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. The combination of a fibrillated yarn and individual filament yarns or the combination of monofilament and monotape yarns in a composite yarn allows immediate achievement of the look of natural grass, that is, without post-fibrillation, and avoids any visible difference in wear pattern between the different types of yarns. In another embodiment, the invention also provides improved particulate material for use as infill material for top-dressing a synthetic turf.

Description

field of invention

[0001] The present invention relates to synthetic turf which is a piece of pile fabric having a backing and tufts protruding from the backing, wherein the tufts comprise a monofilament yarn portion and at least one fibrillated yarn portion, said Fibrillated yarns consist of ribbons of transversely interconnected filaments exhibiting longitudinal slits, the monofilament yarns and interconnected filaments being dimensionally similar to blades of grass. The invention also relates to synthetic turf having a fleece fabric having a backing and tufts protruding from the backing, wherein the tufts comprise monofilament yarn portions comprising extruded monofilament yarns and monofilament yarns. Taped, monofilament, and single-taped yarns are similar in size to blades of grass. Background of the invention

[0002] Synthetic or artificial turf is increasingly being used to replace natural turf on sports fields such as football, rugby, tennis, golf, hockey, baseball...
