Tobacco manufacturing process

Cigarettes were prepared by wrapping tobacco using general cigarette paper and tobacco fiber cigarette paper. All cigarettes and herb blends, except for general cigarette papers and tobacco fiber cigarette papers, were used in the manufacture of cigarettes. Table 1 shows the physicochemical characteristics and chemical composition of general cigarette paper and tobacco fiber cigarette paper.

LOD means the limit of detection.

Zeta potential measurement

Zeta potential was measured for normal cigarette paper and tobacco fiber cigarette paper 1 and shown in FIG. 4.

General cigarette paper and tobacco fiber cigarette paper 1 was mixed with distilled water at 25 ℃ and dissociated to form a paper material of 1.5% ~ 2.0%. The prepared stock was put into the cell of the zeta potential measuring equipment, and a constant pulse vacuum was applied to the stock. The stock put into the measuring cell is separated into water and fiber pads by vacuum, and the solution separated from the fibers by vacuum forms a streaming current. The difference in the potentials occurring in the flow stream was measured, and the zeta potential of the fiber was calculated by the Smoluchowski equation.

It can be seen that the tobacco fiber cigarette paper has a lower zeta potential than the general cigarette paper.

Where ΔU: Streaming potential, ΔP: Pressure difference, η: Viscosity, L / Q: Cell constant, ε, εo: Dielectric constant, R: Electric resistance

Weight average length measurement

The weight average length of the general cigarette paper and the tobacco fiber cigarette paper 1 was measured and shown in FIG. 5.

It can be seen that the tobacco fiber cigarette paper has a weight average length longer than that of the general cigarette paper, which may be influenced by tobacco fibers in a bulky and patch form.

Pyrolysis Characterization

Pyrolysis characteristics of tobacco fiber cigarette paper 1 and general cigarette paper were measured and shown in FIGS. 6A and 6B, respectively. Herein, the tobacco fiber cigarette paper contained all three dyes described above.

As a result of the thermal decomposition pattern analysis of the general cigarette paper and the tobacco fiber cigarette paper, it can be seen that the thermal decomposition pattern is similar except that the nicotine component is detected in the tobacco fiber cigarette paper. Since the above three dyes are FDA food use substances, it can be seen that the safety of tobacco fiber cigarette paper is ensured.
