Problems solved by technology

[0004] After the cationic polymer film is formed, the emulsifier in it will absorb water in the water environment, causing the film to swell or the emulsifier to precipitate and cause pores, which weakens the same-color effect of the color-fixing agent and reduces the fastness of the fabric

Abstract

The invention relates to a cation formaldehyde-free dye-fixing agent emulsion. The cation formaldehyde-free dye-fixing agent emulsion is prepared by performing soap-free emulsion polymerization on a cation polymerizable emulsifier, a silicon-containing cationic monomer, a silane coupling agent, an initiator and deionized water which are used as raw materials. The cation formaldehyde-free dye-fixing agent emulsion overcomes the problems that after the current cation formaldehyde-free dye-fixing agent polymer forms a film, the hole can be formed because the film can be swelled or the emulsifier can absorb water in the water environment and can be separated out, the fixation effect of the dye-fixing agent can be weakened and the fastness problem of the fabric is reduced. The dye-fixing agent emulsion provided by the invention has good film forming ability and high cationic density, reinforces the fabric crockfastness improving effect, avoids the harmful effect of the emulsifier on the emulsion film and improves the hand feel of the textile.

Description

technical field [0001] The invention relates to a cationic formaldehyde-free color-fixing agent emulsion, belonging to the field of printing and dyeing auxiliaries. 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] Quaternary ammonium salt color fixing agents, especially quaternary ammonium salt polymers with high cationic charge density, have better washing fastness, and also have good chlorine bleaching and perspiration fastness, no color change and light fastness decrease And so on. [0004] After the cationic pol...
