The invention provides for a method of delaying and reducing texture reversion of a textured artificial turf yarn (), characterized by using a stretched and textured monofilament yarn as the textured artificial turf yarn, the stretched and textured monofilament yarn comprising a polymer mixture (), wherein the polymer mixture is at least a three-phase system, wherein the polymer mixture comprises a first polymer (), a second polymer (), and a compatibilizer (), wherein the first polymer and the second polymer are immiscible, wherein the first polymer forms polymer beads () surrounded by the compatibilizer within the second polymer.

Method of delaying and reducing texture reversion of a textured artificial turf yarn

A method for manufacturing an artificial turf fiber includes creating a polymer mixture that includes, 60-99% by weight of an LLDPE polymer and 1-15% by weight of an LDPE polymer. The method further includes extruding the polymer mixture into a monofilament; quenching the monofilament; reheating the monofilament; and stretching the reheated monofilament to form the monofilament into the artificial turf fiber.

Artificial turf fiber with LLDPE and LDPE

The invention relates to a polymer-based artificial turf fiber comprising substances () adapted for protecting the fiber against UV radiation. The substances comprise a hindered amine light stabilizer—HALS and a first and a second UV-absorbent substance. The molecular weights of the first and the second UV-absorbent substances differ from each other by at least 100 g/mol.

Artificial turf fiber with UV protection substances

A method of manufacturing artificial turf creating a liquid polymer mixture, wherein the polymer mixture is at least a two-phase system. A first one of the phases includes a first polymer and a first dye, and a second one of the phases of the polymer mixture includes a second polymer and a second dye. The second dye has a different color than the first dye, the second polymer being of the same or of a different type as the first polymer. The first and the second phase are immiscible, the first phase forming polymer beads within the second phase. The method further includes extruding the polymer mixture into a monofilament including a marbled pattern of the first and second color; quenching the monofilament; reheating the monofilament; stretching the reheated monofilament to deform the polymer beads into threadlike regions and to form the monofilament into an artificial turf fiber; and incorporating the artificial turf fiber into an artificial turf backing.
