In particular, recently, as the demand for deodorizing cigarettes and the like has increased, its use for air purification has been increasing.
空気浄化の用途に使用する活性炭には、装置に組み込ま
れる関係から、■脱臭効果の高いこと、■圧力損失の小
さいことの２点が要求される。Activated carbon used for air purification is required to have the following two points because it is incorporated into equipment: (1) high deodorizing effect, and (2) low pressure loss.

すなわち、これらの内の粒状活性炭は、外表面積が小さ
く、また、細孔の径がまちまちであることから、吸着速
度が遅い欠点があった。That is, among these, granular activated carbon has a small outer surface area and has various pore diameters, so it has the disadvantage of slow adsorption rate.
また、空気浄化の用途に使用する場合は、粉状では飛散
して目的を達成し得ない。 そこで、かわりに、粉状活
性炭をポリウレタン多孔体に担持させたものが使用され
ているが、このような処理は、活性炭の本来の性能を損
なうため、その脱臭性能はいっそう劣ったものとなって
いる。 また、繊維状活性炭は、単位重量当りの吸着性
能は優れているが、粒状活性炭とは反対に、嵩密度の増
加が困難であり、かつ圧力損失が大きくなるため、厚く
できないという問題を有している。Furthermore, when used for air purification, powdered particles scatter and cannot achieve the purpose. Therefore, powdered activated carbon supported on a polyurethane porous material is used instead, but such treatment impairs the original performance of activated carbon, making its deodorizing performance even worse. There is. Furthermore, although fibrous activated carbon has excellent adsorption performance per unit weight, it has the problem that, contrary to granular activated carbon, it is difficult to increase the bulk density and it cannot be made thicker due to the large pressure loss. ing.
以上の点より、空気浄化の用途においては、圧力損失と
脱臭性能とのバランスの点でより性能の優れた材料が要
求されていた。From the above points, in air purification applications, there has been a demand for materials with better performance in terms of balance between pressure loss and deodorizing performance.
〈発明が解決しようとする課題〉
本発明は、上記のような従来技術に伴う問題点を解決し
ようとするものであって、空気浄化の用途に好適な圧力
