Polypropylene (PP Polypropylene) is a rising star of synthetic fibers, the scientific name of polypropylene fibers. High-strength polypropylene fiber production process is simple, "one step spinning" "two-step spinning." By propylene as raw materials by polymerization and modification of its raw materials, melt spinning, spinning melt filtration, blowing cooling, winding, fiber system. Compared with the production process of "one-step spinning" and "two-step spinning", it has the characteristics of small occupation area, less personnel and low cost, and the problem is that the strength of the high-strength filament of the "one-step spinning" process is low. The invention is characterized in that polypropylene resin whose melt flow index MFI is 5-40 and whose molecular weight distribution index MWD is less than 7 is 400 to 1600 / min, which is characterized in that the method comprises the following steps: Speed ​​spun-forming, and then in the spindle traction twisting machine for two-stage traction and twisting, the system made of multi-filament 400-1600 dtex of high-strength polypropylene filament.

Flame near the top of the yellow, blue bottom, emitting a taste of oil, burned ashes for the hard round light brown particles, hand twist fragile. As the production process is simple, inexpensive products, high strength, the relative density of light and so on. Is now the fourth largest synthetic fiber varieties, common chemical fiber is the lightest fiber. But poor thermal stability, intolerance of the sun, easy to aging fragile damage, this often joined in the polypropylene anti-aging agent.
Polypropylene high strength wire Uses: It can be used to knit various kinds of knitwear, such as knitting socks, gloves, sweaters, knitted pants, dish cloth, mosquito nets cloth, floc, warm packing and diaper. Carpets, fishing nets, canvas, hose, reinforced concrete and so on.
