Abstract

A woven fabric coated in a single pass with a polymer blend to promote adhesion and impart abrasion resistance to the fabric simultaneously. An intimate blend of a binding thermoplastic and an abrasion resistant thermoplastic is extruded onto the woven fabric.

Claims

1. A solid fabric comprising a woven fabric coated with a polymer blend comprising a binding thermoplastic and an abrasion resistant thermoplastic.

2. The fabric of claim 1, wherein the woven fabric comprises at least one of polypropylene, polyethylene, or polyethylene terephthalate.

3. The fabric of claim 1, wherein the binding thermoplastic comprises approximately 15-30% methyl acrylate.

4. The fabric of claim 1, wherein the abrasion resistant thermoplastic comprises at least one of low density polyethylene, high density polyethylene, or linear low density polyethylene.

5. The fabric of claim 1, wherein the polymer blend comprises approximately 50-90% ethyl methyl acrylate.

6. The fabric of claim 1, wherein the polymer blend comprises approximately 10-50% low density polyethylene.

7. The fabric of claim 1, wherein the polymer blend comprises approximately 75% ethyl methyl acrylate and approximately 25% low density polyethylene.

8. The fabric of claim 1, wherein the polymer blend comprises approximately 85% ethyl methyl acrylate and approximately 15% low density polyethylene.

9. The fabric of claim 1, wherein the polymer blend is extruded on to the woven fabric.

10. The fabric of claim 9, wherein the woven fabric is Corona treated prior to extrusion.

11. The fabric of claim 9, wherein the woven fabric is heated prior to extrusion.

12. A method of forming a coated fabric comprising:

a. providing a woven fabric; and

b. extruding on a side of the woven fabric a polymer blend comprising a binding thermoplastic and an abrasion resistant thermoplastic.

13. The method of claim 12, wherein the woven fabric comprises at least one of polypropylene, polyethylene, or polyethylene terephthalate.

14. The method of claim 12, wherein the binding thermoplastic comprises approximately 15-30% methyl acrylate.

15. The method of claim 12, wherein the abrasion resistant thermoplastic comprises at least one of low density polyethylene, high density polyethylene, or linear low density polyethylene.

16. The method of claim 12, wherein the polymer blend comprises between approximately 50-90% ethyl methyl acrylate.

17. The method of claim 12, wherein the polymer blend comprises between approximately 10-50% low density polyethylene.

18. The method of claim 12, further comprising Corona treating the side of the woven polypropylene fabric prior to extrusion.

19. The method of claim 12, further comprising heating at least the side of the woven polypropylene fabric prior to extrusion.

20. A solid fabric comprising a woven polypropylene fabric coated with a polymer blend comprising a binding thermoplastic and an abrasion resistant thermoplastic, wherein the binding thermoplastic comprises ethyl methyl acrylate and the abrasion resistant thermoplastic comprises low density polyethylene.
