High strength polypropylene network wire is mainly polypropylene as the core raw material, specifically, this polypropylene needs to have specific quality characteristics. Usually selected after strict screening, high-purity polypropylene resin, the melt flow rate is precisely regulated in the appropriate range, generally 2 to 15g/10min, this range can ensure that in the complex spinning process, polypropylene shows excellent fluidity, just like a smart stream smoothly through the precision channel of spinning equipment, for the smooth spinning foundation. Not only that, the isotropy requirements of polypropylene resin are extremely strict, up to 95% or more, a high degree of isotropy promotes the formation of a regular and orderly crystalline structure inside the fiber, giving the fiber excellent crystallinity and strong strength, which has become the key internal factor supporting the high performance of high strength polypropylene fiber network wire.
High purity polypropylene resin: This is the main raw material of high strength polypropylene network yarn. Generally, polypropylene resin with moderate melt flow rate (MFR) is selected, and MFR is usually between 2-15g /10min to ensure good fluidity and spinnability in the spinning process. At the same time, the isotropy of the polypropylene resin is required to be high, generally above 95%, to ensure that the fiber has a high crystallinity and strength.
Additives: In order to improve the performance of high-strength polypropylene network wire, some auxiliary additives are also added. For example, the addition of antioxidants can prevent the oxidative degradation of polypropylene during processing and use, improve the thermal stability and aging resistance of the fiber; The addition of ultraviolet absorbent can enhance the absorption capacity of the fiber to ultraviolet light, improve the light resistance of the fiber, and prevent the fiber from reducing its strength due to ultraviolet radiation when used outdoors; The addition of nucleating agent can change the crystalline form and size of polypropylene, improve the crystallization speed and crystallinity of the fiber, and thus improve the strength and rigidity of the fiber.
