Polypropylene high strength yarn, as an important category of the polypropylene fiber family, is made from polypropylene as the core raw material. It is produced through the modified melt spinning process and then undergoes high-temperature stretching and shaping. With its regular molecular structure and high crystallinity, it has become a commonly used material in industrial textiles. The tensile strength of its single filament can reach 6-9 cN/dtex, the single filament fineness is concentrated between 1.5 and 6 deniers, the tensile elongation rate is stable at 15%-30%, and it is extremely sensitive to humidity, maintaining a stable shape in complex environments.
In the field of geosynthetics, polypropylene high strength yarns are the core raw material for geogrids and geotextiles, and are widely used in various engineering projects such as water conservancy, roads, and construction. In the construction of water conservancy dams, it acts as an enhanced framework, effectively enhancing the tensile strength of geotextiles and preventing soil erosion; in the reinforcement of road subgrades, it can suppress reflective cracks, extend the service life of the roads, and at the same time, its permeable and filtering properties can achieve the dual effects of drainage and sand prevention.
In the field of safety protection, polypropylene high-strength fibers, due to their excellent mechanical properties, are used to manufacture products such as car seat belts and lifting belts. Their stable strength and toughness can effectively protect personnel and equipment during force application. In marine engineering, they can be made into high-strength fishing nets and mooring ropes. After seawater aging, their strength retention rate is relatively high, and their lightweight characteristic makes them convenient for transportation and laying. In addition, they are also used in industrial filter materials and carpet base fabrics, thanks to their characteristics of chemical corrosion resistance and low moisture absorption, which can enhance the product's service life and user experience.
