The filter stick for cigarette is an important raw material in tobacco industry, consists of a filter element and a piece of wrapping paper, and has the function of reducing tar and harmful components. The filter element of the common filter stick is made of chemical fibers such as acetate fiber, acrylic fiber and the like or a paper core. The adsorption function of the filter element and the tobacco flavor felt by smokers are in conflict: the adsorption function of the filter element is strong, and the fragrance of the tobacco leaves is reduced greatly; when the flavor of the tobacco leaves is well maintained, the adsorption function cannot be too strong, and the contradiction cannot be solved by the common filter stick. Researchers develop a method for directly adding the additives including the cigarette blasting beads, the microcapsules, the nanoparticles, the powdery particles and the fragrant substances into the filter stick, and the like, the cigarette blasting beads have good overall acceptance, and the additives including the nanoparticles, the powdery particles and the like can increase the adsorption function and reduce the suction of harmful substances such as tar, nicotine and the like, but in practical application, the following problems still exist: (1) the materials filter part of aroma while filtering smoke, so that the aroma of the cigarettes is weakened; (2) these materials are prone to generate dust in the processing process, which causes environmental pollution and harms the health of operators. (3) Because the particles are fine, there is a risk of dropping, contaminating the equipment during processing, and safety concerns for smoking are easily raised for the consumer. (4) The flavor substance is directly added into the filter stick, so that the flavor stability is not easy to control; the aromatic plant is directly adopted to prepare the flavor-enhancing particles, and certain ingredients in the aromatic plant can generate negative sensory effect during smoking; the flavor enhancement effect is single, and the application is not flexible enough. For example, application No. 201010241592.8, entitled: the filter stick containing tobacco particles and the preparation method thereof are Chinese patent, the tobacco particles are added in the filter core of the filter stick, the tobacco particles adopt tobacco leaves and tobacco powder as main raw materials, the tobacco particles are used as additives after being treated by the processes of crushing, corrosion prevention, granulation, fumigation, flavoring and the like, and are scattered in filter stick tows, and then the filter stick containing the tobacco particles or the filter stick with a composite structure is prepared by a filter stick forming machine.
The addition of the cigarette popping beads and the dropping pills also has certain disadvantages, including the problems of low forming rate, higher cost and the like, and the solvents of the cigarette popping beads and the dropping pills, such as olive oil, ODO and the like, have trace unpleasant odor, so that the cigarette popping beads are mainly used for wrapping essence and spices with strong fragrance, such as ginseng, mint and the like.
