Abstract: An anti-static fleece or brushed fabric consisting essentially of acrylic fiber, polyester fiber, cotton fiber, wool fiber, nylon fiber or combinations of 2 or more thereof, characterized in that the fleece or brushed fabric has a basis weight of from 65 gsm to 400 gsm, contains from 0.1 wt % to 2 wt % of bicomponent anti-static fiber and is further characterized in that the fleece or brushed fabric exhibits a static decay time of less than 4 seconds The woven or knit fleece or brushed fabric has permanent anti-static properties which do not wash out during laundering. A preferred yarn for making the fleece or brushed fabric is a composite anti-static filamentary yarn comprising anti-static bicomponent filament wrapped with non-conductive filament in a weight ratio of non-conductive filament:anti-static bicomponent filament of from 2:1 to 8:1.
