Dyeing Properties of Warm-Dyeing Reactive Dyes for Viscose/Chitin Blend Fiber

Abstract:

In this work, the dyeing properties of three warm-dyeing reactive dyes (C.I. Reactive Orange 16, Red 198 and Blue 222) for functional viscose/chitin blend fiber containing partially deacetylated chitin were investigated. Under all the dyeing conditions, reactive dyes exhibited higher exhaustion and fixation on viscose/chitin fiber than on conventional viscose fiber. The difference of dye exhaustion and fixation between viscose/chitin and viscose fibers became greater in the following cases: low to moderate dye concentration, low dyeing temperature, no alkali, the use of the dyes with low molecular weight, etc. The dependence of the exhaustion and fixation of reactive dyes on temperature on viscose/chitin fiber was less than that on viscose fiber. The reactive dyeing of viscose/chitin fiber required only a low dosage of sodium carbonate.
