Problems solved by technology

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

Abstract

The invention provides a method for preparing far-infrared wool fabrics using a thioglycolic acid solution, the method comprising the following steps: (1) Preparation of a 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 tourmaline powder (above 600 mesh) into the solution, and obtain dispersed tourmaline powder ( 600 mesh or above) solution; (2) padding the woolen fabric in the solution obtained in step (1) several times; (3) steaming the padded woolen fabric; (4) steaming the woolen fabric The wool fabric is soaked in polyvinylpyrrolidone aqueous solution to solidify, then washed and dried. This preparation technology is simple and easy, with low cost, little damage to the strength of wool fabric, and does not change the surface properties of wool fiber. Tourmaline powder (above 600 mesh) has good fastness on wool fabric; no adhesive is used in this preparation process. Mixture, non-toxic and harmless.

Description

technical field [0001] The invention relates to a method for preparing functional fabrics, in particular to a method for preparing far-infrared wool fabrics 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.
