Abstract
In previous studies1, 2) it was pointed out that vinylon acetalized with a 20_??_30% solution of sulfuric acid as a catalyst had good dyeing properties with cationic dyes.This paper concerns with the improvement of the dyeing properties and the wash fastness of the fiber. In order to improve the dyeability and the wash fastness, an acid group was first introduced to poly (vinyl alcohol) (PVA) by acetalization with o-sulfobenzaldehyde and then a hydrophobic group was introduced by acetalization with formaldehyde. The fiber thus prepared showed the deep dyeing properties and the good fastness to light and washing.
