Description

Composite filter stick cigarette Technical Field The invention belongs to the technical field of tobacco industry, and particularly relates to a composite filter stick cigarette. Background Along with the improvement of the living standard of people, cigarettes become an indispensable part of the daily life of many people, but smoke of the cigarettes contains substances harmful to human bodies, such as tar, carbon monoxide, nitroso, free radicals, volatile nitriles, phenols and the like, so that based on the health concept, more and more manufacturers reduce harmful ingredients in the smoke to improve the quality of the cigarettes. CN117322675A discloses a composite filter stick for reducing tar and harm of cigarettes, a preparation method and application thereof, and relates to the technical field of tobacco filter sticks. The cigarette tar-reducing and harm-reducing composite filter stick comprises a first acetate fiber filter stick, a filter stick component and a second acetate fiber filter stick which are sequentially connected, wherein the pore diameter of the first acetate fiber filter stick is smaller than that of the second acetate fiber filter stick, and the filter stick component comprises, by weight, 35-45 parts of thermoplastic elastomer, 25-35 parts of processing oil, 20-30 parts of polypropylene and 2-7 parts of antioxidant. The invention realizes the tar and harm reduction by a step-by-step filtering mode. CN102349702a discloses a filter rod with remarkable tar reducing function, comprising a filter core (1), a coaxial diacetate fiber bundle filter rod (2) wrapped outside the filter core, and forming paper (3) wrapped outside the diacetate fiber bundle filter rod. The invention realizes the organic combination of the coaxial filter stick technology and the paper filter stick technology, and the non-woven filter core, the paper filter core and the paper vinegar composite filter core are implanted into the filter tip in a coaxial mode, thereby not only ensuring the effective adsorption of the filter core to the cigarette smoke, but also keeping the good taste of the cigarette. In the prior art, the content of harmful components in smoke is reduced by adjusting the structure of the acetate fiber filter stick or combining the acetate fiber filter stick with the paper filter stick, but the acetate fiber can effectively adsorb and intercept smoke tar, but is not easy to degrade, and the paper filter stick has obvious odor and other problems. Therefore, how to reduce the consumption of acetate fibers and not reduce the effect of the filter stick on smoke filtration, and meet the requirements of reducing tar and harm of cigarette smoke becomes a problem to be solved. Disclosure of Invention Aiming at the defects and actual demands of the prior art, the invention provides a composite filter stick cigarette. The special structure of the composite filter stick cigarette can reduce harmful chemical components in the smoke without affecting the sensory experience of a user.
