Abstract:
1. A fabric sleeve for protecting elongate members against at least one of EMI, RFI or ESD, comprising: at least one hybrid yarn filament having a non-conductive filament and at least one continuous conductive wire filament overlying an outer surface of said non-conductive filament and extending radially outward from an adjacent portion of said outer surface; wherein said wire filament is interlaced in electrical communication with itself or with other ones of said wire filaments along a portion of said sleeve to provide protection to the elongate members against at least one of EMI, RFI or ESD; wherein a plurality of yarn filaments extend along a warp direction corresponding to a length of the sleeve, at least some of said warp direction yarn filaments being provided as said at least one hybrid yarn filament and a plurality of yarn filaments extend along a fill direction generally perpendicular to said warp direction, at least some of said fill direction yarn filaments being provided as said at least one hybrid yarn filament, said wire filaments overlying said warp direction non-conductive filaments are in electrical communication with said wire filaments overlying said fill direction non-conductive filaments; and wherein said at least some of said warp direction yarn filaments or said at least some of said fill direction yarn filaments have at least two of said continuous conductive wire filaments and the other of said at least some of said warp direction yarn filaments or said at least some of said fill direction yarn filaments have a single one of said continuous conductive wire filaments.
