PP high-strength yarn production process and characteristics!

1. Process flow

The production process of high strength polypropylene fiber mainly includes: raw material pretreatment, melting rotation, cooling lubrication, tensile shaping and other links. Among them, the raw material pretreatment is to improve the quality of the fiber, remove the impurities in the textile raw materials, and ensure the color and color of the fiber

The gloss increases strength and elongation at the same time. The melting rotation link is used to heat and melt the pre-treated raw materials, so that the fibers become liquid state, and the fibers are uniformly cooled and solidified to form filament strips by rotating carding and other ways. The cooling and lubrication link is sprayed

The process of water cooling and oil lubrication makes the surface of the wire strip evenly lubricated, reduces the surface tension of the wire strip and reduces the breakage rate. Finally, the fibers are stretched and shaped to form a certain strength and fineness.

2. Features and uses

PP high-strength yarn  has high strength and elongation, ultraviolet resistance, high temperature resistance, corrosion resistance, not easy to fade and other characteristics, widely used in industrial, medical, sporting goods and other fields.
