Abstract

Aspects herein relate to a textile knitted with an adaptive yarn that incorporates insulation features as well as variable air permeability features. The adaptive textile may exhibit a baseline level of insulation. The adaptive textile is configured to exhibit a first air permeability when unexposed to a physical stimulus such as water and a second air permeability when exposed to the physical stimulus where the second air permeability is greater than the first air permeability.

First claim

What is claimed is:

1. A garment comprising:
a first garment portion formed of a first knit material having an outer-facing surface and an inner-facing surface, the first knit material formed using at least:
a first yarn that is configured to be dimensionally stable upon exposure to moisture,
a second yarn that is configured to transition from a crimped state to an uncrimped state upon exposure to the moisture, to cause an increase in air permeability of the first knit material, the second yarn plated with the first yarn such that the first yarn generally forms the outer-facing surface of the first knit material and the second yarn is generally positioned under the first yarn, and
a third yarn forming the inner-facing surface of the first knit material, the third yarn forming terry loops that extend from the inner-facing surface of the first knit material, wherein the terry loops are clustered together in groups such that each group of terry loops forms a respective projection of a plurality of discrete projections, each projection of the plurality of discrete projections having a terminal end located opposite the outer-facing surface of the first knit material, each projection of the plurality of discrete projections forming a geometric shape with linear sides, each projection of the plurality of discrete projections separated from an adjacent projection by a space.

2. The garment of claim 1 , wherein the first yarn comprises 50% non-absorptive polyester fibers or filaments and 50% non-absorptive cationic dyeable polyester fibers or filaments.

3. The garment of claim 2 , wherein the second yarn is a bi-component yarn formed from Nylon 6 fibers or filaments and non-absorptive cationic dyeable polyester fibers or filaments.

4. The garment of claim 3 , wherein the second yarn comprises 50% Nylon 6 fibers or filaments and 50% non-absorptive cationic dyeable polyester fibers or filaments.

5. The garment of claim 1 , wherein the third yarn is configured to be dimensionally stable upon exposure to the moisture.

6. The garment of claim 5 , wherein the third yarn comprises 100% non-absorptive polyester fibers or filaments.

7. The garment of claim 1 , wherein the first garment portion is configured to exhibit a first air permeability when unexposed to the moisture, and wherein the first garment portion is configured to exhibit a second air permeability when exposed to the moisture, the first air permeability being less than the second air permeability.

8. The garment of claim 1 , the garment further comprising a second garment portion formed of a second knit material, the second yarn being absent from the second knit material.

9. A garment comprising:
a torso region having at least a front area, a back area, a first arm opening, a second arm opening, a first side area extending from proximate the first arm opening to proximate a waist opening of the garment, and a second side area extending from proximate the second arm opening to proximate the waist opening of the garment;
wherein a first portion of the garment is formed from a first knit material having an outer-facing surface and an inner-facing surface, the first knit material comprising at least:
a first yarn that is configured to be dimensionally stable upon exposure to moisture,
a second yarn that is configured to transition from a crimped state to an uncrimped state upon exposure to the moisture, to cause an increase in air permeability of the first knit material, the second yarn plated with the first yarn such that the first yarn generally forms the outer-facing surface of the first knit material and the second yarn is generally positioned under the first yarn, and
a third yarn that is configured to be dimensionally stable upon exposure to the moisture, the third yarn forming the inner-facing surface of the first knit material, the third yarn forming terry loops that extend from the inner-facing surface of the first knit material, wherein the terry loops are clustered together in groups such that each group of terry loops forms a respective projection of a plurality of discrete projections, each projection of the plurality of discrete projections having a terminal end located opposite the outer-facing surface of the first knit material, each projection of the plurality of discrete projections forming a geometric shape with linear sides, each projection of the plurality of discrete projections separated from an adjacent projection by a space.

10. The garment of claim 9 , wherein the first portion of the garment is positioned at least in a vertical direction along a central portion of the back area of the torso region.

11. The garment of claim 9 , wherein the first knit material is configured to exhibit a first air permeability when unexposed to the moisture, and wherein the first knit material is configured to exhibit a second air permeability when exposed to the moisture, the second air permeability being greater than the first air permeability.

12. The garment of claim 11 , wherein the second air permeability is at least 25% greater than the first air permeability.

13. The garment of claim 9 , the garment further comprising a second portion formed of a second knit material, the second yarn being absent from the second knit material.
