Abstract

PURPOSE: To reduce clogging and to improve collecting efficiency of matters to be filtered, by constituting a filter of single layer having continuous changes in bulk density gradient by using mixed fibers consisting of two kinds of fibers having different cross-sectional shapes, respectively.
CONSTITUTION: As a filter for gas or liquid, mixed fibers consisting of ≥2 kinds of special fibers having several cross-sectional shapes, a circular cross-sectional shape of regular type fiber or other special cross-sectional shapes such as Y-cross section, X-cross section, C-cross section, etc. are used. The filter is constituted of the single layer of fibers having a bulk-density gradient changing from 0.01W0.1 to 0.05W 0.4 continuously between the flow-in side and flow-out side of gas or liquid to be filtered. In this case, the clogging as a filter is reduced, and a filter of excellent filtering efficiency is obtained, by setting the bulk density gradient to the layer having a mild gradient at the flow-in side and a shape gradient at the flow-out side, respectively.
