In recent years, with the improvement of the living standard of people, the demand of textiles is increasing, and the demand of textiles is also increasing, such as the requirements of colorful textiles, good color fastness and the like. As a representative of the modern dye industry, the reactive dye is favored by the printing and dyeing industry because of the advantages of bright color, complete color spectrum, economical process, simple operation, good leveling property, lower price and the like. However, reactive dyes have their own disadvantages which are difficult to overcome, their color fastness is relatively poor when dyeing deep colors, and finishing with fixing agents to improve the color fastness is an important measure. Reactive dyes, although forming functional covalent bonds between the dye and the fiber, can have reduced color fastness if the dye is hydrolyzed during dyeing or if the dye is insufficiently soaped, the dye falls off the dyed wet fiber. Not only lightens the color of the fabric, but also stains white or dyed fibers with other colors to generate staining and overlapping phenomena. In order to solve the problems, the development of novel dyes with high absorptivity, high fixation rate and high fastness is greatly effective, but the development of novel fixing agents is synchronous.
