Abstract: In order to comprehensively evaluate the ash integration and cohesion of statically burning i.e., smoldering cigarettes based on cigarette paper parameters, the correlations between cigarette paper parameters and cigarette ash integration indexes were investigated with RSD, simple correlation and multiple linear regression analyses. The results showed that: 1) For the degree of comprehensive influence on ash integration, the order of cigarette paper parameters was ash crack rate > burn line width > ash color > ash shrink rate > burn line uniformity. 2) According to the significance degrees, the weights of cigarette paper parameters were determined and a comprehensive ash integration evaluation index was proposed. 3) The regression equation between the proposed index and the cigarette paper parameters was established, and the calculated value of the regression equation agreed well with the actual measured value(R² =0.851). 4)For the proposed comprehensive evaluation index, the degree of influence was ash content > grammage > burn additive content > potassium proportion in burn additive > air permeability. The ash integration improved with the increase of ash content and grammage, while it deteriorated with the increase of air permeability, burn additive content and potassium proportion in the burn additive. This comprehensive evaluation provided technical insights to promote ash integration and cohesion of smoldering cigarettes.
