Abstract:
     Based on aerodynamic principle, a porous membrane is arranged in tip filter of acetate fibre for cigarette. On smoking, smoke flow moves in the form of eddy current, resulting in that strong carcinogenic substances such as tar oil is repeatedly adsorbed and held by the acetate fibre column of tip filter. Tests prove that the tar oil is reduced by about 50%.
