Abstract

A tobacco smoke filter comprises synthetic filaments, activated carbon particles and a high molecular weight (i.e. between 600 and 20,000) polyalkalene glycol. Preferably the polyalkalene glycol is a polyethylene glycol, a methoxy polyethylene glycol, or a propylene glycol. The activated carbon particles have a mesh size (U.S. Standard) of 10-325, preferably 10-45, and the filter may contain from 2 to 200 parts by weight of carbon particles and from 2 to 25 parts by weight of glycol per 100 parts by weight of filaments. Suitable synthetic fibres are cellulose acetate tow or yarn having a total dernier of 25,000-75,000 and a dernier per filament of 1-16. Flavourants may be included in the filter. The filters, which may be used in series with conventional filters, may be prepared by spreading the fibres and coating them, e.g. by spraying, with the polyalkalene glycol, after which the carbon particles are applied to the coated fibres. Before the glycol has solidified the fibres are formed into a rod. Quantitative examples are given.
