Abstract

A microcapsule dyeing technology and apparatus without assistant and water washing is disclosed. Said apparatus is a by-pass linked to an ordinary high-temp and -pressure dyeing machine. Said by-pass consists of a microcapsule dye extractor, the water inlet and outlet tubes connected to microcapsule dye extractor and dyeing machine, and the valve for controlling the release of dye. The residual microcapsule can be easily separated from dyeing liquid.

Description

technical field [0001] The invention belongs to the field of light chemical industry, and furthermore relates to a microcapsule additive-free washing-free dyeing process and device, and a clean dyeing process and device. Background technique [0002] At present, the dyeing of disperse dyes is still the dyeing of water-based medium under the action of auxiliary agents, that is, the dyes are stably dispersed in water with the help of auxiliary agents, and dyed at a high temperature of 130 ° C. After dyeing, the surface of the fabric is washed with water, soaped and reduced The floating color is washed away to meet the predetermined fastness requirements. In order to save water, people use a small bath ratio for dyeing, the bath ratio is about 1:7, but the washing process is essential, so the water consumption for dyeing and washing per ton of fabric dyed is about 100-150 tons, and the waste water produced is seriously polluted. . In order to protect the environment, people u...
