Warp-knitted polyester geogrid select pet polyester fiber as raw material. Use directional warp, weft of the fabric and yarn mutual bent State, crossing with high-strength fiber filament bundles combine to form a strong point, bring into full play their mechanical properties, warp-knitted polyester geogrid with high tensile strength, elongation strength is small, anti stress intensity big, small differences in the vertical and horizontal strength, UV-resistant, wear resistance, corrosion resistance, light weight, and soil or aggregate interlock on enhanced soil reinforcement on shear and enhance the integrity of the soil and the load, has a significant role.
