A process for producing a fabric absorbent that is capable of efficient removal of odorous substances, in particular malodorous substances. The absorbent is obtained by exposing an organic high-molecular weight compound, such as polyolefinic polymers or halogenated polyolefinic polymers, to an ionizing radiation and thereafter graft polymerizing the high-molecular weight compound with a polymerizable monomer that contains ion-exchange groups and/or a polymerizable monomer that can be converted to ion-exchange groups so as to incorporate the ion-exchange groups in the high-molecular weight compound.

[ What is claimed is:] [37.] A method for removing fine particles and polar gaseous substances from a gaseous atmosphere, comprising:passing the gaseous atmosphere through an adsorbent fabric made by the steps ofexposing to an ionizing radiation a woven or nonwoven fabric made from a material comprising a polyolefin; and thengraft polymerizing onto the exposed polyolefin, one or more polymerizable monomers selected from the group consisting polymerizable monomers having ion exchange groups and polymerizable monomers that can be converted to ion exchange groups; andwhen said polymerizable monomers include ones that can be converted to ion exchange groups, converting said polymerizable monomers to ion exchange groups,wherein said craft polymerizing step and, if necessary, said converting step take place under conditions such that the resultant product is capable of removing fine particles and polar gaseous substances from a gaseous atmosphere by passing the gaseous atmosphere through the adsorbent fabric.
