Abstract

Aspects herein are directed to an article of apparel having a vent opening formed by overlapping the edges of a first panel and a second panel. A plurality of discrete overlay film structures are applied to the second panel adjacent to the vent opening. When the article of apparel is exposed to an external stimulus, the film structures undergo a reversible increase in dimension in at least the z-direction which cause the second panel of material to undergo a reversible decrease in dimension in the direction of a longitudinal axis of the vent opening thereby causing the vent opening to dynamically transition from a closed state to an open state.

First claim

What is claimed is:

1. An article of apparel comprising:
a first panel having a first panel edge;
a second panel having a second panel edge, wherein the first panel edge is discontinuously affixed to the second panel edge to form a vent opening having a longitudinal axis; and
a plurality of discrete overlay film structures affixed to the second panel, each of the plurality of discrete overlay film structures comprising a thermoplastic polyester elastomer configured to diffuse moisture from a first surface of the discrete overlay film structure to an opposite second surface of the discrete overlay film structure, each of the plurality of discrete overlay film structures having a long axis and a short axis, wherein the long axis of the each of the plurality of discrete overlay film structures is oriented substantially perpendicular to the longitudinal axis of the vent opening, and wherein upon exposure to moisture the plurality of discrete overlay film structures undergo an increase in dimension in at least a z-direction to cause the vent opening to transition from a closed state to an open state.

2. The article of apparel of claim 1 , wherein the plurality of discrete overlay film structures are not affixed to the first panel.

3. The article of apparel of claim 1 , wherein the plurality of discrete overlay film structures are affixed to an inner-facing surface of the second panel.

4. The article of apparel of claim 1 , wherein the plurality of discrete overlay film structures are affixed to an outer-facing surface of the second panel.

5. The article of apparel of claim 1 , wherein the each of the plurality of discrete overlay film structures has a thickness from about 30 microns to about 50 microns.

6. The article of apparel of claim 1 , wherein the longitudinal axis of the vent opening extends in a first direction.

7. The article of apparel of claim 6 , wherein when the plurality of discrete overlay film structures are exposed to moisture, the second panel undergoes a decrease in dimension in the first direction.

8. The article of apparel of claim 1 , wherein the plurality of discrete overlay film structures are affixed to the second panel at a location adjacent to the vent opening.

9. The article of apparel of claim 1 , wherein the article of apparel is an upper-body garment.

10. The article of apparel of claim 1 , wherein the article of apparel is a lower-body garment.

11. An article of apparel comprising:
a first panel having a first panel edge;
a second panel having a second panel edge, wherein the first panel edge is discontinuously affixed to the second panel edge to form a vent opening having a longitudinal axis extending in a first direction; and
a plurality of discrete overlay film structures affixed to the second panel, the plurality of discrete overlay film structures having a thickness from about 30 microns to about 50 microns, wherein upon exposure to moisture the plurality of discrete overlay film structures undergo a change in dimension in at least a z-direction to cause the second panel to undergo a decrease in dimension in the first direction thereby transitioning the vent opening from a closed state to an open state.

12. The article of apparel of claim 11 , wherein each of the plurality of discrete overlay film structures includes a long axis and a short axis.

13. The article of apparel of claim 12 , wherein the long axis of the each of the plurality of discrete overlay film structures is oriented substantially perpendicular to the longitudinal axis of the vent opening.

14. The article of apparel of claim 11 , wherein the plurality of discrete overlay film structures are not affixed to the first panel.

15. The article of apparel of claim 14 , wherein the first panel does not undergo a decrease in dimension in the first direction when the plurality of discrete overlay film structures are exposed to moisture.

16. The article of apparel of claim 11 , wherein the plurality of discrete overlay film structures comprise a thermoplastic polyester elastomer.

17. An article of apparel comprising:
a first panel having a first panel edge;
a second panel having a second panel edge, wherein the first panel edge is discontinuously affixed to the second panel edge to form a vent opening having a longitudinal axis extending in a first direction; and
a plurality of discrete overlay film structures affixed to the second panel, the plurality of discrete overlay film structures having a thickness less than or equal to 100 microns, wherein upon exposure to moisture the plurality of discrete overlay film structures undergo a change in dimension in at least a z-direction to cause the second panel to undergo a decrease in dimension in the first direction thereby transitioning the vent opening from a closed state to an open state.

18. The article of apparel of claim 17 , wherein each of the plurality of discrete overlay film structures comprises a thermoplastic polyester elastomer configured to diffuse moisture from a first surface of the discrete overlay film structure to an opposite second surface of the discrete overlay film structure.
