Abstract
A method for making a cut and puncture resistant laminated fabric under a laminating pressure including the steps of rolling a thermoplastic film and a fabric constructed with a substantial majority of a high performance fiber around a small diameter core to form a wound bundle. The wound bundle is heated at a temperature of between about 250 and about 285 degrees Fahrenheit for a sufficient length of time to laminate the thermoplastic film to the fabric.
Claims28
A method for making a cut and puncture resistant laminated fabric under a laminating pressure comprising:
- a) rolling a thermoplastic film having at least about 20% ethylene content and a fabric comprised of a high performance fiber together under tension to form a wound bundle;
- and
- b) heating the wound bundle at a sufficient temperature and for a sufficient length of time so as to soften the thermoplastic film such that shrinkage of the high performance fabric generates the laminating pressure to laminate said thermoplastic film to said high performance fabric.
