Definitions

  • the invention relates to an erosion protection and planting mat according to the features of the preamble of claim 1.
  • the invention has for its object to simplify this erosion control and planting mat in the manufacture.
  • the fabric and the fleece arranged on the underside are according to the invention by Needles connected to each other, the connecting means being individual fibers of the fleece arranged on the underside of the fabric, which are pierced into the threads of the fabric and are held there with the help of special machines and needles with barbs.
  • the fibers of the nonwoven are thus used as connecting means, so that no additional connecting means are required and the manufacture of the mat is thus considerably simplified.
  • the number of fibers holding the fabric together with the nonwoven is so small that when moisture (rain) occurs and the weight of the nonwoven increases due to water absorption, the individual connecting fibers of the nonwoven tear under the influence of moisture and moisture and the associated increase in weight of the nonwoven or tear out of the tissue.
  • DE-OS 3400696 It is known from the non-generic DE-OS 2158914 to firmly connect two identical nonwovens used for planting to one another by needling.
  • DE-OS 3400696 also discloses a composite material consisting of two layers of fiber peat of the same material, which are connected to one another by fibers or threads.
  • the problems on which the invention is based do not occur here, since the composite material consists in each case of two identical substances which behave identically under weather conditions.
  • a coarse-mesh fabric 1 made of sisal or coconut fibers has on its underside a fleece 2, which is preferably constructed from dark or dark-colored fibers.
  • Coarse-mesh fabric in the sense of the present invention is understood to mean one that has relatively large pore volumes between the threads, a so-called leaky fabric.
  • Plant seeds 3 are embedded in the above-mentioned fleece 2, and a fertilizer can expediently also be included here.
  • Fabric 1 and fleece 2 are connected to one another in the factory by individual fibers which come from the fleece and are held in place in the fabric. These connecting fibers tear under weight load at the moment when the fleece, weighted by rainwater, multiplies its weight and sinks to the floor to be protected.
  • FIG. 2 now illustrates how the mat shown in FIG. 1, manufactured at the factory, is laid on a floor 6 to be fastened, this floor being strewn with relatively large stones 7.
  • the mat is laid so that it sags between adjacent stones 7 and rests on the floor to be fastened.
  • anchors can be attached to the floor at various points, with which the mat is then permanently connected.
  • connection fibers tear under the weight of the rain-soaked fleece and thus the connection between fleece 2 and fabric 1 is interrupted, so that the fabric shrinks under the aforementioned weather conditions and is therefore shortened between two adjacent supports , here between the stones 7, is raised, but with seeds and event.
  • Fertilizer fleece 2 now remains on the ground 6 and the germinating seeds or their roots find the conditions necessary for their development.
  • a mat in which fleece and fabric are connected with threads or yarns of a conventional type shows the picture that is illustrated schematically in FIG. 4: the mat lifting between two adjacent supports (stones 7) as a result of the shrinkage inevitably entrains this their bonded fleece 2, it lifts it off the ground 6, and the roots 8 of the germinating seeds hang freely in the air, withering soon. Since the shrinkage process mentioned is irreversible, the germinating seeds cannot develop in this case, the seeds cannot fulfill their intended function.
