Abstract

The invention discloses a preparation method of a high-adhesion aqueous deepening agent, and belongs to the technical field of textile auxiliary preparation. Glycidyl is grafted onto the amino group of chitosan under an acidic condition to obtain a cationic adsorbent, an obvious adhesion buffering effect is achieved, the friction coefficient between fabric fibers can be effectively reduced, and ahigh-adhesion anti-corrosion film layer is formed. The anionic surfactant sodium lignin sulfonate used in the preparation method has a relatively large spatial structure, a relatively large steric hindrance can be generated in the high-adhesion aqueous deepening agent, the water-based dispersion performance of a dye can be improved, the deposition density of inorganic particles can be improved inthe later stage of curing by an adhesion promoting auxiliary agent, and the adhesion of the deepening agent film layer can be improved; and by virtue of added fel bovis and wetting agent, the wettingdegree and liquidity of the dye can be improved, the surface tension of water can be improved, the water can be prevented from forming water beads, an essential oil can accelerate the volatilization of a solvent, the curing of the deepening agent can be accelerated, and the moisture absorption performance of the fabric can be improved.

Description

technical field [0001] The invention discloses a preparation method of a water-based darkening agent with high adhesion, and belongs to the technical field of preparation of textile auxiliary agents. Background technique [0002] Darkening agent is an auxiliary agent used to improve the dyeing depth of disperse dyes on polyester fabrics. When natural fibers (such as silk) are dyed into dark colors, reactive dyes are often used to improve color fastness. In order to increase the color depth, it is generally achieved by increasing the concentration of the dye. However, the deepness of reactive dyeing is poor, and even when the amount of dye is as high as 6% (based on cloth weight), the color depth of the fabric still cannot meet the requirements, and thus the color fastness of dark fabrics is not up to standard, and the amount of dye is too large. Waste and increased burden on sewage treatment and many other issues. [0003] Fabric darkening refers to a finishing method tha...
