A sheetlike environment purifying material comprising (a) particles of a metal and/or a metal oxide, (b) particles of an absorbent, (c) particles of a thermoplastic resin and (d) an air-permeable fibrous base sheet, wherein the particles (a) and (b) are bonded to the surfaces of the particles (c) via the contacts of particles with each other and the particles (c) are bonded to the base sheet (d). This material can be produced by mixing the particles (a), (b) and (c), a water-absorbing resin (e) and water together to form a homogeneous suspension, making a predetermined amount of this suspension held on the fibrous base sheet (d), and heating the resulting composite in a temperature range from the melting point of the resin of the particles (c) to the thermal decomposition temperature thereof to bond the particles to the fibrous base sheet (d) via the particles (c) through the removal of water. The particles of a metal and/or a metal oxide and the particles of an adsorbent are not covered with any thermoplastic resin layer and therefore retain their respective original surface areas and performances to exhibit an excellent environment purifying power. This material is useful as deodorizer, toxic gas remover, and the like. |
