Effect of wood pulp fiber and filler on the mechanical properties and harmful substance of reconstituted tobacco sheet were investigated. Experiments result showed that added lower lignin content pulp reduced phenols produced by reconstituted tobacco sheet combustion. As addition of bleached hardwood kraft pulp and precipitated calcium carbonate (PCC) increased, the amount of phenols release was dropped dramatically, but in order to ensure the normal operation of papermaking mechine, wood pulp and PCC addition should not be more than 20%. If wood pulp addition was above 20%, it had negative effect on the bulk, carbon monoxide and cigarette smoke flavor of reconstituted tobacco sheet; when PCC addition was more than 20%, it has negative effect on the normal operation of papermaking mechine.

The application of talcum powder (TP) as filler in the production of base sheet of paper-process reconstituted tobacco were studied both by laboratory scale experiment and pilot scale trial. The results showed that using TP as filler of the base sheet obviously improved the ash content and liquid absorption characteristic of the base sheet compared with using precipitated calcium carbonate (PCC). Meanwhile, the smoking qualities of the base sheets were evaluated by the tobacco experts and the final evaluation results showed that the base sheet with TP had better smoking quality.

The glyoxalted polyacrylamide(GPAM) resins were obtained by cross-linking reaction between glyoxal and cationic polyacrylamide(CPAM) through aqueous solution copolymerization. The based CPAM was synthesized with acrylamide(AM) and diallyl dimethyl ammonium chloride(DADMAC) as raw materials by living free radical solution polymerization. Various synthesis conditions were discussed and the optimum conditions for copolymer’s synthesis were as follows: the amount of DADMAC 20%(wt), the charge of the initiator 0.5%(wt), the dosage of chain transfer agent(2-mercaptoethanol) 1.0%(wt), and the charge of crosslinking monomer 9.0%, the dosage of glyoxal 25%(wt), the pH value of the tertiary reaction 7.5-8.0 and the tertiary temperature about 65°C. The structure of the resulting product was characterized by FT-IR, 1H-NMR. Then the GPAM resins were used in the process of paper-making as wet-end additive, the results showed that the paper sheets can get a significant increase in strength properties from the added novel product.
