Performance Features

Long-fiber geotextiles are directly made by spinning, needle-punching, and bonding polyester fibers. The product specifications range from 80 to 800g/m² for selection. It is a geosynthetic material used in geotechnical and civil engineering, formed through the method of weaving polyester long fibers into a network and bonding them. The fibers are arranged in a three-dimensional structure. In addition to excellent mechanical properties, it boasts good longitudinal and transverse drainage capabilities, excellent extensibility, and high chemical stability against biological, acidic, alkaline, and aging factors. It also features a wide aperture range, tortuous pore distribution, excellent permeability, and filtration properties.

Product Application

Filtering for hydraulic engineering embankments and slopes, isolation and seepage prevention for canals.

Road, railway, and airport runway foundation isolation, anti-filtering, drainage, soil slopes, retaining walls, and road reinforcement and drainage.

Reinforcement and drainage for port engineering's soft soil treatment, beach embankments, harbor wharfs, and breakwaters.

Polyester filament geotextiles have been widely used in infrastructure construction, and are gradually being applied to an even broader range of fields.
