Abstract

An article of apparel includes a first layer and a second layer. The first layer includes a four way stretch material. The second layer, coupled to the first layer, includes an auxetic layer.

First claim

What is claimed is:

1. An article of apparel comprising:
a first fabric layer comprising resilient fabric;
a second fabric layer comprising a resilient fabric; and
an auxetic layer positioned between the first fabric layer and the second fabric layer, the auxetic layer comprising an auxetic structure defining a pattern of voids, wherein the first layer is exposed within at least one void of the auxetic layer.

2. The article of apparel of claim 1 wherein at least one void of the pattern of voids defines a reentrant shape.

3. The article of apparel of claim 1 wherein at least one void of the pattern of voids in the auxetic structure is at least partially filled with a foam.

4. The article of apparel of claim 1 wherein at least one void of the pattern of voids in the auxetic structure is at least partially filled with a hot melt material.

5. The article of apparel of claim 1 wherein the first fabric layer is a four way stretch material.

6. The article of apparel of claim 1 wherein the auxetic structure is comprised of a polymer material.

7. The article of apparel of claim 6 , wherein the polymer material is foam.

8. The article of apparel of claim 1 , wherein the auxetic structure defines a repeating pattern of voids.

9. An article of apparel comprising:
a first layer comprising resilient fabric;
a second layer comprising resilient fabric; and
an intermediate layer positioned between and coupled to each of the first layer and the second layer, the intermediate layer comprising an array of cells, each cell within the array of cells comprising interconnected members surrounding a void, the first layer being exposed within the area of the void,
wherein the intermediate layer possesses a Poisson's ratio of less than 0.15.

10. The article of apparel according to claim 9 , wherein a cell within the array of cells possesses an interior angle greater than 180°.

11. The article of apparel according to claim 9 , wherein the intermediate layer possesses a Poisson's ratio of less than 0.

12. The article of apparel according to claim 9 , wherein the cell voids are substantially uniform in size and shape.

13. The article of apparel according to claim 9 , wherein the resilient fabric forming the first layer comprises a four-way stretch fabric.

14. The article of apparel according to claim 9 , wherein each of the resilient fabric forming each of the first layer and the second layer comprises a four-way stretch fabric.

15. The article of apparel according to claim 9 , wherein the segments of the intermediate layer are formed of resilient polymer.

16. The article of apparel according to claim 9 , wherein the intermediate layer is bonded directly to the first layer.

17. That article of apparel according to claim 9 , wherein the array of cells comprises a repeating pattern of cells.

18. The article of apparel according to claim 9 , wherein the intermediate layer couples the first layer to the second layer.
