The production process and characteristics of polypropylene polypropylene wire!
1. Process flow
The production process of polypropylene general strong yarn is similar to that of polypropylene high strength yarn, which also requires several process links such as raw material pretreatment, melting rotation, cooling lubrication, drawing and shaping. However, compared with polypropylene high-strength yarn, the production process of polypropylene general filament is simpler, and the corresponding production cost is lower.
2. Features and uses
The strength, elongation and other physical properties of polypropylene general filament are lower than that of polypropylene high strength filament, but its price is more affordable, so it is widely used in low-end textiles and daily necessities, such as clothing, shoes and hats, ropes, crown rope, seat belts and other fields.
