With continuous development, polypropylene high-strength yarn has gradually become a very competitive chemical fiber product among a variety of synthetic fibers. It has low investment in production equipment, cheap raw materials, ultra-low energy consumption, less environmental pollution, and has obvious advantages. Technical and economic advantages. In addition, polypropylene high-strength yarns are widely used in the production of ropes, nets, belts, cloths, threads, etc., and are now widely used!

What is the main production process of polypropylene high-strength yarn?

There are two main process routes for producing polypropylene high-strength yarn, namely spinning and drawing, a two-step method carried out on two equipment. And the one-step method in which spinning and drawing are carried out continuously on the same equipment. 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.

The one-step and two-step methods of polypropylene high-strength yarn have their own advantages. 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 achieve particularly good requirements, so as to obtain the continuous and stable high quality of tow products, which is especially suitable for the production of ultra-high polypropylene high-strength yarns. The one-step method saves manpower and labor intensity due to less waste silk, and has high production efficiency. The equipment has the advantages of small area and energy saving. Therefore, it is widely used in the production of polypropylene industrial yarns, mainly polypropylene normal-strength yarns and medium-strength yarns. It is a promising advanced technology.

The above is the sharing of the main production technology of polypropylene high-strength yarn, I hope it can be helpful to everyone!
