Filament Nonwoven Geotextile
Filament spunbond needle-punched nonwoven geotextile, a high-performance permeable filtration geosynthetic material. Compared to staple fiber products, filament geotextiles have higher strength, more uniform structure, and superior durability.
Filament spunbond needle-punched nonwoven geotextiles are high-strength nonwoven geotextiles, made from PET or PP through high-temperature melt extrusion and needle-punching bonding processes. Compared to short-fiber products, long-filament geotextiles have higher strength, more uniform structure, and superior durability. Our products can be manufactured according to GB/T, ASTM, ISO, and other standards, and all raw materials are pure new resin.
Production Process: High-strength filament nonwoven geotextile is produced through high-temperature melt extrusion, spinning into a web, web laying, and needle punching consolidation processes.
Quality Control: The entire production process is monitored by automation. Strict factory inspections are conducted in accordance with standards, to ensure that the dimensions, appearance, and key properties.
After-sales Service: We have over one million square meters of construction experience, and our team can provide on-site construction services. We also offer remote technical guidance to assist with welding and construction.
Advantages
- High strength and low creep
- Excellent burst and tear resistance
- Good resistance to dynamic perforation
- PET filaments have excellent UV resistance

- High-grade highways and airport runways:
- Reinforced subbase layers in soft soil treatment, and anti-reflective cracking layers at the bottom of semi-rigid base courses.
- Railway ballasted and ballastless track:
- Laid between the ballast layer and the subgrade, serving as isolation, reinforcement, and drainage, preventing ballast from embedding into the subgrade soil. Recommended nominal strength specifications are 30kN/m to 48kN/m.
- Tailyards and heap leaching ponds:
- As the upper protective layer of HDPE geomembrane, it withstands the load and compaction of hundreds of millimeters of graded ore. The long-filament structure ensures no creep or cracking under long-term loads.
- Land reclamation and hydraulic reclamation projects:
- Laid on the surface of extremely soft soil foundations, forming a stable construction platform and accelerating drainage and consolidation. The high strength and biodegradability of long-filament geotextiles make them perform excellently in marine environments.
- Hazardous waste disposal site lining system:
- PP filament geotextile is widely used as an impermeable protective layer in hazardous waste landfills due to its excellent acid and alkali resistance.
