Details
Performance characteristics of polyester filament geotextile:
Polyester filament geotextile is made directly from polyester chips through spinning and needle punching consolidation. The product specifications can be selected from 80-800g/m2. It is a geosynthetic material used in geotechnical engineering and civil engineering. Its fibers are arranged in a three-dimensional structure. In addition to having good mechanical properties, it also has good longitudinal and transverse drainage performance and good elongation performance. It has high resistance to biological, acid and alkali, aging and other properties. At the same time, it also has a wide pore size range, tortuous pore distribution, excellent permeability and filtration performance.
Polyester filament geotextile uses:
◎Water conservancy project dam and slope protection anti-filtration, channel isolation, anti-seepage;
◎Highway, railway, airport runway foundation isolation, anti-filtration, drainage, earth slope, retaining wall and road reinforcement, drainage;
◎Port engineering soft foundation treatment, beach embankment, seaport terminal and breakwater reinforcement, drainage;
◎Polyester filament geotextile has been widely used in the field of infrastructure construction and is gradually being used in a wider range of fields.
