Abstract

A method of producing a tobacco-smoke filter comprises treating filamentary or sheet tobacco smoke filter material with a polyalkylene imine, preferably polythylene imine. The imine may be applied to the material in the form of an aqueous solution by spraying or soaking. The amount of imine applied is from 5% to 50% by weight of the filter material. Quantative examples are given.
