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.

Abstract

The present invention relates to a disperse microcapsule dyeing method. It adopts the disperse dyes microcapsule using di-or polyisocyanate compound or melamine resin prepolymer and ethylene monomer as microcapsule wall material to implement high-temp. high-pressure open-width dyeing, high-temp. high-pressure ropd dyeing, thermosol dyeing or multiple transfer printing treatment of polyester fabrics. The present invention has no need of dispersing agent, high-temp. level dyeing agent and other dyeing adjuvant.

Description

technical field [0001] The invention belongs to the technical field of light chemical industry, in particular to a method for dyeing microcapsules of disperse dyes. technical background [0002] Due to the extremely low solubility of disperse dyes in water, traditional disperse dyes are dyed with the help of a variety of auxiliary agents, such as dispersants, leveling agents, solubilizers, etc., so that disperse dyes can be dispersed in the dyeing medium water as evenly as possible. , and then dye the dyed object under appropriate temperature, pressure and other conditions. After dyeing, due to the presence of auxiliary agents, a considerable amount of dye remains in the dyeing wastewater. As a result, dyeing wastewater contains a large amount of COD, BOD and serious chromaticity pollution load. Residual dyes are very finely dispersed and stable in wastewater, so the treatment of such wastewater is very difficult. In the printing and dyeing industry, polyester and its ble...
