Why So Called Reactive Dye.
« on: May 22, 2018, 01:26:26 PM »
Reactive dyes are so called because this is the only type of dye, which has reactive group, and that reactive group reacts chemically with fibre polymer molecules and form covalent bond. This covalent bond is formed between the reactive group and terminal –OH (Hydroxyl) group of polyamide and wool fibre or between reactive group and terminal -NH2 (Amino) group of cellulosic fibre polymer. The strength of this covalent bond is more than ionic bond, hydrogen bond and Vander Waal’s force of attraction. Thus the reactive group becomes an integral part of the fibre.
For this reasons the dyes are so called. They are also called ‘fibre reactive group’.
