Utilizing warp-knitted directional structure, the warp and weft yarns in the fabric are in a straight, non-bent state, with high-strength fiber filaments bound together at the crossover points to form sturdy bonding points, fully leveraging their mechanical properties. The high-strength polyester warp-knitted geogrid boasts high tensile strength, low elongation, and strong tear resistance.Low difference in longitudinal and transverse strength, resistant to UV aging, wear, corrosion, lightweight, and with strong interlocking force with soil or gravel. It significantly enhances the shear resistance and reinforcing of soil, improving its overall integrity and load-bearing capacity. Made by welding the junction points using a special reinforced bonding technique, the geogrid is formed from a single strip, which is woven or laminated with a certain spacing. The polymer mesh material, formed by stretching, can be either unidirectional or bidirectional, depending on the stretching direction during manufacturing.It is punched on polymer plate (mainly made of polypropylene or high-density polypropylene) extruded under pressure, and then stretched in a directional manner under heating conditions. Unidirectional stretched mesh is made by stretching only along the length of the plate; bidirectional stretched mesh is produced by further stretching the unidirectional mesh perpendicular to its length. The polyester fiber woven geotextile selects high-strength polyester fiber as raw material. As the polymer高分子 in the plastic geotextile rearranges and orients itself during the heating and extension process, the bonding force between molecular chains is strengthened, achieving the purpose of enhancing its strength. Its elongation rate is only 10% to 15% of the original plate. If carbon black or other anti-aging materials are added to the geotextile,It can be made to possess excellent durability, including resistance to acids, alkalis, corrosion, and aging. The steel-plastic geogrid, composed of high-tensile steel wire (or other fibers), treated specially, and blended with polyethylene (PE), along with other additives, is extruded to form a composite high-tensile tensile band, featuring a rough embossed surface, is known as a high-tensile reinforced geotextile tape.
