Abstract

Procedure for obtaining non-flammable fibers with good physical qualities, which at the same time have a degree of chlorine between 25 and 40%, a bond point greater than 215ºC and a percentage of dimensional contraction less than 32% by treatment at 130ºC without tension in the presence of water vapor; characterized in that it is dissolved in a polar organic solvent, a mixture of: 50-99% by weight of a copolymer containing 79.5 to 58% by weight of acrylonitrile, 20 to 40% by weight of vinylidene chloride and 0, 5 to 2% by weight of comonomer giving the dye affinity; 1 to 50% by weight of a copolymer containing 20 to 50% by weight of acrylonitrile and 50 to 80% by weight of vinylidene chloride; presenting this mixture a demixing between 1 and 3μ; this solution is extruded through a die in a coagulating bath containing 30 to 60% by weight of water and 70 to 40% of spinning solvent, at a temperature of between 0 and 20ºC; the extracted threads are washed; they are stretched to a degree of 2 to 4X, at a temperature between 90 and 130ºC; and finally they dry.
