Selective absorbing dry method paper filter material for cigarette filter tip rod and preparation method thereof

Abstract

The invention discloses a selective absorbing dry method paper filter material for a cigarette filter tip rod and a preparation method thereof. The selective absorbing dry method paper filter material is formed by processing 80-100 parts of base material fibers, 0-20 parts of adhesive and adsorbing materials of which the weight is 0.5 percent to 10 percent of that of the base material fibers through a dry method papermaking technology. The preparation method comprises working procedures of fiber net formation, adsorbing material coating and paper making and formation, that is to say, after fiber nets are formed by fibrous raw materials containing hot melting fibers in an air-laid manner and are pre-pressed, the adsorbing materials are evenly sprayed into accumulated fiber net layers, or are sprayed and coated on the front surfaces of the fiber nets after being mixed with the adhesive, and the fiber nets are formed in a rolled manner; after the adsorbing materials are sprayed and coated on the back surfaces of the fiber nets, glue is applied to the fiber nets, the fiber nets are additionally formed in a rolled manner, and then the paper filter material is obtained. By adopting the selective absorbing dry method paper filter material, harmful ingredients such as solid particle matters, nicotine and nicotinamide in cigarette smoke can be effectively reduced, the tar content can be markedly reduced, the cigarette smoking quality can be improved and the cigarette safety can be enhanced. The preparation method of the selective absorbing dry method paper filter material has the advantages of simple and convenient technology, easiness in operation and high practicality.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, further belongs to the technical field of cigarette filter material processing, and in particular relates to a paper filter material for a cigarette filter rod with a selective adsorption function and a preparation method thereof. Background technique [0002] As people pay more and more attention to smoking and health issues, low-tar and low-harm cigarettes are becoming more and more popular and promoted. Harmful components in mainstream cigarette smoke account for less than 1% of tar, most of which are aroma components, which can bring pleasure and physiological satisfaction to consumers, so to some extent, harm reduction The significance is greater than that of reducing focus. Therefore, for Chinese-style cigarettes, the State Tobacco Monopoly Administration proposed that "the harmful components in tar are only a very small part of it. When the tar reduction reaches a certain level...

There is a certain reduction, but at the same time it also significantly reduces the content of the aroma-generating substance tar, which damages the quality of cigarettes

[0005] To sum up, although the prior art adds adsorbent material to the cigarette filter rod as an important means to reduce the harm of smoking, but the prior art is often single The addition of materials is difficult to achieve the purpose of selectively reducing harmful components without reducing the aroma components
