Geotextile
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 inta three-dimensional structure The In addition to good mechanical properties, but also has a good vertical and horizontal drainage. At the same time, it also has a wide pore size range, tortuous pore distribution, excellent permeability and filtration performance.
