AI Technical Summary

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 discloses an accelerating agent for polyester blended fabric printing and dyeing and a preparation method thereof. The accelerating agent is mainly prepared from smectite powder, shikakai powder, guar gum, succinic anhydride cyclodextrin, an acid-base regulator, an emulsifier and a dispersing agent. After the accelerating agent is added, no sodium sulfate needs to be added, so that the application amount of salt in the printing and dyeing process is greatly lowered, the application amount of water is also decreased, and environmental protection is promoted; the added shikakai powder, guar gum and acid-base regulator are natural plant extracts, the smectite powder is natural mineral, and only a small quantity of the emulsifier and a small quantity of the dispersing agent are added, so that the environment-friendly performance is good; the accelerating agent is environmentally friendly, capable of saving water, good in dyeing effect, capable of being applied to the cotton and polyester blended fabric, high in color uniformity and high in soaping fastness.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a dyeing accelerator for printing and dyeing cotton-polyester blended fabrics and a preparation method thereof. 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 chlori...
