Abstract
A method of manufacturing artificial turf includes the steps of: creating a polymer mixture including at least one polymer and a nucleating agent for crystallizing the at least one polymer, extruding the polymer mixture into a monofilament; quenching the monofilament; reheating the monofilament; stretching the reheated monofilament to form the monofilament into an artificial turf fiber, wherein during the stretching the nucleating agent boosts the creation of crystalline portions of the polymer within the monofilament; incorporating the artificial turf fiber into an artificial turf backing, thereby mechanically fixing the monofilaments of the arranged artificial turf fibers in the artificial turf backing.
