Description
Technical Field
The invention belongs to the technical field of cigarette filter rods, and particularly relates to a preparation method of a low-irritation cigarette filter.
Background
Cigarette smoke irritation refers to a slight or significant unpleasant sensation caused by smoke on the sensory organs, such as irritation to the mouth, throat, and nasal cavity. The irritation is influenced not only by the quality of the cigarette itself but also by the smoking environment, and is greatly influenced by the fact that smoking cigarettes in a relatively humid environment is relatively less irritating, while smoking cigarettes in a dry environment is significantly more irritating. The climatic conditions of the south and the north are very different, the south is wet, and the north is dry. It is almost impossible to achieve the higher smoking quality of cigarettes of the same specification in the north and south. This brings great trouble to each large cigarette enterprise to expand the market scale and enhance the market competitiveness of the product. In the actual production of the cigarette industry, a method for reducing the irritation in the cigarette smoke is to add a humectant into the cut tobacco, besides adjusting the cigarette formula. At present, most of humectants added into tobacco shreds in the tobacco industry are polyalcohol compounds, such as glycerol, propylene glycol, xylitol, sorbitol and the like. The compounds have a plurality of hydroxyl groups and water molecules which can form chemical bonds, so that the compounds have certain hygroscopicity, and the moisturizing performance of glycerol and propylene glycol is better. However, the addition amount of the humectant directly affects the smoking quality of cigarettes, the effect is not obvious due to insufficient addition amount, and miscellaneous gas and other negative effects are caused due to excessive addition amount. Therefore, the addition amount of the general cigarette humectant must be accurately controlled within the range of several thousandth of the weight of the cut tobacco, so that the effect can be ensured.
The filter tip is an important component of cigarette, and is made up by adding plasticizer (commonly called adhesive) into filter material and rolling it with filter tip forming paper (see cigarette paper), and is aimed at retaining tar and nicotine of cigarette and reducing their content, and the most commonly used filter material for producing filter tip is acetate fibre. The cigarette filter can reduce harmful substances in cigarette smoke to a certain extent, and greatly reduces the harm to the body of a smoker. However, the cigarette filter brings new problems, the filter core material of the cigarette filter rod commonly used at present generally uses acetate fiber or polypropylene tow fiber, and because of the characteristics of the acetate fiber and the polypropylene tow fiber, the harmful ingredients in the cigarette smoke are difficult to be filtered sufficiently and effectively.
In order to solve this problem, other types of filter rods have been developed, for example, chinese patent publication No. CN103110190A, entitled "filter tip of cigarette made of loofah sponge fiber and method for manufacturing the same", which discloses a filter using loofah sponge and acetate fiber as components, which can reduce the content of tar and the like compared to the conventional filter made of acetate fiber or polypropylene tow fiber, but has the following disadvantages: firstly, need carry out the denaturation to the silk melon collaterals, the technology is complicated, and the cost is higher, secondly to the filtering of harmful substance such as tar, still has the space of further improvement. Patent cigarette filters (application No. CN03822154.3, published 2005-10-12) disclose a cigarette filter capable of reducing the amount of aldehydes in cigarette mainstream smoke, mainly by adding an inorganic alkaline substance to reduce the amount of aldehydes in cigarette, and although it is proposed to add glycerin as a moisturizing agent, there is no description about the amount of glycerin added, nor is there any description that the cigarette filter can reduce cigarette smoke irritation. The patent discloses a filter rod for low-tar cigarettes (application number: CN201110183856.3, published 2011, 11 and 16), which discloses a filter rod for low-tar cigarettes, the filter tip is prepared by loading one or more humectants selected from malto-oligosaccharide alcohol, D-galactopyranosyl acid, L-2-pyrrolidone-5-sodium carboxylate, propylene glycol, glycerol, xylitol, sorbitol, plant extracted trimethyl glycine proline, 1, 3-butanediol, D-pyran and honey on expanded tobacco stem particles in a proportion of 0.5-2% of the weight of the expanded tobacco stem particles, the filter rod needs to add expanded particles, has complex procedures, is not beneficial to the distribution of the humectant in the filter, although the patent mentions in the summary of the invention that the filter rod has the effect of improving the smoking quality of cigarettes, but does not describe the technical scheme and the technical effect that the filter tip can reduce the irritation of the cigarette smoke.
