Abstract
Hot gas filtration fabrics for bag filters can be made using fibers that include high silica fibers and at least one FR fiber. The fabrics can be made using these fibers by needling and/or water jet entanglement. The fabrics may be treated with binders with or without additives to enhance mechanical properties or to impart other characteristics such as gas adsorption. Certain non-woven fabrics made according to the invention have improved high temperatures filtration capabilities and mechanical properties.
