Staple Fiber Needled Geotextile

Staple Fiber Needled Geotextile


Staple fiber needled geotextile is made of polyester or polypropylene staple fiber by needled consolidation, the fibers arranged into a three-dimensional structure, intertwining and interlocking, with good uniform mechanical properties in all directions, while having good vertical and horizontal drainage performance and excellent extension performance and high biological resistance, acid and alkali resistance, aging resistance and other chemical stability. At the same time, it also has a wide aperture range, zigzag pore distribution, excellent permeability and filtration performance.
