The polypropylene product is a Chinese brand name of synthetic fiber isotactic polypropylene fiber obtained by using petroleum refining by-product propylene as a raw material. Also known as polypropylene fiber. The raw materials are abundant, the production process is simple, and the product price is relatively cheaper than other synthetic fibers. The physical and mechanical properties of the fiber are characterized by high strength (4-6 g/d for short fibers and 5-8 g/denier for filaments), wet strength and dry strength are basically the same, specific gravity is small (0.91), and wear resistance is resistant. Corrosion, etc. The annual production of polypropylene fiber in the world has exceeded 1 million tons in 1980.

The lines produced by Tengzhou Junchi Textile Co., Ltd. include: polypropylene yarn, pp multifilament yarn, nylon thread, PE thread, packaging line, cotton thread and so on.
