Abstract: A process for the preparation of a cellulose acetate film comprises the steps of: cooling a mixture of cellulose acetate and an organic solvent to -100 to -10 DEG C; warming the cooled mixture to 0 to 50 DEG C to dissolve the cellulose acetate in the organic solvent; casting the obtained solution on a support; and evaporating the organic solvent to form the cellulose acetate film. The cellulose acetate has an average acetic acid content in the range of 58.0 to 62.5%. The organic solvent is acetone.

Abstract: A tobacco smoke filter material comprises a fibrillated cellulose ester fiber with an average fiber diameter of 15 to 250 mu m and a BET specific surface area of 0.5 to 4.5 m /g. The fibrous cellulose ester content of the material may for example be not less than 20 weight %. The cellulose ester fiber is provided by, for example, extruding a cellulose ester solution from a nozzle (2) into a precipitating agent for the particular cellulose ester and subjecting the extrudate to a shear force. This filter material can be used in the form of, for example, a filament, web or sheet to provide a tobacco smoke filter which assures good smoking qualities and excellent wet disintegratability.

Abstract: To a constitutive element of a tobacco (a leaf-tobacco component or a filter) is added a proanthocyanidin or a proanthocyanidin-carrying porous material (such as an active carbon) to obtain an element for tobacco smoke. The proanthocyanidin may be at least one extract selected from a grape seed or pip, a grape rind or pericarp and squeezed dregs of a grape fruit.
