Problems solved by technology

[0003] The invention patent with the application number of prior art 200810060886.3 discloses a fiber darkening agent emulsion and its preparation method, but this technology is mainly for polyester fiber for darkening treatment, because it contains cationic emulsifier of quaternary ammonium salt type, while real silk Fabrics are generally dyed with acid dyes. Acid dyes are water-soluble dyes. Most of the acid groups exist on the dye molecules in the form of sulfonic acid sodium salts. Only a few species exist in the form of carboxylic acid sodium salts. The dye is an anionic dye, generally cannot use additives containing cationic emulsifiers, so the use of this darkening emulsion for silk fabric darkening is limited
[0004] The invention patent with the application number of the prior art 201010288531.7 discloses a dyed cotton fabric darkening and brightening finishing agent and a preparation method, but this technology is mainly used for the darkening and brightening treatment of cotton fabrics. agent, the use of darkening silk fabrics is limited
[0005] For this reason, our research group has made in-depth research on the darkening of silk fabrics for many years, using various methods, and published related papers "Preparation and Application of Silicone Acrylate Darkening Agent" and "Printing and Dyeing Auxiliaries" in 2006 In the 08th issue, the authors Gao Zhenghong and Xie Hongde, one of them used silicone monomers and acrylates for emulsion polymerization, and prepared silicone acrylate emulsions in one step, through blue 16 electric spinning, black 03 crepe chine and other silk products After deepening, it is found that satisfactory results have been achieved, but there is still a shortcoming that the hydrophilicity decreases after deepening treatment, especially for heavy silk fabrics

Abstract

The invention discloses a silk fabric darkening agent copolymer emulsion and a preparation method thereof. The silk fabric darkening agent copolymer emulsion comprises the following raw materials by weight percent: 2-8% of methyl acrylate monomers, 6-16% of butyl acrylate monomers, 0.1-1.5% of an anionic surfactant, 0.1-1.5% of a non-ionic emulsifier, 0.01-0.1% of an initiator, 0.8-5% of a mono-amino-containing silane coupling agent, 5-15% of a vinyl-containing silane coupling agent, 0-1% of a silane hydrolysis inhibitor and 50-70% of deionized water. The silk fabric darkening agent copolymer emulsion disclosed by the invention is small in particle size, low in emulsifier dosage, and easy to control in the reaction process and causes no pollution to environment, the darkening rate of a thin and light silk fabric processed by the copolymer emulsion is close to 10% and the hydrophily is basically unchanged, while the darkening rate of a thick and heavy fabric is close to 16% and the hydrophily is slightly reduced. The silk fabric darkening agent copolymer emulsion has the characteristics of darkening and brightening, good washing durability, smooth handfeel and the like.

Description

technical field [0001] The invention belongs to the field of textile auxiliaries, and specifically relates to a silk fabric darkening agent copolymer emulsion and a preparation method thereof. Background technique [0002] In recent years, due to the prohibition of a batch of non-environmentally friendly dyes, in the domestic textile market, the depth of color of the dark fabrics that people liked is inferior to the original fabrics, especially in the fact that the fabrics are not dark and black. Someone once increased the amount of dyestuff to more than 10% of the original amount, but it didn't help. On the contrary, it brought about the decline of dyeing fastness and the increase of cost. Therefore, using additives and surface treatment methods to change the surface characteristics of the fiber and minimizing the amount of reflected light of the fiber is an effective way to improve its dark color performance. [0003] The invention patent with the application number of pr...
