Abstract

The invention relates to a cationic modifier for pretreatment of textile products and a synthesizing method thereof. The cationic modifier comprises a component A, a component B and a component C, wherein the component A comprises the following components in parts by weight: 146 to 1460 parts of 3-chloro-2-hydroxypropyl-trimethylammonium chloride, 53 to 530 parts of polyhydric alcohols, 300 to 3000 parts of solvent, and 2.4 to 24 parts of alkaline catalyst; the component B is isocyanate; the component C is a thinner; the weight ratio of the component A to the component B to the component C is (200 to 2000):(250 to 2500):(1500 to 2400). Compared with the prior art, the cationic modifier has the advantages that the adding of alkaline for adjusting pH (potential of hydrogen) value in use is not needed; when the modified textile is dyed, the dyeing color is dark, the fastness is better, and the uniformity is better.

Description

technical field

[0001] The invention relates to the technical field of fine chemicals, and relates to a method for preparing a modifier for cationic surface modification of materials, in particular to a cationic modifier for textile pretreatment and a synthesis method thereof. Background technique

[0002] Textile cationic modifier is mainly used for the pretreatment modification of textile fibers, which can make negatively charged fibers cationic, improve the dyeing rate of dyes and paints during dyeing, and have the effect of deepening and brightening, thus saving The amount of dye and paint used.

[0003] Generally, the dyes and paints used in textile dyeing have negative charges, and the textiles are also negatively charged before modification, so when dyeing textiles, the utilization rate of dyes and paints will not be very high, especially in Yarn dyeing and pigment dyeing, when dyeing garments. In order to use dyes and coatings more efficiently and reduce water poll...
