Abstract
A bag house filtration system in which the filter media includes a woven textile formed from glass yarns other high temperature resistant yarns. A first bath is applied to the textile which contains a conductive component, a first fluoropolymer and a lubricant (in some cases where the yarns are glass). A second bath containing primarily a second fluoropolymer is then applied to the textile and the first composition to seal the first composition on the textile. The textile, so treated dissipates the static electricity normally generated in the filter media thus reducing excessive buildup of contaminating particles and enhancing cleaning of the bag during use.
