Abstract
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.
