Long-filament geotextile


Long-fiber geotextiles are nonwoven geosynthetic materials made from polyester (PET) or polypropylene (PP) long fibers, produced via needle-punching or thermal bonding processes. They feature high strength, corrosion resistance, and excellent water permeability and filtration capabilities, making them widely used in engineering applications such as roadways, railways, and water conservancy projects for separation, filtration, protection, and drainage purposes.
