Abstract

The method includes creating a polymer mixture, wherein the polymer mixture includes a stabilizing polymer, a bulk polymer, a flame retardant polymer combination, and a compatibilizer. The stabilizing polymer and the bulk polymer are immiscible. The stabilizing polymer includes fibers surrounded by the compatibilizer within the bulk polymer. The stabilizing polymer is aramid. The flame retardant polymer combination is a mixture of triazin and melamine. The method further includes extruding the polymer mixture into a monofilament. The method further includes quenching the monofilament. The method further includes reheating the monofilament. The method further includes stretching the reheated monofilament to align the fibers relative to each other and to form the monofilament into an artificial turf fiber. The method further includes incorporating the artificial turf fiber into an artificial turf backing.
