PROBLEM TO BE SOLVED: To provide a bag filter medium capable of improving collection efficiency for dust within dust and exhaust gas, and having a large dust collecting capacity and a long service life as a result of withstanding dust sweeping off of the bag filter media, that is, expansion and contraction of the filter media.SOLUTION: An ultrafine fiber having a fiber diameter of 0.01 to 0.5 μm is laminated on or mixed with non-woven or woven cloth made of synthetic fiber or glass fiber or natural fiber, etc., and a filter medium in which an ultrafine fiber is formed integrally with non-woven or woven fabric is folded cylindrically or in a zigzag pattern to be pleated so that the circular or envelop-formed bag filter medium can be obtained for regeneration by sweeping off. |
