Embodiment 1
[0023] Weigh a certain amount of chitosan with a particle size less than or equal to 80 meshes, add it to the triacetin in a proportion of 7% by weight of the triacetin, and stir at a high speed to make it evenly dispersed in the triacetin to form a dispersion for later use . During the forming process of the filter rod, the chitosan / triacetin dispersion was used as a plasticizer and adhered to the surface of the acetate tow in a proportion of 8% by weight of the acetate tow. In this process, chitosan is carried by triacetin and evenly scattered on the acetate fiber tow to make a chitosan-loaded cigarette filter rod, numbered as test filter rod 1#.
Embodiment 2
[0025] A certain amount of nano-chitosan was weighed, added to triacetin in a proportion of 7% by weight of triacetin, and stirred at a high speed to make it evenly dispersed in triacetin to form a dispersion for later use. During the forming process of the filter rod, the nano-chitosan / triacetin dispersion was used as a plasticizer to adhere to the surface of the acetate fiber tow in a proportion of 8% by weight of the acetate fiber tow. In this process, nano-chitosan is carried by triacetin and evenly scattered on the cellulose acetate tow to make nano-chitosan-loaded cigarette filter rods, numbered as test filter rod 2#.
Embodiment 3
[0027] A certain amount of nano-chitosan was weighed, added to triacetin in a proportion of 3.5% of the weight of triacetin, and stirred at a high speed to make it evenly dispersed in triacetin to form a dispersion for use. During the forming process of the filter rod, the nano-chitosan / triacetin dispersion was used as a plasticizer to adhere to the surface of the acetate fiber tow in a proportion of 8% by weight of the acetate fiber tow. In this process, nano-chitosan is carried by triacetin and evenly scattered on the acetate fiber bundles to make nano-chitosan-loaded cigarette filter rods, numbered as test filter rod 3#.
