The present disclosure relates to zoned moisture management apparel for wear during exertion.
There are numerous challenges to designing apparel to effectively manage a wearer's perspiration and cooling during exertion. Different areas of a wearer's body perspire at varied rates and further, activity type may affect perspiration patterns. Apparel worn during exercise or activity may vary in contact areas with the wearer, which affects the cooling mechanism.
During exercise, playing sports, or other exertion, body perspiration evaporates in order to cool the body of a wearer. To complicate matters, a wearer's body perspires at different rates in different zones of the body and cooling via evaporation varies across the body. Perspiration zones also vary for men versus women. Optimizing apparel for moisture management may provide improved performance by tailoring the moisture management properties of different zones of the apparel. Zoned garments may be created by stitching together textile panels of different meshes or porosities; however, this requires introduction of bulky and uncomfortable seams and requires labor intensive stitching.
To this end, a zoned moisture management garment is provided by incorporating a denier differential fabric with aerographic yarn compositions and zoning. A denier differential mechanism may utilize morphological properties of fibers and textiles, to provide moisture management properties. Denier differential refers to yarn of different denier or thickness on the face versus the back of a textile. A moisture management fabric may be engineered with two sides: a facing layer and a back layer. Surface tension and capillary forces drive the moisture from the wearer's skin to the back layer. Moisture then moves from the back layer to the facing layer due to increased surface area of the facing layer. Due to the increased surface area of the facing layer, moisture may be spread out with greater surface area to evaporate. Aerographics generally refers to a method of using two yarn compositions: one that may be dissolvable in a given solvent and one that may not be dissolvable in the solvent. Dissolution of the dissolvable yarn may be confined to specific zones and provides a way to remove a portion of the fabric to increase air flow and porosity of the fabric. By incorporating a dissolvable yarn into the denier differential fabric, certain areas of an exemplary garment may be selected to be more ventilating while other areas or zones of the garment may be selected to promote skin-side dryness by moving moisture away from skin.
In one example of a garment in accordance with the present invention, a zoned moisture management garment is presented, comprising a first fabric layer and a second fabric layer adjacent to the first fabric layer. The second fabric layer may be the inner most layer or skin-side layer of the garment when the garment is worn. The first fabric layer may include a first non-dissolvable yarn of a first denier per filament between about 0.50 and about 1.04 or a microfiber and first dissolvable yarn of a second denier per filament between about 0.50 and 1.04 or a microfiber, wherein at least one zone of the first fabric layer may have the first dissolvable yarn dissolved. The second fabric layer may include a second non-dissolvable yarn of a third denier per filament greater than the first denier per filament, wherein the third denier per filament may be between about 1.04 and 3.50 or a macrofiber and a denier differential between the first denier per filament and the third denier per filament may be at least about 0.54.
An additional example of an exemplary zoned moisture management garment may include, in the second fabric layer, a second dissolvable yarn of a fourth denier per filament greater than the first denier per filament, wherein the fourth denier per filament may be between 1.04 and 3.50 or a macrofiber and a denier differential between the first denier per filament and the fourth denier per filament may be at least about 0.54 and wherein at least one zone of the second fabric layer may have the second dissolvable yarn dissolved. In one example of a zoned moisture management garment, the first non-dissolvable yarn may be synthetic and the second non-dissolvable yarn may be synthetic. In another exemplary zoned moisture management garment, the first non-dissolvable yarn may be polyester and the second non-dissolvable yarn may be polyester. The first fabric layer and the second fabric layer of an exemplary zoned moisture management garment may be constructed by knitting or weaving. In one example, the first fabric layer and the second fabric layer of a zoned moisture management garment may be circular double knit. Alternately, the first fabric layer and the second fabric layer may be circular, plaited single-knit. The first dissolvable yarn may comprise between about 10% and about 40% of the fabric of the zoned moisture management garment, such as 30% of the fabric of zoned moisture management garment.
Furthermore, at least one zone of the first fabric layer where the second dissolvable yarn is dissolved may be a zone pattern, logo, or shape. In another example, the at least one zone may be placed on the garment according to a sweat profile of an athlete to provide desired moisture management and/or cooling properties. In an example, where the garment may be a shirt having a shoulder area, a chest area, an upper back area, an abdomen area, an armpit area, and a lower back area, the at least one zone may be located at the shoulder area, armpit area, abdomen area, and lower back area. An exemplary zoned moisture management garment may further comprise an additional fabric layer including a third non-dissolvable yarn of a fourth denier per filament. The additional fabric layer may include a third dissolvable yarn of a fifth denier per filament and at least one zone of the additional fabric layer may have the second dissolvable yarn dissolved.
In another example of a garment in accordance with the present invention, a zoned moisture management garment may be provided comprising a first fabric layer and a second fabric layer adjacent to the first fabric layer, wherein the second fabric layer may be the skin-side layer or the inner most layer of the garment when the garment is worn.

In order to create a zoned moisture management garment, perspiration across the wearer's skin may be determined to provide a sweat profile, including areas of greatest perspiration such as the armpits or chest area. The sweat profile may vary from wearer to wearer and may differ greatly between men and women. For zoned garment optimization, areas of contact between the wearer and portions of the garment may be determined. In one example, the areas of contact may be overlaid with a sweat map to determine garment zoning. This information and other data regarding sweating profile during various sports activities may be used to determine the ideal zoning for a zoned moisture management garment. Sweat profiles and contact areas may also vary based upon the sport or exercise that the wearer is engaging.
A sweat profile and a contact map of the areas of contact between a garment and a wearer may provide a guide for the zone placement of the zoned moisture management fabric. In one instance, a contact map may be created by determining what areas of a garment contact the wearer more in certain areas, such as the shoulder area, than in the other areas of the garment, such as the abdomen area. In those contact areas, the garment may provide the most appropriate moisture management means using the denier differential wicking mechanism described in detail below. However, in the areas outside of contact areas, the wearer may also be perspiring. Due to the reduced contact of the garment to the wearer, ventilation may be the most appropriate means for sweat management. To introduce the ventilated areas or zones into a location of the garment, a dissolvable yarn comprising a portion of the zoned moisture management garment may be dissolved in the zones where increased porosity and ventilation are desired. The resultant zoned moisture management garment may provide a denier differential moisture management mechanism in contact areas and may also provide a ventilation moisture management mechanism in areas of less contact.

The first fabric layer 503 and the second fabric layer 502 may be constructed separately, by weaving or knitting, and assembled to form the fabric. In one example, the layer 503 and the second fabric layer 502 may be constructed continuously, by weaving or knitting, to form a seamless fabric. Any appropriate pattern or method of weaving or knitting may be employed, for example plain weaving, satin weaving, circular double knit, or circular plaited single knit. The second fabric layer 502 is the layer adjacent to the wearer's body 500 and the first fabric layer 503 is adjacent to the second fabric layer 502. The wearer's body 500 perspires and moisture may be adsorbed 504 from the body 500 surface to the first fabric layer 503. The denier differential, which is discussed in greater detail below, between the first fabric layer 503 and the second fabric layer 502, can provide a difference in porosity and surface area wherein the first fabric layer 503 may have a greater surface area and smaller pores than the second fabric layer 502. The smaller pores and greater surface area results in increased capillary force for aqueous solutions for the first fabric layer 503 than the second fabric layer 502. The denier differential produces wicking 505 from the second fabric layer 502 to the first fabric layer 503. The moisture, once transported to the first fabric layer 503, may be adsorbed to and spread over the increased surface area of the first fabric layer 503. The increased surface area of the first fabric layer 503 can encourage moisture evaporation 506 from the first fabric layer 503. The moisture management fabric can thus transport moisture efficiently from the wearer 500, to the second fabric layer 502 to keep the wearer comfortable, and to the first fabric layer 503 to promote evaporation from the fabric to keep the wearer dry.
Any combination of the examples illustrated in
In one example, the first fabric layer may be knitted or woven of a first yarn of a first denier per filament of less than or equal to about 1.04 denier per filament or a microfiber, such as about 0.50 to about 1.04 denier per filament. The second fabric layer may be knitted or woven of a second yarn of a second denier per filament of greater than or equal to about 1.04 denier per filament or a macrofiber, such as about 1.04 to about 3.50. The denier differential between the first yarn and the second yarn may be at least about 0.54. The third fabric layer may be knitted or woven of a third yarn of a third denier per filament. In one example, the third denier per filament is less than or equal to about 1.04 denier per filament or a microfiber, such as about 0.50 to about 1.04 denier per filament. In another example, the third denier per filament is greater than or equal to about 1.04 or a macrofiber, such as about 1.04 to about 3.50. The third denier per filament may be a value less than the second denier per filament but greater than the first denier per filament. In another example, the fourth fabric layer may be knitted or woven of a fourth yarn of a fourth denier per filament. The fourth denier per filament may be less than or equal to about 1.04 denier per filament or a microfiber, such as about 0.50 to about 1.04 denier per filament. Alternatively, the fourth denier per filament may be greater than or equal to about 1.04 or a macrofiber, such as about 1.04 to about 3.50. The fourth denier per filament may be a value less than the second denier per filament but greater than the first denier per filament.
