摘要： The cartridge filter of the present invention is a filter comprising a wound and laminated composite non-woven fabric containing heat fusible fibers, wherein the delamination strength between layers of the laminated composite non-woven fabric of said filter increases continuously or discontinuously from the outer layer toward the inner layer, the delamination strength of the inner layer-exceeds 1000 gf/5 cm, and the delamination strength of the outer layer is 5 to 1000 gf/5 cm. This cartridge excels in filtering life, filtering accuracy, and pressure resistance.
