Problems solved by technology

However, in this patent, chitosan only exists in the center of the filter rod, and the contact area with the flue gas is small, and the harm reduction function of chitosan cannot be fully exerted, so the harm reduction effect is limited
Moreover, the processing technology of the chitosan adsorption line is relatively complicated, and it is difficult to realize industrial production

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#.

Abstract

The invention discloses a cigarette filter rod loaded with nano chitosan. The cigarette filter rod is characterized in that the cigarette filter rod can effectively reduce the content of lead, cadmium, nickel, arsenic, chromium, selenium and other heavy metal in the smoke of a cigarette, and the reducing effect on the three kinds of heavy metal of the lead, the nickel and the selenium is especially obvious. A preparation method of the cigarette filter rod loaded with the nano chitosan is characterized in that firstly, the nano chitosan is scattered into filter rod plasticizer glycerol triacetate, nano chitosan / glycerol triacetate dispersion liquid is formed, and then in the forming process of the filter rod, the dispersion liquid is used as filter plasticizer to be sprayed on a cellulose acetate tow to form the filter rod. The nano chitosan carried by the glycerol triacetate is evenly sprayed on the cellulose acetate tow.

Description

technical field [0001] The invention relates to the field of manufacture and processing of cigarette materials, in particular to a filter rod for cigarettes loaded with nano-chitosan and a preparation method thereof. Background technique [0002] Chitosan is a deacetylated product of chitin. There are a large number of active functional groups -OH and -NH2 on the chitosan molecular chain. When used in cigarette products, its surface active functional groups may adsorb harmful components in smoke. There have been many reports on the application of chitosan to reduce coke and harm in cigarette smoke. Wang Xiaokui et al. added chitosan solution to cigarettes, which can effectively reduce the content of tar and nicotine in mainstream smoke. They also added chitosan to cigarette filter rods, and found that chitosan with different degrees of deacetylation had obvious reduction effects on total volatile fatty aldehydes in mainstream smoke. Wang Jin et al. found that the efficienc...
