Problems solved by technology

At the same time, the whiteness, breaking strength, and wrinkle recovery angle of the cotton fabric after finishing are all tested. Compared with the unfinished cotton fabric, the whiteness is slightly reduced, while other properties remain basically unchanged, which is the closest to the present invention. There is technology, but the water solubility of its synthesized UV-DTHM is very poor, resulting in the reduction of the perspiration and moisture removal capacity of the cotton fabric after finishing. It has reactive groups and good water solubility to enhance its application range and wide use

Abstract

The invention discloses a method for preparing a moisture absorption and sweat releasing anti-UV finishing agent for pure cotton fabrics, belongs to the technical field of textiles and chemicals. The preparation method of the invention is green, environment-friendly, healthy and efficient; a prepared finishing agent solution is mild and non-irritant, and can be directly used for finishing fabrics; the finishing agent of the invention is used for finishing the pure cotton fabrics in a padding-steaming manner, gives the pure cotton fabrics excellent UV resistance after finishing while ensuring that the pure cotton fabrics have excellent moisture absorption and sweat releasing properties and good washing resistance and are suitable for wearing when working and living outdoors in hot seasons, also has less influence on the pure cotton fabrics after finishing while essentially remaining the whiteness, breaking strength and wrinkle recovery angle unchanged in comparison with unfinished cotton fabrics, can satisfy people's favorite to the pure cotton fabrics, and has a good market promotional value.

Description

Technical field: [0001] The invention discloses a preparation method of a moisture-absorbing, sweat-wicking and anti-ultraviolet finishing agent for pure cotton fabrics, belonging to the technical field of textile chemicals. Background technique: [0002] When ultraviolet rays irradiate the fabric, part of it is absorbed, part of it is reflected, and part of it is transmitted. In general, transmittance + reflectivity + absorptivity = 100%. Therefore, as the absorptivity and reflectivity increase, the transmittance decreases and the protective performance Just superior. The mechanism of anti-ultraviolet radiation is to use ultraviolet absorbers or ultraviolet shielding agents to protect the human body by absorbing or reflecting ultraviolet rays. [0003] The processing methods of anti-ultraviolet textiles are mainly divided into two categories. One is to mix ultraviolet absorbers or shielding agents into the spinning solution for spinning or to spin together with the spinnin...
