1. A method for producing an artificial turf fiber, the method comprising:
preparing a liquid core polymer mixture, the core polymer mixture comprising a core polymer and a thread polymer forming beads within the core polymer, the core polymer mixture free of a compatibilizer;
coextruding the liquid core polymer mixture with a liquid cladding polymer component into a monofilament, the liquid core polymer mixture forming a cylindrical core, the liquid cladding polymer component forming a cladding encompassing the core, the cladding having a non-circular profile;
quenching the monofilament;
reheating the quenched monofilament;
stretching the reheated monofilament to deform the beads into threadlike regions; and
providing one or more of the stretched monofilaments as the artificial turf fiber.
