Functional fabrics refer to fabrics with certain special properties and uses, such as waterproof, windproof, breathable, moisture-permeable, warm, oil-proof, easy to decontaminate, antibacterial and deodorant, anti-ultraviolet, anti-static, anti-radiation, anti-blocking Fire, high temperature resistance, acid and alkali resistance and other functions. The functional fabrics on the market are mainly apparel fabrics, which are mostly used in outdoor sportswear and high-end casual wear. Among the new functional textile materials, polyester fiber is the most developed synthetic fiber.

The functional fabrics of microfiber fabrics are mainly obtained by the weaving method of functional fibers and the padding method of functional additives. The functional fiber manufacturing method refers to the use of high-performance fibers with special functions in the spinning stage, such as "carbon fiber, aramid fiber, aramid fiber, high-strength vinylon, High-strength and high-modulus polyethylene, polyphenylene sulfide (PPS), polybenzobisoxazole (PBO) and other high-performance fibers”, among which aramid fiber has high temperature resistance, flame retardant and high toughness, and can be made into various protective clothing, fire clothing and bulletproof clothing, etc. Functional additive padding method refers to the use of advanced coating technology to coat different chemical raw materials on the cloth surface to make it have special functions such as waterproof, flame retardant, antistatic, and enhanced strength. Commonly used coating materials are PU (polyurethane) coating, PVC (polyvinyl chloride) coating and PA (polyacrylate) coating.
