ABSTRACT:
Artificial athletic turf has a simulated grass surface provided by tufting strips into a backing fabric. The tufts are held in place by a precoat of polyurethane, and a reinforcing sheet is embedded within the precoat to provide tear resistance. A formed polyurethane is placed on the precoat, and one or more reinforcing sheet are also embedded within the foamed polyurethane. The strips are hydrophobic plastic with strength to prevent damage, and the coatings are polyurethane reinforced for tear resistance, which also yields a resilience as needed for an athletic mat. A hole can be cut into the mat, and the hole reinforced with a sleeve, to receive a tee for use as a golf mat.
