Warp Knitted Polyester grid Composite Geotextile

Warp-knitted polyester grid composite geotextile is a new geotechnical material made of polyester fiber (or synthetic fiber) as reinforcing material and compounded with broken needle-punched non-woven geotextile. Warp-knitted polyester grid conforms to geotextile, which is different from general woven fabrics. Its characteristic is that the intersection points of warp and weft are not bent, and each is in a straight state. Bind the two firmly with binding wires, which can synchronize evenly, withstand external forces and distribute stress. When the external force is applied to tear the material, the yarns will gather along the crack to increase the tear resistance. When warp knitting is compounded, the warp knitting binding thread is used to repeatedly pass between the warp, weft yarns and the fiber layers of the short fiber needle punched geotextile, so that the three are integrated into one. Therefore, the warp-knitted composite geotextile not only has the characteristics of high tensile strength and low elongation, but also has the performance of needle-punched fly woven fabric. Therefore, the warp-knitted composite geotextile can be used for reinforcement, isolation and protection. It has a three-dimensional overall normal and horizontal function of better water gathering and water conduction. Because its solid matrix and pores are continuous phases and have a porous filtering effect, it is a multifunctional geocomposite material and is also a high-level base material for geocomposite applications in the world today.

Description of  Warp Knitted Polyester grid Composite Geotextile

Polyester grid composite geotextile is a new composite material used in the construction and renovation of concrete pavements to prevent reflective cracks, water damage and enhance the load-bearing capacity of the pavement. It has the functions of resisting high temperature rutting, resisting fatigue cracking, and delaying reflective cracks, thereby extending the service life of the road surface.

• ◆1.The stabilizing effect of reinforcement: it can transfer or distribute the local stress acting on the soil to a larger area, stably limiting the deformation and settlement of geotechnical engineering during long-term use.
• ◆2.Isolation effect: Geotextiles are used to isolate different geotechnical structural materials to form interfaces, so that they can exert their respective characteristics and overall effects according to design requirements.
• ◆3.Protective effect: Geotextile has good puncture resistance and good protective performance.
• ◆4.Drainage and reverse filtration: Geotextile can allow water to pass through and block the loss of sand particles. Placing the geotextile horizontally in the flowing liquid channel with suspended particles has the function of blocking fine mud particles and allowing liquid to pass through.
