Polyester filament geotextile is made directly by spinning and needle-punching consolidation using polyester method. The product specification is arbitrarily selected from 80-800g / m 2. It is a geosynthetic material used in geotechnical engineering and civil engineering It is made by the method of netting and consolidation of polyester filament, and its fibers are arranged into a three-dimensional structure.
In addition to good mechanical properties, it also has good vertical and horizontal drainage performance, good extension performance and high chemical resistance such as biological resistance, acid and alkali resistance, and aging resistance. At the same time, it also has a wide pore size range, tortuous pore distribution, excellent permeability and filtration performance. Polyester filament geotextile has been widely used in the field of infrastructure construction, and gradually been applied to a wider range of fields.
