Today, I will give you a brief introduction to the production process of polypropylene industrial yarn?
There are two production processes for polypropylene industrial yarn, which are a two-step process and a one-step process.
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.
