The purpose of this invention is to provide a kind of new and effective radiation proof cloth that can overcome above technical performance shortcoming; has good radiation proof usefulness; reach the 30-45 decibel; have simultaneously following characteristics again: collapsible, wash resistant, good permeability, quality are light, outward appearance fashion, be convenient to processing; during cutting; also can guarantee the shielding property that it is good, can be made into the protection dress ornament on the protection whole body.

The present invention is achieved in that with conducting electricity very well, and is difficult for surface oxidation, and many or one soft of metal fine filament (diameter is between the 3-30 micron) are woven into metal fine.Counter-bending, the stretch-proof of above-mentioned metal fine and electric conductivity all strengthen greatly.Wire can have the coating that strengthens electric conductivity.Make woven wire again with above-mentioned metal fine.Per share metal fine spacing is between the 0.5-4 millimeter.Mesh can be circle or polygon, and the area of single mesh is between the 0.25-16 square millimeter.Make all longitude and latitude crosspoints be easy to direct contact, perhaps, its all longitude and latitude crosspoints have been interweaved and reliable contact when knitmesh.

On above-mentioned woven wire, on its grid with fiber knitted or crocheted, soft composite is filmed or injection moulding, cover paper material, forms soft clothes such as cloth shape, netted, paper shape.These materials on its grid have protection, increase the effect that resists folding and stretch-proof metal wire.Make the reliable firmly contact of each longitude and latitude intersection contact point of metal wire simultaneously by these processing methods.Also can be when weaving this cloth, the while shaping metal mesh.

Above-mentioned cloth can shield the electromagnetic wave of 10MHz-30GHz, can be by regulating wire netting mesh shape size, and the conductance of wire material can obtain the different screening frequencies scopes and the usefulness of shielding.Above-mentioned cloth can make electromagnetic wave attenuation 30-45 decibel, even higher, has the usefulness of better shielding than the former material of carrying.

Above-mentioned cloth is when processing is cut out; remove the above-mentioned fiber or the insulating materials such as soft composite or paper material at edge; can expose inner wire netting; with the reliable mutually contact of the wire head of two sheet material, can make whole clothes form faraday's catch net of a unified mutual conduction at seam crossing.Can design a metal hasp in the edge of clothes, different dress ornaments is interconnected with this metal hasp, can form the Faraday shield net that covers the human body whole body like this.Even can protect with Web materials of the present invention at people's face, can play the effect that does not influence sight line.Around the exposure suit of making like this, whole body is faraday's net of an integral body, and protection effect is good.
