Studies on Dyeing of Wool Fabrics Treated with Chitosan by M Reactive Dyes

Yang Jing-xin

Abstract

In this paper, the dyeing behaviors of wool fabrics were treated with chitosan by following factors, deacetylation degree, concentration, pH value and temperature. The results showed that upgrading the concentration or deacetylation degree could increase fixing rate and K/S value. Chitosan also had no great effect on color fastness. Molecular weight of chitosan had no obvious effects on the dyeing behaviors.
