せるようにしたものである。[Means for Solving the Problems] In order to achieve the above object, in the method for producing a filter of the present invention, in the surface of a molding substrate provided with a silicifying agent layer, a synthetic resin-based adhesive containing a foaming agent is added. Apply the agent uniformly with a roll coater, flow coater, etc. to form a filter substrate, implant a large number of short fiber groups on the surface, and then dry at 80 ° C to 150 ° C for 5 to 10 minutes. In this way, the filter substrate is foamed to form a filter main plate, and then the filter main plate is peeled off from the molded substrate.

In FIGS. 1 and 2, reference numeral 1 is a filter main plate having an open cell layer formed of a synthetic resin adhesive, and a large number of short plates are formed on the surface thereof. The fiber group 2 is planted. 3 to 5 show the manufacturing process of the filter, in which a synthetic resin adhesive (urethane-based, epoxy-based adhesive) containing a foaming agent is added to the surface of the molded substrate 3 provided with the silicidizing agent layer. Vinyl-based) is uniformly applied by a roll coater, a flow coater, etc. to form the filter substrate 1a, and a large number of short fiber groups 2 (fiber thickness is about 10 denier is formed on the surface of the filter substrate 1a by electrostatic flocking. , The length is about 2 mm is suitable), then pre-dry for about 5 minutes at 80 ° C-90 ° C with a dryer, then at 100 ° C-150 ° C for 5 minutes. ~Ten
By performing main drying for a minute, the filter substrate 1a is foamed to form the filter main plate 1 having an open cell layer.
しかる後成形基板３からフィルター主板１を剥離させる
ことによりフィルターは完成する。Then, the filter main plate 1 is separated from the molded substrate 3 to complete the filter.
