Nonwoven geotextile filter fabric made from polypropylene come in ounces per square yard. Used for drainage, soil separation, and reinforcement.
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.
PP /PET filament needle punched non-woven geotextile, it is geotechnical engineering and civil engineering applications in a geosynthetics, is through the polypropylene / polyester filament into a network and consolidation method, the fiber arranged into a three-dimensional structure The In addition to good mechanical properties, but also has a good vertical and horizontal drainage performance and good extension properties and high resistance to biological, acid and alkali, anti-aging and other chemical stability. At the same time, it also has a wide pore size range, tortuous pore distribution, excellent permeability and filtration performance.

Features of Nonwoven Geotextile Filter Fabric
1. Good Flexibility: flexible in structures preventing block drainage holes.
2. Resistant to corrosion, acids and alkalis, anti-age.
3. Good performance in filtration under high pressure of soil.
4. Environment friendly and easy construction.
Application of Nonwoven Geotextile Filter Fabric
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.
* Filtration or separation layers in civil engineering projects of roads and railway construction.
* Protect layer for geomembranes in landfill construction.
* Coastal defence applications.
* Landscaping projects to maintain soil and protect land surfaces and structures from weeds and root growth.
