Description

A kind of ternary tobacco fiber paper filter stick of composite herb and its preparation method

technical field

The invention relates to the technical field of cigarette filter sticks, and more specifically relates to a three-element tobacco fiber paper filter stick with composite herbs and a preparation method thereof.

Background technique

Cigarette smoke contains particles, commonly known as tar. Tar contains a large number of chemical components, 4000 to 5000 kinds, all of which are products of incomplete combustion of tobacco. In addition to tar, cigarette smoke contains other substances, such as the "steam" or "gas" phase, which also includes volatile tobacco combustion substances such as acetaldehyde and other low molecular weight components. Other phases in cigarette smoke, such as the "semi-volatile" phase, which includes many combustion substances, are equivalent to particulate and vapor phases.

Cigarette filter rods can filter smoke components. Cigarette filter rods are composed of filter elements and molding paper. The filter element of existing filter rod all is to adopt acetate fiber or polypropylene fiber to form generally. Because these fiber-containing filter elements are in direct contact with the lips of the human body, recently there have been media reports that fibers, especially polypropylene fibers, may enter the human body along with the smoking of cigarettes and cause damage to human health. 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.

At present, there are some reports of plant fiber tobacco filter sticks in the prior art, for example (Patent No. 200910185294) reports a plant fiber tobacco filter stick and its preparation method. However, the patented filter rod is directly composed of rice straw fiber, wheat straw fiber, tobacco straw fiber and soybean straw fiber. Can not provide more functions that meet the requirements of the cigarette filter rod.

Cigarette filters made of crepe paper were first introduced to the European cigarette market in the 1920s. Paper filters have a stronger ability to remove tar and nicotine than acetate fibers, but consumers have not accepted them until the 1950s. With the development of acetate in the 1990s, filter cigarettes only began to gain widespread acceptance among consumers, mainly because the paper had a "paper smell," which consumers often disliked. Moreover, the paper is relatively soft, and the pollution is serious during the smoking process, so it is not suitable to be directly used as a filter tip. At present, the filter tip made of acetate fiber is widely used. With the continuous pursuit of health by consumers, the filters made of cellulose acetate and prepared from chemical substances are gradually being resisted because of their unnatural characteristics. But there is no new material that can completely replace cellulose acetate.

The prior art adopts air-laid paper as the technology of preparing cigarette filter rod filter material and has also been developed, most of which adopt wood pulp fiber as the main fiber material, or supplemented by a certain proportion of composite fiber, hot-melt fiber or ecological fiber to achieve their respective The goal. Such as the Chinese patent (CN180167B) "dry paper cigarette filter rod and its preparation method", which adds 5% to 65% of heat-melting sheath-core fiber in the wood pulp fiber; another example of the Chinese patent application (CN101171981A) Elementary composite cigarette filter rod” uses the material prepared by puffed dry-laid paper as the filter element of the elemental filter near the shredded tobacco. The material is directly composed of pure wood pulp or 50% to 95% wood pulp and 5% to 50% composite fiber; There is also a Chinese patent application (CN101624756A) "Nonwoven fabric for biodegradable cigarette filter and its preparation method" which uses wood pulp fiber, high melting point polylactic acid fiber, low melting point polylactic acid fiber and water-soluble glue. There are also people who directly transport the tobacco fibers to the forming section through the blower to form a fluffy and uniform fiber web on the forming belt, and then through sizing, preheating, rolling, curing and forming to make cigarette filter paper, and Natural herb waste raw materials are added during the molding process. The fibers used for these airlaid papers involve fiber types such as wood pulp fibers, composite fibers, hot-melt sheath-core fibers, and polylactic acid fibers. Although these fibers can be used to make filter materials for filter tips, they filter smoke while making smoke There is a lot of loss of aroma, and a certain amount of woody gas is brought in, which has a certain negative impact on the taste and taste of cigarettes during smoking, and cannot guarantee the quality of cigarettes. What is more important is that the color and quality of these existing materials are consistent with natural The feeling of tobacco is very different, and it cannot cater to the pursuit of cigarette consumers for the feeling of natural tobacco.

In recent research, some people have also applied tobacco fiber in dry-laid papermaking, and the tobacco fiber is transported to the forming section by a fan for laying and forming, and a fluffy and uniform fiber web is formed on the forming belt. Then through sizing, preheating, rolling, curing and molding to make cigarette filter paper, and add natural herb waste raw materials in the molding process. However, its technical solution is still made by laying simple tobacco fibers, and it is bonded with various colloids, so it is not effective in removing miscellaneous gases, and using too much colloid will bring peculiar smell to the cigarette holder. In addition, It does not solve the problem of reducing tobacco waste, and adding additional tobacco fibers in the production process increases the tobacco consumption of the whole cigarette.

In addition, the existing cigarette manufacturers produce a lot of waste during production, such as discarded tobacco leaves, tobacco powder, debris, tobacco stems, etc. The current utilization of these wastes is mainly for the purpose of reducing coke and adding these wastes to cigarettes after reprocessing However, as we all know, the amount of these materials added to cut tobacco is very limited, which cannot completely solve the problem of waste disposal in tobacco production enterprises and the efforts to turn waste into treasure.

At present, there is no new paper filter material that can completely replace cellulose acetate and give consumers a natural tobacco feeling.
