Abstract

An article of apparel is formed that is effective to regulate the temperature of the wearer. In an embodiment, a thermal regulation composition is obtained comprising a binder, a cooling agent, a latent heat agent, and a heat dissipation agent. The thermal regulation composition is printed to a surface of a textile by pressing the thermal regulation composition against the textile surface such that the binder adheres the cooling agent, latent heat agent, and the heat dissipation agent to the surface of the textile, thereby forming a thermal regulation membrane, and the textile is incorporated into an article of apparel.

First claim

We claim:

1. A method of forming an article of apparel, the method comprising:
obtaining a thermal regulation composition comprising a plurality of system reactive components, wherein the system reactive components comprise a binder, a water-activated cooling agent, a reversible state latent heat agent, and a mineral heat dissipation agent, the water-activated cooling agent is present in an amount from 15 wt % to 35 wt % of the system reactive components, the reversible state latent heat agent is present in an amount from 25 wt % to 45 wt % of the system reactive components, and the mineral heat dissipation agent is present in an amount from 25 wt % to 45 wt % of the system reactive components;
printing the thermal regulation composition to a surface of a textile by pressing the thermal regulation composition against the textile surface such that the binder adheres the water-activated cooling agent, the reversible state latent heat agent, and the mineral heat dissipation agent to the surface of the textile, thereby forming a thermal regulation membrane; and
incorporating the textile into an article of apparel.

2. The method of claim 1 , wherein the printing further comprises:
pressing the thermal regulation composition into the textile such that a first portion of the thermal regulation membrane is below the surface of the textile substrate while a second portion of the thermal regulation membrane remains above the textile substrate.

3. The method of claim 1 , wherein the water-activated cooling agent comprises a polyol.

4. The method of claim 1 , wherein the reversible state latent heat agent comprises a paraffin linear chain hydrocarbon having 15-20 carbon atoms.

5. The method of claim 1 , wherein the mineral heat dissipation agent comprises a silicate mineral.

6. The method of claim 1 , wherein the binder comprises a polyurethane.

7. 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.

8. The method of claim 1 , wherein the textile is incorporated into the article of apparel such the thermal regulation membrane faces a wearer of the article of apparel.

9. The method of claim 1 , wherein the thermal regulation membrane covers up to 30% of the surface area of the surface of the textile.

10. The method of claim 1 , wherein:
printing comprises pressing the thermal regulation composition in a discontinuous pattern along the surface of the textile, the discontinuous pattern forming a bimodal textile 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.

11. The method of claim 1 , further comprising compressing the textile by passing the textile between a pair of rollers heated to a predetermined temperature, the roller pair applying a predetermined pressure to the textile.

12. The method of claim 11 , wherein compressing the textile with the thermal regulation membrane occurs at a temperature ranging from 25° C. to 55° C. and at a pressure ranging from 30 lbs to 70 lbs.

13. An article of apparel comprising:
a textile substrate including a first surface and a second surface opposite the first surface; and
a thermal regulation membrane formed as a printed coating by pressing a thermal regulation material on the first surface of the textile substrate such that a first portion of the formed thermal regulation membrane is below the first surface of the textile substrate while a second portion of the thermal regulation membrane is exposed above the first surface of the textile substrate, the thermal regulation membrane comprising a plurality of system reactive components, the system reactive components being selectively engaged in response to conditions of a wearer wearing the article of apparel, wherein the plurality of system reactive components comprises a cooling agent present in an amount from 15 wt % to 35 wt % of the system reactive components and comprising a polyol, a latent heat agent present in an amount from 25 wt % to 45 wt % of the system reactive components and comprising a paraffin linear chain hydrocarbon having 15-20 carbon atoms, and a heat dissipation agent present in an amount from 25 wt % to 45 wt % of the system reactive components and comprising a silicate mineral.

14. The article of apparel of claim 13 , wherein the silicate mineral comprises jade.

15. The article of apparel of claim 13 , wherein the thermal regulation membrane is discontinuous and defines treated areas and untreated areas along the first substrate surface, and the untreated areas comprise a plurality of intersecting channels disposed between and separating sections of treated areas.
