Abstract
The utility model relates to a cigarette filter-tip, which comprises filtering fibre and a wrapper. The filtering fibre is composed of at least three sections of fibre of different materials compounded and abutting jointed. Thereof, at least a section is activated carbon fiber, and the position of the activated carbon fiber section is arranged at the midsection of the filter-tip or is closed up to the section of tobacco shreds. The utility model has the advantages that an activated carbon fibre filter section which is 30-50 mg is added in the cigarette filter-tip. The poisonous substances in the cigarette can be filtered efficiently by making use of the superior adsorbability of the activated carbon fibre. The effect is far superior to the simplex acetate fibre filter-tip, and also obviously superior to the activated carbon particle filter-tip.
Description
The utility model belongs to the cigarette filter tip that adopts activated carbon fiber.
Activated carbon fiber is emerging in the world in recent years a kind of sorbing material, and it is big tens times to tens times than granule activated carbon to the adsorption capacity of multiple material.
The purpose of this utility model is that activated carbon fiber is applied on the cigarette filter tip product, proposes a kind of novel filter tip technical scheme, makes it can reduce the harm of cigarette to the smoker effectively.
Content of the present utility model comprises filter fiber and bag paper, and filter fiber is made of the fiber composite butt joint of unlike material more than two sections at least, wherein has at least one section to be activated carbon fiber, and the position of activated carbon fiber section is located at stage casing with filter tip or presses close to the pipe tobacco section.Filter fiber can be that the fiber butt joint of two sections unlike materials constitutes, and then wherein pressing close to the pipe tobacco section is activated carbon fiber, and another section is acetate fiber or paper fiber.If the butt joint of the fiber of three sections unlike materials of filter fiber constitutes, then its interlude is an activated carbon fiber, and two sections of two ends can be acetate fiber or paper fiber.The raw material that activated carbon fiber adopts can be the viscose glue cotton fiber, the fine fiber of propylene, cellulose fibre, lignin fibre or pitch fibers.The weight of activated carbon fiber is advisable with 30～50mg.
The utility model has the advantages that the activated carbon fibre filtering section that in cigarette filter tip, adds one section 30～50mg, the good absorption property that utilizes activated carbon fiber is the noxious material in the filtering cigarette effectively, its effect is far superior to simple acetate fiber filter tip, also obviously is better than the active carbon particle filter tip.
Embodiment of the present utility model is as shown in drawings:
Fig. 1 is the filter tip of two sections filter material butt joints, and wherein pressing close to pipe tobacco is activated carbon fiber for one section.
Fig. 2 is the filter tip of three sections filter material butt joints, and its interlude is an activated carbon fiber.
Number in the figure is respectively:
1. filter tip, 2. cigarette, 3. activated carbon fiber, 4. acetate fiber, 5. bag paper.
In conjunction with the accompanying drawings the utility model is specified:
Fig. 1 is the filter tip of two sections filter material butt joints.By the filter-tip that filter tip 1 and cigarette 2 one are formed, butt joint activated carbon fiber 3 and acetate fiber 4 in the filter tip bag paper 5.Wherein activated carbon fiber 3 is pressed close to pipe tobacco, and acetate fiber 4 places the outer end.Fig. 2 is the filter tip of three sections filter material butt joints, and activated carbon fiber 3 places between two sections acetate fibers 4.Acetate fiber 4 in the filter tip of two kinds of structures can replace with the paper fiber, also can replace with other resin filter material.It is that to consider that the activated carbon fiber outward appearance is black not attractive in appearance that activated carbon fiber 7 places the filter tip core, is not to be that the filtering technique requirement is far from it can not.
The utility model sample with filter tip is through performance measurement, to radioactivity 210Po in the cigarette and 210Pb, TPM, the filtration result of noxious materials such as tar, nicotine, BaP, toluene, benzene, acetone, hydrogen cyanide, methyl alcohol and acetaldehyde all obviously are better than the acetate fiber filter and chew.Filtration result to radioactivity 210Po and 210Pb is chewed identical with the compound filter of Filtrone activated carbon of Britain, chew filtering efficient height than the compound filter of Japanese seven-star board activated carbon, the filtration result of TPM and tar is all chewed to good than Filtnona and the compound filter of seven-star board.
Claims (5)
1, a kind of cigarette filter tip, comprise filter fiber and bag paper, it is characterized in that filter fiber is made of the fiber composite butt joint of unlike material more than two sections at least, wherein have at least one section to be activated carbon fiber, the position of activated carbon fiber section is located at stage casing with filter tip or presses close to the pipe tobacco section.
2, cigarette filter tip as claimed in claim 1 is characterized in that filter fiber is the fiber butt joint formation of two sections unlike materials, and wherein pressing close to the pipe tobacco section is activated carbon fiber, and another section is acetate fiber or paper fiber.
