STUDIES ON ACRYLIC SYNTHETIC FIBERS

(XXIV) ON THE CHEMICAL PROPERTIES

Abstract

The chemical properties of pure P. A. N fibers and Co-polymer fibers were studied with the following results;
1) HNO₃ has bleaching action
2) AAm Co-polymer fibers treated with HCl (>20%) can be dyed with acid colors
3) AA (CH₂ CH-COOH) Copolymer treated with Amine compounds shows good dyeability to Acid dryes
