BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same reference numerals are used for the same or similar components throughout the specification. In the case of publicly known technologies, a detailed description thereof will be omitted.

Hereinafter, a low-ignitability cigarette paper and cigarette according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3. FIG.

FIG. 1 is a perspective view schematically illustrating a cigarette according to an embodiment of the present invention, FIG. 2 is a cross-sectional view schematically showing a cigarette according to an embodiment of the present invention, and FIG. 3 is a cross- Fig.

1 and 2, a cigarette 1 includes a cigarette column portion 10, which is burnt by fire, and a cigarette filter portion 20, which filters the cigarette smoke. . The cigarette crest 10 may be surrounded by a cigarette paper 19 and the cigarette filter portion 20 may be surrounded by a cigarette filter wrapper 28. The cigarette crest portion 10 and the cigarette filter portion 20 may be connected by a tipping paper 29. The circumference of the cigarette may be from about 5 mm to about 30 mm. The cigarette filter portion 20 may be omitted.

The cigarette crest 10 includes a cigarette tobacco 11 cut from leaf tobacco processed by various methods.

The cigarette filter unit 20 may include a first filter unit 21. The first filter unit 21 may be formed of acetate tow, paper, or the like. The cigarette filter portion 20 may be a multiple filter including two or more filter members. For example, referring to FIG. 3, the cigarette filter unit 20 may include a second filter unit 22 and a third filter unit 23. In addition, the cigarette filter portion 20 may include three filter members and four filter members.

The cigarette filter portion 20 may include an adsorbent, a flavoring agent, and the like. For example, the adsorbent may be activated carbon or the like, and the flavoring agent may be a herb flavoring substance or the like. In a multiple filter, the one or more filter elements may comprise at least one of an adsorbent and a flavor agent. For example, referring to FIG. 3, at least one of the second filter portion 22 and the third filter portion 23 may include at least one of an adsorbent and a flavor agent.

The cigarette paper 19 includes at least one coating portion 18. For example, the coating portion 18 may be in the form of a band, but may have various other shapes. The number, thickness, and shape of the coating portions 18 may be variously modified, and the intervals of the plurality of coating portions 18 may be variously modified. The coating portion 18 can lower the degree of porosity of the cigarette paper 19. When the cigarette reaches the coating portion 18, the amount of oxygen flowing into the cigarette tips 10 decreases, Can be digested. The cigarette paper 19 may include a coating portion 18, which may be referred to as a low-inflammability cigarette paper.

The surface energy of the coated portion may be about 75 to 85 mN / m. Within the above range, the cigarette paper coating layer is stabilized and oxygen inflow by the coating layer is reduced, so that the burning strength can be improved.

The coating portion 18 is coated with a coating composition. For example, the porosity of the cigarette paper 19 can be about 120 cu or less, and the porosity of the coated portion 18 can be about 5 cu to about 20 cu. The thickness of the base paper of the cigarette paper may be from about 30 탆 to about 100 탆, and the basis weight of the base paper may be from about 15 g / m 2 to about 60 g / m 2 . The thickness of the coating portion 18 may be less than about 5 [mu] m and the basis weight of the coating portion 18 may be less than about 20 g / m < 2 >. The weight ratio of the coating composition to the total weight of the cigarette paper (19) and the coating composition may be about 40% by weight or less. If the coating portion 18 is band-shaped, the mass of the coating composition per band may be approximately 2.5 mg or less.

The coating composition may include solids, ethanol, and water comprising at least one of starch, starch derivatives, gums, gum derivatives, or polymers.

For example, the solids may include pregelatinized starch and maltodextrin. Alpha starch may be a pregelatinized corn starch. As another example, the solid content may include at least one of potato starch, corn starch, tapioca starch, guar gum, stamper, polylactic acid (PLA) resin, or acrylic resin.

Alpha starch can be prepared by rapid drying of raw starch at high temperature, which is also referred to as alpha processing. For example, alpha starch can be prepared by heating about 40% live starch solution to greater than about 100 degrees Celsius and then rapidly drying. The starch powder has high viscosity at low concentration, is not dispersed or dissolved in cold water, can be solidified by rapid aging, while alpha starch does not have high viscosity at low concentration, is easily dispersed or dissolved in cold water, Can be delayed. Thus, the alpha starch can improve the workability of the coating process. Alpha starch may be, for example, amylopectin. Amylopectin is a poorly soluble component with the removal of soluble amylose, has a network structure, and has the property of forming a soft film. Therefore, amylopectin can have a smoothness that is strong against an external impact. Alpha starch may be used in an amount of about 3% to about 20% by weight based on the total coating composition, and the operability of the coating process when used in this range may be improved.

Maltodextrin can effectively lower the rate of senescence of alpha starch. Maltodextrin has excellent film-forming ability and dryness, has high solubility and low molecular weight, and thus has an advantage of penetrating into the cigarette paper. Since maltodextrin can be dissolved in ethanol, when used with ethanol, the viscosity of the coating composition can be lowered and the binding force between the components of the coating composition can be increased. The maltodextrin may be used in an amount of about 5% to about 40% by weight based on the total coating composition, and film forming ability and dryness can be improved when used in this range.

Depending on the amount of ethanol contained in the coating composition, the solids content of the coating composition can be increased and the viscosity of the alpha starch can be lowered and maintained. Table 1 below shows the viscosity changes of the coating compositions with respect to the content of ethanol based on the total coating composition.

Ethanol content
(weight%) The viscosity (cps) of the coating composition with the elapsed time Immediately after manufacture 4 hours 24 hours 48 hours 0 2,500 8,600 11,500 12,300 5 2,200 5,200 8,100 9,300 10 2,100 3,400 4,400 5,200 15 1,400 2,300 3,400 4,600 20 1,400 1,400 1,400 1,400

Ethanol can also increase the shelf life of the coating composition. Ethanol can improve the drying efficiency of moisture of the coating composition, and ethanol can prevent a decrease in strength due to moisture absorption of the cigarette paper. Ethanol may be used in an amount of about 10% to about 40% by weight based on the entire coating composition, and when used in this range, the viscosity of the coating composition can be effectively maintained and the dryness can be improved. Ethanol may be vaporized in the manufacturing process of the cigarette paper, and may not be included in the coating portion 18.

The coating composition comprises water. For example, water may be used in an amount of about 30% to 80% by weight. Water may be vaporized in the manufacturing process of the cigarette paper, and may not be included in the coating portion 18.

The content of solids in the coating composition may be greater than about 27 to less than about 38 weight percent. When the content of the solid content is more than 27% by weight, the coating composition containing the solid content can satisfy the sufficient burning strength, and it is possible to reduce the generation of the wrinkles of the cigarette and the breakage during the coating process due to the drying failure, . When the content of the solid content is less than 38% by weight, the coating composition containing the solid content within the above range can not uniformly coat the coating composition and reduce scratches on the surface of the cigarette paper.

The weight ratio of the solids content to the ethanol content in the coating composition may be from about 1: 0.25 to about 1: 0.85.

The storage modulus of the coating composition may be about 150-600 dyne / cm < 2 > at room temperature. Within the above range, the surface of the cigarette paper 19 can be coated on the surface of the cigarette paper 19 to reduce the surface energy, so that the coated portion of the cigarette including the low-fogging cigarette paper can be formed. In addition, it becomes a suitable coating composition for an on-line coating process of about 10,000 CPM (ciagrette per minute). In order for the coating composition to be uniformly coated at a process speed of about 10,000 CPM, it is necessary to maintain a proper storage elastic modulus and loss elastic modulus against the mechanical shear strength applied to the coating liquid at the time of coating. Within the storage modulus range of the coating composition, the coating flow phenomenon at high speed is uniform and the surface energy of the coating composition and the coated portion can be uniform. As a result, the target combustion strength and FASE (Free Air Self Extinguish) can be achieved.

The ratio of the loss modulus to the storage modulus of the coating composition of the coating composition (loss modulus / storage modulus) may be about 0.8 to 2.0. Within the above range, the surface of the cigarette paper 19 coated with the surface of the cigarette paper 19 may be reduced to form the coated portion of the cigarette 1 including the low-fogging cigarette paper. It is also a suitable coating composition for an on-line coating process of about 10,000 CPM. When maintaining the ratio of the loss modulus to the storage modulus within the above range, a uniform coating layer and surface energy are secured in the high-speed cigarette manufacturing process, and the target burning strength and FASE (Free Air Self Extinguish) Can be achieved.

The surface energy of the coating composition may be about 25 to 40 mN / m.

Within the above range, the surface of the cigarette paper 19 coated with the surface of the cigarette paper 19 may be reduced to form the coated portion of the cigarette 1 including the low-fogging cigarette paper. It is also a suitable coating composition for an on-line coating process of about 10,000 CPM. In addition, within the surface energy of the coating composition, unevenness of the coating layer due to the difference in surface energy between the base material, the cigarette paper and the coating layer, and the occurrence of separation and separation of the coating layer due to the environment such as humidity and temperature can be reduced .

When the coating composition is applied to the surface of the cigarette paper 19, the coating portion 18 is formed and the surface energy of the paper of the cigarette paper 19 before application is reduced. For example, the surface energy of the coated portion 18 coated with the coating composition on the surface of the cigarette paper 19 can be lowered to about 75 to 85 mN / m.

Ignition strength can be measured based on ISO 12863, ASTM E 2187-04, and 40 cigarettes are placed on 10 sheets of filter paper and the ratio of cigarettes that are not burned to the end of 40 cigarettes it means. The higher the burning intensity, the higher the ratio of tobacco to be turned off in the middle.

The burning intensity of the cigarette 1 according to an embodiment of the present invention may be about 75% or more. Within the above range, it can be spontaneously extinguished by adjusting the ignitability to a sufficiently low level.

Free air self extinguish (FASE) refers to the number of cigarettes that are turned off 3 mm before the tip paper when the cigarette is burned in the Static Burining state. The higher the FASE, the higher the likelihood that the smoldering cigarette will turn off. Therefore, the coating of the low flammability courseware may have a high burning intensity to lower the likelihood of ignition. In addition, the porosity and the air diffusivity of the coating layer can be appropriately adjusted so that the cigarette does not turn off during the smoothing period during the smoking process.

In addition, the free air self extinguishing (FASE) of the cigarette 1 according to an embodiment of the present invention may be about 5 to 50%.

When the FASE is maintained within the above range, the possibility that the cigarette is turned off during smoothing is small, and when it is non-smoking, the flammability can be controlled to be sufficiently low to be spontaneously digested

EXAMPLES Hereinafter, the present invention will be described in more detail with reference to Examples. However, the following Examples are merely examples of the present invention, but the present invention is not limited to the following Examples.

Characterization of Coated Paper and Coating Composition

Each coating composition is prepared by varying the solids content in the coating composition as shown in Table 2 below. Each coating composition contains only alpha corn starch, maltodextrin, ethanol, and water. Next, for each coating composition having a solids content of about 30, 32, and 35 weight percent, the respective static viscosities, the surface energy of the coating composition, the surface energy of the substrate (cigarette paper) coated with the coating composition, The surface energy of the coated portion coated with the coating composition was measured, and the results are shown in Table 3 below.

Solid content (% by weight) Detailed constituents in the solid content Alpha corn starch (wt%) Maltodextrin (% by weight) 27 10.0 17.0 30 11.0 19.0 32 12.0 20.0 35 13.0 22.0 38 14.0 24.0

Too high

Referring to Table 7, it can be seen that in Examples 1 to 3, the ignitability is low at a burning strength of about 75% or more, and the burning strength is increased as the solid content in the coating composition is increased. However, in the case of Comparative Example 2, in which the solid content in the coating composition is about 27%, it is difficult to satisfy the burning strength, the formation of the wrinkles of the cigarette due to the drying failure and the breakage during the coating process may occur and the production speed of the cigarette may be lowered. Also, in the case of Comparative Example 3 in which the solid content in the coating composition is about 38%, the coating portion due to the coating composition may be uneven and some scratches may be generated on the surface of the cigarette paper.

Referring to Table 8, it can be seen that the FASE of Examples 1 to 3 is as good as about 10 to 50%, and the FASE increases as the content of the solid content in the coating composition increases. . However, in the case of Comparative Example 2 in which the solid content in the coating composition is about 27%, it is difficult to satisfy the burning strength, the formation of the wrinkles of the cigarette due to the drying failure and the breakage during the coating process may occur and the production speed of the cigarette may be lowered. Further, in the case of Comparative Example 3 in which the solid content in the coating composition is about 38%, the coating portion due to the coating composition is uneven, the rate of the middle portion is too high, and some scratches may occur on the surface of the cigarette paper.

Flow characteristics rheology properties )

The storage elastic modulus (G '), the loss elastic modulus (G ") and the storage elastic modulus / loss elastic modulus (G' / G") of each coating composition used in Examples 1 to 3 were measured, Respectively.

As a result of the experiment, it can be seen that the storage elastic modulus tends to increase somewhat as the content of the solid content in the coating composition used in Examples 1 to 3 increases, but the ratio of the loss elastic modulus / storage elastic modulus is maintained at about 1.2 to 1.6.

Thus, it can be seen that all of the coating compositions used in Examples 1 to 3 are good in mass coating workability at 10,000 CPM. If the storage elastic modulus is above the above range, scratches and unevenness of the coating layer may occur. If the loss / storage elastic modulus is above the above range, the flowability of the coating solution is increased and penetration of the coating solution into the cigarette paper is increased, have. Therefore, in order for the coating liquid to uniformly coat at a rate of 10,000 CPM, it is necessary to maintain proper storage elastic modulus and loss elastic modulus against the mechanical shear strength applied to the coating liquid during coating.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Of the right.
