Also known as polypropylene fiber, is the high temperature after melting by spinneret and external annular transverse blowing system composed of spinneret spinning system, and then through the barrel, drafting, crimping, cutting and other processes made. Polypropylene fiber has high strength, good elasticity, abrasion resistance, corrosion resistance, electrical insulation and heat preservation, but poor stability to light and heat, hygroscopicity and dyeing.
