[0002] Polyethylene fiber is a synthetic fiber made of polyethylene. It is lightweight, wear-resistant, corrosion-resistant, not easy to deform, and not easy to absorb water. Polyethylene fiber can be used to make ropes, fabrics, filter materials, industrial supplies, etc. It has good wear resistance and weather resistance and is widely used in various fields. Polyethylene fiber can also be blended with other fibers to enhance its performance. For example, blending with polyester fiber can improve strength and wear resistance. Because polyethylene fiber has good physical and chemical properties, it is widely used in textiles, industry, construction and other fields.

[0003] In the production process of polyethylene fiber, polyethylene particles need to be added to the extruder, and the particles are melted into a melt by heating and pressure.
