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 foamed polyurethane is placed on the precoat, and one or more reinforcing sheets are also embedded within or placed on 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. One or more of the fibrous sheets may be needle felt to provide some of the needed resilience. The turf is cut along lines parallel and perpendicular to the tufting lines to provide tiles, and the tiles are assembled to form the desired turf.
