Problems solved by technology

[0004] A general-purpose white-bottom anti-stick soaping agent for nylon, mainly composed of maleic anhydride-acrylic acid-N-vinylpyrrolidone terpolymer, which has good dispersion performance and can effectively prevent the floating color from returning to the nylon fabric during soaping. Sticky, but there are also prominent problems. The cleaning power is not enough, which leads to the floating color dyed by acid dyes on nylon fabrics cannot be removed cleanly, which affects the improvement of soaping fastness of nylon fabrics after dyeing.
[0005] In the Chinese patent whose publication number is CN102876476A, an acidic soaping agent is disclosed, which consists of carboxyethyl thiosuccinic acid, maleic acid-acrylic acid copolymer, ethylenediamine di-o-hydroxyphenyl acetate and defoamer Compounded, the soaping agent can save one pickling or several water washings, reduce the pressure of sewage treatment, and the maleic acid-acrylic acid copolymer used in it is low-cost, low-foaming, non-toxic and biodegradable, but There is still a considerable diff

Abstract

The invention discloses a white-ground anti-staining soaping agent for nylon and a preparation method of the white-ground anti-staining soaping agent. The white-ground anti-staining soaping agent for nylon comprises the following raw materials of 40-60 parts of a mixed monomer, 1-5 parts of a film-forming colloid, 1-5 parts of an emulsifier, 0.2-0.5 part of an initiator, and 25-40 parts of deionized water. The white-ground anti-staining soaping agent is prepared from vinyl acetate, acrylate and functional monomers as main raw materials by adopting an emulsion polymerization method under the combined action of the film-forming colloid, the emulsifier and the initiator. The white-ground anti-staining soaping agent for nylon has the advantages that the storage stability is good, the stiffness is superior to that of polyvinyl acetate and vinyl acetate-acrylic copolymer, the stiffness effect of urea-formaldehyde resin is achieved, and the soaping agent does not contain formaldehyde; and through modified copolymerization of the functional monomers, the washing resistance of the polyvinyl acetate, the vinyl acetate-acrylic copolymer and other series of products is obviously improved, the technical defects of the series of products are better overcome, and the development trend of stiffening and finishing agents in the market is met.

Description

technical field [0001] The present invention relates to the technical field of textile printing and dyeing, in particular to a white bottom anti-staining soaping agent for nylon and a preparation method thereof. Background technique [0002] Acid dyes are also called anionic dyes because they contain anionic groups in the dye molecules. It can be combined with the amino group in the nylon fiber molecule through ionic bonds, and can give nylon fabrics a bright color fastness. Acid dyes are divided into weak acid dyes and metal complex dyes according to their chemical structure and dyeing conditions. The degree of aggregation and solubility is medium, the affinity for nylon fibers is relatively high, the migration and level dyeing properties are slightly poor, the fastness to wet treatment is good, and it can be dyed in weakly acidic medium (pH 4-5), without damage to fibers. The shade is darker and the color fastness is average; metal complex dyes are soluble in water, have...
