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. 1. A method of manufacturing artificial turf that is durable to mechanical stress , in particular in respect to mechanical pulling forces exerted on artificial turf fibers , the method comprising the steps of:creating a polymer mixture comprising at least one polymer and a nucleating agent for crystallizing the at least one polymer, the nucleating agent being an inorganic and/or an organic substance or a mixture thereof,wherein the inorganic substance acting as the nucleating agent consists of one or more of: talcum; kaolin; calcium carbonate; magnesium carbonate; silicate; silicic acid; silicic acid ester; aluminium trihydrate; magnesium hydroxide; meta- and/or polyphosphates; and coal fly ash;wherein the organic substance acting as the nucleating agent consists of one or more of: 1,2-cyclohexane dicarbonic acid salt; benzoic acid; benzoic acid salt; sorbic acid; and sorbic acid salt; 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 at least one polymer within the monofilament, wherein the boosting of the ...
