Problems solved by technology

People know through research that the salt effect of monocarboxylates is stronger than that of NaCl, and polycarboxylic acids are stronger than monocarboxylates. If they are used instead of table salt and Yuanming powder, the amount of salt can be greatly reduced, but the price of these so-called substitute salts is the same at present. Table salt and Yuanmingfen are too expensive compared with each other, so they cannot be promoted and applied

Abstract

The invention relates to a printing-dyeing method of environment-friendly cotton textiles. According to the printing-dyeing method, a dyeing accelerating agent with a good effect is prepared by compounding expanded vermiculite powder, gelatin and guar gum with organic acid, the hydration degree of active dyes can be effectively reduced, and the dyeing accelerating agent can be used for completely replacing anhydrous sodium sulphate in use, so that the consumption of salt is greatly reduced in the printing-dyeing process, and meanwhile, the consumption of water and sodium carbonate is reduced, thereby being beneficial to environmental protection.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to an environment-friendly cotton textile printing and dyeing method. Background technique [0002] Cotton fiber occupies an important position in the textile industry, accounting for about 65% of the total fiber output. The most important and most potential dyes currently used in cotton fiber dyeing are reactive dyes. Reactive dyes are combined with cotton fibers through covalent bonds, fundamentally solving the problem of poor wet fastness of dyed fibers. At the same time, because reactive dyes have the advantages of complete chromatogram, bright color, simple application process, strong applicability, and relatively cheap price, they have become the dyes with the largest output and output value among dyes for cotton fibers in recent years. In the traditional reactive dyeing process, a large amount of sodium chloride or sodium sulfate must be added. When salt...
