[Heping Chemical Fiber] What are the two production processes of polypropylene industrial filament?


There are two production processes for polypropylene industrial silk, two - step process and one - step process.


1. Two-step process route for POLYPROPYLENE industrial silk: UDY or POY is produced first, and then draft and finalize the winding. Due to small investment and low production technology content, there are still many small and medium-sized enterprises in China adopting this process route at present, but the technology is relatively backward, covers a large area, the production cord strength is low, the product quality is unstable, the consumption is large, the production cost is high, the new project is no longer advocated and adopted.


2. One-step process of POLYPROPYLENE industrial silk: one-step process of spinning, drafting, shaping, retracting and winding is adopted. With advanced technology, short flow, high strength and good quality of the production silk covering a small area, one-step process is adopted in both the introduced projects and the new projects.
