Long Filament Geotextile is a high-performance polyester geosynthetic material classified as premium Non-woven Fabric, widely used in tunnel, landfill, water conservancy and road reinforcement projects with five core competitive strengths.
It features even and continuous fiber structure formed by needle punching and thermal bonding of polyester long filaments. The long molecular chains remain intact without broken short fiber residues, with evenly distributed fibers to deliver consistent mechanical performance across the whole roll. It owns superior physical and mechanical properties compared with staple fiber geotextiles. Under the same unit weight, its breaking strength reaches 1.5 to 2 times that of short fiber products, with stronger bursting and tearing resistance to bear heavy soil loads and external pulling force for large-scale engineering. Its pore structure can be precisely adjusted by tuning needle punching density and hot pressing temperature, balancing water permeabilit…
