In recent years, much research has been conducted at home and abroad on the improvement of cigarette ash wrapping performance by adjusting cigarette paper parameters and the influence of different tobacco shred formulas on combustion. For example, the carbon fiber cigarette paper for improving the ash wrapping property invented by the Modi company, namely, the carbon fiber which accounts for 60 percent of the total amount of the fiber and has the average length of less than 1.91cm is added into the cigarette paper, so that the ash wrapping capability of the cigarette paper can be obviously improved. The cigarette paper for inhibiting the dispersion of the cigarette ash developed by Nicotiana japonica company can obviously inhibit the splitting of the cigarette ash without increasing the total amount of the auxiliary agent. The research on the factors influencing the ash wrapping capacity of the cigarette paper by the cigarette in Hubei shows that the cigarette paper has increased air permeability, quantitatively increased air permeability, reduced citrate combustion improver content and properly increased proportion of reconstituted tobacco leaves, the ash wrapping capacity of the cigarette paper is enhanced, and the ash wrapping capacity of the cigarette paper is enhanced.

In the aspect of influence of a tobacco shred formula and a tobacco shred structure on the falling of a combustion cone, research is carried out by changing the sizes of cut stems, reconstituted tobacco shreds and cut leaves in the tobacco shred formula, and the influence factors of the tobacco shred structure on the falling rate of the cigarette combustion cone are found to be the reconstituted tobacco shred ratio, the filament ratio, the medium shred ratio and the cut stem ratio, and the ash wrapping phenomenon of the cigarette can be effectively improved by reducing the filament ratio and improving the medium and short shred ratio.
