Filter stick for cigarette

Abstract

The invention discloses a filter stick for a cigarette. The filter stick comprises an acetate fiber filter stick section, an active carbon filter stick section and a middle section, wherein the acetate fiber filter stick section is connected with the middle section; the middle section is positioned between the acetate fiber filter stick section and the active carbon filter stick section; and the active carbon filter stick section is connected with a cigarette body. Due to the adoption of the filter stick, the using quantity of acetate fiber tows is reduced, the consumption of wood pulp is lowered, and the natural environment is protected. The middle section is introduced, so that the design flexibility of a cigarette product is enhanced. By changing the lengths and pressure drops of three sections of materials, a ternary composite filter stick with different filtering efficiencies can be designed to meet the requirements of different products. Various functional tar reducing and harm relieving additives can be loaded into the middle section of the cigarette, so that a cigarette with low tar content and low harm is produced. Moreover, the active carbon filter stick is compounded in the filter stick, so that the functions of harmful substances in the cigarette can be weakened, and the smoking safety of the cigarette is enhanced.

Description

technical field [0001] The invention relates to a cigarette, in particular to a cigarette filter rod and a production method thereof. Background technique [0002] At present, cigarette filter rods mainly include cellulose acetate filter rods, grooved filter rods, etc., and the main raw materials of these filter rods are cellulose acetate tow. [0003] The main raw material of cellulose acetate tow is special wood pulp, and the availability of special wood pulp is limited, but the market demand for cellulose acetate tow is increasing year by year, resulting in a shortage of cellulose acetate tow, thus limiting the production of cigarette companies capacity and increase production costs. [0004] Therefore, it is necessary to design a novel filter rod for cigarettes to solve the above problems. Contents of the invention [0005] Aiming at the defects of the prior art, the object of the present invention is to provide a filter rod for cigarettes which can save the consumpt...
