Fabric for shielding electromagnetic waves from e.g. telecommunication system, has composite wires intersecting to form mesh, where each composite wire includes two textile wires mounted around conducting core in twisted manner

摘要

The fabric has composite wires (2) extending parallel to a plane of a fabric and intersecting to form a mesh. Each composite wire includes two textile wires (24, 26) mounted around a conducting core (22) in a twisted manner, where one textile wire is symmetrical from the other with respect to a plane containing the conducting core. Each textile wire has a diameter lower than 0.1 mm, where the number of revolutions of each wire around the conducting core is between 100 and 400 turns per meter so as to cover 80 percent of a surface of the conducting core.
