  • Publication number: 20230183888
    Abstract: 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 of a different color than the first dye. 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.
