Polyester filament geotextile is made by polyester textile needle consolidation , product specifications from 80-800g/m2 , it is geosynthetic application in geotechnical and civil engineering , they are arranged in three-dimensional structure of the fiber . In addition to having good mechanical properties, but also has a good aspect to the drainage performance and good elongation properties and high resistance to biological , acid , anti-aging chemical stability . Meanwhile , it also has a wide range of pore size , pore distribution tortuous , excellent permeability and filtration performance .
Advantage
1. Excellent drainage performance
2 .High strength,excellent tenacity
3. Anti-aging,anti-acid and alkali
4. Can accommodate irregular deformations
5. Creep, corrosion and abrasion resistance
6. Safe and easy for construction
