Polypropylene high strength wire production process!

Raw material selection: The selection of high-purity polypropylene pellets as the main raw material to ensure the basic performance of polypropylene high-strength yarn. Some manufacturers will also add some special additives, such as antioxidants, ultraviolet absorbers, etc., to further improve the performance of  Polypropylene high strength wire

Spinning process: one-step or two-step spinning process is often used. One-step spinning process has low energy consumption and high production efficiency. The breaking strength of the silk produced by the two-step process is high, which can reach 6-8cn/dtex. In the spinning process, it is necessary to strictly control the spinning temperature, pressure, drawing speed and other parameters to ensure the molding quality and performance of the fiber.

Post-treatment: including stretching, shaping and other processes. Stretching can make the molecular chain orientation of polypropylene fiber more regular, so as to improve the strength of the fiber. Shaping can make the size and performance of the fiber more stable and reduce deformation during use.
