APPLICATION OF CELLULOSE PROCESSING BY-PRODUCTS IN THE CHROME DYEING OF WOOL FIBER
Abstract
Application of cellulose processing by-products (lignin sulfonates) appeared to be high-effective for the chroming process in the wool fiber dyeing. Lignin sulfonates show affinity to wool. They have higher reductivity than keratin and chrome dyestuffs. Addition of lignin sulfonates to the dyeing baths increases the dyeing speed (1,3–1,5 times), increases the evenness of the dyeing (1,6–3,4 times), increases colour yield (by 4–5%) and decreases the tensile strength losses of the wool fiber. The developed dyeing process leaves 4–5 times less residual Cr (VI) in the dyeing baths, and utilizes cellulose processing by-products – that works for ecological improving of both wool dyeing and cellulose processing.Downloads
