Abstract
Process for the production of synthetic fibers from polyacrylonitrile, characterized in that it comprises the extrusion of an aqueous solution of an acrylonitrile polymerization product containing a high proportion, by weight, of combined acrylonitrile, through a shaped orifice, to a liquid coagulating bath comprising an aqueous solution containing about 3 to 25% by weight of a water-soluble thiocyanate which produces highly hydrated ions in an aqueous solution, said coagulating bath being at a temperature comprised between 0 and 410º C and dissolving the cited acrylonitrile polymerization product in a concentrated aqueous solution of the same water-soluble thiocyanate, which is a component of said liquid coagulant bath.
