As can be seen from figure 2, the results showed that the paintings pyrolysis conventional cigarette paper or comparative example 2 without cover and cigarette paper with strips of servicemonitoring, gamerboy resin and Gellan gum, similar to each other. In contrast, it is shown that the pattern of pyrolysis conventional cigarette paper without coating and painting pyrolysis of cigarette paper with a coating of material to give a low propensity to ignite containing titanoboa gum and sodium alginate (which is available on the market fireproof paper.

Thus, the analysis showed that it is possible to produce fire-safe cigarettes, not different in taste from regular cigarettes when cigarette paper made using servicemonitoring, gamerboy resin or Gellan gum, which indicates to Rhino pyrolysis, similar to the pattern pyrolysis conventional cigarette paper.

Experimental example 2

The intensity of combustion was measured using the standard method of measuring the intensity of combustion, developed by the National Institute of standards and technology (NIST)established by the standard ASTM2187-04 and accepted for use by the government of the state of new York (USA) and the canadian government, using cigarettes, manufactured in accordance with examples 1-4 and comparative examples 1 and 2. The results are presented in table 2.

Tests the ability of the cigarettes to the damping, which consist in checking whether a cigarette, put on ten layers of filter paper, to continuously burn and generate heat for the fire, were repeated for the production of 40 times. Tested product can be certified as fire-safe cigarettes, when the ratio of the fully burnt cigarettes does not exceed 25% (i.e. more than 75% of the natural damping).

Further, the product in which the cigarette paper coated with the coating material to give a low propensity to ignite, must satisfy the condition of having two or more identical strips located in the cigarette, and at least one strip is located at a distance of more than 15 mm from the end of a cigarette.

The test was repeated 20 times with whitefish is the raeti, manufactured in accordance with examples 1-5 and comparative example 1.

As can be seen from table 2, the results showed that cigarette in accordance with the invention, produced according to examples 1-5, have a higher combustion rate in comparison with cigarettes in comparative example 1, and titanova gum is the best of the coating materials to give a low susceptibility to fire.

Although the analysis showed that the fully burnt cigarettes were not less than 25%, according to the estimate of this was due to the fact that the coating material to give a low propensity to fire was caused not by using precise manufacturing processes and in laboratory scale. And since currently sell fire-safe cigarettes with the use of sodium alginate, that is, in comparative example 1, it was concluded that the application of the coating material to give a low propensity to ignite able to meet the standard requirements for fire-safe cigarettes.

Experimental example 3

Was measured the number of components of smoke (tar and nicotine) in the main smoke stream of cigarettes in accordance with examples 1-5 and comparative examples 1 and 2 was measured by the number of puffs. The results are shown in figure 3.

As can be seen from the results in figure 3, the analysis of dormancy the hall, that the amount of tar and nicotine the same in all cigarettes in examples 1-5 and comparative examples 1 and 2. Therefore, cigarette in accordance with the invention, containing cigarette paper coated to give a low propensity to ignite, were subjected to analysis of taste according to the needs of the smoker.

Experimental example 4

Test sensory perception when Smoking was carried out on five criteria (taste before Smoking, the taste in the process area, causticity in the process area, harmonious taste in the process area and the General taste in the process area) with the score on 15-point system in cigarettes manufactured in accordance with examples 1-5 and comparative example 1, a staff of 25 professionals testing sensory perception. This was followed by quantitative descriptive analysis (paired t-test). The results are presented in figure 4.

The test was performed on the basis of criteria that influence the preference of smokers when choosing a cigarette.

- Taste before Smoking: means a property that should not be present in the initial taste or aroma of the cigarette before Smoking and is a factor that reduces the value of the product; the stronger the taste, the evaluation of the closer to 15 points.

- Taste in the process area: means the property to which e must not be present in the initial taste or aroma of the cigarette in the Smoking process and is a factor which reduces the value of the product; the stronger the taste, the evaluation of the closer to 15 points.

- Causticity in the process area: means feeling like thorns prick, causticity, or burning in the mouth, throat or nose lasting more than one second, and feeling a sudden intensity, which then slowly fades out. The more causticity, the evaluation of the closer to 15 points.

- Harmony in the process area: means the degree of harmony between the added flavor and created by the smoke, and the level of experience that the flavor is not separate, not too strong and not too weak. The higher harmony and balance, the evaluation of the closer to 15 points.

- The overall quality of the taste of the cigarette during Smoking: means the aggregate properties of the smoke, the wealth, richness and harmony in the taste of smoke and the intensity of the taste of the cigarettes, which are not individually, but in General. The higher the intensity, the score is closer to 15 points.

Results of sensory crack test carried out by the special staff on the touch test, presented in figure 4. According to the results of sensory test between all tested samples were not significant differences. Therefore, the analysis showed that there would be large differences in the initial taste of the cigarette between cigarette according to this invention, coated with the coating material is La giving a low propensity to ignite, and cigarettes made with the use of sodium alginate, which is used in conventional commercially available fire-safe cigarettes.

Experimental example 5

For comparison and evaluation of the form of ash generated in the process of Smoking cigarettes manufactured in accordance with examples 1-4 and comparative example 1, the touch test on the integrity of the ashes was carried out according to four criteria (integrity ash, the color of ashes, the line of combustion and formation of spots) with the score on 15-point system by a staff of 25 professionals testing sensory perception. This was followed by quantitative descriptive analysis (paired t-test). The results are presented in figure 5.

The test was repeated 5 times on the test criteria after natural burning cigarettes and shooting the remaining ashes closeup of using a digital camera.

The following is a detailed description of the test criteria.

- The integrity of the ashes: the phenomenon of dispersion, surface cracks, the formation of rags, etc. remains whether the ash after combustion of the cigarette as a single mass or hardened; the greater the degree, the evaluation of the closer to 15.

- The color of ashes: the color of ash after combustion usually appears white, gray or black; blacker than he is, the estimate is closer to 15.

- Line combustion: cigarette paper also burns instead of the f with a burning cigarette; the more the curve is the line of combustion or stronger combustion on the one hand, the evaluation of the closer to 15.

- Staining (staining): indicates the degree of blackening of cigarette paper from inside the firing line; the stronger staining, the score is closer to 15.

The results of the integrity test of the ashes of the staff evaluation test are presented in figure 5. According to the criteria of integrity ash, the color of ashes, and the firing line between samples was not significant differences.

However, staining was significantly worse in cigarettes containing cigarette paper in comparative sample 1, coated with sodium alginate. Thus, the analysis showed that cigarettes containing cigarette paper according to this invention coated with the coating material to give a low propensity to inflammation and help improve the quality criterion of spots in containing the band part, which was a problem in the conventional fire-safe cigarettes.
