The technical field to which the invention relates.

The present invention relates to tissue paper products for Smoking, which reduces the amount of smoke in the visible side stream tobacco smoke.

Prior art

Cigarette with a small side stream smoke, with a small amount of smoke formed in the side stream smoke, was created in recent years. The so-called method using a camera with a lower end part having the form of a fish-tail allows you to determine whether or not this cigarette has a small amount of smoke formed in the side stream smoke or not. The way in which a camera is used with the lower end part having the shape of a fishtail, described in detail in the description of the Japan patent (Kokai) No. 10-81 with reference to the drawings. Briefly describing this method, we can say that when this method is used, the flue gas chamber having an open lower end part, which is given the shape of a fishtail. Cambridge filter with a diameter of 44 mm, installed on the top of the smoke chamber. A given area of the cigarette is subjected to static burning in the lower end portion of the smoke chamber by the suction of air at a rate of 3 liters per minute through the upper end portion of the smoke chamber. There is the possibility of adhesion of a solid is astiz, contained in the side stream smoke, which is formed at this stage, for the Cambridge filter and the inner wall of the smoke chamber, and measure the mass of adhering solid particles. More precisely the mass of the source of the Cambridge filter is subtracted from the mass of the Cambridge filter with captured solid particles in order to obtain a first mass of solid particles adhering to the Cambridge filter. After that, the solid particles adhering to the Cambridge filter, and the solid particles adhering to the inner wall of the smoke chamber, isolated from the solvent in order to measure the spectral absorption ability. Then calculate the mass of solid particles adhering to the inner wall of the smoke chamber, on the basis of the relationship of the absorbance values obtained in this way, and from the mass of solid particles adhering to the Cambridge filter, which was defined in the beginning (I mean the value obtained by the subtraction as described above). The amount of smoke in side stream smoke per cigarette (mg/CIG.) obtained by adding the mass of solid particles adhering to the Cambridge filter, with a mass of solid particles adhering to the inner wall of the smoke chamber. In addition, when using this method are the amount of smoke in side stream smoke per unit time (mg/is in) by measuring the time, required for static combustion section of the cigarette with a specified length, and by dividing the amount of smoke in side stream smoke one cigarette at a time, measured in this way. When creating a normal cigarette with a small side stream smoke, the amount of smoke in side stream smoke per unit time, thus obtained, was considered as approximately equal to the amount of smoke in the visible side stream smoke.

On the other hand, the proposed device for serial or instantaneous measurement of the amount of smoke in side-stream cigarette smoke optical method is not based on measurements of the mass (description of Japan patent No. 3-120444. In this optical device on a side stream of smoke created by cigarettes, hot inside the combustion chamber, direct the luminous flux and measure the intensity of light passing through a side stream of smoke. The intensity of light measured thus, the concentration of side stream smoke and, therefore, reflects the amount of all solid particles.

However, it was found that in the case when dealing with cigarettes, you can reduce the amount of smoke in side stream smoke to the same low level, when assessing it using the mass of all solid particles, as in the method using a camera with a lower end part of being a fish-tail the amount of smoke in side stream smoke is often different from the amount of smoke in side stream smoke, actually measured visually on stage Smoking. This confirms that the amount of smoke in side stream smoke, as measured by mass of all solid particles that do not necessarily correspond to the amount of smoke in side stream smoke, as measured by visual observation. Since optically measured amount of smoke in side stream smoke, above, also corresponds to the concentration of side-stream smoke, it can be argued that the optically measured amount of smoke in side stream smoke does not necessarily correspond to the amount of smoke in the side stream, measured by visual observation.

The closest analogue is the wrapping paper for the product area for containing paper pulp, calcium carbonate 30-60 wt.%, soda clay 5-30 wt.%, salt is an alkali metal, as a chemical additive for regulating the combustion of 0.5-10 wt.%, and 2-30 wt.% kaolin, and the paper weight is 20 to 70 g/m2(EP 0791688, C And 24 D 1/02, op. 1997).

This source of calcium carbonate can save the side stream smoke reducing effect on the pulp. This effect decreases when the amount of calcium carbonate increases. The effect of reduction of side stream smoke is only then when calcium carbonate combined with calcined clay and kaolin. The same should be said about the impact of burning regulator, which shows this effect only in combination with the above components.

This patent does not disclose and does not allow the visible side of the stream, which is its disadvantage. The shortage can be attributed to the complexity of the composition.

It is desirable that the product for Smoking, such as cigarettes, provided not only a small mass of all solids, not a small amount of smoke in side stream smoke is actually measured by visual observation.

Based on the foregoing objective of the present invention is to create wrapping paper for products for Smoking, which can ensure the reduction of smoke in side stream smoke, as measured by visual observation (sometimes referred to hereinafter also referred to as the amount of smoke in the visible side stream smoke).

Disclosure of inventions

As a result of intensive studies, which were conducted in order to achieve the above objective, the authors of the present invention have found that the amount of smoke in the visible side stream smoke can be significantly reduced by treating calcium carbonate in the specified quantity and substances for regulating combustion in the set to which Icesave in tissue paper products for Smoking. The present invention was made based on the received data.

Thus, in accordance with the present invention proposed wrapping paper for products for Smoking, which reduces the amount of smoke in the visible side stream tobacco smoke, with wrapping paper contains not less than 30 g/m2calcium carbonate and at least 3 wt.% substances for the regulation of burning.

In the present invention the substance to regulate the combustion is preferably selected from the group consisting of potassium citrate and sodium citrate.

In addition, in the present invention it is also desirable that the ash content in the surface layer at least on one side of the wrapping paper does not exceed 35 wt.%, and that the ash content in the surface layer on each of two sides, i.e. upper and lower sides of the wrapping paper does not exceed 35 wt.%.

The best way of carrying out the invention

Hereinafter the present invention will be described in detail.

Fibrous mass, used for wrapping paper for products for Smoking according to the present invention, consists of flax fiber and pulp, wood pulp or similar fibrous pulp, used for ordinary wrapping paper for products for Smoking (especially cigarettes). It is advisable to use a fibrous mass in a quantity sufficient to maintain the mechanical strength required for paper production process or for wrapping tobacco. repectfully number of the pulp is from 20 to 50 g/m 2.

Wrapping paper for the product to area according to the present invention contains at least a specified number of calcium carbonate and it added at least a specified number of substances for regulating combustion. Calcium carbonate is contained in an amount of 30 g/m2or more and 50 g/m2or less, and a substance for regulating the combustion is added in an amount of from 3 to 15 wt.%. In that case, if the amount of calcium carbonate is less than 30 g/m2and/or amount of a substance for regulating the combustion will be less than 3 wt.%, there is a possibility that a sufficient effect of reducing the amount of smoke in the visible side stream smoke is reached.

Calcium carbonate is added in the form of particles. It is desirable that the diameter of the particles of calcium carbonate, which can be selected appropriately considering the cost and ease of use in the papermaking process, was within the range from 0.02 to 10 microns.

It is desirable that the mass of 1 m2wrapping paper made from 50 g to 100 g

As substances to regulate combustion, it is desirable to use a salt of citric acid alkali metal. In particular, it is preferable to use potassium citrate and sodium citrateas a substance for regulating combustion. Potassium citrate and sodium citrate could the t can be used individually or in combination.

It should be noted that in the paper, which added filler and which is produced using clinocerinae paper machine, the amount of filler with side mesh paper machine will be less compared to the amount of the filler cloth (upper) side of the paper with regard to dehydration from the grid during the formation of a layer of paper. As a result, when the distribution of the filler and the fibers in the paper creates a "shift" in the direction of thickness of paper (or in the direction of the Z axis). As a consequence, creates a paper, which will have different properties from two sides. There is the possibility that these different properties from the two sides will lead to defects in terms of print quality and characteristics of paper, intended for use as printed (printing) paper. However, in ordinary wrapping paper different properties from two sides is desirable from the point of view of the deposition of ash on the stage of burning cigarettes, and other adverse effects : rarely causes problems in practice.

However, if the paper contains a very large amount of filler, as is the case in the present invention, will be manufactured using conventional clinocerinae paper machine, the filler contained in large quantities on the surface of the cloth sides of the paper,will fall in the process of manufacturing cigarettes, what contributes to problems such as defect manifested in the transformation of paper into a powder, and a defect in the wrap. From this it follows that in the manufacture of cigarettes with high speed problems.

To overcome the problems described above, it is necessary to reduce only the amount of filler distributed near the surface, while maintaining the amount of the filler contained within the wrapping paper. As a means to reduce only the number of filler distributed near the surface, while maintaining the amount of the filler contained within the wrapping paper, you can use a paper machine in which the paper is formed using a double wire section dehydrating type. Bilateral wire section dehydrating type means wire section with two nets. This paper machine is a twin-wire papermaking machine or the machine is supplied with part of the grid, which is a grid of so-called top type or a hybrid grid, where the dual mesh is used as part clinocerinae paper machine. In normal clinocerinae paper machine dehydration is performed only from the grid during the formation of a layer of paper. One is for a paper machine twin-wire type layer of paper is formed due to dehydration from the two grids, in contact with the upper and lower surfaces of the paper material used for paper production, in order to provide the possibility of reducing the amount of filler contained in the surface area of wrapping paper. Wrapping paper, produced using a conventional clinocerinae paper machine, has the highest content of filler on the cloth surface, and the content of the filler is gradually reduced in the direction of the surface mesh. On the other hand, wrapping paper, produced by the paper machine twin-wire type, the difference in the content of the filler between the inner area and the surface area of the layer of paper is small, and therefore the difference in the content of the filler between each layer of paper and each puffs will be very small. In this regard, in the present invention, the area in the thickness direction away from the surface of a wrapping paper that matches from 18 to 20 wt.% from the whole mass of wrapping paper, is defined as the surface layer, and the ash component in this zone is defined as the ash component of the surface layer. In addition, in the case when the tissue paper is produced using a conventional clinocerinae paper machine, the front and rear surfaces made of wrapping paper, as is ravelo, called respectively the surface on the cloth side and the surface on the side of the net. On the other hand, in the case when the tissue paper is produced using a paper machine twin-wire type, front and rear surfaces produced wrapping paper called respectively the surface on the side of the upper grid and the surface on the side of the bottom grid. In the present invention the cloth side and the upper side of the grid are referred to as the upper side and the side of the net and towards the bottom of the grid are referred to as the lower side. In the present invention, it is desirable that the ash component, at least one surface layer on the upper side or the lower side of the wrapping paper was not more than 35 wt.%, and more preferably, the ash component in the surface layer is not each of the upper and lower sides of the wrapping paper was not more than 35 wt.%.

It should be noted that to determine the ash component in the surface layer of the sample wrapping paper is not shared by several parts in the thickness direction of the sample wrapping paper, and the ash component in the surface layer corresponding to 18-20 wt.% from the whole mass in the thickness direction from the surface of the sample can be determined in accordance with Japanese industrial standard P 8128. Here is what the Scripture means of determining the ash component in the surface layer, above.

The sample size of 40 mm × 200 mm cut out of wrapping paper and measure the mass of the sample. After this adhesive tape (width 50 mm, tesax/#4267) attached to the surface of the sample so as to avoid the formation of air layer over the entire area of the sample from one edge to another edge of the sample. After the portions of the adhesive tape, which hang down from the edges of the sample will be cut off, to the upper side of the adhesive tape from the top to put the load in order to ensure strong adhesion of pressure sensitive tape to the sample. Again measure the mass of the sample with attached adhesive tape in order to get a lot of masking tape. Then another sticky tape attached to the opposite surface of the sample, and the sample is enclosed between the two adhesive tapes are divided in its longitudinal direction into two parts by using the force of adhesion of adhesive tapes. More precisely, the sample is divided by the T-shaped separation, in which the sample is enclosed between two adhesive tape to hold vertically and slowly separated in a horizontal direction with constant speed. Additional sticky tape again attached to the surface, resulting from the separation of the sample subjected to the first separation process, and a similar operation is repeated by datech long while the mass of the surface layer will not be from 18 to 20 wt.% from the mass of the original sample. Ten points of the surface layer of one sample, thus obtained, is strongly heated to a temperature of 900°together with masking tape to get the ash component in accordance with Japanese industrial standard P 8128, and thus obtained ash content is correct with regard to the ash component adhesive tape in order to get the value of the ash component of the surface layer. In addition, the ash content of the sample before separation of the sample is also determined separately for the total ash content.

Wrapping paper for products for Smoking (in particular for cigarettes) in accordance with the present invention can significantly reduce the amount of smoke in the visible side stream tobacco smoke compared with conventional wrapping paper. Measuring the amount of smoke in the visible side stream smoke, which can be done using organoleptic control can also be easily performed by using a device for measuring the amount of smoke in the visible side stream smoke disclosed in the patent application of Japan No. 2000-268910.

Figure 1 is an isometric projection, schematically showing the construction of a device intended to measure the number is the amount of smoke in the visible side stream smoke, which is disclosed in the patent application of Japan No. 2000-268910, and figure 2 is a block diagram schematically showing the construction of a device designed for measuring the amount of smoke in the visible side stream smoke.

As shown in figures 1 and 2, a device 10 for measuring the amount of smoke in the visible side stream smoke contains the camera 11 static burning for products for Smoking, the device 12 for emitting visible light, intended for exposure to side stream smoke from the static combustion products for Smoking and naturally rising up inside the chamber 11 static burning, with a given beam of visible light passes in a direction essentially perpendicular to the direction in which the side stream smoke, and the device 14 to determine the intensity of scattered light as the indicator of the amount of smoke in the visible side a stream of smoke, when it is determined by the intensity of scattered light scattered by the side stream smoke in the direction essentially perpendicular to the direction of the beam of visible light.

The camera 11 static combustion formed of lightweight protective shielding material and, for example, consists of a housing in the form of a hollow parallelepiped, having a longer side in the vertical direction and Bratanova four side walls 11a-11d. In the lower part of the side wall 11a is formed a hole 111 for inserting products for Smoking, designed to insert products SA Smoking area, such as a lit cigarette. In most of the lower end parts of the four side walls 11a-11d, forming a chamber 11 static burning, formed Windows 112-115 for the passage of air, such as a mesh window that allows air flow required for static combustion products SA for the area in the camera 11 of the static burning. It is desirable that the hole 111 for inserting products for the area was established to avoid the adverse impact on stream SSS smoke formed by the product SA for Smoking, is inserted into the chamber 11 of the static burning through hole 111 for inserting, from the perturbations caused by the external air flowing into the chamber 11 of the static burning through the window 112-115 for the passage of air, and to the hole 111 was located so that the distance between the product SA for the area and the top of the camera 11 static burning was large enough to essentially prevent rotation of the side jet SSS smoke in the horizontal direction.

You can place glass beads (not shown) in the free space in the lower part of the chamber 11 static burning, surrounded by Windows 112-115 for the passage of air, so that bratati layer for "straightening" of the air flow, thereby preventing the disturbance of side jets SSS of smoke rising up inside the chamber 11 static combustion due to static combustion products for Smoking. The upper end of chamber 11 static burning remains open. There is a possibility of installation of exhaust hood 15 in the open upper end of the chamber 11 static burning for pumping air from the chamber 11 static burning. You need to pump out air from the chamber 11 static combustion thus, in order not to have a significant impact on the static burning products SA for the area. For pumping, it is desirable to set the filter 16 to the straightening of the stream so that it crosses the upper open end of the chamber 11 static burning, so as not to cause disturbance side jet SSS of smoke rising in a natural way up inside the chamber 11 static combustion due to static combustion products for Smoking. Exhaust duct 151 is installed on the upper part of the exhaust hood 15 and the exhaust duct 151 is connected to a pumping system (not shown).

The device 12 for emitting visible light installed outside of the camera 11 static burning. In the example shown in the drawings, the device for emitting visible light are installed on the outside of the side wall 11b facing the side wall 11a of the chamber 11 static the sky's burning, into which is inserted the product SA for the area. Box 116 for transmission of visible light is formed in the portion of the side wall 11b, which is located so that it is facing toward the device 12 to emit visible light. The device 12 for emitting visible light contains a source (not shown) of visible light and is used for the irradiation side of the jet SSS smoke generated as a result of static combustion products SA for the area and rising natural way up inside the chamber 11 static burning beam VLB visible light passing in the direction essentially perpendicular to the direction of passage of the side stream smoke. Used source of visible light is not limited in a particular way, provided that there is the possibility of radiation of visible light. For example, you can use the laser visible range, the light emitting diode visible range or halogen lamp as the source of visible light. In a typical case, as the source of the visible range of the source is used As light as stipulated by the International Committee on illumination.

The beam VLB visible light (a flux of visible light)emitted from the device 12 to emit visible light, has a significant cross-section large enough to cover sufficiently the side stream SSS of smoke rising natural clicks the zoom up inside the chamber 11 static burning, even if the side stream SSS smoke will slightly fluctuate and deviate in the horizontal direction. For example, there is a possibility that the beam VLB visible light had a width W in the direction perpendicular to the direction of radiation (figure 2), and had a rectangular cross-section having a height in a direction essentially perpendicular to the direction of the radiation beam VLB visible light, which corresponds to the area of review when performing sensory evaluation taking into account the field of view of the person. It is desirable that the width W was at least equal to the width of oscillation of the visible side of the jet SSS smoke in the direction perpendicular to the direction of radiation of the beam of visible light. In this regard, the cross-sectional shape of the beam of visible light is not limited to a rectangular shape. The cross-sectional shape of the beam of visible light may be elliptical, circular, etc. giving a specific shape to the beam of visible light can be performed in a known manner. For example, there is the possibility of using a template having an aperture corresponding in shape to the cross-sectional beam of visible light. There is also the possibility of using a lens system that includes a convex lens and a concave lens are used in combination.

It is desirable to place the device 13 for absorbing the light with Aruji camera 11 static burning, if that's the example shown in figure 1, this device is located outside of the side wall 11a, so that the device 13 for absorbing light is located so that it is facing toward the device 12 for the emission of visible light, to allow the absorption and removal of all components of the light generated by the device 12 for emitting visible light and passed through the side jet SSS smoke. Box 117 for transmission of visible light is formed in the portion of the side wall 11a, which is located so that it is addressed to the device 13 for absorbing the light.

The device 14 to determine the intensity of scattered light is located outside of the camera 11 static burning in the direction perpendicular to the direction of the irradiating light beam emitted from the device 12 to emit visible light. In the example shown in figure 1, the device for determining the intensity of scattered light is located outside the side wall 11d. The window 118 for transmission of visible light is located in the part of the side wall 11d, which is located so that it is facing toward the device 14 to determine the intensity of scattered light. As described above, the device 14 to determine the intensity of scattered light is used to determine the intensity of scattered light SLV (light scattered at an angle of 90°), which is assailed in the direction essentially perpendicular to the direction of the radiation beam VLB visible light, among the light rays irradiating side stream SSS smoke and dissipating side stream SSS smoke. The device 14 to determine the intensity of the scattered light includes an optical system (not shown)intended for the information of the light rays SLV scattered at an angle of 90°and a device (not shown) for converting light into an electrical signal, which is in itself known and is designed to convert the flattened beam of light SLV scattered at an angle of 90°into an electrical signal and outputting the electric signal. As a device for converting light into an electrical signal, mentioned above, can be desirable to use a photomultiplier tube that converts light into a signal voltage. The converted voltage signal is subjected to, for example, analog-to-digital conversion and then can be used to sample discrete data by using a personal computer. The interval between the reception data and the reception can be set as desired. Typically, 300 values can be measured with an interval of 0.2 seconds in one minute.

The measured light intensity SLV scattered at an angle of 90°and the amount of smoke visible in obecnej stream smoke is very well correlated with each other. Therefore, we can conclude that the amount of smoke in the visible side stream smoke is relatively large with the increase of the measured intensity of light scattered at an angle of 90°. In this regard, it was found that the intensity of light scattered at an angle of 90°and the number of all solid particles contained in the side stream smoke, do not correlate with each other.

In order to prevent scattered light radiation penetrating from the outside, in each of the Windows for the transmission of visible light, it is desirable to place the camera 17-19 for washed down from the external scattered light radiation between the device 12 for emitting visible light and a window 116 for transmission of visible light between the device 13 for light absorption and box 117 for transmission of visible light and between the device 14 to determine the intensity of scattered light and the window 118 for transmission of visible light.

Regarding typical examples of all the dimensions of the device 10, the camera 11 static burning is a hollow parallelepiped, having a cross section with dimensions of 11 cm × 11 cm and a height of 80 cm Hole 111 for inserting articles for area formed in a place located at a distance of 50 cm from the bottom edge of the camera static burning. The distance between the product SA for the area and center the beam of visible light is 10 see In addition, the beam of visible light emitted from the device to emit visible light, has a cross section with dimensions of 5 cm × 5 see

As shown in figure 2, it is desirable that the device for measuring the amount of smoke in the visible side stream smoke used in the present invention contain a means 20 in the form of a mapping table used for converting the intensity of light scattered at an angle of 90°that was defined with the help of the device 14 to determine the intensity of the scattered light, the amount of smoke in the visible side stream smoke on the basis of the relationship between the intensity of light scattered at an angle of 90°and the amount of smoke in the visible side stream smoke, measured by visual observation, and intended to issue the converted amount of smoke in the visible side stream smoke. Received in advance the relationship between the intensity of light scattered at an angle of 90°and the amount of smoke in the visible side stream smoke obtained by visual observation, is injected into the tool 20 in the form of a mapping table in the form of the equations of transformation, calibration curve, etc. in order to enable the conversion of the signal intensity of the light scattered at an angle of 90°, issued by the elimination of the ETS 14 to determine the intensity of the scattered light, the amount of smoke in the visible side stream smoke. The amount of smoke in the visible side stream smoke resulting from such conversion, "generated" using means 20 in the form of a conversion table. To obtain the correlation between the intensity of light scattered at an angle of 90°and the amount of smoke in the visible side stream smoke, measured by visual observation, the amount of smoke in the visible side stream smoke products for Smoking, such as cigarettes, evaluated by organoleptic evaluation on the two samples in order to quantify the amount of smoke in the visible side stream smoke. The intensity of the light scattered at an angle of 90°that is determined by the device, measured in relation to the same product area. It is possible to obtain a calibration curve by plotting a graph based on the measured values, while the y-axis lay, for example, the amount of smoke in the visible side stream smoke, and the abscissa axis lay, for example, the intensity of light scattered at an angle of 90°. There is the possibility of obtaining the equations of transformation of the intensity of light scattered at an angle of 90°in the amount of smoke in the visible side stream smoke on the basis of receiving the Noah thus the calibration curve.

Organoleptic control by organoleptic evaluation in two different samples can be performed by using, for example, the device for estimating the amount of smoke in the visible side stream smoke, shown in figure 3. More precisely, a regular cigarette CIG1 and investigated ["target"] cigarette (target cigarette) CIG2 is subjected to static burning inside two corresponding chambers 31 and 32 static burning, which are located symmetrically in the direction from right to left. In this case, it uses a challenge-response system in which a request is made to obtain quantitative estimates derived from observations of the amount of smoke in side stream smoke, which created the investigated cigarette CIG2, within the range of from scoring 0 to scoring 10 relative scoring 5 specified for a standard cigarette CIG1. The camera 31 and 32 static combustion is performed with the appropriate Windows 311 and 321 for observation, each of which has a predetermined width in a vertical direction. In addition, relevant sources 33 and 34 of the visible light is provided in the upper parts of the chambers 31 and 32 static burning. It is desirable that the width of each window 311 and 321 for observation in the vertical direction corresponds to the height of the beam of visible light emitted from the device 12 to emit visible with the ETA, available in the device for measuring the amount of smoke in the visible side stream smoke. It is also desirable that the distance between the cigarettes CIG1, CIG2 and lower ends of the window 311, 321 for observation corresponded to the distance from the lower end of the beam of visible light emitted by the device 12 for emitting visible light, available in the device for measuring the amount of smoke in the visible side stream smoke, to products SA for the area. Side streams SS1 and SS2 smoke irradiated from the top beam of visible light, which are emitted by sources 33 and 34 of visible light, and these side streams SS1 and SS2 smoke can only be observed through the window 311 and 321 for observation.

Hereinafter the present invention will be described in more detail with reference to examples of implementation of the present invention, but the present invention is not limited to the following examples.

Reference example 1

The values corresponding to the amount of smoke in the visible side jets of smoke created by cigarettes 15 species, were evaluated by organoleptic evaluation on the two samples mentioned above. The valuation was carried out 10 members of the Commission to assess the quality of the cigarettes through the use of the device for estimating the amount of smoke in the visible side stream smoke, which is shown in figure 3. The average of the obtained values for each type of cigarettes was defined as a score for garety a certain type. In addition, the above values were normalized by setting 1 (unit) value corresponding to the amount of smoke in the visible side stream smoke formed cigarette, which received the highest score. On the other hand, the intensity of light scattered at an angle of 90°, defined as the voltage corresponding to the amount of smoke in side stream smoke from the same 15 kinds of cigarettes, by using a device for measuring the amount of smoke in the visible side stream cigarette smoke, which is shown in figure 1, and the voltage values for cigarettes were normalized so that the voltage value obtained for cigarettes, which was given a score of 1 when performing the organoleptic assessment, above, is taken equal to 1. These data are plotted on the graph in figure 4, the abscissa axis which delayed the normalized intensity of the scattered light, and the ordinate axis is the normalized value corresponding to the amount of smoke in side stream smoke, as measured by sensory control. As follows from figure 4, the intensity of light scattered at an angle of 90°that obtained using the device for measuring the amount of smoke in the visible side stream smoke is very well correlated with the amount of smoke in the visible side stream smoke, measured with organoleptic the definition of control.

Example 1

Was prepared wrapping paper with fiber (cellulose) in an amount of 30 g/m2and containing about 4.5 wt.% potassium citrate, the amount of calcium carbonate was changed as shown in table 1. Flax fiber mass was used as a fibrous mass, and spindle-shaped particles of calcium carbonate type of calcite (calcium feldspar)having a particle diameter average of 3.0 μm, were used as calcium carbonate. Cigarettes were formed by using the obtained tissue paper. The resulting cigarette had normal size FK at which the circumference was 4.9 mm, the length of the column of tobacco was 59 mm, a filter length was 25 mm and the length of the paper mouthpiece was 32 mm fine-cut tobacco Used was tobacco type American blend (American mix), which is used in cigarettes available on the market, and the filling was 0,580 g per cigarette. These cigarettes were subjected to conditioning at a temperature of 22°C and 60% relative humidity and then selected by weight, with the weight of one cigarette was set at the level 0,885±0,01, Then cigarettes were put to the test.

Each of the selected cigarettes was subjected to static burning, when it was set to the length of garaudy part, component 49 mm, table 1 also shows the time of combustion, the amount of smoke in side stream smoke per cigarette and the amount of smoke in side stream smoke per unit time, measured by the method using the camera with the lower end part having the shape of a fishtail. The amount of smoke in side stream smoke per cigarette is also shown in figure 5. In addition, the amount of smoke in the visible side stream smoke generated from each cigarette was measured by using the device shown in figure 2, the results are shown in table 1 and figure 6. Experimental data confirm that in the case when the amount of calcium carbonate is small, the amount of smoke in side stream smoke per cigarette is large (figure 5). However, since the time of combustion is clearly a large amount of smoke in side stream smoke per unit of time as specified by the method using a camera with a lower end part having the form of a fish-tail is small. On the other hand, if the amount of calcium carbonate is large, the time value would be small. Despite the fact that the amount of smoke in side stream smoke per unit time is small, because the amount of smoke in side stream smoke per cigarette is clearly small, there is no noticeable change in the amount of smoke in side stream smoke per unit time, identified through the method using the camera with the lower end part having the shape of a fishtail. On the other hand, the experimental data shown in Fig.6, acknowledge those that smoke in the visible side stream smoke can be quickly reduced if wrapping paper will contain calcium carbonate in an amount of not less than 30 g/m2.

Example 2

Wrapping paper was prepared by adding varying amounts of potassium citrate, as shown in table 2, in tissue paper containing 35 g/m2calcium carbonate as in example 1, it was found that this paper provides the possibility to considerably reduce the amount of smoke in the visible side stream smoke. Other conditions were the same as in example 1. Table 2 also shows the time of combustion, the amount of smoke in side stream smoke per cigarette and the amount of smoke in side stream smoke per unit time, measured by the method using the camera with the lower end part having the shape of a fishtail. The amount of smoke in side stream smoke per cigarette is also shown in Fig.7. In addition, the amount of smoke in the visible side stream smoke for each whitefish is Yety was measured by use of the device, shown in figure 2, and the results are shown in table 2 and Fig. Experimental data confirm that in the case when the amount of potassium citrate is significant, the combustion time is prolonged. However, since the amount of smoke in side stream smoke is obviously great (Fig.7), the amount of smoke in side stream smoke per unit of time, which was measured by the method using the camera with the lower end part having the form of a fish tail, was great. On the other hand, if you increase the amount of potassium citrate combustion time decreases. However, because the amount of smoke in side stream smoke one cigarette can be significantly reduced (Fig.7), the amount of smoke in side stream smoke per unit of time, which was determined using the method using the camera with the lower end part having the shape of a fishtail, decreased, although the reduction was not large. However, experimental data on Fig, confirm that the amount of smoke in the visible side stream smoke has declined, when it was used wrapping paper that contains at least 3% potassium citrate.

Table 3 also shows the time of combustion, the amount of smoke in side stream smoke per cigarette and the amount of smoke in side stream smoke per unit time, measured by the method using the camera with the lower end part having the shape of a fishtail. The amount of smoke in side stream smoke per cigarette is also shown in Fig.9. In addition, the amount of smoke in the visible side stream smoke of each cigarette was measured by using the device shown in figure 2, and the results are shown in table 3 and figure 10. Experimental data confirm that in the case when the amount of potassium citrate is small, the combustion time is prolonged. However, since the amount of smoke in side stream smoke is obviously great (Fig.9), the amount of smoke in side stream smoke per unit of time, which was measured by the method using the camera with the lower end part having the form of a fish tail, was great.
