Tongjia sells all kinds of high-quality polypropylene high-strength yarn!

1. One-step production process of polypropylene high-strength yarn

The one-step method includes short-run spinning and FDY production lines, and is divided into two processes: horizontal and vertical. Generally speaking, in the one-step method, compared with the horizontal type, the vertical type has the advantages of high spinning and winding speed, and cheaper flat-filament polypropylene can be used as raw materials, while the horizontal type generally uses fiber-grade polypropylene chips. As raw materials, the cost is high. There are two types of two-step method: horizontal cluster drawing and vertical single-spindle drawing.

2. Two-step production process of polypropylene high-strength yarn

The one-step method and the two-step method have their own advantages. The two-step method is a traditional process with relatively mature technology. Because of its large number of ingots, many operators are required, and the production cost is high. In addition, the coiled tube is small, the tube consumption is too high, and the recycling and transportation are troublesome. However, the two-step process It can make the two stages of processing can reach the super good state, so as to obtain the continuous and stable high quality of tow products, especially suitable for the production of ultra-high-strength yarns.

Suining Tongjia Chemical Fiber Factory was founded in 2013. The main products are 300D-3000D high-strength polypropylene filament, polypropylene double-twisted yarn, polypropylene industrial yarn, high-strength polypropylene yarn, etc.
