  • Patent number: 5071699
    Abstract: The present invention provides for an anti-static flexible fabric material formed from woven, axially oriented crystalline polypropylene yarn, said fabric further characterized as having a coating of a flexible, thermoplastic polymer on one or both sides of the fabric. Anti-static properties are imparted to the fabric by formulating the thermoplastic coating to contain from about 0.2 to about 8% by weight of a polyol ester (preferably glycerol) of a C.sub.10 to C.sub.28 fatty acid. The polypropylene yarn may optionally itself also contain a lesser amount of the polyol ester of a C.sub.10 to C.sub.28 fatty acid to provide a fabric having even more enhanced anti-static properties. In another embodiment, the polypropylene yarn may additionally have interwoven therewith or in contact therewith at intervals conductive yarns to provide even more enhanced anti-static properties.
