Dyeing Of Cellulose Textile Material With Reactive Dyes

摘要

It is investigated the dyeing of the reactive Intracron G. Yellow CDX-ED, Intracron Red CDX-ED and Intracron Blue CDX-ED dyes by methods: isothermal, where salt is added in the beginning of the process; with controlled heating, where an alkaline agent is added at the beginning and isothermal, where salt and alkaline agent are added gradually. It is established that with both types of alkaline agent and for all three dyes, the most intensive coloring is achieved when method II is used. The color is, however, more intense with the first type of agent (salt + Na_2CO_3) than with the second one (salt + Na_2CO_3 + NaOH). On the base of comparing the kinetics curves of exhaustion is established that the investigated reactive dyes are not suited to be used in trichromy.
