Abstract

Various aspects disclosed relate to structure such as a textile, a garment, a garment component, footwear, or a footwear component. The present disclosure includes the structure having a first region having one of more first fibers. An individual first fiber includes co-extruded first and second filaments, the first filament formed of a first thermoplastic polymeric material. Due to expansion or contraction of the one or more first fibers, the first region contracts or expands on a change in relative humidity, relative to an equilibrium state of the first region prior to the change in relative humidity.

First claim

The invention claimed is:

1 . A textile comprising:
a first layer; a second layer adjacent the first layer; one or more first fibers attached to the first layer and the second layer; and an elastic component attached to the first layer and the second layer, the elastic component and the one or more first fibers being positioned adjacent each other; wherein:
the elastic component exerts an expanding force upon the first layer and the second layer that biases the second layer away from the first layer;
the one or more first fibers, in a first equilibrium state where the first layer is a first distance away from the second layer, exert a first contracting force upon the first layer and the second layer in opposition to the expanding force;
upon exposure to a moisture stimulus, the one or more first fibers contract to exert a second contracting force upon the first layer and the second layer that is greater than the expanding force so that the first layer and the second layer move towards each other; and
upon removal of the moisture stimulus, the one or more first fibers revert back to the first equilibrium state.

2 . The textile of claim 1 , wherein the second layer comprises an insulation material.

3 . The textile of claim 1 , wherein the second layer comprises an outer surface opposite the first layer.

4 . The textile of claim 3 , wherein the one or more first fibers is attached to the outer surface.

5 . The textile of claim 1 , wherein the one or more first fibers comprises co-extruded first and second filaments.

6 . The textile of claim 5 , wherein the co-extruded first and second filaments have an interface along the majority of the length of each of the individual first fibers.

7 . The textile of claim 6 , wherein the first and second filaments are substantially laminated to each other at the interface along the majority of the length of each of the individual first fibers.

8 . The textile of claim 1 , wherein the elastic component comprises polyurethane.

9 . The textile of claim 8 , wherein the elastic component comprises thermoplastic polyurethane.
