Filament geotextile

Filament geotextile is directly made by spinning and needling consolidation with polyester method. The product specification is arbitrarily selected from 80-800g/m². It is a geosynthetic material applied in geotechnical engineering and civil engineering. It is made by polyester filament forming and consolidation method, and its fibers are arranged into a three-dimensional structure. In addition to good mechanical properties, but also has good vertical and horizontal drainage performance and good elongation performance and high resistance to biological, acid and alkali, aging and other chemical stability. At the same time, it also has a wide range of pore size, tortuous pore distribution, excellent permeability and filtration performance.
