Artificial turf is made by sewing PA, PP, PE grass filaments and PP mesh cloth together through a grass weaving machine, and then using butyl rubber to compound the two together. Or you can understand it this way, artificial turf is a chemical product with natural grass sports performance that has synthetic fibers imitating grass blades implanted in a woven base fabric and coated on the back with a coating that acts as a fixation.

The composite layer is composed of a rubber particle layer, a super absorbent resin layer, and a waterproof coating layer. The rubber particle layer can protect the super absorbent resin layer and the waterproof coating layer. Water flows from the gaps in the rubber particle layer to the super absorbent resin layer, so that the super absorbent resin layer fully absorbs the water, thereby ensuring the continuous inflow of water.
