Light Weight Good Drainage Material Lightweight Warp Knitted Polyester Geogrid
Production Introduction
Warp knitted polyester geoglage is a kind of grid structure material made of high strength polyester industrial filament by warp knitted directional weaving technology. Its production process includes raw material selection, weaving, coating and inspection steps. Specifically, the geoglage uses high-strength polyester filament without twist as raw material, and uses warp knitting interlining and weft interlining technology to produce, so that the warp and weft yarns are bound together at the crossing point through the high-strength fiber filament to form a firm binding point, so as to give full play to its mechanical properties.
Production Property
Warp knitted dacron gegrates have many advantages, such as high tensile strength, small elongation, high tear strength, ultraviolet aging resistance, wear resistance and corrosion resistance.
Production Application
These characteristics make it widely used in soft soil foundation treatment, roadbed reinforcement, embankment reinforcement and water conservancy projects to improve project quality and reduce project cost.
