Abstract

An article of apparel includes a first layer and a second layer. An auxetic structure penetrates the first layer. The auxetic structure includes a plurality of interconnected members forming an array of cell units. Each of the plurality of interconnected members form cell walls with interior recesses defined within the cell walls. The second layer is coupled to the first layer via the auxetic structure.

First claim

What is claimed is:

1. An article of apparel comprising:
a first layer;
a second layer; and
a bonding layer positioned between the first layer and the second layer, the bonding layer forming an auxetic structure defining a repeating pattern of perimeter walls and interior recesses.

2. The article of apparel of claim 1 wherein the first layer is an interior layer and the second layer is an exterior layer.

3. The article of apparel of claim 2 wherein at least one of the interior layer and the exterior layer is a textile layer.

4. The article of apparel of claim 3 wherein the textile layer is provided by a four way stretch material.

5. The article of apparel of claim 3 wherein the bonding layer is provided by an adhesive material.

6. The article of apparel of claim 5 wherein the adhesive material is at least partially embedded in the textile layer.

7. The article of apparel of claim 1 wherein the article of apparel is an article of footwear.

8. The article of apparel of claim 1 wherein the perimeter walls of the auxetic structure comprise a plurality of interconnected wall segments that form a repeating pattern of reentrant polygonal shapes.

9. The article of apparel of claim 1 wherein the auxetic structure has a Poisson's ratio of substantially zero or less than zero.

10. The article of apparel of claim 1 wherein the bonding layer is a printed layer.

11. The article of apparel of claim 1 wherein the exterior layer is provided by a sheer material and the bonding layer is visible through the sheer material.

12. An article of apparel comprising:
a first layer defining a first surface;
an auxetic structure penetrating the first surface of the first layer, the auxetic structure including a plurality of interconnected members forming an array of cell units, each of the plurality of interconnected members forming cell walls with interior recesses defined within the cell walls, the cell walls forming a repeating pattern of reentrant polygonal shapes; and
a second layer coupled to the first layer via the auxetic structure.

13. The article of apparel of claim 12 wherein the auxetic structure further penetrates the second layer.

14. The article of apparel of claim 12 wherein the auxetic structure is an adhesive material printed on the first layer.

15. The article of apparel of claim 12 wherein the first layer is a four-way stretch material and the second layer is a leather material or a synthetic leather material.

16. The article of apparel of claim 12 wherein the article of apparel is an article of footwear.

17. An article of apparel including a textile laminate comprising:
an interior layer possessing an interior layer Poisson's value;
an exterior layer possessing an exterior layer Poisson's value; and
a bonding layer positioned between the interior layer and the exterior layer, the bonding layer forming an auxetic structure defining a repeating pattern of perimeter walls and interior recesses, wherein the bonding layer is at least partially embedded in the interior layer and the exterior layer, and wherein the textile laminate possesses a laminate Poisson's value that is less than at least one of the interior layer Poisson's value and the exterior layer Poisson's value.

18. The article of apparel of claim 17 wherein at least one of the interior layer and the exterior layer is a textile layer, and wherein each of the interior layer Poisson's value and the exterior layer Poisson's value is a positive value.

19. The article of apparel of claim 18 wherein the interior layer is a resilient textile provided by a four way stretch material possessing stretch and recovery properties.

20. The article of apparel of claim 17 wherein the perimeter walls of the auxetic structure comprise a plurality of interconnected wall segments that form a repeating pattern of reentrant polygonal shapes.
