The technical field to which the invention relates
This invention relates mainly to a method for manufacturing cigarette wrapping paper having the transferred pattern of the additive material. More specifically, the invention relates to a method of manufacturing cigarette wrapping paper with a specially prepared material oxidized starch.
Cigarette wrapping paper can be formed with a pattern of additive material to reduce the risk characteristics of fire Smoking products formed with the wrapping paper. Reduced risk characteristics of fire reflect a reduced ability of Smoking products to ignition of the substrate, when the glowing crack product accidentally left without supervision on a substrate.
According to this invention, the predetermined pattern of the additive material containing an aqueous solution of starch, can be applied on the tape basics of wrapping paper. The predetermined pattern can contain multiple transverse strips, a plurality of longitudinal strips, a two-dimensional matrix of the treated areas, or any other suitable pattern. Preferably, the predetermined pattern may be printed using this method of printing, such as gravure printing, offset printing, inkjet printing, spraying, and mA is the hexadecimal format printing or something like that. Most preferably can be used in gravure printing.
To enhance the performance risk of fire, Smoking products, formed from the wrapping paper, the drawing is preferably applied using a printing solution containing oxidized starch. Desirable characteristics of printing can be achieved using an aqueous solution of starch having a viscosity at room temperature of not more than about 50 MPa/s (CP, SP) and made from particles having a size in the range from about 4 microns to about 40 microns in a dry condition, and about 90% of the particles having sizes in the range from about 10 microns to about 100 microns wet. In addition, it is also desirable that the starch solution was slightly acidic with a pH in the range from about 6 to about 6.5. The starch used for the printing solution, preferably can be mixed with water for forming the printed solution having the concentration of starch is from about 20% to about 24% (mass). Other preferred characteristics of the printing solution is relatively high surface tension, for example of the order of 6.5·10-2N/m (65 Dyne/cm) or more.
If desired, print the solution can be applied to the tape base in two or more layers. These layers can joint Atsa vertically with each other, with a shift of one to another, having parts spaced from each other at a distance, and the like. In addition, if desired, a conventional filler, such as calcium carbonate, can be added in one or more layers.
Brief description of drawings
Many of the objectives and advantages of this invention will be obvious to experts in this field when reading this description together with the attached drawings, where similar reference numbers are applied to similar elements and where:
Figure 1 is a schematic view of a deep way of printing;
Figure 2 is a schematic view of a wrapping paper having transversely napechatanie region;
Figure 3 is a schematic view of a wrapping paper having a longitudinally napechatanie region;
Figure 4 is a schematic view of a wrapping paper having a two-dimensional drawing;
Figure 5 a view in section of a multilayer printed area; and
6 is a General view of the Smoking articles having a tobacco rod designed using wrapping paper, are described here.
Typically, the predetermined pattern of the additive material can be applied to the tape basics of wrapping paper to achieve high performance fire risk ("IP"), and so is e to achieve high performance of fire extinguishing ("SE"). The risk of fire is a standard test conducted according to ASTM E 2187-04, "Standard Test Method for Measuring the Ignition Strength of Smoking Articles, which is included here in its entirety as a reference. Fire risk measures the likelihood that Smoking product in cases when it is located on the substrate, will produce enough heat to maintain a constant combustion of the tobacco rod. Are desirable low IP values, because these values correlate with decreased likelihood that the glowing crack product will cause burning in located underneath the substrate.
In addition, the predetermined pattern of the additive material is usually applied to the tape base, having a permeability in the range from about 20 to about 80 CORESTA units. In the dry state, the material additives often form the film on the tape base, which is effective for local reduction of permeability to values in the range from 0 to about 10 CORESTA units. In some applications, the additive material is applied as an aqueous solution containing starch.
Unexpectedly, it was found that the usual characteristics of the starch material form specified drawings, which give a very low risk of fire when Smoking products formed paper backing,which is applied to the image. Even more unexpected was the fact that within standard specifications for some well-known materials starch differences between the various loads can affect the risk of fire to get Smoking products. As an example, the specification of oxidized tapioca starch, commercially available National Starch &Chemical Co. as Flo-Max 8 show a 1% solution pH in the range from 4.5 to 6.5, with particles having a molecular weight above 10,000. Unexpectedly, when the predetermined pattern has been printed on the tape basics using download Flo-Max 8 having a pH in the range from about 6 to about 6.5, the risk of fire, as found, was much higher compared with other downloads Flo-Max 8, for which the pH was less than 6, but still within the manufacturer's specifications.
Various mutual balancing or trade-offs must be made when choosing the parameters of starch for use in films for drawing on brown paper. For example, since most molecular weight starch can cause a decrease in effective permeability, such starches with high molecular weight should be used at low concentrations, which results in obtaining a solution having a very high moisture content. But film with high water content are much harder efficiency is but to dry on a porous wrapping paper. In addition, it was found that the surface tension of a solution of starch causes the retention of small air bubbles - low surface tension allows smaller bubbles to remain in solution, while the high surface tension causes the bubbles to accumulate and to separate from the solution, giving a more homogeneous and stable material for drawing on brown paper.
Although it is not fully understood, the preferred pH range of oxidized starch, as expected, reflects less - or less complete - oxidation of the polymer chains of the starch, which gives more of a long polymer chain, the more acidic (i.e. having a smaller pH) starches. In addition, longer polymer chains result in a solution having a higher viscosity. The higher the viscosity of the starch solution corresponds to the best control when applied to the wrapping paper during printing method.
Based on this knowledge, it was found that a marked improvement in the risk of fire for wrapping paper with a pattern occurs for solutions of starch, having a specific and improved performance. These characteristics for an aqueous solution containing oxidized starch, include a pH in the range from about 6 to about 6.5; the surface tension is not less than the example is about than 6.5·10 -2N/m (65 Dyne/cm); the viscosity at room temperature of not more than about 50 MPa/s and the distribution of particle sizes in the range of 4 microns to 40 microns for particles in the dry state, with approximately 90% of the particles are in the range from about 10 microns to about 100 microns wet. In addition, the particles preferably have a molecular weight that the solution can have a concentration of starch in the range from about 20% to about 24%. Preferably the starch comprises an oxidized tapioca starch.
Aqueous solutions of starch, used for drawing on the ribbon basis or on brown paper, usually prepared by obtaining a mixture of the starch/water by first mixing the desired weight of powder of the dry starch with the desired mass of water at room temperature (i.e. from about 15°C to about 25°C) to obtain a mixture of the starch/water with a preset concentration. For example, in order to prepare a solution of the starch/water with a predetermined concentration of 20%, 20 mass parts of starch are mixed with 80 parts of water mass. Then the solution of the starch/water is heated to the elevated temperature, not boiling in the range from about 90°C to about 95°C, i.e. below the boiling point. A solution of the starch/water provides the camping at elevated temperature for from about 20 to about 30 minutes for heat treatment. Then the solution of the starch/water cools to room temperature. This stage cooling can occur passively, for example by means of natural methods of heat transfer; or stage of cooling can be active (or forced), such as immersion in a cooling bath or the use of traditional mechanical cooling system. At the stage of mixing, heating stage, the stage of thermal impregnation stage and cooling the mixture of the starch/water mix. The mixing may be continuous or essentially continuous. If the extension components, such as calcium carbonate, are added to a solution of the starch/water, these components must be added after the solution of the starch/water returns to room temperature after the stage of thermal treatment.
Aqueous solutions of starches having the above characteristics and prepared as described above can be applied to the tape substrate with the use of a variety of printing technologies, including, for example and without limitation, a group containing gravure printing, offset printing, inkjet printing, spraying and dot matrix printing. Other methods of printing can also be suitable for use and, as expected, are within the concept of the present description. Preferably, however, for the application of the starch solution is to tape the basis for wrapping paper with a pattern can be used in gravure printing.
For example (see Figure 1), the tape basics of wrapping paper 10 can be fed from the reel 12 in a gravure printing system 14, where the predetermined pattern of the starch solution obtained in accordance with the above description is applied to the tape basics 10. The ribbon framework 10 that caused the given figure is going on bobbin Assembly 16. Other conventional stages bobbin 16 of wrapping paper with a pattern can be used for forming tobacco rods for use in the manufacture of Smoking products such as cigarettes.
The gravure printing system 14 may include one, two, three or more printing operations 14a, 14b, 14c. Since these operations are essentially the same, will be sufficient to describe the details of one of them, realizing that the rest have the appropriate details. The starch solution, described above, may be supplied to the tank 20, from which it is pumped, or in some other way is supplied to the gravure roller 22 having a surface with a pattern. This roller 22 rotates in the bath with a solution of starch. During the rotation of the gravure roller 22 a solution of starch is removed evenly from the surface of the drum with the help of the node blade dispensing 23 so that the gravure roller 22 has come into contact with the tape basics 10 in the contact zone between the gravure roller 22 and elastically have been fitted the m opposite the support roller 24, the starch solution is transferred to the ribbon framework using patterns with a pattern on the surface of the gravure roller 22.
After drying the ribbon framework 10 may be connected to one or more printing operations 14b, 14c, where one or more additional layers of the starch material with the same or with a different set of drawings can be applied to the tape basics 10. If desired, the starch material during subsequent printing operations may contain other components, such as calcium carbonate. In addition, if necessary, the starch solution, containing calcium carbonate, could be applied by the first printing operation 14a, although the starch solution without calcium carbonate can be applied when the second or subsequent printing operations 14b, 14c. Ribbon basics 10 (see Figure 2) typically has a transverse or weft direction (arrow 30)and longitudinal direction (arrow 32). The predetermined pattern of the additive material can contain multiple transversely oriented mainly parallel, regions or strips 34. These strips can be placed equally along the length of the master tape 10, or may be in the form of repetitive figures, separated by some space, correlated with long tobacco rod and the receipt of the finished cigarette.
Alternatively, the ribbon framework 10 m which may contain the predetermined pattern, such as one or more longitudinally extending areas or strips 36 (see figure 3) material additives. If necessary, the predetermined pattern may also contain a two-dimensional group of sections 38 (see Figure 4) material supplements along and/or across the tape bases 10.
In addition, as mentioned above, the additive material can be applied to two or more layers 40, 42 (see Figure 5). If necessary, the layers can be fully aligned and coincide with each other. Alternatively, the top layer 42 may be divided or cut into two parts 42a, 42b, each of which is superimposed on the first, or bottom, layer 40 so that there is some space between the two parts 42a, 42b. This space may extend along or across the tape bases 10. As a further alternative, the outer layer 42 may overlap the bottom layer 40, but not necessarily with him completely.
Smoking product (see Fig.6) contains the tobacco rod 205 and the filter 207, which are connected to each other tipping paper 209. The tobacco rod 205 includes wrapping paper 210, which is constructed according to the present concept.

In addition, when in this specification mentions%, it is understood that these percentages are mass, then there are weight percents.
