Abstract

The invention relates to a method for improving the pad dyeing fixation rate of a textile, and belongs to the field of textile printing and dyeing processing. According to the method provided by the invention, the proportioning of a dye solution and a fixation solution in a textile pad dyeing process is changed, the textile is pad-dyed and dye-fixed respectively using the dye solution or the fixation solution, which is prepared by mixing an alcohol organic solvent in high proportion, a little water, and a dye or a fixing agent, so that the pad dyeing fixation rate of the textile is improved. By adopting the method for improving the pad dyeing fixation rate of the textile provided by the invention, in the pad dyeing process of the textile, not only can the hydrolysis rate of the dye in the dye solution be reduced to improve the utilization rate, the dye-uptake rate, and the even dyeing rate of the dye and the fixation rate of the textile, but also the problem of high water consumption in the textile pad dyeing process can be greatly reduced, as well as the dosage of an auxiliary can be effectively reduced. The method provided by the invention is simple in process, and low in cost, and the alcohol organic solvent can be recycled, is safe, energy-saving, economic and environment-friendly.

Description

technical field

[0001] The invention relates to a method for improving the color fixation rate of textile pad dyeing, which belongs to the field of textile printing and dyeing processing. Background technique

[0002] The dyes used in the conventional pad dyeing technology generally have many advantages such as bright colors, complete chromatograms, pure shades, excellent fastness, low price, and convenient use. However, the biggest problem with these dyes in application is that the dye utilization rate is not high. , the color fixing rate is only 60~70%, and a large amount of additives are consumed in the pad dyeing process, which causes great pollution to the environment. Therefore, how to improve the pad dyeing fixation rate of dyes has become a hot spot of research at home and abroad.
