ABSTRACT:
Polyvinyl chloride fibers obtainable by molding a resin composition containing 100 parts by weight of a vinyl chloride resin, from 3 to 20 parts by weight of a compatible chlorinated vinyl chloride resin, from 10 to 30 parts by weight of a heat resistant chlorinated vinyl chloride resin, and from 0.1 to 10 parts by weight of a heat stabilizer into a fibrous form, the compatible chlorinated vinyl chloride resin having a chlorine content of from 57 to 64% by weight and an average degree of polymerization of from 450 to 800; and the heat resistant chlorinated vinyl chloride resin having a chlorine content of from 65 to 71% by weight and an average degree of polymerization of from 450 to 1,100, to a process of producing the same and to applications thereof.
