Definitions

  • the invention relates to a floor covering designed as pile fabric for sports surfaces, in particular artificial turf, with an opening-bearing and therefore water-permeable carrier web, a fibrous material web needled onto the latter and with pole elements attached to the carrier web and forming the pole with their free end regions.
  • a similar floor covering which has the features of the preamble of claim 1, is known from DE-A-29 35 387.
  • the invention relates to such a floor covering of the type mentioned above, in which the pole elements are knitted into the carrier webs.
  • Known floor coverings in the form of a pile fabric, in particular in the form of artificial turf are produced as tufted fabrics with a textile carrier web, as a knitted fabric, knitted fabric or the like and then optionally provide the carrier web with a partial or full-area back coating, in the latter case, however, being ensured by openings in the back coating must that the artificial turf is permeable to water; the latter is important because in the case of such a floor covering laid outdoors, rain and melt water must be able to flow down through the floor covering, but also the water applied from above when the floor covering is moistened - in this connection it must be pointed out that optimal example properties of such a floor covering only arise when the surface of the covering is somewhat damp.
  • the floor covering for sports surfaces known from DE-A-38 35 880 which is designed as a pile fabric, is also unsatisfactory; it has a water-permeable carrier web, to which upwardly projecting pole elements are attached with their free end regions, as well as under the carrier web and at a distance therefrom a nonwoven web, which is also water-permeable, and in the space between the carrier web and nonwoven web. Web are connected to the latter, approximately hemispherical cushion elements made of closed-cell plastic foam, which should ensure a satisfactory tread elasticity of this known flooring.
  • the space between the carrier web and the nonwoven web left free by these cushioning elements is filled with a granulate filling, which is in particular a mixture of sand and rubber granulate.
  • the nonwoven web and the granulate filling are intended to ensure a certain water retention capacity of this known floor covering, to which the upholstery elements cannot contribute because, as mentioned, they consist of a closed-cell plastic foam.
  • Sand, rubber granulate or a mixture of these two materials can hardly store water, and water retained by the nonwoven web will hardly reach its surface again with this edged flooring, since there is a gap between the nonwoven web and the recorded surface of the flooring non-water-permeable upholstery elements, the lower, flat surfaces of which cover most of the nonwoven web.
  • this object can be achieved in that the fiber material web is arranged on the underside of the carrier web and, when the fiber material web is needled, tufts of fiber protrude upward from the fiber material web through the carrier web between the free end regions of the pole elements.
  • the fibrous material web has a double function: on the one hand, it acts as a water reservoir for water accumulating on the surface of the covering and which has passed down through the water-permeable carrier web, and on the other hand, based on a capillary action, water becomes through the fiber tufts protruding through the carrier web transported by the fibrous material web, which acts as a water reservoir, through the carrier web back into the area of the covering surface as soon as it threatens to dry, especially when the floor covering is being used and pressure is exerted on it from above, resulting in a compression of the fibrous material web in the recorded area.
  • the water storage and retention capacity of the fibrous material web can be selected by an appropriate choice, for. B.
  • the fibrous material web it could, for. B. is a felt or a knitted fabric, but even better results can be achieved with a nonwoven fabric that can store a multiple of its own weight in water.
  • the needling of a nonwoven fabric on the carrier web of an artificial turf is known per se (DE-A-29 35 387); in this known artificial turf, however, the nonwoven fabric is needled onto the upper side of the carrier web of the artificial turf designed as tufted goods, and the tufts of fibers pushed through the carrier web during the needling of the nonwoven fabric protrude downward from the carrier web between the anchoring feet of the pole elements of this known artificial turf.
  • the nonwoven should serve the purpose of covering the carrier web so that its color is not visible from above, and secondly the fibers pressed through the carrier web from top to bottom have a coating compound applied to the underside of the carrier web a repellent effect on the coating composition, so that the openings in the carrier web required for the water permeability of the artificial turf are at least not completely closed by the back coating composition.
  • the task and arrangement of the nonwoven fabric in this known artificial turf are completely different than in the floor covering according to the invention.
  • the fibrous material web could be needled onto the carrier web from below before the pole elements, e.g. B. by tufts, are introduced into the carrier web.
  • the pole elements have anchoring feet arranged on the underside of the carrier web, which are covered by the fiber material web.
  • pole elements introduced into the carrier web by tufts are then better fixed in the carrier web, and in addition, the anchoring feet of the pole elements are not subject to the risk of being chafed due to the use of the flooring when laying the flooring on a rough surface.
  • a floor covering according to the invention can be produced without an adhesive or a back coating material, so that the floor covering according to the invention can be produced as a fully recyclable material.
  • a fiber material web impregnated to stiffen its fibers is recommended.
  • a fiber material web impregnated with a latex emulsion is particularly advantageous, for the following reason: a sports surface floor covering must be replaced after about 5 to 10 years; within such a period of time, however, latex decomposes due to aging and is washed away when the floor covering is sprinkled, so that only pure plastic material has to be worked up when the floor covering is recycled.
  • an additional shape-stabilizing material web can also be needled onto the carrier web or the knitted back at the same time as the fiber material web, e.g. B. a mesh, a nonwoven fabric or the like.
  • the drawing shows a carrier web 10 designed as a tufting base fabric, which was produced in the present case from plastic tapes 10a and whose water permeability can be ensured in a variety of ways, e.g. B. by the width and density of the plastic ribbon 10a, d. H. by the transverse spacing of the plastic tapes forming the warp and weft threads from one another. Pole elements 12, the anchoring feet 12 a of which lie on the back of the carrier web 10, were introduced into the carrier web 10 using the tufting process. A nonwoven fabric layer 14 was then needled onto the carrier web 10 from below, as a result of which holes 10b were created in the carrier web 10 and pushed through these fiber tufts 14a.
