With the development of the market, great changes have taken place in artificial grass in terms of materials, technology, construction, etc. These changes have made artificial grass closer to natural grass in terms of sports performance. It can be divided into 6 stages: the first stage is mainly made of nylon material, which looks like a carpet, has poor elasticity, has no protection for athletes, and is easy to be injured; the second stage is mainly made of PP material, which is filled with quartz sand particles and has high hardness; The third stage is mainly PE material, filled with quartz sand and rubber particles, which has the elasticity of natural grass and greatly improved sports performance. The fourth stage is based on FIFA certification, focusing on system engineering such as foundation and construction. In this stage of construction, in addition to the mesh products, there are also products such as straight-curved blends. The materials are PE and PP blends, PE and nylon blends, and the sports performance is further strengthened. The fifth stage is mainly monofilament grass. In addition, it also pursues a more ideal appearance and pays more attention to the construction of the system; the sixth stage is mainly curly grass, an artificial grass specially developed for gate courts and golf.
