ABSTRACT:
A filter cartridge formed by winding, in a twill construction, a band-shaped unwoven cloth, which contains thermoplastic fibers and at least a part of its fiber intersections are stuck thereon, so that a cylindrical shape can be obtained, wherein 1. two types of filtrating layers are used, 2. unwoven cloth having opening hole parts is used, 3. an end face seal part is provided on both end parts of the cartridge, 4. unwoven cloth having a tongue piece part is used, or 5. two or more pieced of unwoven cloth are wound simultaneously, whereby those characteristic of the filter cartridge such as liquid permeability, filterable life, and stability of filtration accuracy can be kept in balance with each other.
