Abstract

A multilayer material includes a first layer of polyether foam or polyurethane foam, a second layer of a woven or knitted material adherent to a first surface of the first layer, and a third layer of a reprocessed foam material, consisting of flakes of polyether, polyurethane or both within a polyether linking agents or a polyurethane linking agent, adherent to the second surface of the first layer.

Claims

1. A multilayer material including a first layer having a first and a second surfaces of a foam material chosen from a group consisting of polyether and polyurethane;

a second layer of a fabric material adherent to said first surface of said first layer; and

a third layer of a reprocessed foam material, comprising flakes of a material chosen from a group consisting of polyether and polyurethane within a linking agent chosen from a group consisting of polyether and polyurethane, adherent to said second surface of said first layer.

2. A multilayer material as claimed in claim 1 in which said first layer is within the range of 1/32 inch to 1/4 inch in thickness and said third layer is within the range of 1/32 inch to 1/4 inch in thickness.

3. A multilayer material as claimed in claim 2 in which said first layer is approximately 1/16 inch in thickness and said third layer is 1/4 inch in thickness.

4. A multilayer material as claimed in claim 1 in which said reprocessed foam has a density within the range of 8 to 11 pounds per cubic foot.

5. A multilayer material as claimed in claim 4 in which said reprocessed foam has a density of approximately 5 pounds per cubic foot.

6. A multilayer material as claimed in claim 1 in which said fabric material is a woven material.

7. A multilayer material as claimed in claim 1 in which said fabric material is a knitted material.

8. A multilayer material as claimed in claim 1 in which said fabric material is cotton drill.

9. A multilayer material as claimed in claim 4 in which said cotton drill has a count of approximately 60 ×

48 threads per square inch and a weight within the range of 2.2 to 2.25 pounds per cubic foot.

10. A multilayer material including a first layer having a first and a second surfaces of a foam material chosen from a group consisting of polyether and polyurethane, said first layer being between 1/32 and 1/4 inch in thickness;

a second layer of an absorbent fabric material adherent to said first surface of said first layer; and

a third layer of a reprocessed foam material having a density within the range of 8 to 11 pounds per cubic foot, said third layer comprising flakes of a material chosen from a group consisting of polyether and polyurethane within a linking agent chosen from a group consisting of polyether and polyurethane, adherent to said second surface of said first layer, and said third layer being between 1/32 and 1/4 inch in thickness.
