. As described above, the support layer is disposed adjacent to the wearer's skin surface, the substrate layer faces outward or exterior, and the film layer is disposed between the support layer and the substrate layer. When the wearer sweats or produces water vapor, the sweat or water vapor passes through the openings in the fleece material and comes into contact with the film layer. The film layer expands, causing the flaps formed by the multiple slits to extend outward, away from the support layer. The resulting through passages facilitate the transfer of water vapor and / or heat from the wearer's body to the external environment, helping to cool the wearer. When the wearer rests and is no longer sweating and / or producing water vapor, the flaps close, retaining heat and increasing the wearer's warmth.

[0067] In an exemplary embodiment, the cover piece may be disposed outside the trim piece and adapted to partially or completely cover the trim piece with the plurality of slits. The cover piece may prevent precipitation from the external environment from entering an article incorporating the trim piece through the plurality of slits. When the trim piece flap is opened, the flap mechanically pushes the cover piece outward, so that the cover piece does not impede the movement of air or water vapor through the passageway and prevents precipitation from the external environment from entering the article through the passageway.

[0068] As an example, the composite structure (including the film, substrate, and support layer) can be incorporated into one or more panels of a garment, such as the upper back portion of a jacket. In this example, the jacket may be formed of a multi-layer structure and include an outer layer that acts as a cover for the composite panel. The outer layer is designed with drape characteristics to act as a shield to prevent precipitation or other environmental elements from entering the jacket through passages in the panel, while fitting loosely enough to allow flaps in the composite panel to open and allow ventilation.

[0069] The term "article" or "apparel" as used herein includes any product intended to be worn by a wearer, such as upper body garments (such as shirts, jackets, hoodies, pullovers, etc.), lower body garments (such as pants, shorts, leggings, etc.), footwear such as shoes and socks, headwear (such as hats), gloves, sleeves (such as arm sleeves, calf sleeves, etc.). The positional terms used when describing an article of clothing, such as front, back, inner surface, outer surface, top, bottom, proximal, distal, medial, lateral, etc., refer to the article of clothing as intended to be worn by the wearer in an upright position. Thus, when the article of clothing is in the form of an upper body garment or lower body garment, the front of the article of clothing is configured to cover, for example, the front torso region, forearm region, or fore-limb region of the wearer, and the rear of the article of clothing is configured to cover the rear torso region, rear arm region, or rear-limb region of the wearer. Similarly, the inner surface of the garment is configured to be placed adjacent to the wearer's skin surface or base layer, and the outer surface of the garment is configured to face the external environment. The term "innermost surface" refers to the layer of the article that is positioned closest to the wearer's skin surface relative to the other layers of the article, and the term "outermost surface" refers to the layer of the article that is positioned furthest from the wearer's skin surface relative to the other layers of the article.

[0070] The term "trim piece" as used herein means a structure adapted to be applied to a garment in forming the garment. The trim piece may be in the form of a strip having a length generally greater than the strip width. The trim piece may be in different shapes such as a panel. Any and all embodiments and any variations thereof are contemplated as being within the scope of this specification.

[0071] As used herein, the term "Z-direction" refers to a direction extending positively or negatively from the surface of the trim piece and / or garment. The terms "X-direction" and "Y-direction" refer to directions extending along the surface of the trim piece and / or garment.

[0072] As used herein, the term "dimensional change" refers to a change or modification in one or more dimensions, such as an X-direction or axis, a Y-direction or axis, and / or a Z-direction or axis. For example, an object may undergo a dimensional change by expanding, contracting, folding, bending, curling, lifting, relaxing, and / or straightening along its length, width, and / or height.

[0073] The term "axially aligned" as used herein means that the axis of a feature is parallel or collinear with the axis of another feature, as that term is understood in the art.

[0074] As used herein, the term "external stimulus" encompasses any number of stimuli, such as temperature, pressure, moisture, electrical energy, magnetic energy, light, sound, etc. In one embodiment, the external stimulus is moisture, which can be in the form of liquid water, water or water vapor, sweat, etc.

[0075] As used herein, the term "throughway" refers to an opening formed in a trim piece and / or garment that provides a communication path for fluids (such as vapors, gases, liquids, etc.) between the external environment and the interior of the garment (the space between the inner surface of the garment and the wearer's body). The terms "dynamic" or "dynamically," when used to describe a vent structure transitioning from a closed to an open state, or vice versa, generally refer to a self-generated mechanical action that occurs without human manipulation or operation of the vent structure.

[0076] As used herein, the term "composite material" means a material that includes two or more constituent materials that may have different properties and that, when combined, create a material that has properties that differ from those of the individual materials.

[0077] As used herein, the term "laminate" refers to a structure in which at least two layers are bonded together (e.g., two or more layers of the same or different materials). Bonding of the layers may be accomplished in a variety of ways, such as with chemical adhesives, ultrasonic welding, thermal bonding, mechanical fastening (e.g., stitching), or other known techniques. In some instances, a laminate may include a composite material, or vice versa.

[0078] In an exemplary embodiment, the "film layer" described herein may include a thermoplastic material, and may include one or more of a thermoplastic polymer material and a thermoplastic elastomer material. For example, the film layer may include a thermoplastic polyester elastomer (TPEE). In an exemplary embodiment, the film layer may include a hygroscopic material embedded in or mixed with the thermoplastic material. For example, a TPEE film layer may include polyethylene glycol, sodium polyacrylate, and the like. Due to the presence of the hygroscopic material, the film layer expands in one or more of the z-direction, x-direction, and y-direction when exposed to moisture.

[0079] The term "mesh material" as used herein means any textile with a permeable texture. The permeable texture may be imparted by loose weaving, loose knitting, perforating the textile, etc. The resulting textile has many holes per inch and is highly permeable to air. The term "spacer mesh material" as used herein means a material (knitted or woven) in which the top and back layers are connected by threads that run in a direction approximately perpendicular to the top and back layers. The term "fleece material" as used generally means a textile with a brushed surface that provides excellent thermal insulation.

[0080] Unless otherwise noted, all measurements provided herein are with the trim pieces and / or apparel items unworn and at rest, and at standard ambient temperatures and pressures.

[0081] FIG. 1 is a perspective view of a first surface 110 of a portion of a trim piece 100. In some examples, the trim piece 100 can be configured as a multi-layer composite textile of different materials in roll or sheet form. Additionally, a portion can be cut from the trim piece 100 and incorporated into an article of clothing. For example, a portion cut from the trim piece 100 can be applied along an edge, an opening, a cuff, etc. Additionally, a portion can be applied to another panel or portion of an article of clothing. In some examples, a portion can form a wall or panel of an article of clothing (e.g., not necessarily overlapping another textile panel). In some examples, the trim piece 100 can include a textile (e.g., a multi-layer composite textile).

[0082] The trim piece 100 includes a composite structure 112 including a substrate layer 114 and a film layer 116 secured to a first surface of the substrate layer 114 (better seen in FIG. 2). An opposite second side 118 of the substrate layer 114 forms the first side 110 of the trim piece 100. The substrate layer 114, in exemplary embodiments, may include a knitted structure, a woven structure, a nonwoven structure, a braided structure, or the like. In some exemplary embodiments, the substrate layer 114 may include one or more coatings or finishes, such as a durable water repellent finish, applied to the opposite second side 118. In exemplary embodiments, the entirety of the film layer 116 (i.e., the entire surface) is secured to the substrate layer 114 by bonding. For example, the film layer 116 may be secured to the substrate layer 114 by melting such that the film layer 116 penetrates or at least partially penetrates at least the first surface of the substrate layer 114. Other methods of securing the film layer 116 to the substrate layer 114 are contemplated herein, including using adhesives, point bonding, and the like. In some exemplary embodiments, the film layer has a uniform thickness. In other exemplary embodiments, the film layer 116 may have one or more gaps in a uniform, gradient, or random pattern. In yet another exemplary embodiment, the film layer 116 may include a plurality of individual nodes secured to the substrate layer 114. The nodes may be located at the same location along the substrate layer 114, for example, with one or more slits as described herein (e.g., a circular, oval, square, rectangular, etc. node of the film may at least partially overlap with the slit(s)).

[0083] The plurality of slits 120 extend through the thickness of the composite structure 112. In an exemplary embodiment, the plurality of slits 120 may include a pattern having a first linear slit 121 and a second linear slit 123 that bisects or intersects the first linear slit 121 to form a "plus" shape. Other exemplary shapes are contemplated herein, including a single slit, other patterns or shapes of two slits intersecting each other, and / or other patterns or shapes of two or more slits intersecting each other. In examples, the slits may be straight, bent, or curved. In examples, the slits extending through the thickness of the composite material associate with (e.g., form) an edge of a portion of the composite material, and a flap (e.g., multiple flaps) is formed as a result of the slits. In at least some examples, when the film layer 116 is exposed to moisture, the edge of the flap lifts or curls from the slit and / or the intersection of the multiple slits, as described below and shown in FIG. 3. 1 are for illustrative purposes only, and other spacing arrangements and different numbers of slits are contemplated and within the scope of the present specification. The stiffness of the substrate 114, and the introduction of areas and / or lines of strength or weakness (e.g., reinforcing ribs or scorelines) in the substrate 114, may change the curling nature of the flap 310, or may cause the flap to fold along the hinge at its base and appear to curl significantly along its length.

[0084] 1-3 show some examples of slit configurations. In various examples, the slits 120 can include various configurations. For example, FIG. 17 shows some other slit "shapes" illustrating various configurations that can be used. For example, as shown in FIGS. 17A-B, one or more slits 120 connect only at one end of the slits 120 to form a "T" or "L" shape (or an "I" or "H" shape - not shown). In at least some examples, as shown in FIGS. 17C-E, the slit configurations include ear or tab shapes, which can be formed by a single curved slit 120 (e.g., C-shaped or S-shaped) or can include multiple slits 120 end to end in different directions. FIGS. 17F-H show shapes formed by three, four, or five slits 120 crossing or connecting to form a "star" pattern. FIGS. 17I-J show other configurations, such as X-shaped or Y-shaped. Even in these examples, the flaps formed by one or more slits 120 can change dimensions when exposed to moisture or other external stimuli. In at least some examples, the slit configuration includes a single linear slit 120 (e.g., FIG. 17K), where at least one edge on either side of the slit 120 (e.g., the portion of the composite structure associated with that edge) changes dimension, such as by wrinkling or gapping, when the film layer 116 is exposed to a stimulus (e.g., moisture). In the above examples, the slit 120 may be formed in the example composite structure 112 shown in FIG. 1, which has a substrate layer 114 and a film layer 116, or any other composite structure described in or equivalent to the subject matter of this disclosure.

[0085] The spacing between the slit features may be determined based on a balance of several factors, including durability and the amount of airflow desired. For example, narrower spacing between slits may maximize the amount of airflow per area, but may increase the fragility of the composite structure 112. In an exemplary embodiment, the spacing between slits may be between 0.2 inches and 0.5 inches.

[0086] The plurality of slits 120 can be formed using a variety of techniques. For example, in some instances, the plurality of slits can be formed by cutting slits in the composite structure 112 using a laser or other heating tool. In some cases, heat from a laser or other heating tool can at least partially soften (e.g., melt) one or more of the film layer 116 and / or substrate layer 114, and when the layer(s) reharden, the film layer 116 and substrate layer 114 can be at least partially bonded (e.g., cauterized) along their edges. The plurality of slits 120 can be formed using one or more other techniques, such as a die, stamp, blade, etc.

[0087] The trim piece 100 optionally includes a support layer 122, which may be in flush relationship with the film layer 116. As used herein, the term "flush relationship" means that the plane of the film layer is in contact, near contact, or at least flush with the plane of the support layer (e.g., with no intervening structure therebetween). The support layer 122 can operate in a variety of ways to provide one or more different functions. The support layer 122 may operate in a variety of ways to provide one or more different functions. In some examples, the support layer 122 may be configured to provide a wearer-facing surface. As previously discussed, the support layer 122 may include a mesh material, a spacer mesh material, a fleece material having openings, and the like.

[0088] FIG. 2 illustrates a cross-section of the trim piece 100 at section line 2-2, where section line 2-2 is aligned along an axis of a portion of the plurality of slits 120. FIG. 2 illustrates a film layer 116 secured to a first surface 210 of a substrate layer 114. In some examples, the film layer 116 and the substrate layer 114 comprise a composite structure 112. In at least some examples, the film layer 116 is a separate layer that is applied to a surface of the substrate layer 114. In at least some examples, the film layer 116 may be at least partially incorporated into the substrate layer 114, for example, by melting. In some cases, the extent to which the film layer 116 is incorporated into the substrate layer 114 may affect the swelling time and / or reset time associated with the composite material 112. For example, a composite material 112 in which the film layer 116 is less integrated into the substrate layer 114 (e.g., when the film layer 116 is applied to a surface) may behave differently than a composite material 112 in which the film layer 116 is more integrated into the substrate layer 114 (e.g., when the film layer 116 is at least partially melted). Thus, in some cases, the degree to which the film layer 116 penetrates the substrate layer 114 can be controlled to achieve a desired effect. The slit 120 can include a variety of dimensions. For example, in some cases, the slit 120 includes a length 121 that ranges from 1 / 8 inch to 5 / 8 inch. In some examples, the length 121 is 0.5 inch.

[0089] In an exemplary embodiment, the support layer 122 is secured to the composite structure 112 along one or more perimeter edges of the support layer 122. In one example, the support layer 122 may be secured to the composite structure 112 by stitching, as shown by stitch 212, although other securing techniques are contemplated herein, including bonding, adhesives, and the like. In this example, a potential space 214 may be formed between the support layer 122 and a portion of the composite structure 112. The embodiments herein also contemplate the support layer 122 being secured to the composite structure 112 at an area inward of the perimeter of the support layer 122. Any and all embodiments and variations thereof are contemplated for inclusion in each embodiment of the present application.

[0090] FIG. 3 illustrates a perspective view of a first surface 110 of a portion of the trim piece 100 of FIG. 1 after the trim piece 100 has been exposed to an external stimulus. In an exemplary embodiment, the external stimulus may be moisture, for example in the form of sweat and / or water vapor generated by a wearer. The sweat and / or water vapor contacts the film layer 116 and causes the film layer 116 to dimensionally deform, such as by expanding in one or more of the x-direction, y-direction, and / or z-direction. The dimensional change in the film layer 116 causes a flap 310 formed by the plurality of slits 120 to extend in the Z-direction away from the support layer 122. More specifically, at least an apex, e.g., apex 312, of the flap 310 curls away from the intersection of the slits 120. The curling of the flap 310 forms a passageway, e.g., passageway 314, through the thickness of the composite structure 112. When the film layer 116 is exposed to moisture, the flap 310 changes dimensions, and the passageway 314 may further increase in size. An increase in size of the through passage 314 can be determined based on an increase in the distance between two points on opposite sides of the through passage 314. In some examples, an increase in the saturation rate of the film layer 116 may decrease the rate of expansion of the film layer 116. For example, when the film layer 116 reaches maximum saturation, the expansion associated with the film layer 116 may slow or stop.

[0091] As previously discussed, exposure of the film layer 116 to moisture may cause the flap 310 to deform dimensionally, increasing the size of the through passages 314. In some instances, the increased size of the through passages 314 may allow additional airflow to pass from one side of the composite structure 112 to the other. The increased airflow may improve the breathability or cooling effect of a garment including the composite structure 112. Conversely, removal of moisture from the film layer 116 may cause the through passages 314 to decrease in size, restricting airflow between the sides of the composite structure 112.

[0092] When film layer 116 is no longer exposed to sweat or water vapor, moisture is removed from the film layer (such as by evaporation) and flaps 310 transition to the closed state as shown in Figure 1, causing film layer 116 to return to its resting state (i.e., decrease in dimension in one or more of the x-, y-, and / or z-directions), in which the flaps 310 are generally planar relative to one another.

[0093] In examples, the operation of the flaps 310 (e.g., the speed at which they open and close, the extent to which they open) can depend on a variety of factors. In some examples, the operation can depend, at least in part, on the amount and nature of moisture contacting the film layer, or conversely, on the intensity of an external stimulus, such as the evaporation rate. Additionally, different configurations of the flaps (e.g., the number and size of the flaps) can affect the absorption / evaporation rate. For example, smaller flaps may involve a smaller surface area (compared to larger flaps), which means less moisture needs to evaporate, resulting in shorter retransmission times (e.g., relaxing, de-curling, straightening, etc.). Based on this, a plus sign slit configuration (e.g., two intersecting slits) may, in some cases, reset slower than a star shaped slit configuration with three intersecting slits, and the slit configurations can be adjusted to provide faster or slower reset times for different applications.

[0094] Additionally, the behavior of the flaps 310 will vary depending on the configuration and properties of the substrate layer 114 and the thickness and orientation of the film layer 116. For example, the film layer 116 may tend to expand more rapidly or to a greater extent in one or more of the x-, y-, and / or z-directions depending on how it is manufactured. For example, in a film manufactured by blow extrusion, the alignment of crystalline structures within the film may cause the film to be configured to expand more in the weft or transverse direction (perpendicular to the extrusion direction) than in the machine direction (parallel to the extrusion direction). In an exemplary embodiment, the orientation of such film layer 116 relative to the orientation of the plurality of slits 120 may affect the nature, shape, rate, and / or degree of curling of the various flaps 310 when the film layer is exposed to an external stimulus. For example, as shown in Figures 18A-18D, when the "plus" slits are oriented such that one of the slits 120 is parallel to the machine direction of the film with greater lateral expansion (Figure 18A), the flaps 320 tend to open more uniformly (Figure 18C) than when the slits 120 are oriented at a 45 degree angle to the machine and cross directions (Figures 18B and 18D). In the latter situation, the flap opening in the cross direction 320A often curls more or curls faster than the flap opening in the machine direction 320B. In another example shown in Figures 19A-19D, a single slit 120 parallel to the machine direction of the film layer (Figure 19A) often exhibits more wrinkling (Figure 19C) than a slit 120 parallel to the cross direction of the film (Figures 19B and 19D). In at least some examples, the slit 120 is oriented in a direction that is not parallel to the cross direction of the film layer 116 (greater than 0 degrees and less than 180 degrees). The properties of the film 116 and substrate layer 114 may also be selected such that opening of the flap 310 is delayed until a certain amount of external stimulus (e.g., moisture) is reached. This may be accomplished, for example, by selecting the substrate layer 114 with a sufficient level of stiffness to initially resist bending due to the initial expansion of the film layer 116. In the above example, the slit 120 may be formed in the example composite structure 112 of FIG. 1 having the substrate layer 114 and film layer 116, or in any other composite structure described or equivalent in the subject matter of this disclosure.

[0095] There are several different ways to determine if a film layer exhibits greater expansion in one or more dimensions, which would suggest which direction is the machine direction and which direction is the transverse direction (e.g., of the film layer). For example, a reference line can be marked on the composite, and then a sample can be cut from the composite such that the swatch or sample contains a first segment of the reference line and a second segment remains on the composite. Moisture is then applied to the sample and the sample is observed to determine in which direction the sample curls. Note that the machine direction of the curled portion is generally aligned with the machine direction, so it can be noted (e.g., marked) and the machine direction of the composite can be determined by aligning the first segment with the second segment.

[0096] FIG. 4 illustrates a first example of the opposite second surface 410 of the trim piece 100, the second surface 410 being formed from a support layer 122. The support layer 122 is shown as being secured to the composite structure 112 by a fastening region 412 (e.g., stitches, adhesive, bond points) that extends along the periphery of the support layer 122, although in other exemplary embodiments, the fastening region may be provided at one or more portions of the support layer 122 other than the periphery. In exemplary embodiments, the plurality of slits 120 do not extend through the support layer 122. In the example illustrated in FIG. 4, the support layer 122 is formed from a mesh material or spacer mesh material, as shown in the close-up view showing the openings or apertures 414. The structure illustrated in FIG. 4 may be useful for lightweight athletic apparel such as bras, tights, support tanks or tops, etc.

[0097] FIG. 5 illustrates a second example of the opposite second surface 510 of the trim piece 100, where the second surface 510 is formed from a support layer 122. The support layer 122 is shown secured to the composite structure 112 by a fastening region 512 (e.g., stitches, adhesive, bond points) extending along the periphery of the support layer 122. In an exemplary embodiment, the plurality of slits 120 do not penetrate the support layer 122. In the example illustrated in FIG. 5, the support layer 122 is formed from a fleece material. The support layer 122 includes a plurality of openings 514 axially aligned with the plurality of slits 120. This is because, unlike mesh or spacer mesh materials, which are inherently permeable in structure, fleece is not very permeable. The axial alignment of the plurality of slits 120 and the plurality of openings 514 facilitates sweat and / or water vapor contact with the film layer 116. The structure illustrated in FIG. 5 may be useful for insulated clothing items such as jackets, coats, midlayers, etc.

[0098] Figure 6 is a cross-sectional view of the trim piece 100 taken along section line 6-6 of Figure 5. Figure 6 is provided to illustrate the axial alignment of the slits 120 in the composite structure 112 with the openings 514 in the support layer 122. For example, the slits 120 are aligned with the openings 514 along an axis 610.

[0099] 7 and 8 illustrate a first example of use of the trim piece 100 in the form of a bra 700. FIG. 7 illustrates the bra 700 before exposure to an external stimulus, and FIG. 8 illustrates the bra 700 after exposure to the external stimulus. The depiction of the bra 700 is exemplary, and it is contemplated herein that the bra 700 may include configurations other than those illustrated. The bra 700 includes a front portion 710 including a first chest-covering portion 712 and a second chest-covering portion 714, each configured to cover a right and left breast of a wearer, respectively. A shoulder strap 716 extends from an upper margin of the front portion 710 and is configured to extend over the shoulders of the wearer. An underband 718 extends from a lower margin of the front portion 710 and is configured to encircle a torso region of the wearer.

[0100] In the exemplary embodiment, the underband 718 is a trim piece 100 having a plurality of slits 120. The substrate layer 114 forms the outer surface of the underband 718 and the support layer 122 forms the inner surface of the underband 718 (not shown). In the exemplary embodiment, the substrate layer 114 may comprise a lightweight knit or woven material suitable for use in athletic apparel and the support layer 122 may comprise a mesh material or a spacer mesh material that further contributes to the lightweight functionality of the bra 700. The plurality of slits 120 are shown extending along the length of the underband 718.

[0101] 8 shows the underband 718 after being exposed to moisture in the form of sweat and / or water vapor generated by the wearer. The moisture passes through the support layer 122 and contacts the film layer 116, causing the film layer 116 to expand or change dimensions. The flaps 310 curl outward from the inner surface of the underband 718 to form through passages 314, which facilitate dissipation of heat and / or water vapor generated by the wearer and aid in cooling the wearer. When the wearer is not sweating, the film layer 116 returns to its unexpanded state and the flaps 310 close.

[0102] 9 illustrates a second example of the use of trim piece 100 in the form of an upper body garment 900. Although shown as a vest, it is contemplated herein that the article may include any type of upper body garment, such as a jacket, coat, hoodie, pullover, etc. Upper body garment 900 includes a front torso section 910 and a back torso section (not shown) that together define a neck opening 912, a waist opening 914, and arm openings 916.

[0103] The upper body garment 900, in an exemplary embodiment, includes a plurality of baffles 918 that contain insulating filler material, such as down, loose synthetic fibers, nonwoven sheets, etc. An example of a baffle is shown in Figure 1. It is shown in Figure 10 and designated by reference numeral 1000. The baffle 1000 includes an outer layer 1010 and an inner layer 1012 that define a chamber or pocket 1014 that contains insulating filler material 1016.

[0104] The upper body garment 900 further includes a plurality of trim pieces 920 disposed between adjacent baffles 918, with each trim piece 920 spacing adjacent baffles 918 apart. The trim pieces 920 may be secured to the baffles 918 by various fastening techniques, such as stitching, bonding, adhesives, and the like. The trim pieces 920 may be trim pieces 100 having a substrate layer 114, a film layer 116 secured to the substrate layer 114, and a support layer 122. Although the trim pieces 920 are shown in FIG. 9 as being disposed between adjacent baffles 918, it is contemplated herein that the trim pieces 920 may be disposed at discrete locations on the clothing item 900. For example, the trim pieces 920 are primarily disposed in the front upper chest region and the upper back region of the garment 900. When the garment 900 is worn by a wearer, these regions may correspond to high heat and / or sweating regions of the wearer based on a thermal and sweating map of the human body.

[0105] 9 shows upper body garment 900 prior to exposure to an external stimulus, with multiple slits 120 closed to help retain heat. In an exemplary embodiment, to provide additional warmth and / or insulating properties to upper body garment 900, support layer 122 may be formed from a fleece material having openings, as shown in FIG.

[0106] FIG. 11 illustrates the upper body garment 900 after exposure to an external stimulus in the form of, for example, sweat and / or water vapor generated by the wearer. The sweat and / or water vapor passes through the openings in the support layer 122 and contacts the film layer 116, causing it to expand and the flaps 310 to extend outward from the support layer 122 to form through passages 314 through which the water vapor dissipates. In an exemplary embodiment, depending on where the sweat or water vapor is generated, only some of the flaps 310 may open while others remain closed. For example, as shown in FIG. 11, the trim pieces 920 in the upper chest region of the upper body garment 900 may be exposed to more water vapor and / or sweating as this region corresponds to the high heat and / or sweating region of the wearer. Thus, the flaps 310 in this region will open and the flaps 310 near the waist opening 914 will remain closed, helping to retain more warmth / heat in this region. The result is dynamic, customized ventilation based on the wearer's individual sweat and moisture production.

[0107] 9 and 11 show an upper body garment, embodiments herein contemplate other uses of trim piece 100. For example, trim piece 100 may form a waistband and / or cuff of an upper body garment, or a waistband and / or cuff of a lower body garment. Trim piece 100 may also be inserted as a panel into an upper body garment or a lower body garment to provide breathability in desired areas of the respective garment. Any and all embodiments and any variations thereof are contemplated as being within the scope of the present specification.

[0108] 12-14 illustrate example configurations that may be optionally used, for example, with respect to the upper body garment 900 or any of the other garments or articles described herein. FIG. 12 illustrates a perspective cross-sectional view of a portion of the upper body garment 900 before the trim piece 920 is exposed to an external stimulus. FIG. 12 illustrates two adjacent baffles 918a and 918b separated by the trim piece 920. The cover piece 1210 includes a first linear edge 1212 that is secured or assembled to the baffle 918a using a fastening technique such as stitching, bonding, adhesives, or the like. An opposing second linear edge 1214 is not secured or assembled to the upper body garment 900. The second linear edge 1214 extends along the longitudinal length of the trim piece 920.

[0109] The cover piece 1210, in an exemplary embodiment, may be formed of a tightly woven material that is resistant to water and / or wind penetration. The cover piece 1210 may optionally be treated with a durable water repellent to provide enhanced water resistance functionality. The cover piece 1210, and more specifically, the second linear edge 1214, is positioned to partially or completely cover or cover the trim piece 920 that includes the multiple slits 120. This prevents moisture or precipitation from the external environment from entering the upper body garment 900 through the slits 120.

[0110] A side view of this structure is shown in Figure 13. The trim piece 920 is not exposed to external stimuli, so the flap 310 is lying flat. The second straight edge 1214 of the cover piece 1210 covers the outer surface of the trim piece 920, and the first straight edge 1212 is shown secured to the baffle 918a.

[0111] Another side view of this structure after the trim piece 920 has been exposed to moisture, such as sweat or water vapor from the wearer, is shown in Figure 14. The flap 310 is shown extended outwardly. The flap 310 mechanically pushes the cover piece 1210 outwardly so that the cover piece 1210 does not impede the movement of air or water vapor through the passageway 314 while at the same time preventing precipitation from the external environment from entering the upper body garment 900 through the passageway 314. The cover piece may be sized and configured such that the second linear edge continues to cover the trim piece while the flap 310 is in the extended position.

[0112] 15 illustrates a flow diagram of a method 1500 of forming a trim piece, such as trim piece 100 for use in a garment. In step 1510, a plurality of slits, such as slits 120, are formed in a thickness of a composite structure, such as composite structure 112 of trim piece 100. The composite structure includes a substrate layer, such as substrate layer 114, and a film layer, such as film layer 116, secured to a first surface of the substrate layer. The film layer is formed of a material that changes dimensions when exposed to moisture. For example, the film layer may expand when exposed to moisture.

[0113] In step 1512, a support layer, such as support layer 122, is secured to the composite structure such that a first surface of the support layer is in flush relationship with the film layer. In an exemplary embodiment, the support layer may include a mesh material, a spacer mesh material, or other material having high breathability. In other exemplary embodiments, the support layer may be formed from a fleece material having axially aligned openings with a plurality of slits formed through the composite structure.

[0114] As indicated above, in some examples, the composite material including the film layer and the substrate layer can be incorporated into panels or portions of various types of garments. For example, with reference to FIGS. 16A-16C, the composite material can be incorporated into an upper body garment 1610 (e.g., a jacket, a windbreaker, etc.), such as an upper back portion of the upper body garment 1610. In some examples, the upper body garment 1610 can include a multi-layer structure including an outer layer 1612. Further, as shown in the cross-sectional views of FIGS. 16B and 16C (e.g., with a portion of the outer layer 1612 cut away), a composite layer panel 1614 including a film layer and a substrate layer can be disposed below the outer layer 1612. The film layer and substrate layer can include all of the features described throughout this disclosure. In some examples, the upper body garment 1610 can include a mesh layer or other inner lining below the composite layer panel 1614 (e.g., between the composite layer panel 1614 and the wearer when the upper body garment 1610 is worn).

[0115] In some examples, the outer layer 1612 can include a bottom edge 1616 that extends below the bottom row of slits 1618 (e.g., the bottom edge 1616 is positioned further from the collar of the upper body garment 1610 and closer to the hem of the upper body garment 1610 than the bottom row of slits 1618). Thus, the outer layer 1612 can, in some cases, reduce the likelihood that precipitation (e.g., from the outside environment) or other environmental elements (e.g., debris) will enter the upper body garment 1610 via the through passages 1620. In at least some examples, the outer layer 1612 can be treated with a DWR (durable water repellent or other surface treatment), which can also help keep environmental elements away from the composite layer panel 1614.

[0116] In some examples, the outer layer 1612 is associated with drape characteristics such that the outer layer 1612 acts as an effective shield against environmental elements (e.g., by opening through passages 1620) while also allowing sufficient ventilation, i.e., the outer layer 1612 fits loosely enough over the composite layer panel 1614 to allow for an open flap that is exposed to the stimuli, as described in connection with the cover piece 1210 of FIG.

[0117] Aspects of the present disclosure are described for purposes of illustration, not limitation. Alternative aspects will be apparent to those skilled in the art that do not depart from its scope. Those skilled in the art may develop alternative means of implementing the improvements described above without departing from the scope of the present disclosure.

[0118] It will be understood that certain features and subcombinations are of utility and may be utilized without reference to other features and subcombinations and are contemplated within the scope of the claims. Not all of the steps described in the various figures need be performed in the particular order described.
