Ⅰ.Product Introduction
。
Polyester filament spunbonded needle-punched geotextiles is a synthetic material used in the civil engineering. It is made by web formation and consolidation of polyester filament, and its fibers are arranged in a three-dimensional structure. In addition to good mechanical properties, it also has good vertical and horizontal drainage performance and good elongation properties, as well as high chemical stabilization, such as bio-resistance, acid-base resistance and aging resistance, etc. Meanwhile, it also has a wide aperture range, a circuitous pore distribution, excellent permeability and filtration performance.
Ⅱ.Production Function
Reverse-filtration function, drainage function, isolation function, reinforcement function, anti-seepage function.
