Embodiment 1

[0059] The composite yarn 3 is first prepared by twisting a fibrillated yarn 6 around six monofilament yarns 7 . The fibrillated yarn had a yarn count of 6600 denex and a thickness of 80 μm. The spacing d between the slits is such that the filament width varies, more specifically between about 0.1 and 1.2 mm. Each monofilament yarn has a yarn count of 1400 denex, a thickness of 160 μm, and a width of 1.4 mm. The yarn count of the composite yarn was 15000 denex. The different yarns are all prepared from polyethylene with UV and heat stabilizers and green pigments. The composite yarns are tufted on a backing layer consisting of a woven polypropylene layer and a fiberglass mesh. The gauge of the tufting machine was set at 5 / 8". The average height h of the tufts was about 5 cm. A latex adhesive was applied to the back of the backing layer to hold the tufts in place. The resulting synthetic grass is shown in Figure 4 . In the cross-sectional view of this figure, only a portio...

Embodiment 2

[0061] Composite yarns are prepared by twisting two monofilament yarns around four monofilament yarns. The single tape yarn has a yarn count of 2200 denex and a thickness of 100 μm. The width of the single tape yarn is 2.5mm. The monofilament yarn has a yarn count of 1400 denex and a thickness of 160 μm. The monofilament width is 1.4mm. The yarn count of the composite yarn was 10,000 denex. The composite yarns are tufted on a backing layer consisting of a woven polypropylene layer and a fiberglass mesh. A latex adhesive is applied to the back of the backing layer to hold the tufts in place. This synthetic turf directly resembles natural grass, meaning that no post-fibrillation or abrasion process is required to achieve this appearance.

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...
