Zusammenfassung:	An 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.
