subject: Artificial Grass For Sport Fields [print this page] The filling of the spaces between the fibres of an artificial grass manufacturer lawn has a number of drawbacks. Not only is the construction of such an artificial grass field more labour-intensive, but in addition, an artificial grass field filled with a granular material requires maintenance after its construction. The originally uniform distribution of the damping material is disrupted by the weather influences or by the intensive use that is made of the field. In the latter case, areas are formed in the artificial grass field where hardly any filling material remains, in particular areas which are played on very intensively, for example the goal area, which has an adverse effect on the play itself, but which also causes the risk of injury to increase. In a sand-filled artificial grass field, frequent refilling with sand is necessary, therefore.
The object of the invention is to provide an artificial grass manufacturer field which is substantially free of maintenance and which does not exhibit the aforesaid drawbacks. In accordance with the invention, the artificial grass lawn is characterized in that said base layer comprises a material having damping properties, which is present thereon and/or therein. The drawbacks of filling the spaces between the artificial fibres with damping material are thus completely overcome, so that an artificial grass field obtained in this manner is substantially free of maintenance. Moreover, the damping material can be worked into the artificial grass lawn during the manufacturing process already, so that the artificial grass manufacturer field can be constructed in one operation. This leads to a considerable saving of labour.
According to one embodiment of the invention, the material consists of further synthetic fibres which are worked into the base layer. The length of said further artificial grass manufacturer fibres is preferably smaller than that of the first artificial grass fibres, said length being 10%-50% of the length of said first artificial grass fibres, for example. In another embodiment, said further fibres consist of one or more bundles of monofilaments or of twisted fibres.
