ABSTRACT:
Novel antiflaming fibers having excellent dyeability and heat resistance are prepared from a matrix-polymerized resin which comprises polymerizing acrylonitrile in the matrix of a vinyl chloride resin. A vinyl chloride resin and/or an acrylonitrile resin can be added in a specific amount to the matrix-polymerized resin when dissolved in a spinning solvent. Substantially the same fibers are also prepared from blended polymers which comprise blending a specific vinyl chloride resin and a specific acrylonitrile resin in the specific proportion, by employing the coagulation bath of an aqueous solution of calcium chloride.
