Preparation and Application of Microencapsulated Disperse Dyes

Microcapsules containing disperse dyes were prepared by means of in-situ polymerization. Polyester fabrics were multiple-transfer printed and color-mix printed using those microencapsulated dyes under different process conditions. By color measurement instrument, it can be seen that the times of multiple-transfer printing are up to ten while under appropriate conditions, especially when the transfer printing time is 50 seconds and the transfer printing temperature is 180° C. On the other hand, the K/S value of each transfer printing can keep almost constant. Meanwhile, the visual effect of color-mix printing with microencapsulated disperse dyes is special in the varicolored exhibiting if compared with conventional disperse dyes.
