Polypropylene high strength yarn is a kind of synthetic fiber made from polypropylene. It has outstanding physical properties and is widely used in many industrial fields. This fiber features high strength, with a breaking strength of 6-8 CN /dtex or even higher. This indicator is close to the level of some polyester and nylon industrial filaments, making it suitable for high-load scenarios. Meanwhile, its dry strength is basically the same as its wet strength because the strength of the fiber remains consistent under standard and wet conditions, which is attributed to its almost zero hygroscopicity. This characteristic also makes polypropylene high-strength filament particularly suitable for Marine environments or situations where moisture absorption needs to be avoided.

In terms of density, polypropylene high-strength filament shows a significant advantage. Its density is only 0.91g/cm, making it the lightest among common chemical fibers, even lighter than polyester and nylon. This feature enables the final product to be lighter in weight, which is particularly valued in application fields that require lightweighting.

Polypropylene high strength yarn has good wear resistance and flexibility. Its wear resistance is basically the same in both dry and wet states, and its resistance to flat abrasion is close to that of nylon. Although its resistance to bending and abrasion is slightly inferior, it still shows good durability. In addition, the fiber has a relatively high resilience rate, reaching over 90% when elongated by 3%, which indicates that it has excellent elastic recovery ability.

Chemical resistance is another prominent feature of polypropylene high-strength filament. Due to the lack of active groups in the molecular structure of polypropylene, it has excellent stability against acids, bases and other chemicals, and its performance is superior to that of fibers such as polyester and nylon. This feature enables it to be reliably used in fields such as chemical engineering and environmental protection where corrosive environments exist.

However, polypropylene high-strength filament also has some performance limitations. Its heat resistance is relatively poor, with a melting point of approximately 176℃. Use with caution in high-temperature environments. In addition, it has poor light resistance and is prone to aging when directly exposed to sunlight. However, by adding light stabilizers and anti-aging agents, its UV resistance can be significantly improved, making it meet the requirements for outdoor use.

The production process of high-strength polypropylene filament is also constantly improving. Through special techniques such as high-fold stretching and online network node formation, high-strength polypropylene network filament can be produced. This type of fiber has better bundling properties and mechanical performance, facilitating subsequent processing. Its application scope has been further expanded to geogrids, safety protection products, medical and environmental protection fields, etc.

In conclusion, polypropylene high-strength filament, with its physical properties such as high strength, light weight, chemical corrosion resistance and good wear resistance, has become a competitive industrial fiber material. Through continuous process improvement and modification treatment, its performance is being further optimized, and its application prospects are very broad.
