Abstract

Aspects herein are directed to an apparel item that promotes thermo-regulation through the use of engineered openings, venting, and/or stand-off structures. In exemplary aspects, 20-45% of the apparel item may comprise the engineered openings. Vents may be positioned on the apparel item in areas that experience high amounts of air flow to help channel air into the apparel item. The stand-off structures may be positioned on an inner-facing surface of the apparel item where they help to create a space between the apparel item and the wearer's body surface in which air can flow and help cool the wearer by promoting evaporative cooling.

First claim

What is claimed is:

1. A method of forming an apparel item having stand-off structures, the method comprising:
providing a textile material comprising a first surface, and a second surface opposite the first surface;
applying tension in an x-direction and in a y-direction to the textile material;
applying a surface treatment to the first surface of a plurality of first portions of the textile material while maintaining the plurality of first portions of the textile material under tension, wherein the surface treatment is not applied to a plurality of second portions of the textile material, the plurality of second portions positioned adjacent to the plurality of first portions;
incising the plurality of first portions of the textile material while maintaining the plurality of first portions under tension to form one or more openings; and
releasing the tension from the textile material, wherein upon releasing the tension from the textile material, the plurality of first portions with the one or more openings form a plurality of vent structures that extend outward in a z-direction with respect to the textile material, and wherein the one or more vent structures are configured to facilitate air flow from the first surface to the second surface of the textile material.

2. The method of claim 1 , wherein the textile material comprises a pattern piece for the apparel item.

3. The method of claim 1 , wherein the tension is applied such that the textile material is stretched to 110 to 160% of its resting length.

4. The method of claim 1 , further comprising curing the surface treatment while the textile material is under tension.

5. The method of claim 4 , further comprising releasing the tension applied to the textile material after the surface treatment has been applied.

6. The method of claim 5 , further comprising applying steam to the textile material after the tension is released.

7. The method of claim 6 , further comprising forming the textile material into an upper torso garment.

8. The method of claim 7 , wherein when the textile material is formed into the upper torso garment, the first surface of the textile material comprises
an inner-facing surface of the upper torso garment.
