Microencapsulated disperse dyes for combination dyeing

In order to study the dyeing properties and select the optimum color matching of the microencapsulated disperse dyes for combination dyeing,C.I.Disperse Red 73,C.I.Disperse Yellow 211 and C.I.Disperse Blue 183 were chosen to be microencapsulated.The ratios of the core to wall were changed during the course of microencapsulation so as to control the release rate of the disperse dyestuff.Meanwhile,the related dyeing properties of the microencapsulated disperse dyes were studied respectively,such as dyeing curves,up-take rate,levelness and build-up.Based on the results,the optimum mixing of the microencapsulated disperse dyes for combination dyeing in absence of auxiliaries,was found out.Then it was applied to combination dyeing of black shade,and the dyeings exhibited rather good levelness,dry rubbing fastness and washing durability.
