What are the production processes of high-strength polypropylene industrial yarn?

1, high-strength polypropylene industrial yarn two-step process route: first production of UDY or POY, and then draft shape winding. At present, there are many small and medium-sized enterprises in China using this process route due to small investment, low production technology content, but the technology is relatively backward, covers a large area, low production cord strength, unstable product quality, large consumption, high production cost, the new project is no longer advocated and adopted.

2, high-strength polypropylene industrial yarn one-step process route: the use of spinning, drawing, shaping back, winding one-step process, advanced technology, short process, small footprint production silk of high strength, good quality, so the current introduction and new projects are using one-step process route.
