Abstract

The utility model discloses a novel cigarette filter rip. The novel cigarette filter tip is composed of packaging paper (1) and a filter body (2). The filter body (2) is coated by the packaging paper (1) coats; the filter body is of a two-section structure which sequentially comprises a core-shell particle-added section (21) and an acetate fiber section (22), the core-shell particle-added section (21) is composed of core-shell particles (211) and acetate fiber bundles (212), and the length of the core-shell particle-added section (21) is 1.0-2.0 cm; and every core-shell particle (211) is composed of a core body (2111) and a surface film (2112), and the particle diameter of the every core-shell particle is 100-700 mu m. The novel cigarette filter tip has a small influence on the flavor of a cigarette and meanwhile reduces the content of hazardous substances such as tar in the smoke, thereby protecting the health of a smoker better.

Description

new cigarette filter

technical field

The utility model relates to a cigarette filter tip, in particular to a novel cigarette filter tip.

Background technique

The filter tip refers to the non-combustible part connected to the back of the cigarette to filter the tar in the smoke and reduce the discomfort of smoking. Currently, most cigarette filters are made from acetate tow. The mainstream smoke produced during the burning of cigarettes and inhaled into the smoker's body contains more than 4,000 chemical substances, including hundreds of chemical components that are harmful to the human body. These chemical substances are miscible or agglomerated with each other to form particles of different sizes, which are dispersed in the gas phase material and are in the state of aerosol. Cigarette filters reduce particulate matter in mainstream smoke mainly by increasing the collision agglutination frequency and adsorption of smoke particles. In order to reduce the harmful components in mainstream smoke and reduce the unpleasant taste such as spicy, some cigarette filters add porous activated carbon particles, but it is found that these activated carbon particles are more likely to absorb volatile aroma components, which affects the inherent flavor of smoke.

Contents of the invention

In order to solve the above-mentioned technical problems existing in the prior art, the utility model provides a novel cigarette filter, which is composed of a wrapping paper and a filter body, the wrapping paper is wrapped on the filter body, and the filter body is two The segment structure is sequentially a core-shell particle adding segment and an acetate segment, and the core-shell particle adding segment is composed of core-shell particles and acetate tow.

Further, the length of the adding section of the core-shell particles is 1.0-2.0 cm.

Further, the core-shell particles are uniformly dispersed in the cellulose acetate tow, and the addition amount is 0.5-3.0 mg/mm length.

Further, the core-shell particles are composed of a core and a film, and the particle size is 100-700 microns.

Further, the surface film has a thickness of 1.0-10.0 microns and is rich in microporous structures with a pore diameter of less than 1 micron.

The core material of the new cigarette filter tip of the present utility model endows the particles with necessary strength and shape, and its porous surface film has the functions of preventing volatile substances from contacting the core material and increasing the adsorption capacity of tar particles. The structure is more favorable to improve the selective adsorption of tar particles.

Compared with the prior art, the novel cigarette filter tip of the utility model has the characteristics of less adsorption of volatile aroma substances and higher selective adsorption of particulate tar substances in smoke. While slightly affecting the flavor of cigarettes, it can effectively reduce the content of tar substances and harmful substances in smoke, so as to better protect the health of smokers.

Description of drawings

Fig. 2 is a schematic diagram of the structure of core-shell particles in the novel cigarette filter.

Detailed ways

As shown in Fig. 1, the novel cigarette filter tip of the present utility model is made up of wrapping paper 1 and filter body 2, and described wrapping paper 1 is coated on described filter body 2, and described filter body 2 is two-stage structure, followed by Core shell particle addition segment 21 and acetate segment 22 . The core-shell particles adding section 21 is composed of core-shell particles 211 and cellulose acetate tow 212, and the length is 1.0-2.0 cm. The core-shell particles 211 are evenly dispersed in the cellulose acetate tow 212, and the addition amount is 0.5-2.0 cm. 3.0 mg/mm long.

As shown in Figure 2, the core-shell particle 211 is composed of a core body 2111 and a surface film 2112. microporous structure. The acetate segment 22 is composed of acetate tow 213 and has a length of 0.5-2.0 cm. The core body 2111 of the used core-shell particles 211 is composed of activated carbon, pulverized dry plant bodies and their powder granulation products, and the main component of the surface film 2112 is cellulose acetate.

The cigarette filter tip of the utility model can effectively reduce the contents of tar substances and harmful substances in the smoke while less affecting the flavor of the cigarettes, thereby better protecting the health of smokers.
