Polyester needle-punched non-woven geotextiles are carded, finely ground, needle-punched and wound into rolls to make finished products. Because polypropylene has good air and water permeability, it can retain sand and soil when flowing. Polypropylene short fibers have good hydraulic conductivity and can form drainage channels inside the soil, thereby expelling excess air or water from the soil structure.
characteristic:
The aperture is not easy to be blocked, high permeability, corrosion resistance, acid and alkali resistance, insect resistance, oxidation resistance, good flexibility, and easy construction.
usage:
Used in hydroelectric power generation, highways, railways, ports, airports, sports buildings, tunnels, coastal beaches and other fields, for filtration, separation, drainage and protection.
