Effect of cationisation on reactive printing of leather and wool

Abstract

The resurgent interest in leather and wool clothing has led to developments in brilliant colours with different shades on leather and wool that hold promise for re-opening this market for the two substrates. It is necessary to use more than one class of dyestuff under variety of conditions in this work and to modify the two components before printing. Fibre reactive dyes with three different reactive groups, mono-chloro triazine (Cibacron Yellow P6GS), dichloro-triazine (Procion Red MX-5B) and vinyl sulphone (Remazol Brilliant Orange FR), were used to print both unmodified and modified, i.e. cationised leather and wool substrates using Tenofix Extra ECO and Solfix E cationic reagents. Pre-cationisation of leather and wool brings about an improvement in the depth of the prints as well as in washing and light fastness properties
