Abstract

A procedure for producing synthetic acrylic fibers characterized by extruding a spinning solution, which is prepared by dissolving in an inorganic solvent, acrylonitrile polymers, in air or an inert gas that is a non-coagulating gas for the spinning solution, leading it to an aqueous coagulation bath to form the fibers, wash said fibers with water, first stretch said fibers in a heating medium, then dry said fibers and re-stretch said fibers, later, in a steam heating medium.
