Non Woven Needle Punched Geotextile
The polyester filament geotextile is made directly by the polyester method through the spinning of the needle. The product specification is selected from 80-800g/m 2. Non Woven Needle Punched Geotextile is a kind of geosynthetics used in geotechnical engineering and civil engineering. It is made of polyester filament wire forming and consolidation, and its fiber is arranged into three dimensional structure. In addition to good mechanical properties, it has good vertical and horizontal drainage performance and good extension performance and high chemical stability, such as biological, acid and alkali resistance, aging resistance and so on. At the same time, Non Woven Needle Punched Geotextile has wider pore size, tortuous pore distribution, excellent permeability and filtration performance.
