Abstract
One of the recurring problems observed with most of commercial anionic reactive dyes for dyeing nylon was the low degree of exhaustion and fixation. In this paper, a number of attempts were made to improve the fixation efficiency of an anionic reactive dye, Procion Rubine XL+, on modified nylon. This dye was selected for further study since, from the previous study, under non-optimised conditions fixation efficiency was particularly poor and therefore offered more scope for significant and readily observable improvements. The following process variables were studied;(a)effect of added alkali; dye was exhausted at pH 4 and then alkali added,(b) effect of added electrolyte, The addition of alkali and electrolyte during dyeing resulted in reduced dye fixation.
