PET continuous filament nonwoven · 100-800 g/m²
Filament Geotextile: Filament geotextile (GB/T 17639) is a continuous-filament PET nonwoven with higher strength, puncture resistance and durability than staple geotextile at the same weight. Typical uses: filtration and separation in waterworks, subgrade reinforcement, slope protection, and protection layers above/below geomembranes in landfills. Common weights are 200-600 g/m², width 1-6m.

Filament geotextile is made of continuous polyester filaments by spunbond needle-punching. At equal weight it outperforms staple fabric in tensile and burst strength, aging and creep resistance — ideal for filtration, reinforcement and membrane protection. Produced to GB/T 17639.
| Item | Specification |
|---|---|
| Weight | 100-800 g/m² |
| Width | 1m-6m |
| Tensile strength | 200g/m² ≥ approx. 9.5 kN/m MD, increases with weight |
| Elongation | 25%-100% |
| CBR burst | 300g/m² ≥ approx. 1.5 kN |
| AOS (O90) | 0.07-0.2mm typical |
| Standard | GB/T 17639 |
| Type | Features | Application | Typical works |
|---|---|---|---|
| Filtration type | Small AOS, high permittivity | Filter & separation | River banks, drainage ditches |
| Reinforcement type | High strength, low elongation | Subgrade reinforcement | Roads, railways, soft ground |
| Protection type | Thick, high burst | Membrane cushion | Landfills, reservoirs |
| Drainage companion | Used with drainage net | Leachate conduction | Landfills, tunnels |
| Common problem | Yurun Geosynthetics solution |
|---|---|
| Cushion punctured by stones | Higher burst strength than staple at equal weight |
| Filter clogging | Matched AOS: retains soil, passes water |
| Subgrade cracking | Reinforcement spreads loads |
| Long-term exposure aging | Better creep & UV resistance for exposed zones |

Dezhou Yurun Geosynthetics Co., Ltd. is a source manufacturer with its own geomembrane and geotextile production lines — not a trading company. Filament Geotextile is produced and inspected to current national standards with third-party batch test reports. Common specifications are kept in stock, and cut-to-size production is available against your layout drawing. Nationwide supply and export, with free selection advice and welding guidance.
Filament (continuous fibers) is stronger and more durable; staple (short fibers) is more economical. Use filament for protection layers, exposed or reinforced zones; staple for general filtration and separation.
300 g/m² for general works; 400-600 g/m² for landfills and stony subgrades.
≥200mm on land, ≥300mm underwater or in critical filters, lapped with the flow.
