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 setting winding. , Due to small investment and low production technology content, there are still many small and medium-sized enterprises in China that use this process route, but the technology is relatively backward, the area is large, the production cord strength is low, the product quality is unstable, and the consumption is large. The production cost is relatively high, and 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. Therefore, 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, and its main products are 300D—3000D high-strength polypropylene filaments of various colors, polypropylene double-twisted yarns, polypropylene industrial yarns, high-strength polypropylene threads, etc.
