Abstract
A fabric having anti-static properties being formed from a first woven layer of polymeric fabric, a second woven layer of polymeric fabric which contains spaced threads of staple metal fibres and an intermediate layer positioned between the first and second layers to form a moisture barrier. In its most preferred form the woven polymeric fabric is formed of woven polypropylene and the spaced threads of staple metal fibres are formed of staple stainless steel fibres carried on a central core of a synthetic material. The fabric is of particular use in the manufacture of intermediate bulk containers where it is believed is advantageous in permitting corona discharge at a very low voltage of static electricity thereby preventing any dangerous build-up of voltage which subsequently is discharged by a spark.
