Problems solved by technology

[0002] Traditional knitted 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 complex and costly; while polyimide fibers It is a new type of special fiber, which contains aramid rings in its molecular chain. 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 atomic energy industry, space environment, and aviation. Aerospace, national defense construction, fire-fighting equipment, sports equipment and many protective equipment have good application prospects

Abstract

The invention discloses a polyimide knitted fabric and a preparation method thereof. The preparation method comprises the steps of loose wool dyeing, wool mixing, wool carding, doubling and twisting, panel knitting, after finishing and the like; a gray fabric is prepared by weaving blended yarn of polyimide, wool, cashmere, spandex, nylon, acrylic fibers and polyester (or modified polyester) fibers. The knitted fabric prepared by blending the raw materials of different proportions has the advantages of being capable of resisting high temperature, high in bursting strength resistance, capable of resisting fire, retarding inflaming and resisting ultraviolet, soft, not prone to pill and the like, and compared with a conventional multifunctional finished fabric, the production and aftertreatment processes are greatly simplified, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a polyimide knitted fabric and a preparation method thereof, belonging to the technical field of textiles.
