Definitions

  • the invention relates to an electrically conductive textile floor covering material according to the preamble of claim 1.
  • a textile floor covering material which consists of an upper non-woven layer made of durable synthetic fibers and an electrically conductive second non-woven layer which is needled in such a way that the wear layer formed from the first non-woven material is not electrically conductive .
  • CH Patent No. 529 542 describes an antistatically finished pile carpet which consists of a base fabric, a walk fiber layer with a layer of antistatic material which at most adjoins the base fabric and a back layer made of a polymeric material.
  • the aim of the invention is to provide an electrically conductive, textile floor covering material in which this disadvantage does not occur.
  • a nonwoven fabric made using needle felting technology which is electrically conductive, is laminated onto the back layer.
  • the advantage is that the flooring material can be laid as a membrane.
  • a heavy coating which consists of electrically conductive plastic, is applied to the surface of the base layer facing away from the wear layer, the back layer is made of a nonwoven fabric that is electrically conductive, and the flooring material is plate-shaped.
  • the advantages of the preferred exemplary embodiment are essentially to be seen in the fact that the floor covering material on the upper side can dissipate any electrical charge that occurs on the upper side, that due to the self-adhesive layer formed as a nonwoven fabric, sound insulation is achieved and a non-slip effect is achieved that a dimensionally stable plate is present, which is easy to lay, and that flat cables up to 2 mm thick can be laid under the plate.
  • the present invention is illustrated by the following example.
  • the flooring material contains a pre-needled fleece made of synthetic fibers and a portion of electrically conductive synthetic fibers, which are needled evenly over the surface.
  • This fleece is needled together with an endless fiber fleece in such a way that a web-shaped material with a wear layer and a base layer is produced.
  • a heavy coating of electrically conductive plastic is applied to the side of the base layer facing away from the wear layer. Due to this heavy coating, pre-punching is required.
  • a backing layer in the form of a nonwoven fabric produced using needle felting technology is provided on the heavy coating, which is made electrically conductive by uniformly distributed electrically conductive fibers and is self-adhesive on the downward-facing surface. This fiber fleece is covered by a film to prevent a reduction in the self-adhesive effect due to soiling.
  • the flooring material is in the form of plates.
  • these panels Due to the heavy coating and the self-adhesive effect of the back layer in the form of the electrically conductive fiber fleece, these panels have very good self-lying properties and are particularly suitable for laying in data centers.
