  • Patent number: 7399514
    Abstract: The present invention provides new types of synthetic turf. The synthetic turf includes a pile fabric having a backing (1) and tufts (2) projecting therefrom. In one embodiment, at least a number of the tufts are made of a composite yarn formed by at least one fibrillated yarn (6) together with a number of individual filament yarns (7), in particular with so-called monofilament or monotape yarns. The fibrillated yarn and the individual filament yarns are preferably made of polyethylene so that the synthetic turf is sliding-friendly. In another embodiment, at least a number of the tufts are made of a composite yarn formed by monotape yarns twisted together with a number of the monofilament yarns. The monofilament and monotape yarns are preferably made of polyethylene so that the synthetic turf is sliding-friendly.
