Abstract

An article of apparel is formed that is effective to regulate the temperature of the wearer. In an embodiment, a textile substrate is obtained, and a thermal regulation composition is applied to a surface of the textile substrate at a first temperature and a first pressure to form a coated textile substrate. The coated textile substrate is dried to form a thermal regulation membrane disposed on the surface of the textile substrate, and the textile substrate with the thermal regulation membrane is compressed at a second pressure and a second temperature to position a portion of the thermal regulation membrane below the surface of the textile substrate. The textile substrate is incorporated into an article of apparel. The thermal regulation composition can include one or more system reactive components provided within a binder, where a system reactive components can include a cooling agent, a latent heat agent and/or a heat dissipation agent.

First claim

We claim:

1 . A method of forming an article of apparel, the method comprising:
obtaining a textile substrate; applying a thermal regulation composition to a surface of the textile substrate at a first temperature and a first pressure to form a coated textile substrate; drying the coated textile substrate to form a thermal regulation membrane disposed on the surface of the textile substrate; and compressing the textile substrate with the thermal regulation membrane at a second pressure and a second temperature to position a portion of the thermal regulation membrane below the surface of the textile substrate; and incorporating the textile substrate into an article of apparel.

2 . The method of claim 1 , wherein applying comprises applying via a rotogravure apparatus.

3 . The method of claim 1 , wherein:
the first pressure differs from the second pressure; and the first temperature differs from the second temperature.

4 . The method of claim 1 , wherein:
the second temperature is from 25° C. to 55° C.; and the second pressure is from about 30 to 70 lbs.

5 . The method of claim 4 , wherein:
the second temperature is about 30° C.; and the second pressure is about 50 lbs.

6 . The method of claim 4 , wherein the compressing the textile substrate with the thermal regulation membrane at the second pressure and the second temperature comprises pressing the textile substrate with the thermal regulation membrane between heated rollers of a calendaring apparatus.

7 . The method of claim 6 , wherein the pressing comprises passing the textile substrate with the thermal regulation membrane between the heated rollers of the calendaring apparatus at a speed of 300 rpm to 400 rpm.

8 . The method of claim 1 , wherein:
applying comprises applying the thermal regulation composition in a discontinuous pattern including a plurality of linear elements to form a bimodal substrate surface defining treated and untreated areas; and properties of the untreated areas and the properties of the treated areas cooperate to provide the article of apparel with temperature regulation properties.

9 . The method of claim 8 , wherein the applying further comprises applying the thermal regulation composition in a discontinuous pattern such that the untreated areas comprise a plurality of intersecting channels disposed between and separating sections of treated areas.

10 . The method of claim 8 , wherein the applying further comprises applying the thermal regulation composition in a discontinuous pattern such that the intersecting channels of untreated areas and separated sections of treated areas of the thermal regulation membrane define a repeating pattern of pattern units along the substrate surface, each pattern unit comprising a central untreated area portion and a plurality of untreated area channels extending radially from the central untreated area portion to a location distant from the central untreated area portion.

11 . The method of claim 1 , wherein the thermal regulation composition comprises one or more system reactive components provided within a binder, and the one or more system reactive components are selected from the group consisting of a cooling agent, a latent heat agent, and a heat dissipation agent.

12 . The method of claim 11 , wherein the cooling agent comprises a polyol selected from the group consisting of sorbitol, xylitol and erythritol, and the latent heat agent comprises a phase change material comprising a paraffinic hydrocarbon.

13 . The method of claim 11 , wherein the heat dissipation agent comprises a silicate mineral.

14 . The method of claim 13 , wherein the silicate material is jade.

15 . The method of claim 11 , wherein the binder comprises polyurethane.

16 . The method of claim 1 , wherein the textile substrate is selected from the group consisting of a woven fabric, a knitted fabric, and a nonwoven fabric.

17 . The method of claim 1 , wherein the thermal regulation composition is applied to a surface of the textile substrate that defines a portion of a wearer-facing surface of the article of apparel such that the formed thermal regulation membrane faces a wearer of the article of apparel.

18 . The method of claim 17 , wherein the textile substrate is incorporated into an article of apparel such that the thermal regulation membrane covers up to 30% of a surface area defined by the surface of the textile substrate to which the thermal regulation composition is applied.

19 . The method of claim 1 , wherein the incorporating the textile substrate into the article of apparel comprises incorporating the textile substrate into a compression garment, an article of footwear, a jacket, a hat, a glove or an undergarment.
