Description

  The present invention relates to a method for manufacturing toilet paper, a toilet roll in which a belt-shaped toilet paper is wound around a paper tube, and a method for manufacturing the toilet roll.

  Conventionally, it has been proposed to apply a deodorant to a toilet roll for the purpose of deodorizing the toilet space. For example, a method of adding a deodorant to a tail seal paste that bonds the end of the roll of toilet paper, a method of applying a deodorant to the inner surface of a paper tube, and the like have been proposed. However, the former has a problem in the sustainability of the deodorizing effect because the deodorant imparting portion is used at the same time as the start of use. In the latter case, the position where the deodorant is applied is a limited part of a paper tube, so there is not enough opportunity to contact the odor component with the deodorant, and further improvement of the deodorant function is required. It was.

  On the other hand, it is conceivable to add a deodorant to the toilet paper constituting the toilet roll. If a deodorant can be given to toilet paper, the contact opportunity with an odor component will improve markedly.

  However, since toilet paper directly touches the skin when used, some consumers dislike that the deodorant touches the skin when used. Further, since the amount of deodorant applied is smaller than that of a moisturizer or the like, it is difficult to uniformly apply an appropriate amount over the entire surface of the toilet paper. Furthermore, when applied to the entire surface, the texture of the toilet paper may be reduced.

  In addition, some deodorizers have an excellent deodorizing effect against main malodorous components of toilet spaces such as ammonia such as organic acids, but such acids are iron in the toilet roll manufacturing equipment. Rust the material. This can be prevented to some extent by changing the iron member in the manufacturing apparatus to one made of stainless steel or chrome plating, or increasing the frequency of cleaning, but it is very expensive and laborious.

  As described above, it has been difficult to apply a deodorant to toilet paper to the extent that a sufficient deodorizing effect is exhibited.

  Embodiments of the present invention will be described below with reference to FIGS. However, the present invention is not limited to this embodiment.

[Manufacturing method of toilet roll and toilet paper]
An example of a method for manufacturing a toilet roll and toilet paper according to an embodiment of the present invention will be described with particular reference to FIGS. However, the method for producing the toilet roll and toilet paper of the present invention is not necessarily limited to this method. In addition, the manufacturing method of toilet paper is demonstrated suitably in explaining the manufacturing method of a toilet roll.
As shown in FIG. 1, the method for manufacturing a toilet roll according to this embodiment includes a paper tube forming step (A) for manufacturing a long paper tube 30, and rolls toilet paper around the long paper tube and logs it. A log forming step (B) to be manufactured and a log cutting step (C) for cutting the log into individual toilet rolls are provided.

(Paper tube forming step (A))
In the paper tube forming process of the present embodiment, as shown in FIG. 1A and FIG. 2, one of the two strip-shaped paper tube base papers 31 and 32 fed out from the original rolls 31A and 32A. Adhesive glue 44 is applied to one side of the tube base paper 31 by a gluing roll 51, and the other paper tube base paper 32 is partially overlapped in the width direction on the surface of the one paper tube base paper 31, and the other paper tube The surface of the base paper 32 that does not contact the gluing surface is the surface facing the mandrel shaft 52, that is, the surface that becomes the inner surface of the paper tube, and the paper tube base papers 31 and 32 are spirally wound around the mandrel shaft 52 to continuously form a cylindrical portion. 3 and the cylindrical portion 3 is cut by a cutter 58 with a width more than a multiple of the toilet roll to form a long spiral paper tube 30 (also referred to as a spiral paper tube). This spiral paper tube has a two-layer laminated structure in which one paper tube base paper 31 is on the outer surface side of the paper tube and the other paper tube base paper 32 is on the inner surface side of the paper tube. In this embodiment, two paper tube base papers 31 and 32 are spirally wound. However, a long paper tube may be formed by spirally winding three or more paper tube base papers. Further, in the present invention, a flat paper tube can be used instead of the spiral paper tube.

Although the application amount of the adhesive paste 44 to the paper tube base paper 31 is not particularly limited, it is about 8.0 to 80 g / m ² immediately after application. Moreover, the adhesive paste 44 can use the thing for well-known paper tubes, and can illustrate an acrylic adhesive, a hot-melt-adhesive, a starch paste, PVA (polyvinyl alcohol), etc.

  In the form shown in the drawing, each of the paper tube base papers 31 and 32 is wound around the mandrel shaft 52 by a flat belt 54 wound between a pair of pulleys 53 and 53 and a cylindrical portion located at a predetermined portion on the mandrel shaft 52. The paper tube base papers 31 and 32 are drawn at a predetermined angle with respect to the axis of the mandrel shaft 52 by the rotation, and are wound spirally. In the illustrated example, a pair of pulleys 53, 53 are arranged and rotational force is given to the cylindrical portion 3 by two flat belts 54, 54. However, a cylindrical shape is formed by a pair of pulleys and a flat belt. You may make it give rotational force to a part. Although not shown, the paper tube base papers 31 and 32 can be wound around the mandrel shaft 52 even if a roll is applied to the cylindrical portion 3 instead of the flat belt 54 to apply a rotational force.

  After the long paper tube 30 is formed in this way, the long paper tube 30 is supplied to the conveyor 55, and the winder in the next log forming step (B) is continuously or intermittently performed through an appropriate conveyance path. Supply to X2.

(Log formation process (B))
In parallel with or after the manufacture of the long paper tube 30, the log 75 is manufactured by the winder X2 in the log forming step ((B) in FIG. 1). Note that the log 75 is a toilet that is a final product. It is an intermediate product that has the same diameter as the roll and has a width that is multiple times the width of the final product.

  The log 75 is formed by setting the long paper tube 30 manufactured in the paper tube forming step (A) to the winding portion 85 of the winder X2, and a toilet having substantially the same width or slightly narrower than that. The paper 7 is wound around.

  In this embodiment, the toilet paper 7 wound around the long paper tube 30 is continuously formed by laminating a plurality of toilet paper base sheets 71A and 71B in the winder X2. In this embodiment, as shown in FIGS. 1 and 3 to 5, a deodorant is applied in the process. In the present embodiment, when applying the deodorant while forming the toilet paper 7, the toilet paper base papers 71A and 71B are appropriately controlled from the plurality of raw rolls 70A and 70B wound around the toilet paper base papers 71A and 71B. The embossing rolls 21A and 21B, each of which is provided with a plurality of embossing projections corresponding to the embossed shape on the surface, and receiving rolls 22A for receiving the embossing rolls 21A and 21B. , 22B are guided to the embossing devices 20A, 20B, and the toilet paper bases 71A, 71B are passed between the embossing rolls 21A, 21B and the receiving rolls 22A, 22B to the respective toilet paper bases 71A, 71B. Give emboss separately To so that.

  When embossing is applied, first, toilet paper base sheets 71A and 71B are wound around receiving rolls 22A and 22B, and the embossing is provided between embossing rolls 21A and 21B in the process of transporting the receiving rolls 22A and 22B. After the embossing is applied, the toilet paper base sheets 71A and 71B are conveyed downstream in a state of being wound around the embossing rolls 21A and 21B.

  The transfer roll 25A, which is disposed so that only the tops of the embossing convex portions of the embossing rolls 21A, 21B are in contact with the embossing rolls 21A, 21B except for the portions where the toilet paper base papers 71A, 71B are wound around the embossing rolls 21A, 21B. By 25B, the deodorizer liquid containing a deodorizer is provided only to the top part of the embossing convex part. Since the embossing rolls 21A and 21B are rotating, the embossing projections to which the deodorant is applied are moved between the receiving rolls 22A and 22B and are sent to the receiving rolls 22A and 22B. Embossing and deodorant are simultaneously applied to the paper base papers 71A and 71B. That is, in this embodiment, a deodorizing agent is applied to the tops of the embossing projections of the embossing rolls 21A and 21B prior to contact with the toilet paper base sheets 71A and 71B by roll transfer. A deodorant is applied to the toilet paper bases 71A and 71B. If it does in this way, a deodorizer will be given only to crevice bottom position 26a, 26b corresponding to embossing convex part top 27A, 27B of toilet paper base paper 71A, 71B. In FIG. 4, the deodorant application positions are indicated by reference numerals 27A and 27B.

  3 and 4, the embossing rolls 21A and 21B transfer the deodorant to the toilet paper bases 71A and 71B. However, as shown in FIG. 5, one toilet paper base paper is used. Only the embossing apparatus 20A related to 71A may be provided with the roll transfer equipment 25A, and the deodorizer may be applied only to the toilet paper base 71A via the one embossing roll 20A.

  The toilet paper bases 71A and 71B to which the deodorant is thus applied are then separated from the embossing rolls 21A and 21B, and the surface to which the deodorant is applied is separated from the other raw roll 70A (70B). ), The toilet paper base sheet 71A (71B) to which the deodorant is applied by the other embossing apparatus 20A (20B) and laminated with the deodorizer application surface facing each other, and the deodorant is applied. 7

  In the illustrated form, the toilet paper base 71B separated from one embossing roll 21B is guided to the marriage roll 23 arranged adjacent to the other embossing roll 21A, and laminated and integrated on the marriage roll 23. Yes. However, the present invention is not limited to the illustrated form, and the embossing rolls 21A and 21B are arranged close to each other so that the peripheral surfaces thereof face each other, and the toilet paper base sheets 71A and 71B are provided at positions where the peripheral surfaces of the embossing rolls 21A and 21B face each other. The deodorant application surface may be laminated and integrated.

  Regarding the lamination and integration, as shown in FIG. 5, in particular, the top portions 26A and 26B of the embossed convex portions of the toilet paper base papers 71A and 71B are face-to-face and laminated in a so-called “Tip To Tip” form. Although not shown in the drawing, the embossed convex portions may be stacked in a so-called “Nested” form in which the top portions of the embossed convex portions do not face each other. These can be implemented by selecting an emboss pattern for “Tip To Tip” and “Nested”.

  Moreover, in the form shown in figure, when toilet paper base paper 71A, 71B is conveyed on embossing roll 21A, 21B as a preferable form, it arrange | positions so that it may touch only the top part of the embossing convex part of embossing roll 21A, 21B. The laminated paste is applied to the surfaces of the toilet paper base sheets 71A and 71B by the laminated paste transfer roll 28A. Since the toilet paper bases 71A and 71B are arranged on the surface of the embossing roll in a state of being deformed according to the surface irregularities of the embossing rolls 21A and 21B by pressing at the time of embossing, in this way, the toilet paper base paper Laminate paste is applied only to the positions of the embossed convex top portions of 71A and 71B. When laminate glue is applied in this way, when laminated as shown in FIG. 4, each toilet paper base paper is laminated and integrated with the laminate glue arranged on the top of the embossed convex portion. Thus, ply peeling is prevented. However, in the present invention, it is not always necessary to bond the laminate glue and each toilet paper base paper.

  The illustrated form shows a process in which one toilet paper base 71A, 71B is fed out from two rolls 70A, 70B and laminated to form a toilet paper 7 having a two-ply structure. The toilet paper bases 71A and 71B are not limited to a single sheet. For example, a plurality of stacked toilet paper sheets may be fed out from a raw roll obtained by winding a pre-laminated sheet, or a plurality of stacked toilet paper sheets may be stacked just before the embossing device. Also good. Therefore, the toilet paper of the present invention is not limited to 2 plies and can be 3 plies or more. Furthermore, in the case of a multi-ply structure, it is not necessary for each ply to have the same basis weight or physical properties. Moreover, in the form of illustration, after each toilet paper base paper is unwound from each raw fabric roll, it is configured so as to be peeled again immediately before the embossing devices 20A and 20B after being laminated once by the overlapping portion 78. It is not always necessary to configure the conveyance path in this way. However, this is desirable because the transport path is simplified. Further, in the present embodiment, embossing and deodorizing agent are applied to each toilet paper base fed from each raw roll, but only one embossing device is used as one toilet paper base paper. Only embossing and deodorizing agent may be added.

On the other hand, it is desirable for the toilet paper 7 according to the present embodiment to have a basis weight of 11.0 to 25.0 g / m ² per ply. If it is this range, the softness and water absorption at the time of use can be ensured. Moreover, the toilet paper 7 which concerns on this embodiment contains 90% or more of pulp fibers, Preferably it is 98% or more, More preferably, it is 100%. As the pulp fiber, LBKP (hardwood kraft pulp) and NBKP (conifer kraft pulp) are most preferable, and are particularly composed of LBKP and NBKP, and the blending ratio of LBKP is 50% or more, preferably 70% or more. Good.

  Here, as the embossing imparting devices 20A and 20B according to the present embodiment, it is desirable that the embossing roll is metallic and the receiving roll is elastic with a surface made of rubber or the like. It is a so-called steel rubber type. The combination of the metal embossing roll and the surface elastic receiving roll is preferable because problems such as a problem of adjusting the clearance of the roll and an easy adjustment of the appearance of the embossing in the width direction are unlikely to occur. In the present embodiment, the linear pressure between the rolls may be appropriately adjusted according to the embossing pattern and the amount of deodorant applied. In addition, when using a metal embossing roll, even if a deodorizer reacts with a metal, in this invention, the embossing roll can respond only by washing | cleaning. Since the embossing roll is appropriately washed, there is almost no increase in labor during production. Of course, this problem does not occur if the embossing roll is made of chrome plating or stainless steel having excellent corrosion resistance.

  Moreover, roll transfer equipment 25A, 25B which concerns on this embodiment gives a deodorizer to the top part of the embossing convex part of an embossing roll via an applicator roll. Moreover, a deodorizer can also be provided to the top part of the embossing convex part of an embossing roll via a printing plate roll. The method for applying the deodorant to the applicator roll and printing plate roll is not particularly limited. Deodorant is picked up directly from the deodorant liquid reservoir to the anilox roll, and the amount of application is adjusted by squeezing the deodorant with the roll. The deodorizer is applied to the printing plate roll via the fountain roll or anilox roll A method of applying a deodorant to the anilox roll in a doctor chamber type can be employed. Further, a flexo printing method or a gravure printing method may be used. In the illustrated form, a deodorant is applied to the anilox roll in a doctor chamber manner, and an appropriate amount of the deodorant is applied from the anilox roll to the applicator roll.

On the other hand, the specific emboss pattern, the emboss depth, the emboss density, the shape of each unit emboss constituting the emboss, and the emboss application area according to the present embodiment are not limited. It can be determined as appropriate in consideration of the effectiveness of the deodorant, the properties of the deodorant solution, the amount of the deodorant, the design by embossing, the bulkiness, and the softness. If a preferable example is shown, the emboss density of 30-100 pieces / cm < ² > and the emboss depth of 0.2-2.0 mm were given to the whole paper surface, the form of what is called a micro emboss, 0.1-25 pieces / emboss density / It is an embossing form also called macro embossing or design embossing given to draw a pattern with cm ² and an embossing depth of 0.3 to 2.5 mm. Among these, embossing, which is also called macro embossing or design embossing, is particularly desirable because it has a wide apex and a large amount of deodorant can be applied, and an effect of improving the design can be obtained.

In particular, when the deodorant may corrode the metal member of the facility, the embossing depth is preferably 0.5 mm or more. A more preferable range is 0.6 mm to 1.8 mm, and a particularly preferable range is 0.8 mm to 1.5 mm. The deeper the embossing, the harder the deodorant comes into contact with the equipment members. However, when the embossing is excessively deep, the touch becomes worse. Further, the emboss density is preferably 8.0 pieces / cm ^{2 to} 60 pieces / cm ² , and more preferably 15 pieces / cm ² to 40 pieces / cm ² . Furthermore, the area of one convex part top part is 0.7-2.0 mm < ² > in the more preferable range 0.4-3.0 mm < ² >. If it is this range, it will be hard to be crushed and it will become difficult for a deodorizer to contact an installation member.

  On the other hand, in the present embodiment, when the deodorant is applied, a suitable deodorant is mixed with a solvent, an adhesive, an ink, or the like for fixing the toilet paper base paper, and a liquid state suitable for application or It can be applied as a slurry-like deodorant liquid. The content of the deodorant in the deodorant liquid is desirably 0.5 to 30% by weight as a solid component. If it is this range, it can fully provide to toilet paper 71A, 71B via an embossing convex part. Examples of the solvent include water and alcohols, ethylene glycol, propylene glycol, butylene glycol, isopropyl alcohol, and the like, and the adhesive can be selected within a range that does not interfere with the effect of the deodorant, such as carboxymethyl cellulose, Examples thereof include polyvinyl alcohol and starch.

  Deodorants according to the present invention include polyphenol-based deodorants, amphoteric surfactants, citric acid, graft polymer-based deodorants, betaine compound-based deodorants, essential oils extracted from cedar, cypress, etc. Examples include titanium, aluminum dioxide, natural zeolite, synthetic zeolite, activated clay, molecular sieve, silica gel, Otani stone, calcium oxide, magnesium oxide, barley stone, activated carbon, cyclodextrin, zirconium compound, copper compound, ion exchange resin and the like. These can be used alone or in combination of two or more.

The amount of the deodorant applied to the toilet paper bases 71A and 71B can be appropriately changed depending on the type of the deodorant. If it is the said polyphenol type deodorizer, it is 0.0001-1g / m < ² > by the solid content amount of an active ingredient, Preferably it is 0.003-0.5g / m < ² >.

  The polyphenol-based deodorant contains polyphenols extracted from plants such as teacups and grapes and processed products of plants, and derivatives of the polyphenols as active ingredients. Although it has a high deodorizing function with respect to ammonia as one of the components, it is suitable for use in the method for producing a toilet roll according to the present invention because it oxidizes iron.

Among polyphenol-based deodorants, there are those having reactivity to hydrogen sulfide, methyl mercaptan, and trimethylamine in addition to ammonia and having a deodorizing function. Of course, the polyphenol-based deodorants used in the present invention May be such. The polyphenol deodorant is not limited to either one of polyphenol or polyphenol derivative, and both may be included. Also, it may be a mixture of several types of polyphenols and polyphenol derivatives. Among polyphenol deodorants, tannin and its derivatives are particularly desirable. Tannin and tannin derivatives are excellent in deodorizing function because they have a large molecular weight and a large number of phenolic hydroxyl groups. However, tannin and tannin derivatives are particularly desirable as the polyphenolic deodorant used in the present invention because iron is easily oxidized by tannic acid. Among the tannins, cocoon tannin derived from cocoon has a very large molecular weight and is extremely excellent in the deodorizing effect. Therefore, the polyphenol deodorant should contain at least one of this tannin and cocoon tannin derivatives. It is good to do. Suitable application amount in the case of persimmon tannin, as described above, 0.0001~1g / m ² by solid content, preferably 0.003~0.5g / m ^2.

Further, a laminate glue to impart by laminating glue transfer roll 28A may be selected within a range which does not impair the effect of the deodorant, for example, carboxymethylcellulose, polyvinyl alcohol, starch and the like. In the case where the laminate paste is not used, it is desirable that the deodorant can be applied to the toilet paper without using an adhesive. If neither an adhesive nor a deodorant is used, the toilet paper is not hardened by the adhesive, and the toilet paper becomes softer.

  The above-described deodorant application mode of the present embodiment is performed in a series of flow of the log manufacturing process in the winder X2, and therefore does not reduce the productivity of the toilet roll.

  In addition, the deodorizer application surface of the toilet paper base paper 71A, 71B is constituted by the winder X2 after the deodorizer is applied to each toilet paper base paper 71A, 71B until it is laminated and used as the toilet paper 7. It can be positioned on the inner surface of the toilet paper 7 without contacting the guide roll or the like. Therefore, even if the deodorant has a certain reactivity with metals such as iron, there is no risk of oxidizing, corroding, discoloring or damaging the metal parts of the equipment during the deodorant application process. . Of course, the trouble of cleaning the equipment due to the adhering deodorant is also reduced.

  In addition, since the deodorant is applied through the embossing convex portion, for example, it is a deodorant that significantly reduces the texture of the toilet paper when applied to the entire surface by printing, or a powder system Even if it is a deodorant that requires a binder component to adhere to the paper surface, such as a deodorant, and it is difficult to uniformly apply a small amount evenly by printing etc. to the entire paper surface, Without being reduced, it can be dispersed and applied uniformly over the entire surface.

  In addition, as can be understood from FIG. 4B, the deodorant is applied to the bottom position of the recess recessed from the substantial surface of the toilet paper 7 in the toilet paper to be formed. In the example of illustration, what was given to the lamination | stacking outer surface side of the recessed part bottom 26a, 26b corresponding to embossing convex part 26A, 26B is illustrated, but even if it arrange | positions so that a deodorizer may osmose | permeate into a recessed part bottom Good. Since the deodorant is positioned at this position, the deodorant contacts a member constituting the winder such as a guide roll in the transport process until the toilet paper 7 is wound around the long paper tube 30 after lamination. Is minimized. For this reason, even if the deodorant has a reactivity with a metal such as iron, such as a polyphenol-based deodorant, the metal member such as a guide roll is oxidized, corroded, or discolored during the conveyance process. Or the risk of injury. Of course, the trouble of cleaning the equipment due to the adhering deodorant is also reduced. Moreover, if it is the provision position of the said deodorant, when using the toilet paper 7 as a toilet roll after this, a deodorant becomes difficult to touch skin at the time of use.

  After the toilet paper base papers 71A and 71B are laminated to form the toilet paper 7 as described above, in this embodiment, the perforation line is formed by the perforation line forming device 82, and thereafter, in the winding unit 85 A two-ply log is formed by wrapping around a long paper tube 30. However, in the present invention, it is not always necessary to provide the perforation line forming device and the perforation line. Further, in the present embodiment, although not shown, a known contact embossing device may be provided before the perforation line applying device 82 to provide the contact embossing.

<Log cutting process (C)>
As described above, when the log 75 in which the toilet paper 7 with the deodorant applied to the inner surface of the laminate is wound around the long paper tube 30 is manufactured, as shown in FIG. The accumulator X3 is moved to the subsequent log cutter facility X4 while stocking a plurality. Then, as shown in FIG. 1C in particular, the log 75 is cut into a product width by a known log cutter 91 to obtain individual toilet rolls 10, 10,... As shown in FIG. Since the log 75 according to the present embodiment has no deodorant exposed on the surface, the deodorant may be used in the processes after the log formation even if a deodorant that may damage the metal is used as described above. There is no risk of damaging the production equipment.

  The toilet roll 10 thus formed has the embossing aspect and toilet paper advantages described in the above-mentioned log forming step, and also when the toilet paper is pulled out from the toilet roll and used thereafter. Deodorant is hard to touch the skin. When the toilet roll 10 is used, every time the toilet paper is used, a new toilet paper is exposed on the peripheral surface of the toilet roll. As a result, the deodorizing effect is excellent in sustainability.

[Toilet roll]
Next, an embodiment of a toilet roll according to the present invention will be described with reference to FIGS. The toilet roll 10 according to the present embodiment is one in which a long toilet paper 12 is wound around a paper tube 11 and a deodorant is applied to the toilet paper 12. The toilet roll 10 according to the present embodiment can be manufactured by the manufacturing method described in the column of the manufacturing method of the toilet roll and toilet paper. The structure of the toilet paper base paper, the material / physical properties of the toilet paper, and other toilet paper structures may be the same as those described in the section of the toilet roll and toilet paper manufacturing method.

The toilet paper 12 of the present embodiment has a ply structure in which a plurality of toilet paper base papers 13 are laminated, and in particular, an emboss 14 is provided. And the thing to which embossing is given among toilet paper base paper 13 which constitutes a ply is laminated so that it may be located in the lamination inner surface side of the embossing convex part top part 14A. Further, a deodorant 15 containing polyphenol as an active ingredient is applied to the bottom 14B of the concave portion corresponding to the embossed convex top portion 14A of the toilet paper base 13 to which embossing is applied. The application amount of the active ingredient is 0.0001 to 1.0 g / m ^{2 as a} solid ingredient.

  This toilet roll 10 has a width L1 of 100 to 115 mm, a diameter L2 of 100 to 120 mm, a winding length (total length of toilet paper) of 18 to 70 m, and a paper tube inner diameter L3 of 35 to 50 mm. Is desirable. A paper holder for a general toilet roll can be used with this size, and the length of the toilet paper 12 is sufficient.

The toilet paper 12 according to the present invention preferably has a paper thickness of 100 to 350 μm and a rice basis weight of 11.0 to 25.0 g / m ² per ply. If it is this range, the softness and water absorption at the time of use can be ensured. In addition, the tsubo in accordance with the present invention is based on the tsubo tsubo measurement method of JIS P 8124 (1998), and the paper thickness is the same after the humidity is sufficiently adjusted under the conditions of JIS P 8111 (1998). The average value measured five times using a dial thickness gauge (thickness measuring instrument) “PEACOCK G type” (manufactured by Ozaki Seisakusho) under the conditions. Note that the paper thickness is measured for a plurality of plies as it is.

  The toilet paper 12 according to the present embodiment includes 90% or more of pulp fibers, preferably 98% or more, and more preferably 100%. As the pulp fiber, LBKP (hardwood kraft pulp) and NBKP (conifer kraft pulp) are most preferable, and are particularly composed of LBKP and NBKP, and the blending ratio of LBKP is 50% or more, preferably 70% or more. Good.

  In the toilet roll 10 according to the present embodiment, since the deodorant is applied to the toilet paper 12, the deodorant is positioned on the peripheral surface 12A occupying a wide range of the exposed portion of the toilet roll 10. Therefore, the deodorizing effect is excellent because the chance of contact with malodorous components in the toilet space is increased as compared with the case where the deodorant is applied only to a narrow range such as the paper tube 11. In addition, the toilet roll 10 which concerns on this invention does not deny that the deodorizer is provided to the paper tube.

  Moreover, the toilet roll 10 of this embodiment exists in the position in which the deodorizer 15 was recessed from the substantial surface of toilet paper. That is, it exists in the recessed part bottom 14B corresponding to an embossing convex part. For this reason, a deodorant is hard to touch skin at the time of use. Furthermore, since the new toilet paper 12 will be exposed to the surrounding surface 12A of a toilet roll whenever the toilet paper 12 is used for the toilet roll 10 of this embodiment, a new deodorant is also added to the periphery each time. Since it comes to be positioned on the surface, it has excellent deodorizing effect.

  Moreover, since the toilet roll 10 of this embodiment can be manufactured with the manufacturing method demonstrated in the column of the manufacturing method of said toilet roll and toilet paper, it also has the manufacture advantage of the said description.
