Abstract

The invention relates to a preparing method of a high-temperature levelling agent, and belongs to the technical field of spinning. According to the preparing method, diisopropanol amine and dimethylolpropionic acid are taken as mixed monomers and react with cyclodextrin and the like, a catalyst is adopted for catalysis, a hyperbranched polyester block cyclodextrin substance is formed, a very largecavity is formed in the formed hyperbranched polyester, and many active hydroxide radicals are formed on the surface of the hyperbranched polyester; then the hyperbranched polyester is mixed with a modifying agent formed by butanedioic anhydride and lysine, under the effect of the modifying agent, the content of carboxyl groups on the surface of the polymer can be increased, and the activity is improved; afterwards, glycerinum, cardanol and the like are mixed, and under the effect of a catalyst A, a cardanol-like glyceryl ether substance is formed; finally, the cardanol-like glyceryl ether substance is mixed with the polymer, dimethylformamide, an auxiliary material, an auxiliary agent and the like, wherein the polymer is utilized for triggering a reaction to form polymer-amphiphilic hyperbranched cardanol polyglycidol, and besides, through the utilization of the auxiliary material and the auxiliary agent, the types of active groups can be increased. By means of the preparing method,the problems that current levelling agents have a poor levelling effect and are hard to degrade are solved.

Description

technical field [0001] The invention relates to a preparation method of a high-temperature leveling agent, which belongs to the technical field of textiles. Background technique [0002] Polyester fiber is the most widely used synthetic fiber with the largest output. Due to the tight structure and strong hydrophobicity of the polyester polymer that makes up the polyester fiber, it cannot be dyed under normal pressure like other fibers, but must be dyed at high temperature with disperse dyes. In addition, in order to save resources and further improve labor productivity, the rapid dyeing method of polyester is often used, but rapid dyeing is often not easy to level dye, and it is necessary to add a leveling agent with excellent dispersibility to prevent the dye from agglomerating and have excellent dye migration. performance. The different physical forms of dyes have a great influence on their solubility in water and high-temperature dispersion stability, and directly affec...
