Abstract
As the polyester fiber becomes thinner, thermomigration that is the most important factor deteriorating the washfastness, is more dominant. For improving the washfastness of ultrafine polyester dyed with disperse dye, it is necessary either to decrease the amount of thermomigrated dyes on the fiber surface, or to use a disperse dye containing diester group in the coupling component. This paper is concerned to investigate the relation between the chemical structure of three disperse dyes and their dyeing properties and washfastness. The disperse dye whose molecular size is big, can dye ultrafine polyester with good build-up, and its washfastness is reasonably good. Other disperse dye which has diester group, shows the same dyeing properties as the standard disperse dye, and its washfastness is better than that of the standard disperse dye.
