Abstract

969,683. Tobacco smoke filters. REEVES BROS. Inc. May 31, 1962 [June 2, 1961], No. 21038/62. Heading A2C. A rod-like tobacco smoke filter element comprises a plurality of fibres of thermoplastic material, each fibre having a ratio of perimeter to the square root of its crosssectional area greater than 3.54. Preferably the ratio is at least 10. The fibres are poly-alpha-olefine fibres, e.g. polypropylene fibres, are substantially free of crimping and molecularly unorientated, extend side by side, and are helically twisted with between “ to 2 turns per inch. The filter element may be provided with a wax stiffening coating on its outer periphery. Figs. 2 and 3 show the cross-sections of suitable fibres.
