Synergetic Performance of Retention Aids on Reconstituted Tobacco by Papermaking Process

Abstract:

In this work, the effects of four kinds of additives including polyethyleneimine, carboxymethylcellulose, guar gum, and chitosan on the retention performance of reconstituted tobacco pulp and strength character of final base sheet were discussed. The results showed that the filler retention efficiency and first pass retention efficiency increased by 17.7% and by 5.8% at chitosan dosage of 0.2%, respectively. Moreover, the tensile index showed a distinct increase in chitosan retention system. The largest strength index was found to be in carboxymethylcellulose retention system, the tensile index was increased from 6.5 N•m/g to 8.67 N•m/g, and the wet tensile index was increased from 0.37 N•m/g to 0.51 N•m/g.
