Polypropylene FDY yarn is an important polypropylene fiber product.
The production process of Polypropylene FDY yarn mainly includes several important steps such as raw material processing, polymerization, spinning, stretching and weaving. Among them, stretching is a key step. Through stretching, the molecular structure of the fibers becomes more regular, thereby enhancing the strength of the fibers.
What are the characteristics of Polypropylene FDY yarn?
High strength: After undergoing full stretching process treatment, the molecular structure is arranged more regularly and closely, endowing it with high strength. Compared with ordinary polypropylene filament, it can better withstand tensile force and can be used in fields with high strength requirements, such as industrial ropes, safety belts, geotextiles, etc.
Uv resistance: Polypropylene FDY yarn has excellent UV resistance and is not prone to aging due to prolonged exposure to sunlight.
Acid and alkali resistance: It has good corrosion resistance to acids, alkalis and other chemical substances, and is suitable for various chemical environments.
Lightweight: It has a low density and is light in weight, making it convenient to carry and transport.
Wear-resistant: The surface is smooth, with good wear resistance and is not prone to wear.
Low thermal conductivity: It has a low thermal conductivity coefficient and certain heat preservation performance.
Seawater corrosion resistance: It can maintain good stability in seawater environments and is not easily corroded.
Environmental protection: Pollution-free, non-toxic, recyclable and granulated, meeting environmental protection requirements.
