A Study of the Effects of Cigarette Materials on the Degree of Ventilation and Filtration Efficiency of the Cigarette with 24 mm Filter Rod

The orthogonal test, which dealt with different cigarette Paper, tipping paper, wrapping paper and filter, was designed and applied in situ. Test was to study the effects of the above factors on the degree of ventilation and filtration efficiency of the cigarette with 24 mm filter rod. The result indicates that the air permeability of tipping pa- per, wrapping paper, cigarette paper and the pressure drop of filter rod are the most prominent and important factors affecting the degree of ventilation and filtration efficiency. Therefore, the adjustment and control of these factors are the keystones of the cigarette quality control, which is one of the best ways to reduce the costs of the products. Compared with the other methods, this design of the experiment is shortcut, efficient, economical and veracious. By this method, the design and the techniques of the aimed product are optimized.
