 In the geotechnical reinforcement projects of cross-sea Bridges and in the anti-wind and wave fishing nets of deep-sea aquaculture, a kind of fiber material that seems slender but can bear huge tensile force frequently appears - it is polypropylene high strength yarn.Unlike ordinary polypropylene fibers, this type of fiber, crafted through a special process, is made from polypropylene as the raw material. It is produced by optimizing the melt spinning temperature, increasing the stretching ratio, and adding a high-temperature setting step. The breaking strength of its monofilament needs to reach above 6cN/dtex, and the fineness is controlled within the range of 1.5 to 6 denier. It is an industrial-grade fiber specially designed for high-intensity demand scenarios.

Its "mechanical advantages" of tensile resistance and wear resistance have made it a favorite in the engineering field. In the production of geogrids, polypropylene high-strength filaments can withstand a tensile force of several thousand Newtons per square meter. Even if they are buried in the soil for a long time, their strength will not decline due to friction. When used to make industrial conveyor belts, its wear resistance is 2 to 3 times that of ordinary polypropylene, and its service life is significantly extended. What's even more remarkable is that its strength remains almost unchanged in a humid environment, which far exceeds that of traditional polyester high-strength filament. It is particularly suitable for humid scenarios such as water conservancy and Marine areas.

The "dual boost" of lightweight and chemical stability of polypropylene high strength yarn has further expanded its application boundaries. With a low density of 0.91g/cm, the bulletproof vests made of it are 30% lighter than those made of traditional materials, ensuring protective performance while reducing the burden of wearing. It will not corrode or swell when exposed to acid or alkali solutions with a concentration of less than 30%, and thus is often used as the base material for filter cloth in the chemical industry. From the reinforcement and strengthening of highway subgrades to the high-temperature resistant inner layer of fire suits, polypropylene high-strength filament, with its clear product definition and outstanding characteristic advantages, is playing the role of an "invisible supporter" in multiple industrial fields.
