、粉体を担持し易いものが好ましい。In the present invention, a sheet made of electret fiber
(Hereinafter, simply referred to as electret sheet) refers to a sheet made of paper, nonwoven fabric, cloth, etc. using electret fiber as a raw material, but it is preferable that the sheet surface is porous and can easily support powder.
ところで、エレクトレット繊維とは、帯電している繊維

レクトレットシートとして用いてもよい。By the way, electret fibers refer to electrically charged fibers, such as polymer resins that are stretched or semi-solidified and then solidified by applying an electric field to undergo intramolecular polarization. Therefore, an electret sheet made of such electret fibers also becomes electrically charged. Incidentally, a nonwoven fabric for an electret filter (EPA filter) made of a nonwoven fabric of electret fibers is commercially available, but a HEPA filter may also be used as the electret sheet of the present invention.

などの触媒等、主に気体と接触することにより各種機能
を発揮するものをいい、エレクトレットシートに静電吸
着担持され得る程度に微粉体のものをいう。Furthermore, in the present invention, monofunctional powders refer to those that exhibit various functions mainly when in contact with gas, such as gas adsorbents such as Cristobalite, Oya stone, and coral sand; catalysts such as ultrafine metal powders; Electret is a fine powder that can be electrostatically supported on an electret sheet.
このような機能性粉体をエレクトレットシートの一面あ

性及び緩衝性を付与することもできる。In order to support such functional powder on one or both sides of the electret sheet, it is sufficient to simply electrostatically adsorb it, but if the functional powder has insufficient supporting power, the powder may be further A thin breathable film may be electrostatically adsorbed onto the layer. Furthermore, if a breathable foamed heat insulating paper is used instead of this breathable thin film, it is possible to provide heat insulation and cushioning properties.

市販のエレクトレットフィルタ用不織布を大谷石粉末（
平均粒径２０μｍ程度）に接触させその両面に静電吸着
担持させた。Example: A commercially available nonwoven fabric for electret filters was mixed with Oya stone powder (
(average particle size of about 20 μm) and electrostatically adsorbed on both sides of the particles.
このようにして得た大谷石担持シートにエチレンガスを

量の流体を処理できるものである。Further, since the functional powder-carrying sheet of the present invention has flexibility, it can be used in any desired shape, for example, by stacking one sheet or a plurality of sheets into a roll. That is, it is possible to easily produce a functional powder-filled bed of any shape, and the filled layer has low air resistance (it can process a large amount of fluid).
