Abstract

An article of apparel is described which is effective to regulate the temperature of the wearer. In an embodiment, the article of apparel includes a base textile with a thermal regulation membrane. The thermal regulation membrane contains a plurality of system-reactive components selectively engaged heat and/or moisture. In an embodiment, the printed coating includes a cooling agent, a phase change material, and a heat dissipation material. In operation, the article of apparel is effective to delay/diminish the rise in skin temperature (compared to a garment lacking the membrane), increasing wearer comfort.

First claim

We claim:

1. An article of apparel comprising:
a textile substrate; and
a thermal regulation membrane on a surface of the textile substrate, the thermal regulation membrane comprising a plurality of system reactive components and a binder that adheres the system reactive components to the textile substrate, wherein the plurality of system reactive components comprises a water-activated cooling agent present in an amount from 15 wt % to 35 wt % of the system reactive components, wherein the water activated cooling agent comprises a polyol, a reversible-state, latent heat agent present in an amount from 25 wt % to 45 wt % of the system reactive components, wherein the latent heat agent comprises a paraffin linear chain hydrocarbon having 15-20 carbon atoms, and a mineral heat dissipation agent present in an amount from 25 wt % to 45 wt % of the system reactive components, wherein the heat dissipation agent comprises a silicate mineral, the silicate mineral comprising jade;
wherein the thermal regulation membrane is discontinuous and defines treated areas and untreated areas along the substrate surface.

2. An article of apparel comprising:
a textile substrate; and
a thermal regulation membrane on a surface of the textile substrate, the thermal regulation membrane comprising a plurality of system reactive components and a binder that adheres the system reactive components to the textile substrate, wherein the plurality of system reactive components comprises a water-activated cooling agent present in an amount from 15 wt % to 35 wt % of the system reactive components, wherein the water activated cooling agent comprises a polyol, a reversible-state, latent heat agent present in an amount from 25 wt % to 45 wt % of the system reactive components, wherein the latent heat agent comprises a paraffin, and a mineral heat dissipation agent present in an amount from 25 wt % to 45 wt % of the system reactive components, wherein the heat dissipation agent comprises a silicate mineral, wherein the silicate mineral comprises jade;
wherein the thermal regulation membrane is discontinuous and defines treated areas and untreated areas along the substrate surface.

3. The article of apparel of claim 2 , wherein the latent heat agent comprises a paraffin linear chain hydrocarbon having 15-20 carbon atoms.

4. The article of apparel of claim 2 , wherein:
the water-activated cooling agent comprises a crystalline polyol selected from the group consisting of sorbitol, xylitol and erythritol.

5. The article of apparel of claim 2 , wherein the binder comprises polyurethane.

6. The article of apparel of claim 2 , wherein the textile substrate is selected from the group consisting of a woven fabric, a knitted fabric, and a nonwoven fabric.

7. The article of apparel of claim 6 , wherein the textile substrate includes a first surface and a second surface opposite the first surface, and the thermal regulation membrane is on the first surface.

8. The article of apparel of claim 7 , wherein:
the first surface of the textile substrate is a wearer-facing surface of the article of apparel such that the thermal regulation membrane contacts the wearer when the article of apparel is worn by the wearer.

9. The article of apparel of claim 8 , wherein:
the first surface of the textile substrate defines a surface area; and
the thermal regulation membrane covers up to 30% of the surface area of the first surface of the textile substrate.

10. The article of apparel of claim 2 , wherein the untreated areas comprise a plurality of intersecting channels disposed between and separating sections of treated areas.

11. The article of apparel of claim 10 , wherein 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 surface of the textile substrate, each pattern unit comprising a central untreated area portion and a plurality of untreated area channels extending continuously and radially from the central untreated area portion to a location distant from the central untreated area portion.

12. The article of apparel of claim 2 , wherein the thermal regulation membrane contains pores that facilitate transport of water within the thermal regulation membrane.

13. The article of apparel of claim 2 , wherein the surface of the textile substrate comprises a bimodal surface in which water absorption, heat absorption and heat dissipation properties differ between the treated areas and the untreated areas of the surface of the textile substrate.
