ABSTRACT:
Non-inflammable filaments having good physical characteristics are disclosed, wherein the filaments have a chlorine content of 25-40% by weight and a sticking temperature of at least 215.degree.C, and a shrinkage of less than 32% when subjected to steam at 130.degree.C in the free or unrestrained state. The filaments are formed by spinning a mixture of incompatible polymers, one polymer, used in an amount of 50-99% by weight, containing 79.5 to 58 weight percent of acrylonitrile units, 20-40 weight percent of vinylidene chloride units and 0.5 to 2 weight percent of a comonomer which enhances dyeability, and the other copolymer, used in an amount of from 1-50 weight percent, containing from 20-50 percent by weight of acrylonitrile units and 50-80 percent of vinylidene chloride units.
The filaments may be used in textile applications, such as for clothing, furniture upholstery, and the like.
