C-14-53-0279 ACRYLIC FIBER HAVING IMPROVED BASIC DYEABILITY ABSTRACT OF THE DISCLOSURE Disclosed is an acrylic fiber having improved basic dyeability. The fiber is made by a process wherein a copolymer of an acrylic monomer and a sulfonated vinyl monomer is dissolved in a solvent to form a spinning dope and a solution of polystyrene in the same solvent is added to the dope prior to spinning the dope to form fibers. The polystyrene will be in the form of a separate phase dispersed through the spinning dope and the fibers formed from the dope. Fibers formed from this polystyrene- containing dope have improved basic dyeability.
