Problems solved by technology

Acid dyes have had their heyday, but their dyeing fastness to wool is poor, and the dyeing acid is too strong, causing damage to fibers and serious environmental pollution, and a considerable part of them are prohibited dyes, and their consumption is showing a downward trend
Later, 1:1 metal complex dyes, 1:2 metal complex dyes and reactive dyes for wool were developed successively. In recent years, it was proposed to dye wool with disperse dyes, and the application of auxiliaries to promote cationic dyes to dye wool; although these The dyes developed later can solve some old problems, but at the same time it also brings new problems, mainly 1:1 metal complex dyes cause great damage to fibers; 1:2 metal complex dyes have poor levelness and incomplete chromatogram; in recent years Although the developed reactive dyes for wool have the advantages of high color fixing rate, good color fastness, and increased varieties, their level dyeing property is very poor. Due to the different dyeing properties of wool tip and hair root, the solution is uneven, and the dye is irreversible. The dyeability hinders the dissolution and diffusion process, and the unevenness cannot be improved through dye migration. In addition, the price of the reactive dyes used is relatively high, so it is difficult to promote their use
Disperse dyes have almost no directness to protein fibers, and the application of auxiliaries can promote disperse dyes to dye wool, but the wet fastness of dyed wool is very poor
Cationic dyes are a kind of water-soluble dyes, which are mainly used for dyeing acrylic fibers. They have the advantages of complete color spectrum, bright color, excellent wet fastness, high coloring rate, "good quality and low price", but it is difficult to use them in hydrophilic Direct dyeing of permanent natural protein fibers, although some people use auxiliary agents to dye cationic wool, but at the same time it also increases the cost of dyeing and increases the complexity of the dyeing process, and has not been officially popularized and applied.

Abstract

The cationic dye for dyeing and finishing wool and silk textile contains compound with structure as shown. The dye has sym-triazine compound as core, which has one end connected to color part in ion bond form and the other end with radical capable of reacting with the amino in wool and other protein fiber to reach dyeing effect. The dye is used for dyeing and finishing wool and silk textile and blending wool and silk textile and has bright color, high color fastness, simple dyeing and finishing process, and environment friendship.

Description

technical field [0001] The invention relates to a cationic dye used for dyeing and finishing woolen silk textiles. Background technique [0002] At the beginning of the last century, there were four types of dyes used for wool fibers: acid dyes, mordant dyes, chrome mordant dyes, natural and vat dyes. Among these dyes, chrome mordant dyes have caused serious environmental pollution due to their dull dyeing color, so their market usage has declined since the 1950s. The output of natural dyes is small, the variety is small, and the production process of vat dyes is complicated. Therefore, these three types of dyes have been eliminated successively. Acid dyes had a heyday, but their dyeing fastness to wool is poor, and the dyeing acid is too strong, causing damage to fibers and serious environmental pollution, and a considerable part of them are prohibited dyes, and their consumption is showing a downward trend. Later, 1:1 metal complex dyes, 1:2 metal complex dyes and reacti...
