Paper cigarette filter rod filter media and processing method thereof

Abstract

The present invention discloses a paper cigarette filter rod filter media and a processing method thereof, wherein the paper filter media is obtained through performing a dry process on the following components: 40-74% of natural cigarette fiber, 4-40% of bast fiber, 1-12% of natural tobacco waste raw material, and 4-20% of adhesive. The method comprises the following steps: raw material processing, main fiber mixing shaping, waste material adding and prepared paper shaping process. After the natural tobacco fiber is mixed with the bast fiber, discongestion is performed. After sufficient dispersion, the mixed material is conveyed to a shaping section through a blower for being laid on a net and shaped. A fluffy and uniform fiber net is formed on a shaping net belt. The cigarette filter media paper is obtained through adhesive applying, preheating, roller pressing, solidifying and shaping. As the cigarette fiber is used as the main fiber raw material, the paper cigarette filter rod filter media according to the invention has reduced foreign gas of wood and settles a problem that the fragrance quality is reduced by the foreign gas of wood in the prior-art paper filter rod. The natural tobacco waste raw material is added in the paper shaping process. Not only is whole aesthetic quality of the cigarette improved, but also the tobacco raw material is uniformly distributed in the dry process paper and does not easily drop off. The quality of the filter rod is more stable.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and further belongs to the technical field of cigarette filter material processing, in particular to a paper cigarette filter rod filter material and a processing method thereof. Background technique [0002] The filter tip is an important part of the cigarette, and the harmful substances in the mainstream smoke of the cigarette can be filtered out by using the absorbent material and its additives in the cigarette filter tip. At present, there are three main types of filter media: acetate fiber, polypropylene fiber and paper. Paper filters have attracted much attention due to their higher smoke retention efficiency and easier degradation than discarded acetate and polypropylene filters. The traditional paper used as filter material mainly adopts wet-laid production process, but wet-laid paper requires a lot of water in the papermaking process, which leads to problems such as excessive...

AI Technical Summary

Problems solved by technology

[0005] In summary, there are many deficiencies and defects in the air-laid paper in the prior art when it is used as a filter material for cigarette filter rods: First, it causes a lot of loss of cigarette aroma while filtering smoke, and brings in certain woody impurities. Second, although coating or sprinkling tobacco stalk particles on the finished paper can improve the taste of cigarettes, the tobacco stalk particles are easy to fall off from the surface of the paper, which is not conducive to the formation of the filter rod and affects the filter quality. Consistent rod quality
