ABSTRACT:
A fabric filter bag, a method of making such a bag, and apparatus using such bags, in which the bag is a tube of yarn knit into stitches defining a ground and stitches defining terry loop pile extending from the ground. In accordance with the present invention, such a fabric filter bag, method of making a bag, and apparatus using a bag is improved by the inclusion of a conductive strand for conducting electrostatic charges otherwise accumulating on the fabric filter bag away from the bag so as to suppress accumulation or build-up of such charges.
