Abstract

PURPOSE:To obtain a filter capable of controlling clogging due to the deposition of dust by fixing a water repellent with a density distribution reverse to the fiber density distribution in the filter wherein the fiber density is continuously changed in the thickness direction. CONSTITUTION:The fiber density of the filter member in the thickness direction is decreased on the gas inlet side, and increased on the gas outlet side. The water repellent is fixed to the member with a density distribution reverse to the fiber density distribution. When the filter member is produced, the water repellent is firstly sprayed on one side in the thickness direction of a web, and sucked from the opposite side of the web to impregnate the web with the repellent. The material is then heated to fix the water repellent to the web. The web is then impregnated with the binder of water-based emulsion type, and hot-pressed to produce the filter member.
