Definitions

  • the invention relates to a shield against Basic textile material serving electromagnetic waves with components arranged thereon from an electrical conductive material.
  • Such conductive textiles for protection against electromagnetic fields are known through use and For example, in the publication Koch, M .: conductive Textiles for protection against electromagnetic fields, Denkendorf Colloquium “Technical Textiles", January 2001. Thereafter, such conductive Textiles are made by a metal coating the tissue surface; another manufacturing option is given by the fact that for the production of the Fabric used yarn metal filaments or metal fibers contains.
  • the invention is based on textiles Woven fabrics from conventional non-conductive yarns on which only components from an electrically conductive Material are attached.
  • This is the known textile fabrics to form a grid in the fabric woven-in bundle of metal fibers, that is, one by one metal mesh applied to textile fabric, its Mesh size is usually between 2 and 15 mm and is therefore much larger than the mesh size of the Base fabric.
  • the invention is therefore based on the object to provide generic textile fabric, which is a frequency selective shield electromagnetic fields.
  • the basic idea of the invention provides that on the basic textile material each from a continuous, thread consisting of the electrically conductive material manufactured geometric structures in a regular Distribution without mutual contact, their dimensions to half the wavelength of the selectively reflective frequency of electromagnetic waves is coordinated.
  • the invention meets the requirement of a frequency selective shielding in that the Formation of the geometric structures on the half Wavelength of the wavelength to be selectively reflected is voted.
  • the shielding effect is thereby ensured that to produce the geometric Structures a continuous, from the electrically conductive Material of existing thread is used.
  • the invention is applicable to basic textile materials, especially those made from a woven fabric, a knitted fabric or a nonwoven fabric.
  • the invention provides that those made from the uninterrupted thread Structures by embroidery on the textile base material are upset. This has the advantage that the production of conventional non-conductive yarn existing basic textile material and the application of Shielding structures in sequential and to be carried out independently of one another Manufacturing steps can be made.
  • the mutual distance the structures are mutually determined on the one hand, that the frequency selective to be reflected electromagnetic waves between the geometric Not going through structures, but on the other hand straight is minimized so that mutual interference the frequency selective reflection properties of the Structures is excluded.
  • the geometric structures each from a symmetrical Cross with legs of the same length, where the Total length of two legs of the respective cross of half the wavelength of the corresponds to the reflecting wave frequency.
  • the geometric Structures consist of a circle.
  • the arrangement of the individual crosses 11 on the textile Tissue surface 10 is such that the Leg 12 of two crosses 11 overlap, but that no contact and thus electrically conductive connection the crosses 11 are given to each other.
  • the minimum distance the crosses 11 to each other is set such that a mutual influence of frequency selective Reflection properties of the crosses 11 is excluded. This results in circular crosses 11 Clearance areas 13.
