What are the production processes of polypropylene industrial yarn?

1. Two-step process route of polypropylene industrial yarn: first produce UDY or POY, and then carry out drafting and winding. Due to the small investment and low production technology content, there are still many small and medium-sized enterprises in China that use this process route. However, the technology is backward, the area is large, the strength of the production cord is low, the product quality is unstable, the consumption is large, and the production cost is high. The new project has no longer advocated and adopted.

2. One-step process route of polypropylene industrial yarn: one-step process of spinning, drafting, shape retraction and winding, advanced technology, short process, small footprint, high production strength and good quality, so it is currently introduced and new The above projects all use a one-step process route.
