Abstract

507,128. Viscose staple fibres. SCHLESISCHE ZELLWOLLE AKT.-GES. Aug. 15, 1938, No. 24066. Convention date, Aug. 23, 1937. [Class 2 (ii)] Viscose fibres are curled or loosened by treatment with hot dilute solutions of alkali metal carbonates either before, during, or after stapling. The treatment can be carried out before the spinning acid has been removed from the fibres, or when it has been partly removed. A further modification is first to remove completely the spinning acid, then reacidify with a volatile organic acid such as acetic acid, and finally treat with the hot carbonate solution.
