Patent AT-E3997-T1: [Translated] ACRYLIC FIBERS WITH IMPROVED DYEABILITY FOR BASIC DYES AND PROCESS FOR THE MANUFACTURE OF SAME.
Description
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 throughout the spinning dope and the fibers formed from the dope. Fibers formed from this polystyrene-containing dope have improved basic dyeability.
