Non Woven Geotextile Fabric
High Strength & Durability: Needle-punched for puncture resistance (roadbeds, slopes).
Superior Filtration & Drainage: Porous structure prevents soil erosion (landfills, walls).
Chemical & UV Resistant: UV-stabilized, anti-corrosion (mining, coastal).
Flexible & Crack-Resistant: Adapts to ground movement (embankments, rail tracks).
Long Lifespan (>50 yrs): Resists aging, extreme temps (–40°C to 120°C).
Product Introduction
Non Woven Geotextile Fabric is produced through the polyester method, involving the direct spinning and needling consolidation of polyester fibers. It is created by forming a three-dimensional structure through the arrangement of polyester long filaments into a net and consolidating them. In addition to exhibiting excellent mechanical properties, it also demonstrates good vertical and horizontal drainage performance, superior extensibility, and high resistance to biological organisms, acids, alkalis, aging, and other chemical stability factors. Simultaneously, it features a wide range of pore sizes, intricate pore distribution, excellent permeability, and filtration performance. Long filament geotextile fabric has found widespread applications in the field of infrastructure construction.

Product Features
1), High-Temperature Resistance: Withstands temperatures up to 230°C, maintaining structural integrity and original physical properties even under high temperatures.
2), Permeability and Planar Drainage: The geotextile fabric, being thick and needle-punched, demonstrates excellent planar drainage and vertical permeability, maintaining these properties even after many years.
3), Creep Resistance: Long filament geotextile fabric has superior resistance to creep compared to other geotextiles, ensuring long-term effectiveness. It withstands erosion by common chemicals in the soil and is resistant to corrosive substances such as gasoline and diesel.
4), Elongation: The fabric has good elongation at a certain stress level, allowing it to adapt to irregular surfaces with uneven terrain.
