摘要
Modacrylic fibers having high retraction, reduced inflammability and high glossiness, prepared by wet spinning a solution, in an organic spinning solvent miscible with water, of a mixture of copolymers from acrylonitrile, vinylidene chloride, at least a vinyl ester and at least an unsaturated monomer containing at least a sulphonic group, the acrylonitrile units being from 50% to 85% by weight and the vinyl ester units from 3% to 6% by weight hot drawing the coagulated fiber in a mixture of water and spinning solvent drying the fiber in hot air while leaving it free concurrently to contract and subsequently further hot drawing it in air.
