Warp-knitted composite geotextile is a new type of geotextile made of glass fiber (or synthetic fiber) as a reinforcing material and compounded with staple fiber needle-punched nonwoven fabric.
Warp-knitted composite geotextile is different from general woven fabric. Its biggest feature is that the intersection of the warp and weft is not curved, and each is flat. The two are tied tightly with a binding line, which can be more evenly synchronized across the board, withstand external forces, distribute stress, and when the applied external force tears the material instantaneously, the yarn will gather along the initial split and increase the tear strength.
When the warp knitting is compounded, the warp knitting thread is used to repeatedly travel between the warp, weft yarn and the fiber layer of the staple fiber geotextile, so that the three are knitted 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 nonwoven fabric. Therefore, warp-knitted composite geotextile is a kind of reinforcement, isolation and protection, and has a three-dimensional overall normal and level of good water gathering and different water. Because its solid matrix and pores are continuous phases and become porous filtering effect, it is a multifunctional geotechnical composite material. It is a high-level application of geocomposite substrates in the world today.
