20090098378 | Artificial Fiber for Use in an Artificial Grass Sports Field - 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. | 04-16-2009 |
20090252899 | Artificial Lawn, in Particular an Artificial Grass Sports Field - The invention relates to an artificial lawn, in particular an artificial grass sports field, comprising a substrate to which artificial grass fibres provided with additives are attached, which additives undergo a color change in response to an external stimulus. The object of the invention is to provide an artificial lawn as referred to in the introductory paragraph which is capable of displaying a range of colors in a simpler and more effective manner. According to the invention, the artificial grass fibres provided with an additive are attached to the substrate in the form of various groups of artificial grass fibres, each provided with a specific additive, wherein each specific additive of a group of artificial grass fibres undergoes a color change in response to a specific external stimulus. In this way a more versatile artificial lawn is realized, which can be used for various applications, and wherein a new group of artificial grass fibres can be activated to effect the color change each time by using a different, specific external stimulus. | 10-08-2009 |
20090252900 | Artificial grass fibre and artificial lawn thereof - The invention relates to an artificial grass fibre in particular for use in an artificial mat for an artificial lawn, which artificial grass fibre 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 fibres according to the invention are attached. The object of the invention is therefore to provide an improved artificial grass fibre 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 fibre to that end furthermore comprises at least one additional material component, which additional material component imposes a permanent volume increase on the artificial grass fibre under the influence of an external stimulus after the artificial mat has been provided with the artificial grass fibre. 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 fibre 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. | 10-08-2009 |
20100021660 | Artificial lawn for 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 fibres 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. | 01-28-2010 |
20100040808 | SYNTHETIC FIBER AND METHOD OF MANUFACTURE - The present invention relates to a method for producing a synthetic fiber for use in an artificial grass sports field, including the steps of supplying a layer of synthetic material; and obtaining the synthetic fiber from the layer of synthetic material, wherein the layer of synthetic material comprises at least two layers of different synthetic materials, using a co-extrusion process. The invention also relates to such a synthetic fiber and to an artificial lawn suitable for sports fields, including a substrate to which synthetic fibers according to the invention have been attached. | 02-18-2010 |
20100047487 | COMPOSITE ARTIFICIAL GRASS AND METHOD FOR MANUFACTURING SAME - The invention relates to a composite artificial grass fibre for use in an artificial lawn, in particular an artificial grass sports field, which artificial grass fibre is made up at least of several monofilament fibres. 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 fibres according to the invention are attached. The invention also relates to a method for manufacturing a composite artificial grass fibre according to the invention, in particular for an artificial lawn, which comprises the steps of manufacturing several monofilament fibres and forming said several monofilament fibres into a composite artificial grass fibre. The object of the invention is to provide a composite artificial grass fibre as well as an artificial grass sports field comprising such an artificial grass fibre, which makes it possible to apply and distribute infill material between the composite fibres 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 fibre is to that end characterised in that the artificial grass fibre further comprises an additive made of a decomposable material, which holds said several monofilament fibres together temporarily. | 02-25-2010 |
20110091663 | SUBSTRATE FOR SPORTS AND RECREATION FIELDS, A BACKING FOR AN ARTIFICIAL LAWN PROVIDED WITH SUCH A SUBSTRATE AND A COMPOSITION FOR SUCH A SUBSTRATE - The invention relates to a substrate for sports and recreation fields, in particular artificial grass sports fields that contain granular infill material, which substrate comprises at least one component that can leach out upon contact with water and which further comprises a binder material for binding the leached-out component. | 04-21-2011 |
20110262665 | ARTIFICIAL GRASS FIBRE AND ARTIFICIAL LAWN COMPRISING SUCH A FIBRE - The invention relates to a synthetic fibre of the monofilament type for use in an artificial lawn, which synthetic fibre has a width greater than the thickness of the synthetic fibre. | 10-27-2011 |
20120156401 | ARTIFICIAL FIBER FOR USE IN AN ARTIFICIAL GRASS SPORTS FIELD - 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.
