The lawn is made of polyethylene material. Fiber degree 8800D. Mainly applicable to sports venues.

Artificial turf is composed of 3 layers of material. The base layer is composed of compacted soil, gravel and asphalt or concrete layer. The base layer for solid, deformation, surface smooth and impervious, namely the general concrete ground. The hockey field area is large, construction must handle good foundation layer, prevent subsidence. If spread layer of concrete, concrete curing after cutting out the expansion joint, preventing the deformation of thermal expansion and fracture. Top of the base layer is a layer of buffer layer, usually rubber or foam. Rubber elastic medium, the thickness of 3 ~ 5mm. Foam of low cost, but poor elasticity, thickness of 5 ~ 10mm, thick grass too soft, and depression; thin short of elasticity, no buffer action. The buffer layer to be firmly stuck on the base layer, usually with white latex or all-purpose adhesive paste. The third layer, and surface, as the turf layer. Manufacturing of surface shape of a villous turf, annular curling shape nylon filament, polypropylene fiber, leafy turf turf nylon wire of permeable turf. This layer has to be used in rubber or foam latex adhesive. Construction must be fully gelatinize, followed by pressing stuck, unable to fold. In foreign countries, the turf layer common two: 1, the turf layer frond fiber is thin, only 1.2 ~ 1.5mm; 2, turf fibers thicker, 20 ~ 24mm, the quartz filled almost to the top of the fiber.
