The secret of the production process of PP high-strength yarn!

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

The one-step method has short-course 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 high 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 stretching and vertical single-spindle stretching.

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 more mature traditional technology. Because of its large number of spindles, more operators, and high production costs, in addition, the winding pipe is small, the pipe consumption is too large, 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 super high-strength yarn.

Shanghai Jinci Industrial Co., Ltd. was established in March 2006. It is a large-scale entity company specializing in the production and sales of polypropylene fiber (PP yarn). The company’s products include polypropylene general-strength yarn, PP high-strength yarn, polypropylene anti-aging yarn, polypropylene plus Twisted yarn, polypropylene hollow yarn, polypropylene fluorescent yarn, polypropylene luminous yarn, polypropylene flame-retardant yarn, polypropylene air change yarn, etc.
