Abstract

PURPOSE: To provide the filter medium for air cleaner excellent in dust-retaining capacity and cleaning efficiency by a method wherein three fiber layers, i.e. upper, middle and lower fiber layers having specified fiber sizes and amounts respectively are laminated, the fibers of the different layers are entangled with each other and a resin adhesive is applied to the laminate to unite the layers.
CONSTITUTION: The upper fiber layer consisting of a mixture of 30W40g/m2 of polyester staple fibers of 4W15 denier and 30W40g/m2 of polyester staple fibers of 1W4 denier, the middle fiber layer 2 consisting of 40W60g/m2 of polyester staple fibers of 1W6 denier, and the lower fiber layer 3 consisting of a spun bonded sheet of thermoplastic synthetic filaments with the filaments partly fused to each other are laminated and the layers 1W3 are punched by needles 4 to form entangled parts (a) among the fibers of the layers. Then, the resin adhesive is applied to the integrated sheet-form material in an amount of 40W60g/m2 to unite the layers, obtaining the filter medium.
