摘要： A filter material fabricated by mixing 10 to 30% by mass of first fibers having a fiber diameter of 10 to 40 µm, 40 to 80% by mass of second fibers obtained by crimping natural fibers having a fiber diameter of 10 to 40 µm, and 10 to 30% by mass of third fibers having a fiber diameter of 5 to 10 µm. The filter material has low pressure loss, a high dust holding amount, and high dust filtration efficiency.

摘要： The present invention relates to a producing method of a laminated filter that carries out a corrugating operation and an adhering operation of filter media in the same step. A corrugation forming apparatus (20) sandwiches first and second filter media (12, 14) in their superposed state, and heats and presses the first and second filter media (12, 14) at the softening temperature of the second filter medium (14) to corrugate the filter media (12, 14), and thermally adheres the first and second filter media (12, 14) to each other. With this, it is possible to carry out the corrugating operation and the adhering operation of the first and second filter media (12, 14) in the same step.
