| Abstract:Low ignition propensity (LIP) cigarette can reduce the risk of fire ignited by cigarette. In order to apply LIP paper to flue-cured tobacco cigarette, base paper porosity, content of burning agent and diffusion rate of retardant belt were optimized. Then optimized paper was applied to flue-cured tobacco cigarette. The ignition performance, free air self extinguish and content of CO, tar and nicotine in new LIP cigarette were determined, besides, smoking quality was evaluated. The result showed that: (1) after optimization, base paper porosity was 95 CU, content of burning agent was 1.0% with diffusion rate of retardant belt for 0.115 cm/s;（2）The ignition performance and free air self extinguish test of LIP cigarette met the requirement of ASTM E2187-04. Content of CO, tar and nicotine in mainstream smoke of LIP cigarette had no change. There was no significant difference in smoking quality between ordinary and LIP cigarette. |
