International ClassesB32B 009/00G21F 003/02 AbstractAn electromagnetic shielding fabric is formed entirely from a plurality of synthetic fiber yarns which have been previously coated with silver. The preferred yarn structure comprises silver-coated nylon yarns, although other synthetic yarns can also be used as a base for the silver-coated yarns. The silver content of the silver-coated synthetic yarn is preferably not less than 20% by weight, and the conductivity of the silver-coated yarn is preferably not less than 1.2 ohms/cm. The silver-coated synthetic yarns are preferably formed into a planar textile material by means of a warp-knitting method which interlocks all of the yarns in a continuous chain stitch. The resulting fabric is thus formed entirely of the conductive silver-coated yarns thereby providing superior conductivity and electromagnetic shielding capability.Field of SearchCOATED OR STRUCTUALLY DEFINED FLAKE, PARTICLE, CELL, STRAND, STRAND PORTION, ROD, FILAMENT, MACROSCOPIC FIBER OR MASS THEREOFWith coating or impregnation Bicomponent, conjugate, composite or collateral fibers or filaments (i.e., coextruded sheath-core or side-by-side type) Coated or with bond, impregnation or core Free metal in coating Radiation reflective Radiation absorptive | |
