High strength PP double twist yarn of the two production process!

1, high strength PP double twist yarnone step production process

One - step method has short spinning and FDY production line, and divided into horizontal and vertical two processes. Generally speaking, in one step method, compared with horizontal type, vertical has the advantages of high spinning and winding speed, can choose cheaper flat filament grade polypropylene as raw material, and horizontal type generally uses fiber grade polypropylene slice as raw material, the cost is higher. The two - step method has two kinds: horizontal cluster drawing and vertical single ingot drawing.

2, high strength PP double twist yarn two-step production process

The one-step method and the two-step method each have their advantages. The two-step process is a more mature traditional technology, because of its ingot position, the need for operators, high production cost, in addition, the coiled tube is small, tube consumption is too much, recovery and transportation trouble, but the two-step process can make the two stages of processing can reach the super good requirements of the state, in order to obtain the sustainable and stable high quality of the tow products, especially suitable for the production of ultra-high strength silk.

Suining County Tongjia Chemical Fiber Factory was built in 2013, the main products 300D-3000D assorted high-strength polypropylene filament, polypropylene double twist silk, polypropylene industrial silk, high-strength polypropylene wire, etc., the products have high strength, light weight, heat reduction uniform, flame retardant, anti-aging, low thermal conductivity, are widely used in a variety of industrial cloth, rope, container bag, crack resistant engineering fiber and other products.
