Demystify! Two production processes of PP high-strength yarn!

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

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

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

The one-step method and the two-step method have their own strengths. The two-step method is a relatively mature traditional technology. Because of its large number of spindles, more operators, and high production costs, in addition, the hauling pipe is small in package, the pipe consumption is too much, and the recycling and transportation is troublesome. However, the two-step process The two-stage processing process can reach the super-required state, so as to obtain the continuous and stable high quality of the tow product, which is especially suitable for the production of ultra-high-strength silk.
