A cork-based infill mixture for an artificial turf system, wherein the infill mixture comprises a predominance of cork particulates and a quantity of smooth, hard granules interspersed between the particulates.

Infill mixture for artificial turf

A foamed fabric comprising filaments of closed-cell foam of cross-linked polymeric material is formed by integrating the filaments into a precursor textile and subsequently foaming the material at a foaming temperature at which the filaments expand. The foamed fabric can be used for protective garments, pads, mats and the like.

Use of a foamable polymer filament, and foamed fabric

The invention relates to a synthetic monofilament fiber for use in an artificial lawn, said synthetic fiber having a width greater than the thickness of the synthetic fiber and being provided with solid thickened parts at its free ends, and a central part between the thickened parts comprising a curved section and having a substantially uniform thickness, seen in transverse direction, the synthetic fiber having a thickness/width ratio such that the synthetic fiber can buckle locally upon being subjected to an external load. The invention further relates to an artificial lawn with a backing to which one or more synthetic fibers according to the invention are attached.

Artificial grass fibre and artificial lawn comprising such a fibre

The present invention relates to an artificial turf suitable for sports fields including a substrate to which first artificial grass fibers are attached and a granular infill, which is provided between the first artificial grass fibers and which is made of a recyclable synthetic material. The invention also relates to an improved granular infill for use in an artificial turf suitable for sports fields.

Artificial grass turf and infill for sports fields

An artificial fiber for use in an artificial grass sports field is disclosed wherein, seen in a transverse sectional direction of the fiber, at least part of the fiber is provided with a stiffness-enhancing portion extending in the longitudinal direction thereof. The artificial fiber includes at least two fiber flange portions, at least one fiber flange portion forming the stiffness-enhancing portion, while at least two fiber flange portions have a uniform thickness. The improved artificial fiber is less flexible and consequently exhibits less tendency to deform to a flat orientation, but does not increase the risk of injuries to players or have an adverse effect on the playing characteristics of the field. Also disclosed is an artificial grass lawn, suitable for sports fields, having a substrate to which one or more artificial fibers of the invention are attached.

Artificial fiber for use in an artificial grass sports field

The invention relates to an artificial lawn, in particular for an artificial grass sports field comprising an artificial mat built up of a carrier to which artificial glass fibers are attached. The object of the invention is to provide a new type of artificial lawn, which in particular obviates the need to use an infill material, without this having an adverse effect on the playing characteristics of the sports field. According to the invention, the carrier is at least in part provided with at least one additional material component, which additional material component imposes a permanent volume increase on said part of the carrier under the influence of an external stimulus after being provided in the artificial mat. The use of an additional material component, which imposes a permanent volume increase on at least a part of the carrier, makes it possible to create an artificial lawn having an additional damping property, which has a positive effect on the playing characteristics of the sports field, such as the absorption of shocks, the restitution of energy and the vertical deformation and which furthermore reduces the number of player injuries.

Artificial lawn for artificial grass sports field

The invention relates to an artificial grass fiber in particular for use in an artificial mat for an artificial lawn, which artificial grass fiber is made of at least one synthetic material. The invention also relates to an artificial mat, in particular for use in an artificial grass sports field, which artificial mat is built up of a carrier to which at least artificial grass fibers according to the invention are attached. The object of the invention is therefore to provide an improved artificial grass fiber which on the one hand can be produced by means of the existing techniques and which on the other hand reduces the number of injuries on the field. According to the invention, the artificial grass fiber to that end furthermore comprises at least one additional material component, which additional material component imposes a permanent volume increase on the artificial grass fiber under the influence of an external stimulus after the artificial mat has been provided with the artificial grass fiber. Thus it is possible to create an artificial mat for a lawn, which can be produced by means of the standard production techniques and wherein the artificial grass fiber in question foams and transforms into, for example, a dampening layer after the manufacture of the artificial lawn, which layer improves or influences the playing characteristics of the sports field, such as the absorption of shocks, the restition of energy, the vetical deformation, grip and ball bounce and which furthermore reduces the number of player injuries.

Artificial grass fibre and artificial lawn thereof

The invention relates to a composite artificial grass fiber for use in an artificial lawn, in particular an artificial grass sports field, which artificial grass fiber is made up at least of several monofilament fibers. The invention further relates to an artificial lawn, in particular an artificial grass sports field built up of a substrate to which composite artificial grass fibers according to the invention are attached. The invention also relates to a method for manufacturing a composite artificial grass fiber according to the invention, in particular for an artificial lawn, which comprises the steps of manufacturing several monofilament fibers and forming said several monofilament fibers into a composite artificial grass fiber. The object of the invention is to provide a composite artificial grass fiber as well as an artificial grass sports field comprising such an artificial grass fiber, which makes it possible to apply and distribute infill material between the composite fibers in a simpler manner without the eventual playing characteristics of the artificial grass sports field being adversely affected. According to the invention, the artificial grass fiber is to that end characterized in that the artificial grass fiber further comprises an additive made of a decomposable material, which holds said several monofilament fibers together temporarily.
