ABSTRACT:
An improved fabric is provided for use in a protective garment. The fabric has two composites seamed together. Each composite is formed from a spunbonded olefin which has been laminated to a three-layered thermoplastic film. Compared to a fabric with only one composite layer, various chemicals require more than 2.9 to more than 240 times as much time to penetrate the two-composite fabric of the invention.
