Feasibility of a one‐step process for desizing, scouring, bleaching and mercerising of cotton fabrics: dyeing kinetics of direct dyes in a finite bath

The purpose of this study is to explore the effect of dyeing kinetics of direct dyes on cotton fabrics which have been pretreated by the one‐step method. The results indicate that as the dip temperature or curing time is decreased, the equilibrium absorption and rate constant increase, while the activation energy decreased, Furthermore, all the measures of dyeing indicated poorer results with the one‐step method than the conventional method, although there was no significant difference observed in terms of the structural diffusion resistance constant.
