A method for producing an artificial turf fiber, comprising:

    preparing a core polymer mixture from a core polymer and a thread polymer forming beads within the core polymer;coextruding the core polymer mixture with a cladding polymer component into a monofilament, the core polymer mixture forming a cylindrical core, The cladding polymer component forming a cladding encompassing the core with a non-circular profile;quenching the monofilament;reheating the quenched monofilament;stretching the reheated monofilament to deform the beads into threadlike regions; andproviding one or more of the stretched monofilaments as the artificial turf fiber.
