HOT GAS FILTRATION FABRICS WITH SILICA AND FLAME RESISTANT FIBERS

摘要

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 mad e 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. Certai n non- woven fabrics made according to the invention have improved high temp eratures filtration capabilities and mechanical properties.
