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.展开更多
