摘要： An RFI/EMI shielding material composed of a conductive multi-fiber having a plurality of metalized monofilaments, each monofilament including a composite core of copper clad stainless steel or low carbon steel reduced to an intermediate diameter, and at least one layer of metal or metal alloy electroplated on the clad copper of the composite core, where each of the monofilaments is drawn after electroplating to a final diameter less than the intermediate diameter, in the range of about 45-78 μm.

摘要： A yarn or multi-fiber formed of a plurality of micron diameter stainless steel monofilaments which have been rendered more conductive by one or more coatings of electrolytically-deposited metal or metal alloy materials. The metallized yarn provided by the invention has a very low electrical resistance, with consequent benefit in electrical performance, and is particularly useful as an RFI/EMI shielding material.
