This fiber material is a fiber laminate made by overlapping and integrating one or more webs mainly made of ultrafine combustible synthetic fibers with a single fiber diameter of 0°1 to 1.5 μm. This furnace material is flammable and can be disposed of by incineration after use.

。逆に、孔径の大きい濾材を使用すると、空気中の有害
物質を十分に濾過できない欠点が生ずる。Therefore, in order to sufficiently remove these harmful substances, a filter medium with a small pore size must be used. However, if the pore diameter is small, the furnace material will become clogged after a short period of use, so there is a drawback that the furnace material must be replaced after a short period of time. On the other hand, when a filter medium with a large pore size is used, there is a disadvantage that harmful substances in the air cannot be sufficiently filtered.
この発明は上記の欠点を解消して、空気中の有害物質を
十分に除去することができると同時に。This invention solves the above-mentioned drawbacks and can at the same time sufficiently remove harmful substances from the air.
通気抵抗の低い炉材を提供することを目的とする。The purpose is to provide a furnace material with low ventilation resistance.

16-22% of glass fiber is preferred. These glass fibers are alkali glass fibers or non-alkali glass fibers 1 selected, for example, from glass fibers having an average diameter of about 1.5μ and glass fibers having an average diameter of about 2.5μ on a weight basis. It is characterized by being extremely thin. Glass fibers reduce air pressure loss across the filter. In this way, the glass fibers form dense pores in the 7P material and collect relatively small floating particles. By incorporating glass fiber, the area of contact with harmful substances in the air can be increased by about 40 times compared to the volume of the furnace material.
