Description

Roll paper for non-combustible heating smoking articles, non-combustible heating smoking articles and electrically heated smoking system

The present invention relates to roll paper for non-combustion heating type smoking articles, non-combustion heating type smoking articles, and electric heating type smoking systems.

It is known to heat non-combustible heating smoking articles in the form of tobacco rods containing tobacco shreds to deliver volatile components to users. In non-combustion heating type smoking articles, the tobacco rod wrapped in roll paper is heated, but unlike previous cigarettes, the tobacco rod will not burn and remain after use (after heating).

In the previous cigarettes, the roll paper used to wrap the tobacco shreds, although sometimes attached with a trademark, etc., is generally white (colorless) paper.

Among non-burning and heating type smoking articles, it is known that when the roll paper used for the previous cigarette is used as the roll paper for wrapping tobacco filaments, it may be uncomfortable for the user due to heating during use Discoloration. In contrast to this problem, although there is a method of using a specific colored paper to make the color change less conspicuous, it can be known that it takes extra effort when using white paper with high versatility.

Therefore, in the present invention, it is an object to provide a non-combustible heating type roll paper for smoking articles that does not cause appearance discomfort that may be caused by heating.

In order to solve the above-mentioned problems, the present inventors focused on: by a roll paper having a white portion, the white portion has a specific whiteness before heating and a specific range of color-changing regions after heating, so as to change the uncomfortable color-changing It's less striking.

Paper based on pulp, when heated at a temperature above a certain temperature, will scorch and change color to brown. The reason is that the physical components of the pulp or paper are caused by thermal decomposition, so this cannot be simply prevented. Discoloration. However, it was found that even if the discoloration occurs due to coking, if the original color of the paper and the subsequent discoloration degree can be reduced to a certain range, it is not easy to be recognized as an uncomfortable burnt black feeling.

The inventor found that a mathematical formula is used to represent this visually tolerable area of color change in the degree of discoloration, and found that when the values of L*, a*, b* before and after heating are substituted into the mathematical formula, a specific display will be displayed And use paper with a white portion with a specific whiteness before heating as the roll paper, which can solve the problem of discomfort related to discomfort specific to non-burning heating smoking articles.

Specifically, the present inventors found that using paper having a white portion with an ISO whiteness before heating of 83% or more and a small color difference before and after heating can solve the above-mentioned problem of discoloration.

<Roll paper for non-combustible heating type smoking articles>

In this specification, the "roll paper for non-combustion heating type smoking articles" refers to the roll paper used in the non-combustion heating type smoking articles described later. The following is also simply referred to as the roll paper of the embodiment of the present invention. For the application of the rolled paper according to the embodiment of the present invention, the so-called "non-combustible heating type smoking article" means that it is used to wrap a tobacco rod-containing filler to produce a tobacco rod, or to connect to the tobacco rod for connection It is used to wrap these outer peripheral surfaces.

The roll paper according to the embodiment of the present invention has a white portion, and the white portion is heated at 230° C. for 3 minutes before and after (also referred to as just before and after heating), and L*, a*, and b* are measured respectively before and after heating. The difference between the values (the value after subtracting the value after heating minus the value before heating) is expressed as △L*, △a*, △b*, respectively, and these values are substituted into the following formula (1) to obtain y (Discrimination score) has a value less than 0.62, and the ISO whiteness is 83% or more.

Discrimination score (y) y=-0.18×△L*+0.08×△a*+0.13×△b*-2.36 (1)

If the rolled paper according to the embodiment of the present invention has a white portion where the values of △L*, △a*, and △b* are substituted into the above-mentioned formula (1), the discriminating score shows a value less than 0.62. The values of L*, a*, and b* are not particularly limited.

The white part having the above-mentioned discriminant score may exist on the entire surface of the roll paper in the embodiment of the present invention, or may be a state where it exists at least in a heated part (heating by an electric heating type device described later).

The ISO whiteness can be obtained by the following method.

According to JIS 8148:2001 ISO whiteness (diffused blue light reflectance) measurement method for paper, paperboard and pulp, use whiteness/opacity measuring machine (manufacturer: Murakami Color Technology Research Institute, model: WMS-1) Determination.

Those with a higher L* value before heating (brighter and lighter colors) in the white part tend to have an ISO whiteness of 83% or more. In one form of roll paper, the L* value before heating of the white part may be at least 95%.

As shown in the examples described later, if y (discrimination score) obtained by the above formula (1) is less than 0.62, there will be no appearance discomfort that may occur due to heating. When the y (discrimination score) obtained by the above formula (1) is less than 0, it is possible to more surely include those who will not damage the appearance before and after heating.

In the roll paper of the embodiment of the present invention, each value of L*, a*, and b* before and after heating is measured at 5 points of the white part of the paper as the sample, and a simple average value is used. The measurement object is an arbitrary point on the white part of the paper. However, when there is a character or design such as a trademark on the paper, the part where the white part of the character or trademark does not exist is targeted. Each value of L*, a*, and b* can be measured using a spectrophotometer.

Specifically, a spectrophotometer (manufactured by X-Rite, product name SpectroEye) can be used. The measurement is performed under the conditions of the light source D65, the non-light source filter, and the viewing angle of 2°, one sample is placed on a paper with an ISO whiteness of 92%, and the measurement portion of the spectrophotometer is pressed against it.

The means for obtaining a paper having a white part with a discrimination score obtained by the above formula (1) showing a value less than 0.62 and an ISO whiteness of 83% or more (also referred to as paper having the above characteristics) is not particularly limited. , A generally known method can be used. When the entire surface of the roll paper has a white part with a discriminant score showing less than 0.62 and an ISO whiteness of 83% or more, the roll paper can be manufactured by adjusting the types and contents of pulp and fillers in the paper making stage. Specific examples include increasing the content of fillers described later or avoiding the use of colored materials as much as possible.

On the other hand, when a part of the roll paper has a colored part within a range that does not impair the appearance impression after heating, for example, by printing, a colored part showing a desired hue can be given. The printing method is not particularly limited, and examples thereof include gravure printing and lithography. The colored part refers to the part where the ISO whiteness does not reach 83%.

When a trademark or a partial pattern is added as a colored part to the base paper by printing, the printing surface (printing place) is not regarded as the object of color measurement by a spectrophotometer. In addition, when the colored portion is applied to the roll paper by printing, the area ratio thereof may be 10% or less, preferably 5% or less, and particularly preferably 3% or less. Conversely, in the roll paper of the embodiment of the present invention, the ratio of the area of the white portion may be 90% or more, preferably 95% or more, and particularly preferably 97% or more. On the other hand, when a regular pattern is given as a colored part and does not affect the appearance impression before and after heating, the ratio of the area of the white part may only be 50% or more.

On the surface of the roll paper, at least the heated portion (the portion heated by the electric heating type device) is preferably a discrimination score obtained by the above formula (1) of less than 0.62 and an ISO whiteness of 83% or more. In the surface of the roll paper, by having the portion heated by the electric heating type device described later have the above characteristics, it is possible to prevent the deterioration of the appearance impression after heating.

The basis weight of the base roll paper of the embodiment of the present invention is, for example, usually 20 gsm or more, preferably 25 gsm or more. On the other hand, the basis weight is usually 65 gsm or less, preferably 50 gsm or less, and more preferably 45 gsm or less. The relationship between the basis weight and the content of the filler will be described later.

The thickness of the roll paper having the above characteristics is not particularly limited. From the viewpoint of rigidity, air permeability, and ease of adjustment during papermaking, it is usually 10 μm or more, preferably 20 μm or more, and particularly preferably 30 μm or more. It is 100 μm or less, preferably 75 μm or less, and particularly preferably 50 μm or less.

The roll paper for non-combustible heating type smoking articles may be square or rectangular. When used as roll paper for wrapping tobacco filaments (for making tobacco rods), the length of one side may be about 15 to 70 mm, and the length of the other side may be about 15 to 26.5 mm. The preferred length may be 24mm.

Like the tipping paper, when connecting the tobacco rod and other members adjacent to the tobacco rod for wrapping, the length of one side may be 20 to 60 mm, and the length of the other side may be about 15 to 26.5 mm.

Examples of the roll paper having the above-mentioned characteristics include those having pulp as a main component. In addition to being made from wood pulp such as conifer pulp or broadleaf pulp, it can also be mixed with flax pulp, hemp pulp, sisal pulp, reed, etc., which is generally used in non-wood pulp used in cigarette paper for smoking articles. Get.

For the type of pulp, chemical pulp, wood pulp, chemical wood pulp, thermomechanical pulp, etc. obtained by the sulfate digestion method, acidic or neutral or alkaline sulfite digestion method, sodium salt digestion method, etc. can be used .

In the papermaking step performed by the long-wire paper machine, the rotary-wire paper machine, the round-short composite paper machine, etc., using the above-mentioned pulp, the roll paper is uniformly produced with a uniform texture. In addition, the aforementioned wetting paper strength enhancer may be added as necessary to impart water resistance to the roll paper, or a sizing agent may be added to adjust the printing degree of the roll paper. Furthermore, aluminum sulfate, various anionic, cationic, non-ionic or amphoteric yield enhancers, water drainage enhancers, and paper strength enhancers can be added with additives such as dyes, pH adjusters , Antifoaming agent, spacing control agent, and slime control agent and other paper-making additives.

In addition to the above-mentioned pulp, the rolled paper according to the embodiment of the present invention may contain a filler. The content of the filler may be 10% by weight or more and less than 60% by weight with respect to the total weight of the rolled paper of the embodiment of the present invention, preferably 15 to 45% by weight.

In the roll paper of the embodiment of the present invention, in the preferred basis weight range (25 to 45 gsm), the filler is preferably 15 to 45% by weight.

Furthermore, when the basis weight is 25 gsm or more and 35 gsm or less, the filler is preferably 15 to 45% by weight, and when the basis weight is more than 35 gsm and 45 gsm or less, the filler is preferably 25 to 45% by weight.

Calcium carbonate, titanium dioxide, kaolin and the like can be used as the filler. From the viewpoint of improving taste and whiteness, calcium carbonate is preferably used.

Paper containing this filler usually presents a bright color of white color, which can maintain white for a long time. By containing a large amount of this filler, the ISO whiteness of the roll paper can be set to 83%.

The rolled paper according to the embodiment of the present invention, having a tensile strength measured by the following measuring method of 8 N/15 mm or more, is preferable from the practical viewpoint of using the rolled paper as a non-combustion heating type smoking article.

This tensile strength can be increased by reducing the filler content. Specifically, by making the content of the filler lower than the upper limit of the content of the filler shown in the range of each basis weight exemplified above, the tensile strength can be improved.

<Measurement method of tensile strength>

Paper and board based on P8113: 2006 (ISO1924-2: 1994)-Test method for tensile properties-Part 2: Measured using the Strograph E-L manufactured by Toyo Seiki Co., Ltd. according to the constant speed drawing method.

The opacity of the rolled paper according to the embodiment of the present invention measured by the following measuring method is preferably 60% or more. Opacity can be increased by increasing the filler content in the roll paper. Specifically, by making the content of the filler higher than the lower limit of the content of the filler shown in the range of each basis weight exemplified above, the opacity can be improved.

<Measurement method of opacity>

Opacity is the value measured according to ISO2471 using a whiteness/opacity measuring machine (manufacturer: Murakami Color Technology Research Institute, model: WMS-1). The opacity is a value calculated by the formula: single-sheet visual reflectance coefficient (R0)/intrinsic visual reflectance coefficient (R∞)×100(%). The inherent visual reflectance coefficient (R∞) of this calculation formula is the inherent reflectance coefficient of whiteness when measured under the spectroscopic conditions of an effective wavelength of 457 nm and a half-value width of 44 nm using a predetermined reflectometer and light source.

In order to satisfy the above-mentioned discrimination score, it is preferable that the roll paper of the embodiment of the present invention does not contain the oxidizing agent contained in the previous roll paper for tobacco rod. The roll paper of the embodiment of the present invention can be used as the first roll paper used for the non-combustion heating type smoking article described later, or as the second roll paper.

<Non-combustion heating type smoking articles>

Examples of the non-combustion heating type smoking article of the embodiment of the present invention include those having the structure shown in FIG.

The non-combustion heating type smoking article 10 of FIG. 1 has a filler 11, a tobacco rod portion composed of the first roll paper 12 of the package filler 11, and an end portion opposite to the tobacco rod portion The mouthpiece portion 16; the tobacco rod portion and the mouthpiece portion are connected using another second roll paper 13 (outer layer paper in FIG. 1) that is the same as or different from the roll paper that wraps the filler. In the embodiment of the present invention, even if the first roll paper and the second roll paper are each composed of only one sheet, they will not be burned by heating. If each is composed of only one piece, the cost can be reduced.

At least one of the first roll paper and the second roll paper is the roll paper of the embodiment of the present invention described above. Preferably, at least the first roll of paper is a roll of paper in an embodiment of the present invention. In addition, it is also preferable that both the first roll paper 12 and the second roll paper are the roll paper of the embodiment of the present invention described above.

In the aspect shown in FIG. 1, the mouthpiece portion 16 includes a paper tube portion 14 and a filter portion 15. In addition, the outer layer paper 13 is provided as a second roll paper for connecting these. In FIG. 1, the mouthpiece portion 16 is composed of two sections, but the mouthpiece portion 16 may be composed of a single section or three or more sections. In addition, the section constituting the mouthpiece portion may be constituted to include both the paper tube portion and the filter portion or only one of them.

4.5至

1.0mm的桿。由於填充層之纖維的填充密度高，所以於吸嚐時空氣或霧氣(aerosol)僅流通通道部，幾乎不流通填充層內。非燃燒加熱型吸煙物品中，在欲降低因濾嘴部15中之霧氣成分的過濾所導致之減少時，可縮短濾嘴部15的長度並以中空區段17來取代，此對於增大霧氣成分輸送量而言為有效。由於中空區段17內部的填充層為纖維填充層，所以於使用時從外側接觸的觸感比起紙管部14更接近於濾嘴部，因此帶給使用者的差異感較少。 In FIG. 2, it is described that the mouthpiece portion 16 is composed of three sections. The embodiment of FIG. 2 has a hollow section 17 between the paper tube portion 14 and the filter portion 15 of FIG. 1. The hollow section 17 is composed of a filling layer having one or a plurality of hollow channels and a plugging material covering the filling layer. The filling layer can be constituted, for example, by filling cellulose acetate fibers at a high density and adding 6 to 20% by weight of a plasticizer containing triacetin to the weight of cellulose acetate and hardening the inner diameter. for

4.5 to

1.0mm rod. Due to the high packing density of the fibers of the filling layer, air or mist (aerosol) only circulates through the channel portion during absorption, and hardly circulates in the filling layer. In the non-combustion heating type smoking article, when the reduction due to the filtering of the mist component in the filter portion 15 is to be reduced, the length of the filter portion 15 can be shortened and replaced with a hollow section 17, which increases the mist The amount of component delivery is effective. Since the filling layer inside the hollow section 17 is a fiber filling layer, the touch feeling from the outside is closer to the filter portion than the paper tube portion 14 during use, so that the difference to the user is less.

In the embodiments shown in FIGS. 1 and 2, the length of the non-combustion heating type smoking article 10 in the longitudinal direction is preferably 40 mm to 90 mm, particularly preferably 50 mm to 75 mm, and more preferably 50 mm to 60 mm. In addition, the circumference of the non-burning heating type smoking article is preferably 15 mm to 25 mm, particularly preferably 17 mm to 24 mm, and more preferably 20 mm to 22 mm. In addition, in the embodiment shown in FIG. 2, the length of the tobacco rod portion is 20 mm, the length of the paper tube portion is 20 mm, the length of the hollow section portion is 8 mm, and the length of the filter portion is 7 mm. However, these individual segment lengths can be appropriately changed according to manufacturing suitability, required quality, etc.

The steam containing the mist-generating base material and the tobacco flavor component generated by heating the tobacco rod will cool and liquefy as it passes through the paper tube portion 14 and contacts the air in the paper tube to generate mist.

In addition, the non-burning heating type smoking article 10 may also have a small hole for extracting air from the outside of a part of the second roll paper 13 (outer paper) around the paper tube portion 14 and the coated paper tube portion 14 ( (Not shown in the figure). The presence of the micropores allows air to flow into the paper tube portion 14 from the outside during use, so that the steam containing the mist generating base material and tobacco flavor component generated by heating the tobacco rod and the external Air contact reduces the temperature and liquefies, and mist can be generated more reliably.

The paper tube portion 14 may include, for example, a thick paper processed into a cylindrical shape.

For example, the filter part 15 may use acetate tow as a material. The monofilament fineness and total fineness of the acetate tow are not particularly limited.

In FIG. 1, the filter portion 15 is composed of a single segment, but it may be composed of a plurality of segments. When it is composed of a plurality of sections, for example, the hollow section is arranged on the upstream side, and the section on the downstream side (the end of the user's suction port) is a state in which the suction port section is filled with acetate tow . According to this aspect, the unnecessary loss of the generated mist can be prevented, and at the same time, the appearance of the non-burning heating type smoking article can be improved.

In addition, at the time of manufacturing the filter, adjustment of ventilation resistance or addition of additives (generally known adsorbents, fragrances, fragrance holding materials, etc.) can be appropriately set.

The material of the second roll paper 13 (outer layer paper) is not particularly limited, and a part or all of the roll paper of the embodiment of the present invention may be used. The second roll paper 13 may be, for example, a vinyl acetate-based adhesive that wraps around the tobacco rod, paper tube portion 14, and filter portion 15 and then fixes them.

The tobacco rod system contains tobacco shreds as the filler 11, and the material of the tobacco shreds is not particularly limited, and generally known ones such as laminas or main veins can be used. The content range of the filler in the tobacco rod can be 200 to 400 mg/rod, preferably 250 to 320 mg/rod when the tobacco rod is 22 mm in circumference and 20 mm in length. The moisture content of the filler may be 10 to 15% by weight, preferably 11 to 13% by weight. For this moisture content, it is possible to suppress the occurrence of bleed out during winding, so that the winding suitability during the manufacture of tobacco rods is good.

There is no particular limitation on the size of tobacco shreds used as filler and the method of preparation thereof. For example, one that cuts the dried tobacco leaves to a width of 0.8 to 1.2 mm can be used.

In addition, it can also be used: crush the dried tobacco leaves to an average particle size of about 20 to 200 μm and homogenize it, and then thinly slice this, and cut to a width of 0.8 to 1.2 mm.

In addition, it is also possible to use it as a filler without chopping the above-mentioned sheet processing but by wrinkling.

The filler includes a mist generating base material that generates mist smoke. The type of the base material for generating mist is not particularly limited, and extracted substances from various natural products and/or these constituent components can be selected according to the application. Examples of the mist generating substrate include glycerin, propylene glycol, glycerin triacetate, 1,3-butanediol, and mixtures thereof.

In the production of the non-combustion heating type smoking article of the embodiment of the present invention, the roll paper of the embodiment of the present invention described above can be used. Specifically, a filler containing tobacco shreds and a mist-generating base material can be formed, and then the rolled material of the embodiment of the present invention is used to wrap the shaped filler to obtain a tobacco rod. In addition, by wrapping the tobacco rod and the member constituting the mouthpiece portion by using an outer layer paper (or a roll paper according to an embodiment of the present invention), a non-burning heating type smoking article can be obtained. For winding, a generally known winding device can be used.

In the manufacture of non-combustion heating type smoking articles, by using the roll paper of the embodiment of the present invention as the roll paper and/or outer paper of the tobacco rod, it is possible to provide an appearance that does not impair the appearance after use (after heating) Non-burning and heating type smoking articles.

The non-combustion heating type smoking article 10 according to an embodiment of the present invention includes a filler 11, a tobacco rod portion composed of a roll paper 12 (roll paper according to an embodiment of the present invention), a paper tube portion 14 and a filter portion 15. And a second roll of paper 13 to connect these. In addition, the non-burning heating type smoking article 10 may also have a small hole for extracting air from the outside of a portion of the second roll of paper 13 around the paper tube portion 14 and the coated paper tube portion 14 (not shown) ). The presence of the micropores allows air to flow into the paper tube portion 14 from the outside during use, so that the steam containing the mist generating base material and tobacco flavor component generated by heating the tobacco rod, and the external The air in contact with it reduces the temperature and liquefies, which can generate mist more reliably.

<Electric heating smoking system>

Figure 3 illustrates the same state of the electrically heated smoking system. The electrically-heated smoking system 30 is used in such a manner that the non-combustion-heated smoking article 10 described above is brought into contact with the heat transfer member 25 which is disposed inside the electrically-heated device 20 and is Heater 24 contacts.

The electric heating device 20 has, for example, a battery unit 21 and a control unit 22 inside a resinous body 23.

As described above, the non-combustion heating type smoking article has a filler 11, a tobacco rod portion composed of the first roll paper 12 of the package filler 11, and an end portion opposite to the tobacco rod portion The mouthpiece portion 16; the tobacco rod portion and the mouthpiece portion are connected using another second roll paper that is the same as or different from the roll paper that wraps the filler. The mouthpiece portion 16 of the non-combustion heating type smoking article may be composed of the paper tube portion 14 and the filter portion 15 as shown in FIG. 1, or may be formed on the paper tube portion 14 and the filter portion as shown in FIG. 2 Between 15 there is a hollow section composed of a filling layer 17.

When the non-combustion heating type smoking article is embedded in the electric heating type device, the outer circumferential surface of the tobacco rod and the outer circumferential surface constituted by the second roll of paper (outer paper 13) connecting the tobacco rod and the paper tube portion 14 Part of it is in contact with the heat transfer member 25 inside the electric heating device 20.

The heater 24 inside the electric heating device 20 generates heat by the control performed by the control unit 22. This heat is transferred to the tobacco rod of the non-combustion heating type smoking article via the heat transfer member 25, so that the mist generating base material contained in the filler 11 of the tobacco rod volatilizes together with the flavor component.

By the heating according to the heater member 24, the tobacco rod is heated to approximately 150 to 250°C.

When measuring the above L*, a*, b*, the heating temperature of the roll paper is set to 230° C. and the time is set to 3 minutes. This is based on the premise that the electric heating type smoking system of the embodiment of the present invention is used. And the setter.

The steam containing the mist-generating base material and flavor components generated by heating is atomized inside the paper tube portion 14 by the mechanism described above, and passes through the filter portion 15 of the non-burning heating type smoking article 10 And reach the user's mouth.

[Example]

Hereinafter, the present invention will be described more specifically with examples, but the present invention is not limited to the description of the following examples without exceeding the gist.

<Preparation of paper samples before and after heating>

For the brightness L*, chromaticity a*, and chromaticity b* in the CIELab color system, papers with various values are prepared. As the colored paper, for example, a gravure printing product, a mixed product of unbleached pulp made of white general pulp, and a tobacco sheet made of fine tobacco leaves are prepared. As a completely uncolored paper sample, general outer paper and roll paper using 100% virgin pulp were prepared as controls. All 26 types of paper were prepared.

<heating conditions>

The reheating furnace (product name: Muffle Furnace Model F0410, manufactured by Yamato Scientific) was previously adjusted to 230°C. Open the furnace door and place the paper sample on household aluminum foil (material: aluminum foil thickness: 11 μm), then put it in the reheat furnace and close the furnace door. Quickly perform the aforementioned actions (within 3 seconds) to minimize the temperature drop in the recuperator. Under the heating conditions in this example (reheating furnace temperature setting 230°C, paper sample heating time 3 minutes), the actual paper temperature is set with the reheating furnace after the slowest 1 minute after closing the furnace door The temperature phase is also about 230°C. This system was confirmed by using a color-changing temperature test paper (Thermolabel 5E-170/Thermolabel 5E-210) (manufactured by NOF Corporation).

<Color Difference Measurement>

Using a spectrophotometer (manufactured by X-Rite, product name SpectroEye), the hue of each sample before and after heating was measured. The measurement was performed under the conditions of light source D65, non-light source filter, and viewing angle of 2°. One sample was placed on a paper with an ISO whiteness of 92%, and was pressed against the measurement section of the spectrophotometer above it.

The measurement system was repeated for 5 places and the average value was used for analysis. L*, a*, b* are obtained by direct measurement, and △L*, △a*, △b* are obtained by subtracting the value before heating discoloration from the value after heating discoloration.

There are various evaluation and classification systems in tone evaluation. The CIELab color system is the color system specified by CIE (International Commission on Illumination) and is the basis of JIS Z 8781-4 and ISO 11664-4. This color representation is similar to the human sense and is commonly used, and it is a convenient classification system that can digitize the hue in three dimensions. L* is the axis representing brightness, a* is the axis representing blue to yellow, and b* is the axis representing blue green to red-purple. The higher the L* value, the brighter it is, and the closer a* and b* are to 0, the chroma Lower. For example, L*, a*, b*=100,0,0 is white, and 0,0,0 is black.

<Functional Evaluation>

Let each of the 20 testers look at the paper samples before and after heating, and ask about the staining of the appearance observed from the hue. When the number of the 20 testers who answered that it looks stained and feels uncomfortable is more than 11, The appearance impression of this sample was judged as ×, and when there were less than 11 people, the appearance impression of this sample was judged as ○, and these results were used in the analysis.

<Analysis>

No correlation was observed between the values of ΔL*, Δa*, and Δb* before and after heating and the quality of appearance impression (Figure 4A to Figure 4C).

Since it is impossible to speculate on the advantages and disadvantages of the hue of the heated paper from a simple pattern composed of the difference in hue monomer values, the method of using color difference data to perform discriminant analysis and discriminant analysis to understand the complex factors Relevance. From this result, it is possible to obtain the values of ΔL*, Δa*, and Δb*, which can be used to determine the appearance impression with a high probability of a discrimination rate of 96.2%, as a function of parameters as follows. The P value of the discriminant is less than 0.001, which is statistically highly effective. Generally speaking, if the discriminant rate exceeds 75%, it can be used for speculation, so the discriminant rate of 96.2% means a level that can be almost completely speculated.

Discrimination score y=-0.18×△L*+0.08×△a*+0.13×△b*-2.36 (1)

The discriminant score is above 0.62: × (poor)

Discrimination score less than 0.62: ○ (good)

Formula (1) means that the appearance impression after heating can be almost determined by the △L*, △a*, △b* of the color difference between the paper sample before heating and the paper sample after heating, for example, the lower the △L*, The higher the value of △a* and △b*, the higher the discrimination score. That is, the impression of the paper after heating is in a poor direction.

Figure 5 summarizes the results.

The discriminant analysis system uses two groups of discriminant analysis of Excel Statistics Ver.2.15 multivariate analysis made by Bell Curve Co., Ltd., and analyzes it under the following conditions.

(1) Increase and decrease method P value: input 0.2 to remove 0.2 (2) Deduction of linearly combined variables for analysis

Figure 6 is a graph showing the relationship between △a* and △b* of the paper sample in this survey for more detailed explanation.

Since it cannot be clearly expressed three-dimensionally, the value of ΔL* is simply binarized by -10, and those with a value lower than -10 (it becomes darker) are indicated by black circles or bold X.

Those with poor appearance impressions are indicated by "×" in the evaluation, and the values of △a* and △b* are located at higher places. This means that the color of the reddish purple or yellow or the brown color mixed by heating is greatly changed due to heating. In addition, relatively low ΔL* is also observed in relatively large amounts. That is to say, these samples are visually a group of samples that are close to a dark focus color from a light focus color, and intuitively can also be understood as a group with a poor appearance impression.

In these sample groups, the L* value before heating is relatively high and the a* value and b* value are also low, that is, most of them are bright and have low chroma. It is believed that this bright and light-colored sample will change the brown color due to heating, which will deteriorate the appearance impression.

Conversely, for the "○" samples with good appearance impressions, the values of △a* and △b* are located at lower places. This means that the color is greatly changed toward blue, green, or a mixed blue-green direction due to heating. Even if ΔL* is relatively low, that is, the brightness is low and dark, it is also observed as ○. These sample groups are contrary to the case of X. Before heating, the L* value is relatively low and the a* value and b* value are also high, that is, most of them are dark and have high saturation. It is not easy for samples with this darker hue to change significantly due to heating, which is good for maintaining a good appearance impression.

When viewing the dot plot as a whole, the distribution is a little over a wide range of △a* of ±20 and △b* of ±30, so it can be seen that this experiment is not partial, but covers samples that form changes in various hue .

In the present invention, focusing on the degree of change of the color of the paper before and after heating, and grasping its area as a numerical value, thereby defining an effective range.

It was originally thought that it would be easy to think of this parameterization simply by specifying the hue before heating, but in this statistical method, only the values of L*, a*, b* of the non-color difference paper before heating are used. In, and can not get useful mathematical formulas. Xian acknowledged that this is still because the color components such as pigments or dyes contained in the color have different thermal decomposition behaviors, and the degree of discoloration after heating is also different due to the different color components. Therefore, not only the original color of the paper, but also the way of thinking of the present invention that can correctly estimate the appearance impression by the degree of discoloration is reasonable.

Furthermore, from the above test results, it can be seen that paper having a numerical value of less than 0.62 has little degree of discoloration before and after heating, and does not give an uncomfortable impression to the person performing the observation.

Based on the above, roll paper of the formula shown in Experimental Examples 1 to 18 shown in Table 2 below is further prepared. Specifically, in Experimental Examples 1 to 18, the basis weight and the content of the filler were changed as described in Table 1. In these experimental examples, (wood pulp) was used as the pulp and calcium carbonate (made by Shiraishi Industry Co., Ltd.) was used as the filler. Papermaking is performed by hand, and the method is based on JIS P-8222 "Pulp-Test Preparation Method of Hand Paper". In addition, roll paper for general cigarettes is prepared. The roll paper of Experimental Examples 1 to 18 does not contain a combustion aid. On the other hand, the general cigarette roll contains 1.0% by weight of a combustion aid (sodium citrate).

For these rolls of paper, the values of L*, a*, b* after heating at 230°C for 3 minutes are subtracted from the values of L*, a*, b* previously measured before heating to obtain the △ value , And then substitute each value into the formula for calculating the above-mentioned discriminant score to obtain the discriminant score. The heating method is the same as the above samples 1 to 26.

In addition, the ISO whiteness before heating was measured for these roll papers. Then, according to P8113:2006 (ISO1924-2:1994) described above, the tensile strength was measured using a Strograph E-L manufactured by Toyo Seiki Co., Ltd. as a measuring device. The results are shown in Table 2.

From the results of Table 2, it can be seen that in Experimental Examples 1, 7, and 13 where the ISO whiteness before heating did not reach 83%, the discrimination score was greater than 0.62, and the appearance impression after heating became poor. On the other hand, if the ISO whiteness before heating is 83% or more and the basis weight and filler content are predetermined values, although the color before heating is white, that is, the L* value is high, it is considered to be the appearance impression after heating For those who are easily deteriorated, the appearance impression after heating is not damaged. In addition, the discriminating score of general cigarette roll paper containing a oxidizer is greater than 0.62, and the appearance impression after heating becomes poor. In addition, regardless of the basis weight, when the content of the filler exceeds 45% by weight, a tendency to decrease the tensile strength of the roll paper can be observed. In addition, roll paper with too much filler content deteriorates the high-speed winding characteristics of the tobacco rod.

Then, according to the results in Table 2, according to different basis weights, the content of the filler is plotted on the horizontal axis, and the discriminant score is plotted on the vertical axis to prepare a graph (Figure 7). From the results of Fig. 7, it can be observed that the smaller the basis weight and the greater the content of filler, the smaller the tendency of the discrimination score.

Next, for the results of Table 2, in order to more easily understand the relationship between the filler content and basis weight and the discrimination score, Table 3 is summarized as shown below.

According to the descriptions in Figure 7 and Table 3, from the viewpoint of appearance impression, it can be seen that when the basis weight of the rolled paper is 25 gsm or more and 35 gsm or less, the filler is preferably 15 to 45% by weight, and the basis weight exceeds 35 gsm and is When it is 45 gsm or less, the filler is preferably 25 to 45% by weight. Within the range of the above basis weights, when the content of the filler is below each lower limit value, the opacity is small, and when used as a roll paper, the tobacco thread of the content tends to be seen through. In addition, it can be seen that even if the basis weight and the content of the filler are within the above-mentioned ranges, those containing a oxidizer are not good from the viewpoint of appearance impression.
