1. A flexible electromagnetic shielding fabric comprising a plurality of synthetic yarns which have been previously coated with a continuous exterior silver coating wherein the silver content of the silver-coated synthetic yarn is not less than 20% by weight, and the conductivity of the silver-coated yarn is not less than 1.2 ohms/cm, said plurality of silver-coated synthetic yarns being formed into said fabric by means of a textile fabrication method such that the fabric is comprised substantially entirely of said silver coated synthetic yarns, said silver-coated synthetic yarns of said fabric being individually freely slidably movable relative to adjacent yarns within the fabric to provide flexibility, said exterior silver coating of each of said silver-coated synthetic yarns being in sliding electrical contact with the exterior coating of adjacent silver-coated synthetic yarns to provide continuous, omni-directional conductivity from yarn to yarn throughout the entire fabric.
