Vat Dyeing Properties of a Novel Regenerated Cellulosic Fiber

Abstract

The dyeing behavior of a novel regenerated cellulosic fiber (enVix®), prepared from secondary cellulose acetate fibers by the hydrolysis of acetyl groups, is investigated with three vat dyes. The effect of liquor ratio, temperature, and dye concentration on the dyeing properties of the enVix and viscose rayon are evaluated. The enVix exhibits better dyeability and fastness than viscose rayon, presumably due to its lower crystallinity.
