High quality artificial grass for FIFA

The present invention relates to an artificial grass manufacturer turf carpet and an artificial grass turf system including such a carpet.

From the prior art, many artificial grass turf systems are known.

Recently, the Federation Internationale de Football Association (FIFA) allowed the use of artificial grass manufacturer turf systems for soccer. These artificial grass turf systems, in general, are "third generation" turf systems, having synthetic grass fibers of considerable length, for example, up to 70 mm, and a thick infill layer on top of the ground structure between the grass fibers. These artificial grass turf systems generally have an infill layer of rubber granules or particles, sometimes mixed with sand.

Many different aspects are involved in artificial grass manufacturer turf systems. These aspects include such things as: ball/surface interaction (vertical ball rebound, ball roll, etc.), player/surface interaction (such as deformation, slip resistance, traction, etc.), and also shock absorption and energy restitution.

The present invention aims to provide an improved artificial grass manufacturer turf carpet and an artificial grass turf system including such a carpet.

In particular, the present invention aims to provide an artificial grass manufacturer turf system highly suitable for sports, in particular for soccer, but also for American football, rugby and other ball or contact sports.

In an installed artificial grass manufacturer turf system having an infill layer on top of the base layer fibers grass, it is likely that some infill material will enter into the interstices between the base layer fibers and grass fibers in the zone of the base layer. It is preferred that the density of the fibers in the base layer is such that when considering the volume of the base layer, the base layer volume contains less than about 30% of its volume, preferably less than about 20%, of infill material.

Also by using the weaving technique, a reliable locking can be obtained between the ground structure, on the one hand, and the base layer fibers and grass fibers on the other hand. This avoids the problem of fibers coming loose from the turf system, as is experienced in prior art tufted artificial grass manufacturer carpets.

. A woven artificial grass manufacturer turf carpet comprising: a ground fabric comprising a fabric yarn and having an upper surface, synthetic grass fibers woven integrally with said ground fabric, which synthetic grass fibers form a grass surface of said artificial grass turf, and synthetic base layer fibers woven integrally with said ground fabric at positions between the synthetic grass fibers, said base layer fibers having a lower height than said grass fibers.
