Popis:	The recently developed mordant SCA-Cr has been employed in mill production for the afterchrome dyeing of cashmere for more than two years, and about 80 tonnes of the fibre has been dyed in this way. The mill results confirmed the value of the Cr(III)-containing mordant and the new technique has replaced the conventional chrome dyeing method, in which dichromate was employed as the mordant, in three biggest cashmere processing companies in China. The concentration of Cr(VI) in the residual dyebath was greatly decreased (to less than 0.01 mg/l). Because of the reduced oxidation damage to the cashmere during mordanting, the spinning properties, as well as other properties, of the loose cashmere stock were significantly improved and the quality of the final products was greatly enhanced.
