The Impact of Acid Blue Dye Concentration on Color Strength and the Chromaticity Coordinates of Raw and Tannery Wool: A Comparative Study

Globally, the management of wool waste employs a range of strategies and practical techniques to maximize the value of wool fibers in both clothing and non-clothing applications. Recent studies have emphasized the importance of wool waste valorization in establishing a new supply chain for tannery companies. To utilize wool fibers in clothing, interior textiles, and technical textiles, it is necessary to first dye and finish them. The aim of this research was to investigate the effect of acid dyes on tannery wool. In order to properly assess the colorfastness of tannery wool, this study compared the chromaticity coordinates and color strength with those of raw wool. Samples of both raw and tannery wool were dyed with an acid dye and subjected to analysis of K/S values. The results demonstrated that although the dyeing properties of tannery wool were lower than those of raw wool, the latter possessed considerable potential that could be developed for use in textile products. Tannery wool fibers are now being promoted as a sustainable and eco-friendly alternative material.
