| titleOfInvention | Method of treating acrylonitrile synthetic fiber |
| abstract | A method of treating acrylonitrile synthetic fibers which involves preparing a solution of acrylonitrile polymer containing -SO3M or -OSO3M and at least 80 percent by weight of acrylonitrile in said polymer which is dissolved in an aqueous solution of the salt of thiocyanic acid, wet spinning said solution in water of a dilute aqueous thiocyanate solution, treating said fiber with an aqueous solution of the inorganic salt of alkali metal atoms or an ammonium salt at a pH of 2.2 to 4.0 to combine from 75 to 95 percent of said groups in the fiber with the alkali metal atoms or ammonium ions, and finally washing said fiber with water. |
