Today, we mainly introduce high-strength polypropylene fiber main production process, and for everyone to answer their technical options on the issue!

With the continuous improvement of the use of high-strength polypropylene fiber, high-strength polypropylene fiber has gradually become a variety of synthetic fiber in a very competitive material, its production equipment investment is low, cheap raw materials, energy consumption, environmental pollution, Of the technical and economic advantages. Widely used in rope, net, belt, cloth, line and other production. Is now widely used!

Production of high-strength polypropylene fiber has two process lines, namely, spinning and stretching in the two equipment on the two-step method and spinning and pull in the same equipment on a continuous one-step method. One-step short-range spinning and FDY production lines, but also horizontal and vertical two processes. In general, in the one-step method, compared with the horizontal vertical with a high spinning and winding speed, the choice of cheaper flat wire grade polypropylene as raw materials and other advantages, while the horizontal general use of fiber grade polypropylene chips As raw materials, the higher the cost. Two-step method has two kinds of horizontal bundling and vertical single-spindle stretching.

One step and two steps have their own strengths. Two-step method is a more mature technology of traditional technology, because of its spindle position, the need for more operators, high production costs, in addition, the tube tube package small, tube consumption is too much, recycling transportation trouble, but the two-step process So that the two processes can achieve the best requirements of the state, in order to obtain continuous high stability of the tow product, especially for ultra-high strength wire production. And one step because of less waste of silk, saving manpower and labor intensity, high production efficiency. Equipment covers an area of ​​small, energy saving and other advantages, and thus in the polypropylene industry silk, mainly polypropylene and strong lines in the production process is widely used, is a promising future.

Tengzhou Chun Chi to remind the above content to share, for everyone in the future production of high-strength polypropylene fiber, as a reference Oh!
