ABSTRACT:
Water disintegratability of a tobacco filter is improved by incorporating a super absorbent resin into a tobacco smoke filter medium in a tobacco filter comprising a main constitutive element of the tobacco smoke filter medium, and a water-soluble polymer as a binder for shaping the constitutive element. The constitutive element includes particulate or fibrous cellulose and cellulose esters (e.g. cellulose acetate). The water-absorption ratio of the super absorbent resin is about 10 to 1,000 times, and the amount of the resin is about 0.05 to 50 parts by weight relative to 100 parts by weight of the main constitutive element of the tobacco smoke filter medium.
