It is known that reconstituted tobacco leaf tends to generate dust and particles during the cutting process in the cigarette factory. To solve the issue, analysis of the composition structure of manufacturing waste was carried out. Effects on the fragmentation rate of reconstituted tobacco base sheet were studied with the following factors: 1) beating degree; 2) use of additives in the pulping process; and 3) use of calcium carbonate. The analysis showed that the composition of the manufacturing waste included detached fibers from the edge of reconstituted tobacco, ash from the raw tobacco materials, particles and powder produced by the tobacco pellets, calcium carbonate, and a small quantity of short and small fibers lost during the beating of tobacco stem and wood pulp. There is a negative correlation between the fragmentation rate of reconstituted tobacco base sheet and the beating degree. When the beating degree increases, the fragmentation rate during cutting decreases. The use of guar gum in the pulping process can effectively reduce the fragmentation rate. In conclusion, this study provides potential solutions for reducing the impact of the stated problem, and improving the efficiency of utilizing paper-making reconstituted tobacco.
