Seam penetration in the dyeing of garments using reactive dyes. Part 2: Evaluation of the effect of processing conditions on the efficacy of seam penetration in the dyeing of cotton with reactive dyes†

Abstract

In a previous report, the development of an instrumental method for the quantitative assessment of seam penetration by reactive dyes was described. This paper now reports the use of this instrumental protocol to evaluate the effect of processing variables, especially temperature, pH and dye concentration, on the efficacy of seam penetration in the dyeing of cotton with reactive dyes. A simple approximate relationship has been established between the migration index of a reactive dye to its ability to penetrate seams efficiently.
