Abstract：In order to study the relationship between the morphological characteristics of cut tobacco and the filling density uniformity of slim cigarettes,the structural distribution(long-filament ratio,medium-filament ratio,short-filament ratio,etc.)and morphological parameters(length,width,curl)of cut tobacco were measured.The overall morphology of cut tobacco was characterized based on the above-mentioned values.A quantitative relationship model between the morphological characteristics of cut tobacco and the filling density uniformity coefficient of cigarettes was established using stepwise regression analysis.The optimal solution of the model was obtained to seek the best control direction of the cut tobacco structure,and production verification was carried out.The results showed that when the width of the reconstituted cut stems was 0.8～1.0 mm,it was in good conformity with the actual production,and the increase of the short and medium cut tobacco rate was conducive to improving the width conformity of the reconstituted cut stem.The significance of the multiple stepwise regression equation of the overall length,overall width,overall curl,medium cut rate,short cut rate and thin cigarette filling density uniformity coefficient index reached an extremely significant level(P＜0.01),when the proportion of reconstituted cut stems was between 2％and 8％,the linearity of the model was better.The cut tobacco structure was adjusted in production based on the optimal solution of the model,the overall length of the cut tobacco was reduced by 5.9％,the overall curl was reduced by 4.4％,the rate of medium and short tobacco threads increased by 57.9％,and the uniformity of cigarette filling density was improved by 45.5％.
