Patent ID: 7828029

Claim:
A method for making a puncture and abrasion resistant, air and water impervious laminated fabric, comprising: (a) providing a fabric in which high performance yarns are a major constituent thereof, the yarns being selected from the group consisting of extended chain polyethylene, ultra high molecular weight polyethylene, and aramids and having a denier between about 360 and 1,200; (b) positioning a first thermoplastic film directly on at least one side of the fabric, the thermoplastic film comprising ethylene vinyl acetate and having a thickness of between about 2 and 8 mils; (c) positioning a second, outer thermoplastic film over the first thermoplastic film on the at least one side of the fabric, the second thermoplastic film selected from the group consisting of high density polyethylene and low density polyethylene and having a thickness of between about 1.5 and 20 mils; (d) applying a pressure of between about 50 and 500 psi to the fabric and thermoplastic films at a temperature between about 200 degrees Fahrenheit and 285 degrees Fahrenheit; and (e) maintaining the pressure and temperature for between about 5 minutes and 15 minutes so that the first thermoplastic film bonds to the fabric and the second thermoplastic film softens and bonds to the first thermoplastic film.
