摘要： The invention provides for a method of manufacturing artificial turf (1000), The method comprising the steps of: —creating (100) a polymer mixture (100, 400, 500) comprising at least one polymer and a nucleat ing agent for crystallizing the at least one polymer; —extruding (102) the polymer mixture into a monofilament (606); —quenching (104) the monofilament; —reheating (106) the monofilament; —stretching (108) the reheated monofilament to form the monofilament into an artificial turf fiber (1004), wherein during the stretching the nucleating agent boosts the creation of crystalline portions of the at least one polymer within the monofilament; —incorporating (110) 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.
