Polyimide woven cloth and preparation method thereof

Abstract

The invention discloses a polyimide woven cloth and a preparation method thereof. The materials of the polyimide woven cloth comprises 45-70% of polyimide fiber iron aramid wire, 10-25% of cashmere, 10-25% of wool, and 5-10% of other ingredients, wherein the other ingredients are at least one of the ingredients such as cotton, flax, tencel, modal, bamboo charcoal fiber, spun silk, silk, viscose rayon and polyester. The preparation method comprises the following steps of material synthesizing and choosing, flock dyeing, fiber mixing, fiber carding, doubling and twisting, panel knitting, finishing and the like. The polyimide woven cloth which is prepared by blending in different proportion has the advantages of being high in temperature resistance, strong in bursting resistance, fireproof, flame-retardant, ultraviolet-proof, soft, and anti-pilling. Compared with the conventional multi-function finishing fabrics, production technology and post-treatment technology are simplified greatly, and production efficiency is improved.

Description

technical field [0001] The invention relates to a polyimide woven fabric and a preparation method thereof, belonging to the technical field of textiles. Background technique [0002] Traditional woven fabrics are usually composed of natural fibers, synthetic fibers or their blends. They are not strong in breaking resistance, easy to loose, and have weak anti-ultraviolet and fire-proof capabilities. The multi-functional finishing process is complicated and costly; while polyimide The fiber is a new type of special fiber. The molecular chain contains aramid rings. The fiber has the advantages of high strength, high modulus, high temperature resistance, flame retardancy, radiation protection, and chemical corrosion resistance. It is used in the atomic energy industry, space environment, Aerospace, national defense construction, fire-fighting equipment, sports equipment and many protective equipment have good application prospects. Contents of the invention [0003] In order ...
