Professional manufacturers analyze the production process of polypropylene industrial yarn!

1. The two-step process route of polypropylene industrial yarn: first produce UDY or POY, and then carry out drawing and finalizing winding. Due to the small investment and low production technology content, there are many small and medium-sized enterprises in China that adopt this process route. However, the technology is relatively backward, the area is large, the intensity of the production cord is low, the product quality is unstable, the consumption is large, and the production cost is high. New projects are no longer advocated and adopted.

2. One-step process route of polypropylene industrial yarn: It adopts one-step process of spinning, drawing, shaping and retraction, and winding. It has advanced technology, short process and small area. The production of silk has high strength and good quality, so it is currently introduced and new The above projects all adopt a one-step process route.

Suining Tongjia Chemical Fiber Factory was founded in 2013. Its main products are 300D-3000D high-strength polypropylene filaments, polypropylene double-twisted yarns, polypropylene industrial yarns, high-strength polypropylene threads, etc.
