Filtering material for cigarette filter tip and its preparation method

Abstract

The invention discloses a filter material for cigarette filter and the preparation method. Based on the expanded cabo particles from <The Preparation Method of an Expanded Cabo Particles and Relevant Equipment> (Application No.: 200710065892.3), the expanded cabo particles are extracted, shaped and selected as so to become the required filter material. The filter material utilizes the waste in the cigarette production, which not only has significant economic benefits, but also is not necessary to be recycled, and will not cause the abrasion of equipment and affect the sensory quality of cigarette. The filter material is uniformly arranged on the filter tows so as to make a composite filter; as the composite is applicable to the cigarette, the smell of the cigarette will be more clear and soft, and the tar and nicotine content in the smoke gas can be reduced effectively. The invention has the advantages that: the operation is simple; the effect is remarkable, therefore the invention has a good applicable prospect.

Description

technical field [0001] The invention belongs to the technical field of cigarette material preparation, and in particular relates to a novel filter material used for cigarette filter tips. At the same time, the invention also relates to a preparation method of the filter material. Background technique [0002] The advent of filter-tipped cigarettes in the 1960s effectively reduced the amount of tar in cigarettes. The contribution of cigarette filters to reducing harmful components such as tar and nicotine in cigarettes lies in the mechanical filtration of particulate matter in the smoke by the filter rod. When the cigarette is smoked, the smoke enters the mouth through the filter, and the particulate matter in the smoke Immediately after contact with the filter fiber tow, it is stuck and cannot be returned to the air stream. Therefore, the effect of cigarette filter on reducing harmful components such as tar and nicotine is the most significant and effective. [0003] The ...

AI Technical Summary

Problems solved by technology

[0007] First, due to the high strength of these materials, in the process of cutting the filter rod after forming and cigarette rolling and cutting, the wear and tear of the cutting blade is relatively large, resulting in an increase in equipment costs and an increase in downtime accidents

[0008] Second, due to the lack of toughness of these materials, it is easy to generate dust due to abrasion during cigarette manufacturing and transportation

On the one hand, these dusts will enter the mouth of smokers along with the smoke, endangering the health of smokers; on the other hand, because the aroma of Chinese-style flue-cured tobacco cigarettes is relatively fragile, these dusts are mixed in the smoke, causing cigarettes to produce different degrees of miscellaneous gas , such as "earth smell", "charcoal smell", etc.

[0009] Third, in the process of cigarette production, packaging, and transportation, it is inevitable that some filter materials will fall off from the filter tip and enter the shredded tobacco, which will affect the combustion performance and state of the cigarette, and at the same time cause the instability of the smoking quality of the cigarette.

[0010] Fourth, the unqualified cigarettes that appear in the cigarette production process are easily polluted by the above-mentioned filter materials during the recycling process. Therefore, the unqualified products of composite filter stick cigarettes made of these filter materials are generally not recycled. Disposal of waste products seriously causes loss of tobacco leaf raw materials

[0011] The existence of the above problems has seriously restricted the wide application of composite filters on Chinese cigarettes
