Abstract
Process for treating a synthetic acrylonitrile fiber, characterized in that it comprises preparing a solution of an acrylonitrile polymer comprising at least 80 weight percent acrylonitrile together with dissociable acid groups within the polymer in an aqueous solution of thiocyanic acid salt , extrude the solution into a fiber, treat the fiber with an aqueous solution of the inorganic alkali metal salt or ammonium salt at pH 2.2 to pH 4.0 so that it is combined from 75 to 95 percent of said acid groups dissociable with the alkali metal or ammonium ions and, finally, washing the fiber thus treated with water.
