Polyester Filament Needle Punched Geotextile sed to separate, filter,reinforce, protect or drain. Geotextiles are commenly used to separate layers like clay and drainage and to protect liner from damage.
Polyester Filament Needle Punched Geotextile was made from virgin polyester chips, the continous filament was extruded from polyester chip by machine directly by spunbond process. Pet Long Fiber Nonwoven Geotextile punch together to get the stable 3D with highter strength fabric. so Nonwoven Geotextile Fiber has high strength, good creep property excellent and erosion resistance, aging-resistance and heat resistance.

Product Property
1) Anti-aging, the product has very high anti-ultraviolet radiation ability, not easy to degradation.
2) High temperature resistance to up to 230℃ maintaining structure stability and original physical properties.
3) High flat drainage and vertical permeability.
4) High creep resistance.
5) Resistance of erosion of chemicals in soil as well as the corrosion of gasoline and diesel etc.
6) High elongation under certain stress, thus able to adapt to uneven and irregular bases.
Application
Polyester Filament Needle Punched Geotextile is mainly used in the following projects: in the highway (including temporary road) railway, embankment, earth rock dam, airport, sports field and other projects, to strengthen the weak foundation at the same time play the role of isolation and filtration.
Railway engineering, water conservancy engineering, landfill, bank slope protection, horticulture engineering, agricultural engineering, sports venues.
Separation and reinforcement in road and railway construction.
Prevention of soil movement in erosion control measures.
