Problems solved by technology

[0006] From the 1930s to the present, the development of color fixing agents has experienced a process from non-environmental protection to environmental protection, from single to diversified. However, its research and development still cannot meet people's requirements, especially wet rubbing fastness, perspiration fastness, etc. In terms of strength and chlorine fastness, there is still a need for new and more effective products to appear

Abstract

The invention relates to a soap-free color-fixing agent emulsion and a preparation method thereof, which belongs to the field of textile chemistry. The emulsion is prepared mainly through the reaction of polymeric monomers, a dispersion stabilizer, cation-carrying monomers, crosslinking monomers, an initiator and deionized water. The soap-free color-fixing agent emulsion is a copolymer emulsion which is prepared by taking water-dispersible oligomer of the copolymerization of diallyl ammonium salt and hydrophobic monomers as the dispersion stabilizer, taking cationic diallyl ammonium and the like as comonomers, adding functional crosslinking monomers and performing soap-free emulsion polymerization under the action of a free radical initiator. The soap-free emulsion contains no conventional small-molecule emulsifier, and the emulsion has the advantages of excellent film-forming property, high cationic charge density, good color-fixing synergetic effect and capability of effectively promoting the color-fixing effect of fabrics.

Description

technical field [0001] The invention relates to a soap-free color fixing agent emulsion and a preparation method thereof, belonging to the field of textile chemistry. Background technique [0002] Anionic water-soluble dyes such as direct dyes, reactive dyes, acid dyes, etc., have a complete color spectrum and bright colors, and are widely used in the dyeing of cotton, nylon, and protein fiber fabrics. However, its wet fastness is poor, staining and fading are serious, and it is difficult to meet people's requirements for high-quality textiles. In order to improve the fastness of fabrics, it is generally necessary to carry out color fixing treatment after dyeing. [0003] The research on color-fixing agents began in the 1930s, and the first generation of color-fixing agents in the real sense was the dicyandiamide resin color-fixing agent produced in the 1950s. The color-fixing mechanism of this kind of color-fixing agent is to form color lakes with dye anions, which are ma...
