Abstract
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.
