Problems solved by technology

At present, 90% of cigarette filter rods are composed of a single cellulose acetate. Although some patents disclose adding activated carbon particles to cellulose acetate, the adsorption capacity of activated carbon particles added to cellulose acetate is relatively weak. When the amount of particles is small, the adsorption capacity of cellulose acetate cannot be greatly improved. If the amount of activated carbon particles added is large, the suction resistance of the filter rod increases, and the difficulty of compounding is also greatly increased. Increase

Abstract

The filter rod and the filter tip are made of cellulose acetate with homogeneously mixed active carbon fiber in the amount of 1-10 wt% of the cellulose acetate. Adding the active carbon fiber with nanometer holes can raise the adsorption performance of the filter rod and the filter tip greatly and reduce the volatile harmful matters, such as nitrosamine, benzopyrene, CO, tar, etc in the main smoke flow greatly while producing no obvious increased sucking resistance. Besides, the filter rod and the filter tip with mixed active carbon fiber possesses some anti-fake function.

Description

technical field [0001] The invention relates to a filter stick and a filter tip for cigarette filters, in particular to a filter stick and a filter tip doped with activated carbon fibers. Background technique [0002] At present, with the increasing anti-smoking movement in the world and the general enhancement of consumers' awareness of smoking and health, the tobacco industry is facing more and more pressure. How to reduce the tar and its harmful components in cigarettes while maintaining the quality of cigarettes Smoking flavors to satisfy consumers is the biggest challenge in cigarette design. At present, 90% of cigarette filter rods are composed of a single cellulose acetate. Although some patents disclose that activated carbon particles are added to cellulose acetate, the adsorption capacity of activated carbon particles added to cellulose acetate is relatively weak. When the amount of particles is small, the adsorption capacity of cellulose acetate cannot be greatly ...
