Definitions

  • the invention relates to a floor covering sheet designed as a pile for sports surfaces, in particular an artificial turf, with an opening-bearing and therefore water-permeable carrier sheet, with pole elements attached to the latter, forming the pole, and with a thick-elastic plastic layer made of an open-cell foam plastic arranged on the underside of the carrier sheet.
  • So-called artificial turf has become widely used as floor coverings for sports surfaces, which are knitted, knitted, woven, woven or tufted textile products made from plastic tapes and / or plastic yarns in the form of a so-called pile fabric.
  • the pole elements simulating the blades of grass are usually made from plastic tapes which penetrate the carrier web and are fixed in it by a textile integration and / or (the latter in particular in the case of so-called tufting goods) by a partial or full-area back coating of the carrier web by means of a plastic compound.
  • the carrier sheet of known artificial turf Since the requirement is placed in particular on outdoor sports surfaces that the flooring is permeable to water, the carrier sheet of known artificial turf has openings, and with a partial back coating the latter does not remove the water permeability of the flooring.
  • a full-surface back coating in the form of a thick, elastic plastic layer are known, which is a plastic layer made of closed-cell foam plastic; In such a case, the back coating must be perforated to make the floor covering permeable to water.
  • the actual subject of DE-A-38 35 880 is also an artificial turf floor covering, the upper side of which is formed by a pole which simulates the blades of grass and which is anchored in an underlying, water-permeable carrier web.
  • a nonwoven web is arranged at a distance below this carrier web, which, like the carrier web, should be permeable to water, but should also have water-storing properties.
  • This nonwoven web carries on her The upper side is arranged in a grid pattern, in particular hemispherical cushion elements made of a closed-cell plastic foam, and the rest of the space between the carrier web and the nonwoven web is filled with pourable material (granules). Water stored in the nonwoven web can therefore at most pass from the nonwoven web up to the carrier web due to any capillary effects of the granulate bed.
  • the invention had for its object to provide a water-permeable floor covering designed as a pile for sports surfaces, in particular an artificial turf, which also has water-storing properties, but which, after moistening the surface of the covering, maintains the desired example properties longer than the known floor coverings described above.
  • this object can be achieved according to the invention in that a storage layer made of a nonwoven fabric, a needle felt or a heavy fabric is arranged on the underside of the plastic layer and the plastic layer is designed such that it is covered when walking on the floor covering sheet has a pump effect effecting water transport from the storage layer to the carrier web.
  • a nonwoven fabric, a needle felt or a heavy fabric can retain much more water at the same volume, ie store it than the known open-cell foam plastics, so that with the help of such a storage layer the floor covering web according to the invention remains moist longer than the known floor coverings described above.
  • the according to the Invention provided and a pumping effect plastic layer leads to the fact that the return transport of the water originally accumulated on the top of the floor covering from the water reservoir to the upper regions of the floor covering takes place precisely when the desired exemplary properties are required, namely while the floor covering is being used.
  • the plastic layer made of an open-cell foam plastic consists, for example, of a latex foam, a polyurethane foam or a foam rubber.
  • the storage layer is formed by a nonwoven fabric, which can adhesively store several times its own weight in water.
  • Nonwoven fabrics made of a non-rotting material are preferred, which of course also applies to all elements of the floor covering according to the invention.
  • the pole elements have anchoring feet arranged on the underside of the carrier web, it being particularly advantageous if these lie between the carrier web and the foam plastic layer;
  • the foam plastic layer in particular laminated to the back of the carrier web, serves to improve the fixation of the pole elements in the carrier web, and the anchoring feet of the pole elements are covered by the foam plastic layer and the storage layer, so that they do not become the same when laying the floor covering on a rough surface Are at risk of being chafed as a result of the floor covering being used.
  • butadiene styrene is recommended as the plastic for the foam pumping layer which brings about the return pump effect;
  • the carrier web, pole elements, foam plastic layer and storage layer are made of the same plastic.
  • the drawing shows a carrier web 10, which is a basic tufting product, in particular a fabric made of plastic tapes.
  • pole elements 12 are anchored, which were introduced into the carrier web 10 by tufts and are formed by plastic tapes. In side view, they are approximately U-shaped and each form an anchoring foot 12a on the underside of the carrier web.
  • a foam plastic layer 14 is laminated to the underside of the tufted goods 10, 12, which consists of an open-cell foam plastic and is, according to the invention, elastic in thickness.
  • a nonwoven layer 16 is laminated to the underside of the foam plastic layer 14, which layer forms the water storage layer according to the invention.
  • the desired storage capacity can be achieved and set by the thickness, density, structure and type of fiber material of the nonwoven layer 16.
  • the pores of the foam plastic layer 14 enable water to be transported by gravity through the foam plastic layer 14 into the fiber fleece layer 16 and as a result of the capillary action or the pumping action that occurs when the floor covering is covered, from the fiber fleece layer 16 back into the actual artificial turf layer 10, 12 and in particular through it water-permeable carrier web 10 through to the surface of the artificial turf layer.
  • the water permeability of the carrier web 10 is also to be noted that this can be ensured and adjusted in a variety of ways, for. B. by relatively thick needles when tufting, by the type and density of the textile material used for the production of the carrier web 10, for. B.
