Embodiment 1
[0018] Example 1 High-temperature and high-pressure dyeing encapsulated Disperse Blue S-3BG 0.08 g distilled water 100 g Dye 3 g of pure polyester fabric on a high-temperature and high-pressure dyeing tester at 120°C for 1 hour (rising to 90°C within 8 minutes, then 1°C / min to 120°C, keep warm for 1 hour), cool down, discharge, wash with water, and after the waste liquid stands for 2.5 hours, the absorbance of the upper clarified liquid is zero (620nm), and the dyed sample obtains a uniform brilliant blue color.
Embodiment 2
[0019] Example 2 Heat-melt dyeing encapsulated Disperse Blue S-3BG 0.8 grams of sodium alginate 2 grams of JFC 4 grams of distilled water 200 grams of double immersion and second rolling, the liquid carrying rate is 80% - drying - high temperature color development (220 ° C * 2 Minutes)—washing—drying, the washing solution was allowed to stand for 2.5 hours, the absorbance of the precipitation solution was zero (620nm), and the sample was uniform light blue.
Embodiment 3
[0020] Example 3 Multiple transfer printing of encapsulated dye 2.4 g of 1% sodium alginate solution 20 g of JFC 1 g of urea 2 g to make printing paste The printing paste is printed on kraft paper and dried to make transfer paper. Transfer printing: transfer 10 times on pure polyester silk at 190°C for 20 seconds, and get 10 samples with basically the same K / S value.
