Application of Cationic Modified Fibers in Heat-not-burn Reconstituted Tobacco by Papermaking Composite Method
In this study,cationic modified fibers with positive charge and higher water retention value were used to prepare heat-not-burn re-constituted tobacco sheet substrate,by composite papermaking with bleached wood pulp to improve the absorption performance of the sub-strate.The results showed that the dosage of cationic modified fibers could effectively reduce the tightness of the substrate,improve its ab-sorption performance to the coating solution,and increase the loading ratio of the heat-not-burn reconstituted tobacco to the coating solution.The coating loading ratio of heat-not-burn reconstituted tobacco was 121.69%without cationic modified fiber.Howere,the coating loading ratio of heat-not-burn reconstituted tobacco could reached 215.58%with the doasge of cationic modified fiber was 100%,which increased 93.89 percentage points.The cationic modified fiber was selected to prepare the tobacco sheet substrate with the dosage of 60%.The sub-strate's tightness was 0.45 g/cm3,the porosity was 70.90%,and the air permeability was 17.92 µm/(Pa·s).The loading rate of the prepared heat-not-burn reconstituted tobacco to the coating solution was 154.67%,and the heat-not-burn reconstituted tobacco had good taste.
