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 environment-friendly type dyeing assistant for natural blended fabric. The environment-friendly type dyeing assistant is mainly prepared from the following main raw materials: a rare earth compound, organic acid, borax, chitosan, a leveling agent, a dispersant, zinc oxide and sodium hexametaphosphate. In the environment-friendly type dyeing assistant, the main raw materials are the borax and the sodium hexametaphosphate, and a trace of the rare earth compound and a small amount of the zinc oxide are supplemented, so that the content of inorganic salt is reduced to be less than 1 percent, and environmental hazard is remarkably reduced; meanwhile, during a preparation process, compounds, such as halogens and heavy metal, which are harmful to a human body and the environment are not added. The environment-friendly type dyeing assistant disclosed by the invention is matched with active dye for use, and dyed natural blended fabric is uniform in color, has no chromatic aberration, is bright in color and good in color fixing effect.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to an environment-friendly dyeing aid agent for natural 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 chloride or sod...
