What are the production processes of polypropylene industrial silk?

Today, I will give you a brief introduction to the production process of polypropylene industrial silk.

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

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

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

Suining County Tongjia Chemical Fiber Factory was founded in 2013, the main products 300D-3000D color high strength polypropylene yarn, polypropylene double twist, polypropylene industrial silk, polypropylene high-strength silk, etc., the products have high strength, light weight, heat reduction uniform, flame retardant, anti-aging, low thermal conductivity, are widely used in a variety of industrial cloth, cable, container bag, anti-cracking engineering fiber and other products.
