Effects of Different External Fibers on the Quality of Tobacco Composite Filter Rod Paper
In order to improve the performance of tobacco-based filter rod paper,six kinds of external fibers,namely bleached softwood pulp,bamboo pulp fibers,hemp pulp,cotton pulp,fluff pulp,and unbleached softwood pulp were mixed with tobacco stem pulp.Considering that the external fibers have different fiber characteristics,the effect of the beating de-gree and the substitution ratio of external fibers on the physical index of tobacco filter rod paper was studied in our present research.The results showed that the strength and elongation of tobacco-based filter rod paper were improved with the in-creased substitution ratio of external fiber.Among them,the performance of the tobacco-based filter rod paper mixed with hemp pulp was better than the other five kinds of external fibers.When the beating degree of hemp pulp was 50 °SR and the substitution ratio of hemp pulp was 90%,the tensile index of tobacco filter bar paper was 76.3 N·m/g,and the elongation was 3.10%.Therefore,this study has laid a theoretical foundation for the development of tobacco-based filter rod paper.
