Polypropylene is a product of polypropylene fiber, it is made of acrylic material by polymerization and melt spinning of fibers. Polypropylene officially beginning industrial consumption in 1957, is a rising star in synthetic fiber. Because polypropylene technology briefly, with consumption products and low price, high strength, light strengths, such as relative density polypropylene stretch quickly. Now polypropylene fiber is the fourth largest varieties of synthetic fiber. The consumption of polypropylene containing short fibers, yarn and split fiber etc. Polypropylene fiber membrane is polypropylene made film first, and then to end stretch film, unite it into the original fiber made by forming a mesh. Many polypropylene used for making industrial fabric and nonwoven fabric, etc., such as carpet, industrial filter cloth, rope, fishing nets, construction of strengthening materials, suction linoleum and decorative cloth, etc., in respect of civil polypropylene can be pure or with wool spinning, cotton and viscose blended to create all kinds of material. In addition, polypropylene fiber membrane can be used as packaging materials. Polyester is an important variety of synthetic fiber, is China’s polyester fiber products. It is a pure terephthalic acid (PTA) and dimethyl terephthalate (DMT) and ethylene glycol (EG) as the material through esterification and ester communication and polycondensation reaction of fiber forming polymer, polyethylene terephthalate (PET), after spinning and disposal made of fiber.
