Technical Field

The invention relates to the technical field of dispersants for textile chemical industry, in particular to a glossiness dispersant for textile dyes and a preparation method thereof.

Background

With the continuous development of economy, the textile dye industry has become a bottleneck for restricting the development of the textile industry in China more and more obviously in the call of China for changing the textile country into the textile country. Therefore, the development of dyes is more highly concerned by those skilled in the art. The dye industry is the traditional fine chemistry industry, and products are mainly used in the textile printing and dyeing industry. In recent years, the dye yield in China is rapidly increased, the dye varieties are greatly developed, up to now, the number of the producible dye varieties in China is over 1200, the number of the frequently produced dye varieties is also 600-700, and more than 100 varieties of dyes comprise direct dyes, reactive dyes and acid dyes. In recent years, the development speed of new dye varieties is obviously accelerated, and all produced dye categories abroad are put into industrial production in China.

In the textile printing industry, most dyeing and printing processes involve the use of disperse insoluble dyes, and therefore dispersants are required in the manufacture and use of these dyes. A conventional dispersant is a surfactant having both lipophilic and hydrophilic properties in the molecule. The amphiphilic agent is capable of uniformly dispersing solid and liquid particles of inorganic and organic pigments which are difficult to dissolve in liquids, and also preventing settling and agglomeration of the particles to form stable suspensions. The stability of disperse dyes in aqueous dispersions is mainly obtained by the physical modification of the interface of the dye particles by the dispersant, which includes wetting of the solid surface, cleavage and coalescence of the particle groups, and prevention of reaggregation of the dispersed particles. However, the dispersing agent used for textile printing and dyeing in the prior art has the disadvantages of poor glossiness and stability, large solubility difference in water bodies with different pH values, and difficulty in stabilizing the dispersing effect.

In view of the above, we propose a gloss dispersant for textile dyes and a method for preparing the same, which addresses the above-mentioned problems.
