Anti-ultraviolet wool fabric prepared from mercaptoacetic acid solution

Abstract

The present invention provides a method for preparing anti-ultraviolet wool fabric by using thioglycolic acid solution, the method comprising the following steps: (1) Preparation of solution: adding thioglycolic acid, lithium chloride and sodium lauryl sulfate to water, Form a mixed solution, adjust the pH value to 9-10 with sodium hydroxide, adjust the pH value to 9-10 with sodium hydroxide, then add zinc oxide nanoparticles to the solution, and obtain the dissolution of zinc oxide nanoparticles dispersed under ultrasonic vibration (2) padding the woolen fabric several times in the solution obtained in step (1); (3) steaming the padded woolen fabric; (4) impregnating the steamed woolen fabric in polyester Coagulate in vinylpyrrolidone aqueous solution, then wash with water and dry. The preparation technology is simple and easy, the cost is low, the strength damage to the wool fabric is small, the surface properties of the wool fiber are not changed, and the zinc oxide nanoparticles have good fastness on the wool fabric; no adhesive is used in the preparation process, toxic free and safe.

Description

technical field [0001] The invention relates to a method for preparing functional fabrics, in particular to a method for preparing anti-ultraviolet wool fabrics by using thioglycolic acid solution. Background technique [0002] Functional fiber materials can be prepared by introducing nanoparticles into textile fibers. At present, there are many preparation methods for introducing nanoparticles into wool fibers, such as: adsorption method, sol-gel method, layer-by-layer assembly method, coating method and so on. However, the adsorption method mainly uses the intermolecular van der Waals force and ionic bond force to make the nanoparticles adsorb to the surface of the wool fiber, and the washing fastness is low; the process of the sol-gel method and the layer-by-layer assembly method is long and difficult to control; The coating method is to use adhesives to bond nanoparticles to the surface of wool fibers, which reduces the skin affinity of wool fibers to the human body. ...
