Abstract

The invention discloses an antistatic fabric preparation method, which comprises: preparing a chitosan solution, preparing a chitosan cross-linked modified polyacrylate emulsion, preparing fibers by using a solution spinning method, carrying out cluster induction on the fibers, and twisting to prepare yarns; preparing master batch by using a polyamide resin, carbon nano-tubes, calcium carbonate and sodium chloride as raw materials, mixing the master batch and a polyamide resin, carrying out melt spinning, treating the prepared fibers by using an acid, drying, plying with fibroin fibers, and twisting to prepare yarns; weaving by using the prepared yarns as raw materials to prepare a fabric; and treating the fabric by using a modification liquid to prepare the antistatic fabric, wherein themodification liquid comprises modified hornblende schist powder, a polyamide resin, water, a dispersing agent, a thickener and a leveling agent. According to the present invention, the operation of the method is simple, and the prepared fabric has advantages of excellent mechanical property, good antistatic property and good gas permeation.

Description

Technical field: [0001] The invention relates to the field of fabric preparation, in particular to a preparation method of an antistatic fabric. Background technique: [0002] The rapid development of science and technology and the emergence of various electronic products have facilitated people's lives and at the same time produced many negative problems, such as static electricity and electromagnetic waves. The accumulation of static electricity and the radiation of electromagnetic waves will affect the operation of machines and damage people's health. . [0003] Static electricity is very harmful to the human body. Long-lasting static electricity can increase the pH value of blood, increase blood sugar, reduce calcium content in serum, increase calcium excretion in urine, and reduce vitamin C content. Excessive static electricity accumulates in the human body, which can also cause abnormal current conduction of the brain nerve cell membrane and affect the central nervous...
