Abstract

The invention relates to a preparation method of a polyester fabric moisture absorption and sweat releasing finishing agent with a hydrophilic side chain, wherein the method comprises the following steps: with dimethyl terephthalate, ethylene glycol, polyethylene glycol, a self-made side chain hydrophilic diol and a catalyst as raw materials, carrying out transesterification, and carrying out polycondensation to synthesize the polyester-polyether copolymerization moisture absorption and sweat releasing finishing agent suitable for polyester fabrics. The method is high in synthesis efficiency,the finished fabric is good in hydrophilicity, high in comfort and good in washability, and the problem that an existing moisture absorption and sweat releasing agent cannot give consideration to hydrophilicity and washability at the same time is solved.

Description

technical field [0001] The invention relates to the technical field of moisture-absorbing and perspiration-absorbing finishing agents for polyester fabrics, in particular to a method for preparing a moisture-absorbing and perspiration-absorbing finishing agent that is applied to polyester fabrics and is both hydrophilic and washable, and the finishing prepared by the method agent. Background technique [0002] From the perspective of human body wearing comfort, people hope that sweat can be absorbed and transferred by clothing, and sweat can be evaporated quickly on the surface of clothing to keep the surface of the skin and the microclimate zone inside the clothing dry. , Summer clothing is particularly important. In recent years, as consumers pay more and more attention to comfort when purchasing clothes, the demand for moisture-wicking clothes is growing rapidly. Synthetic fibers have excellent properties that natural fibers cannot match, especially the most widely used...
