Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • Plastic films and plastic or rubber coated textiles such as. B. synthetic leather or weather clothing have the advantage of being absolutely waterproof. However, they have the great disadvantage that they have little or no breathability.
  • such materials require a certain level of water vapor permeability, while at the same time a high level of waterproofness is required.
  • the water vapor permeability essentially depends on the number of perforations per unit area and their absolute size. The watertightness is determined by the size of the holes.
  • the object of the invention is therefore to provide a method by means of which materials that are electrically non-porous or difficult to portray can be made breathable with high water tightness.
  • FIG. 1 shows, on an enlarged scale, a section of a material web which is based on a textile material 1 onto which an electrically porous plastic film 2 is laminated.
  • any other breathable carrier such as. B. a fleece or paper.
  • a carrier can also be dispensed with.
  • the foil-clad textile material 1 shown in FIG. 1 has already been mechanically perforated in a first process step by a well-known needling process.
  • the plastic film 2 is provided with a large number of closely adjacent fine punctures 3.
  • the textile material 1 is also pierced in the process, but the punctures 3a are lost in the loose textile fabric.
  • the punctures 3 have a diameter even when using the finest needles, which ensures good breathability but does not guarantee watertightness.
  • the surface of the plastic film 2 is coated with a thin closed support 4 made of an electrically porous material, preferably a plastic. This is sprayed on in liquid or paste-like form in a known manner or applied to the film surface by an applicator.
  • the entire material web is subjected to a fine poring process in a third process step.
  • This can e.g. B. by an arrangement according to DE-OS 28 30 326, in which the support or layer 4 is provided in the area of the punctures 3 with the finest pores 5.
  • one or more pores 5 can be introduced per puncture 3.
  • FIG. 5 shows section A of FIG. 2 on an enlarged scale.
  • the illustration clearly shows the needled plastic film 2 with the punctures 3. These are covered by layer 4 to the outside.
  • the desired breathability with simultaneous high water tightness is provided via the finest pores 5 introduced into the layer 4.
