Abstract

The invention provides a polyester disperse dye in-situ mineralization dyeing process, and belongs to the technical field of textiles. The polyester disperse dye in-situ mineralization dyeing processcomprises the following steps: adding dyeing water into dyeing equipment, and keeping dye bath circulation; then dyeing the terylene by using a disperse dye and a high-temperature and high-pressure dyeing method; carrying out first-stage in-situ mineralization treatment on the residual dyeing bath and the dyed polyester by using two disperse dye dyeing post-treatment assistants at the same time; taking out the polyester, soaking the polyester with a propyl alcohol solution, irradiating the polyester with ultraviolet radiation, adding a third disperse dye dyeing post-treatment auxiliary agent to carry out two-stage in-situ mineralization treatment, and finally completing the subsequent treatment process. The invention also discloses a preparation method of the three disperse dye dyeing post-treatment assistants for the in-situ mineralization dyeing process. Due to the application of the in-situ mineralization dyeing process, the emission of processing water and pollutants is reduced.

Description

technical field [0001] The invention relates to a dyeing process, in particular to an in-situ mineralization dyeing process of polyester disperse dyes. Background technique [0002] The annual water consumption of my country's textile industry exceeds 10 billion tons, and the waste water discharge ranks sixth among all industries in the country. Among them, the water consumption of the printing and dyeing industry accounts for 80%, about 8 billion tons, and the water consumption per unit of textile quality is 2~2 that of foreign developed countries 3 times, and the unit energy consumption is 3 to 5 times that of theirs, so energy saving, water saving, and emission reduction are urgent issues in the printing and dyeing industry. [0003] Polyester (polyester fiber) is usually dyed with disperse dyes. After dyeing, there will be more dyes and auxiliaries that have not been dyed and fixed, which increases pollution discharge. In order to ensure the color fastness of the product...
