(57) Abstract:The invention relates to products of the tobacco industry, in particular to cigarettes. Shell cigarette includes a layer of paper with water-repellent derived from cellulose. Derivative of cellulose, in particular ethyl cellulose, is applied in several layers in an amount of from 1 g/cm2. Derivative of cellulose may be printed on paper with two sides using a roller coating method of gravure printing. The invention provides reduced penoobraznaya shell of the cigarette when the air permeability of 20 to 50 units by the CORESTA standard. 3 C.p. f-crystals. The invention relates to products of the tobacco industry, in particular to cigarettes.Known cigarettes, tobacco extrusion which is surrounded by a layer of paper with water-repellent impregnation of a derivative of cellulose, in particular ethyl cellulose.The disadvantage of these known cigarettes is the formation of spots on cigarette paper, spoiling the appearance of products and raising doubts about their quality.Buyers cigarette review white, not containing spots appearance cigarettes, as an indication of quality. Even the EU to have a color change, 't worse taste when Smoking manufacturers should focus on market forecasts.The formation of stains on the cigarette paper can be explained by the fact that dissolved in the places of contact between the paper and the tobacco particles contained in tobacco substances can penetrate the paper, as it is both porous and hydrophilic.One would imagine that the formation of stains on the cigarette paper can be reduced by covering it with some substances that make the paper completely impenetrable. Such coatings have been proposed to cause rapid shutdown pending cigarettes. In order to be able to control the content contained in the smoke substances, the manufacturer of cigarettes, in General, interested, however, in certain air permeability of cigarette paper. The problem is thus that, on the one hand, to withstand the paper permeable to air, and on the other hand, to reduce the permeability to dissolved constituents cigarettes.In US-A 5 143 099 to solve was asked to run the shell cigarettes of two layers of paper, with the inner shell has a very high Pronichev is here to make the inner shell is water-repellent with an additive of 0.5% dimer of alkylbetaine.Compared with the prior art, the basis of the invention lies task is to make unnecessary the use of two layers of paper, namely, due to the impregnating substance, no adverse impact as possible, there is little change taste when Smoking and prevent the formation of spots on the shell of cigarettes.This task was trying to solve due to the fact that cigarette tobacco extrusion supplied by shell comprising a layer of paper with water-repellent impregnation of a derivative of cellulose, in particular, of the ethyl cellulose. European patent EP 0 419 981 shows just such a cigarette, in which, however, the permeability is below 5 units standard CORES.The invention is based on the fact that the impregnation can be made thin enough to obtain the desired air permeability, because it is applied in several layers. According to the invention, therefore, provides that to achieve breathability shell, at least 20, preferably at least 50 CORESTA standard derived cellulose was applied in several layers.Various derivatives of cellulose meet the physical conditions relative to sirovaniya cellulose ethers and esters of cellulose (for example, nitrocellulose). Preferred, however, is ethylcellulose, as it is harmless with a sufficient degree of reliability - it corresponds to the German regulations for tobacco - and practically does not change the taste when Smoking.Other details of the invention are discussed further on the basis of the comparative experiments.Cigarette paper with a weight per unit area of 26 g/m2was covered with a layer of azeotroping cellulose (CAP) or acetobutyrate cellulose (CAB) or ethyl cellulose (EC) method of gravure printing using a roller coating. The amount of deposited material was approximately 0.7 g/m2. Using the thus obtained cigarette paper were manufactured cigarettes.To test the vulnerability of the sunspot cigarettes in Packed and unpacked condition were subjected to exposure either at 20oC and 60% relative humidity, or when 30oC and 80% relative humidity. Test spots (in each case on 100 cigarettes) was carried out immediately after production and after 24 and 48 hours Analysis was performed according to the size of the spots and their number. Through skits results were translated into a point system.Although the paper is coated with a layer of ethyl cellulose, found relatively strong exposure to the sunspot (high points), and further improvements were carried out with this material, as with CAP and CAB was found undesirable change in the character of the smoke. However, when using paper coated with a layer of the EU, was also primarily found to be significantly less exposure to the sunspot compared with paper, on which was not coated with the layer. About a month later, however, the cigarettes manufactured with the use of paper, covered with a layer of the EU, was a small dark spots, while the cigarettes are made of paper, not coated with a layer made large yellow spots. On this basis, an assumption was made that because of defects in the coating to penetrate the paper dyes, the distribution of which is prevented by the coating. Due to these reasons, experiments were repeated with double-coated paper, i.e., cigarette paper, covered with 1/4 g/cm2EU. Thus, susceptibility to stains, according reproduced above method of calculation, declined to 56 points, i.e., in comparison with single coverage, by ten percent. This striking result confirm the although the porosity of the paper, before coating was 50 CORESTA standard, after coating was still 20 units standard CORES. The first experiments with highly porous paper from the source material to confirm that and at the end of porosity 50 CORESTA standard radical reduction of exposure to the sunspot (one standard CORESTA (CU) shows how many cm3of air per minute flows through the surface of the paper 1 cm2under the pressure of a water column height of 10 cm). 1.
