Dyeing of cellulose textile material with reactive dyes

摘要

Polyfunctional reactive dyes have distinct advantages over monofunctional counterparts. The present paper envisages dyeing of cellulosics with polyfunctional reactive dyes. Dyeing was carried out by using three methods viz Isothermal salt at start, Isothermal salt added gradually and controlled heating. Dyeing process was compared based on their kinetics and depth of colour.
