Definitions

  • the technical field of the present invention is that protective fabrics against radiation electromagnetic.
  • Another solution is to use coatings conductors that are applied to a support so as to make a conductive wall.
  • Another solution is to use a soft fabric or a composite material containing in its thickness conductors.
  • the object of the present invention is to provide a fabric flexible to easily protect equipment allowing to attenuate low frequency magnetic fields.
  • the subject of the invention is therefore an electromagnetic tissue consisting of at least two walls interconnected by son, characterized in that it includes lead wires woven with the walls and connecting said walls for attenuate the low frequency magnetic fields.
  • the density of conductive wires is chosen to favor attenuation of electric and electromagnetic fields.
  • the conductor is of a metallic or metalloplastic nature.
  • the fabric comprises three walls, two outer walls and one inner wall interposed between them, the wires conductors interconnecting the three walls.
  • the walls are spaced apart from each other by about 2 to 5 mm.
  • the wires are made of copper or stainless steel and are treated with varnishing or tinning.
  • the invention also relates to a method of weaving a fabric comprising a plurality of walls, characterized in that to make it electromagnetic we weave all with lead wires.
  • the fabric according to the invention can be produced in three layers as shown in section in FIG. weaving is strictly identical, but this variant of realization helps increase insulation performance electromagnetic tissue. These performances can be increased again by making a multi-wall fabric.
  • the conductive wire used according to the invention can be of different nature. We can of course use a wire entirely metallic. This thread is planned sufficiently late to be woven with natural or synthetic yarns used. In this case it is a drawn wire. It is also possible to use a metal-plastic wire. In this case, this wire is made from metal filaments inserted among the plastic or natural fibers or made from plastic or natural threads wrapped with line (continuous circular filament) or blade (continuous filament flattened circular). The wrapping can have a few steps tenths of a mm to several mm.
  • the metallic material itself constituting the wires is a good conductor of electricity, such as stainless steel, steel or copper.
  • Surface treatments can be applied on these threads such as tinning or varnishing so to improve, for example, the attenuation properties electromagnetic by adding tin for tinning and anti-corrosion properties for varnishing.
  • the invention therefore provides a means of protection quite powerful to protect a material without having to build a specific structure rigid and difficult to move. So we can protect the material in question whatever the place of its establishment and this very quickly.
