Polypropylene yarn raw materials; introduction to the formation of polypropylene, let us start from its advantages.

The advantage of the polypropylene yarn is that the texture is light, and its density is only 0.91 g / cm3 is a common variety of density in chemical fibers, so the same weight of polypropylene can be higher than the higher coverage area obtained by other fibers. The strength of strong polypropylene is high, the strength is large, the initial modulus is high, and the elasticity is excellent. Therefore, the polypropylene wear resistance; in addition, the moisture of polypropylene is substantially equal to the strength, so it is an ideal material for making fishing nets, cables; moisture absorption and dyeing properties are well warm; almost unhappy, but the core suction ability is very strong. The moisture absorption is obvious; the hygroscopicity of polypropylene is small, almost unhelax, and the retort ratio under normal atmosphere is close to zero. In addition, polypropylene insulation is good, but static electricity is easily generated. Due to the smaller thermal conductivity of polypropylene, the strength is good; the strength of high polypropylene elastic wire is second only to nylon, but the price is only a nylon 1/3; the size of the fabric is stable, the wear-resistant elasticity is good, chemical stability is good.
