DOCUMENT TYPE: Journal CA Section: 40 (Textiles and Fibers) Effects of the chem. structure of disperse dyes applied to conventional and microdenier polyesters on the dyeing properties and washfastness were studied. It was found that the washfastness is closely related to the degree of thermal diffusion of the dye during heat-setting.Several substances with their cas registry numbers 173957-22-7 and 30124-94-8 may be metioned in this study. A bulky disperse dye, which was synthesized by replacing the two acetoxy groups of C.I. Disperse Red 82 with two benzoyloxy groups, showed almost the same amt. of absorbed dye on the microdenier polyester as C.I. Disperse Red 82 itself, but the degree of thermomigration was low and subsequent washfastness was excellent. The high grade of washfastness of the bulky disperse dye might be caused by increased dye-fiber interaction and reduced mobility. .
