Effects of cigarette paper parameters on combustion coal fallout propensity of burning slim cigarettes.

In order to investigate the effects of cigarette paper properties on the combustion coal fallout propensity of burning slim cigarette, cigarette paper with different parameters ( grammage, air permeability, hemp pulp content, ash content, burn promoter content and proportion of potassium salts in burn promoter) was selected and the samples of fine cigarette were made. The parameters were set optimization. The results showed that the combustion coal fallout propensity of slim cigarettes decreased rapidly with the increase of paper grammage. The presence of air permeability, hemp pulp content and ash content in cigarette papers was able to promote the fallout propensity of combustion coal, in a content-dependent manner. Meanwhile, air permeability of cigarette paper exhibited a positive correlation to the combustion coal fallout propensity. The change of burn promoter content had no significant effect on reducing the tendency of the fallout propensity of combustion coal, while the excessively high proportion of potassium salts in burn promoter would cause the tendency of the fallout propensity of combustion coal to fall rapidly. The four parameters of air permeability, grammage, burn promoter content and proportion of potassium salts in burn promoter were sorted in descending order of the influence on the combustion coal fallout propensity as below: air permeability > grammage > proportion of potassium salts in burn promoter > burn promoter content. The combustion coal fallout propensity decreased from6. 3% to 2.5% with the optimum cigarette paper parameters of air permeability 50 CU, grammage 34 ⋅ m-2, proportion of potassium salts in burn promoter 50%, burn promoter content 1.5%.
