Method for preparing conductive wool fabric by using mercaptoacetic acid solution

Abstract

The present invention provides a method for preparing conductive wool fabric using thioglycolic acid solution, the method comprising the following steps: (1) Preparation of solution: adding thioglycolic acid, lithium chloride and sodium lauryl sulfate into water to form Mix the solution, adjust the pH value to 9-10 with sodium hydroxide, adjust the pH value to 9-10 with sodium hydroxide, then add conductive nano particles to the solution, and obtain a solution dispersed with conductive nano particles under ultrasonic vibration; ( 2) Padding the woolen fabric in the solution obtained in step (1) multiple times; (3) steaming the padded woolen fabric; (4) soaking the steamed woolen fabric in an aqueous solution of polyvinyl alcohol solidified in the middle, then washed and dried. The preparation technology is simple and easy, with low cost, little damage to the strength of the wool fabric, does not change the surface properties of the wool fiber, and the nano-conductive particles have good fastness on the wool fabric; no adhesive is used in the preparation process, and no Poison is harmless.

Description

technical field [0001] The invention relates to a method for preparing functional fabrics, in particular to a method for preparing conductive 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.
