Definitions

  • the invention relates to an artificial turf with at least partially hollow straws made of plastic, which are fastened in a carrier layer.
  • the backing layer is a synthetic fiber fabric in which the fiber tapes are embedded.
  • the fiber tapes are usually incorporated by tufting, rustling or other mechanical processes, so that a lawn carpet is created.
  • PP, PA, PS or PE are mostly used as material for the stalks, whereby these plastics are colored green or in a different color.
  • the fiber or lawn tapes can also be connected to form tufts and anchored as such units in the carrier material.
  • the structure of the stalks can be smooth, curled or wavy, depending on the intended use.
  • the length of the lawn straps is different and is adapted to use.
  • the object of the invention is to provide an artificial turf which can absorb and store more water, the stored water only being released when it is entered and intended to be available to improve the sliding properties.
  • the stalks can absorb water from rain, fog, air humidity and humidification systems via capillary forces.
  • the water stored in the straws is largely protected from sunlight and wind and is only released when you enter it when the straws are squeezed together.
  • the advantage of the hollow stalks is that a multiple of the amounts of adhesive water can be stored and the water can be selectively, i.e. when it is needed, delivered and available.
  • the tubes are U-shaped and, for example, are tufted or snapped into the base fabric, the legs of the U having their openings pointing upwards in order to be able to absorb water.
  • the conventional lawn tapes are tied together to form tufts of straw.
  • This technique can also be used with straw tubes, although the U-shaped tubes are pinched off in the base tissue. This means that the air in the respective leg of the U-shaped tube cannot escape when water penetrates, which in some circumstances can hinder the absorption of the water. It is therefore necessary to provide at least one ventilation opening in the wall of the tube, this opening advantageously being provided directly above the carrier layer.
  • the opening or the openings in the straw wall are preferably chosen to be so small that the stored water cannot flow out through these openings again.
  • the U-shaped straw tube can also be technically fixed as a non-clamped U in the carrier tissue.
  • the straw tube U is then glued on the underside using suitable plastics in the carrier fabric.
  • the backing layer additionally has a water storage layer through fleece or foam
  • openings can be arranged exclusively or additionally in the region of the backing layer and / or water storage layer.
  • the hollow straw is then able to absorb moisture from the carrier layer due to the capillary forces. This is especially so an advantage if the water has already been squeezed out of the straws during play, but there is still water in the storage layer. As a result, the hollow straw can also be refilled during game operation.
  • a hydrophilic plastic is preferably used for the production of the tubes. It is also possible to provide the inside of the tubes with a hydrophilic layer.
  • the tubes can be produced, for example, by means of extrusion processes.
  • the straws 4 are designed as U-shaped tubes 7, the legs of the tubes 7 being arranged upright, so that the openings 8a, 8b point upwards and receive raining water and inside the Can save tubes.
  • the stored water 10 can completely fill the tubes.
  • FIG. 2 A further embodiment is shown in FIG. 2, in which the stalks 4 or the tubes 7 are connected to one another into stalk tufts 5. These tufts are prefabricated by connecting the tubes together in the middle in area 6. The result of this is that the tubes 7 may be clamped there (not shown in FIG. 2), so that a passage of liquid is prevented. This would have the result that 6 jams air inside the tube in front of the connection point, which air could prevent further penetration of the water.
  • at least one opening 9 is provided, which is located directly above the surface of the carrier layer 2. When the water penetrates through the openings 8a, 8b of the tubes 7, the air can escape here. The diameter of the openings 9 is so small that the water which has penetrated cannot flow off.
  • FIG 3 shows a carrier layer 2 which additionally has a water storage layer 3.
  • a tuft of straw 5 is also anchored in this layer, in which openings 11 are arranged in the region of the carrier layer 2 / water storage layer 3.
  • the tubes 7 can absorb liquid from the water storage layer 3 via the openings 11.
