Abstract

Anti-static polymeric films, fibers and textile yarn produced by process comprising admixing a branched chain, sulfur-containing polyester with a synthetic film- or fiber-forming polymer, extruding said film or textile fiber, and exposing said film or textile fiber to an aqueous solution containing a polyvalent metal ion reactive with the sulfate groups present in said sulfur-containing polyester. The sulfur-containing polyester is thereby fixed within the synthetic film or fiber and is resistant to extraction by water or commonly used dry cleaning solvents.
