Description

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

  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 adheres 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, since the position where the deodorant is applied is a limited part called a paper tube, the opportunity for contact between the odor component and the deodorant is not sufficient, and further improvement of the deodorant function is required. .

  Then, it is possible to give a deodorant to the toilet paper which comprises a 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. For this reason, when applying a deodorant to toilet paper in a toilet roll, it is desirable to provide a deodorant in the position which a user does not touch at the time of use.

  In addition, as a method of applying a deodorant to toilet paper, since toilet paper is provided with a moisturizer and the like by roll transfer, the deodorant is applied using a roll transfer facility for the moisturizer. It is conceivable to apply a chemical solution containing it to toilet paper base paper.

  However, the deodorant is effective in a small amount as compared with the humectant and is expensive, and therefore the amount of the chemical solution to be applied tends to be small, and it is difficult to manage the low amount of the roll transfer. In addition, the deodorant may reduce the texture of the paper, and this risk increases when the deodorant is applied to the paper surface with a coating amount capable of roll transfer.

  In addition, some deodorizers have an excellent deodorizing effect on main odor 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.

  Thus, there existed various difficult problems regarding efficiently producing toilet paper and toilet roll to which a deodorant having a high deodorizing effect was applied.

  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 paper and toilet roll]
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. 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 the present embodiment includes a paper tube forming step (A) for manufacturing a long paper tube 30, and a log 75 in which toilet paper is wound around the long paper tube. A log forming step (B) for manufacturing the log and a log cutting step (C) for cutting the log into individual toilet rolls 10.

(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 the 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 base paper is overlapped. The surface that does not contact the gluing surface of 32 is the surface facing the mandrel shaft 52, that is, the surface that becomes the inner surface of the paper tube, and the respective paper tube base papers 31 and 32 are spirally wound around the mandrel shaft 52 to continuously form the cylindrical portion 3. The cylindrical portion 3 is cut with a cutter 58 at 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, the two paper tube base papers 31 and 32 are spirally wound. However, one or three or more paper tube base papers may be spirally wound to form a long paper tube. . 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). The log 75 is an intermediate product that is the same diameter as the toilet roll that is the final product and has a width that is a multiple of 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 winding the toilet paper 7. 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.

  Here, in this embodiment, as shown in FIGS. 1 and 3 to 5, the log forming process includes an embossing process, and the deodorizer is applied in the embossing process. That is, in the present embodiment, when applying the deodorant while forming the toilet paper 7, the toilet paper base papers 71A and 71B are appropriately used from the plurality of raw rolls 70A and 70B wound around the toilet paper base papers 71A and 71B. The toilet paper bases 71A and 71B are separately fed out at a speed of 5 mm, and the embossing rolls 21A and 21B each having a plurality of embossing projections corresponding to the embossed shape are formed on the surface, and the embossing rolls 21A and 21B are received. Each of the toilet paper bases 71A, 71A, 71B is guided to the embossing devices 20A, 20B composed of the rolls 22A, 22B, and the toilet paper bases 71A, 71B are passed between the embossing rolls 21A, 21B and the receiving rolls 22A, 22B. Separately on 71B A scan so as to grant.

  Particularly in the present embodiment, when embossing is applied, first, toilet paper base sheets 71A and 71B are wound around the embossing rolls 21A and 21B, and conveyed between the embossing rolls 21A and 21B, between the receiving rolls 22A and 22B. Then, the embosses 26A and 26B are applied, and after the embossing, the toilet paper base sheets 71A and 71B are conveyed downstream in a state of being wound around the receiving rolls 22A and 22B.

  And in this embodiment, in the part where the toilet paper base paper 71A, 71B of the embossing rolls 21A, 21B is not wound, the deodorizer is applied from the spray coating devices 25A, 25B to the surfaces of the embossing rolls 21A, 21B. The chemical | medical solution 90 containing is sprayed and the chemical | medical solution containing a deodorizing agent is provided to the surrounding surface of embossing roll 21A, 21B. Since the embossing rolls 21A and 21B are rotating, the portion to which the chemical liquid containing the deodorant is moved to a position in contact with the toilet paper base paper 71A and 71B. In contrast, a chemical solution containing a deodorant is transferred to the contact surface.

  Thus, in this embodiment, prior to contact with the toilet paper base papers 71A and 71B, a chemical solution containing a deodorant is applied to the surfaces of the embossing rolls 21A and 21B by the spray application devices 25A and 25B. The deodorizer is applied to the toilet paper base sheets 71A and 71B when the toilet paper base sheets 71A and 71B are in contact with the embossing rolls 21A and 21B and while they are in contact with the embossing rolls 21A and 21B.

  3 and 4, the embossing rolls 21A and 21B are configured to apply a deodorant to the toilet paper base sheets 71A and 71B. As shown in FIG. Only the embossing device 20A related to the paper base paper 71A may be provided with a spray coating device, and the deodorant may be applied only to one toilet paper base paper 71A via the one embossing roll 22A.

  The toilet paper bases 71A and 71B thus provided with the deodorant are separated from the receiving rolls 22A and 22B, and the surface on which the chemical solution containing the deodorant is transferred is transferred to the other roll 70A ( 70B), the toilet paper base paper 71A (71B) to which the deodorant is applied by the other embossing device 20A (20B) is laminated with the deodorant application surface facing, and the deodorant is placed on the inner surface 7x of the laminate. The applied toilet paper 7 is used (in FIG. 4, the deodorant-applied portion is indicated by reference numeral 17).

  In the illustrated embodiment, the toilet paper base 71B separated from one receiving roll 22B is guided to the marriage roll 23 arranged adjacent to the other embossing roll 21A, and laminated and integrated on the marriage roll 23. However, the stacking process is not limited to the illustrated form, and the receiving rolls 22A and 22B are arranged close to each other so that the circumferential surfaces thereof face each other, and the circumferential surfaces of the respective receiving rolls 22A and 22B face each other. In FIG. 5, the deodorant-providing surfaces of the toilet paper base sheets 71A and 71B may be attached to each other and laminated and integrated.

  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. Furthermore, in this embodiment, embossing and deodorizing agent are applied to each of the toilet paper base papers 71A and 71B fed from the original fabric rolls 70A and 70B, but only one embossing device is provided. The embossing and deodorant may be applied only to one toilet paper base.

  The specific embossed pattern, the embossed depth, the embossed density, the shape of each embossed embossing, and the embossed area of the toilet paper 7 according to the present embodiment are not limited. It can be determined as appropriate in consideration of design, bulkiness, softness improvement and surface smoothness. Needless to say, the configuration of the embossings 26A and 26B of the toilet paper 7 is determined by the configuration of the embossing projections formed on the peripheral surface of the embossing roll.

However, in the toilet roll and toilet paper manufacturing method of the present embodiment, the embossing 26A and 26B of the toilet paper base sheets 71A and 71B are characteristically formed as shown in FIG. The parts are stacked so that the parts do not face each other. Therefore, it is desirable to configure the embossing rolls 21A and 21B with sufficient consideration for the smoothness of the surface with respect to the embossed shape. Specifically, the embossing depth is not excessively deep and the embossing density should be high or very sparse. As a preferred example, it is desirable that the emboss depth is 3 mm or less and the emboss density is 50 / cm ² or more, or 20 / cm ² or less. When the emboss depth exceeds 3 mm, it becomes easy to feel the roughness due to the embossed convex portion. Further, when the emboss density is 50 pieces / cm ² or more, the embossed convex portions are close to each other, and it is difficult to feel the roughness as a whole. In addition, when the density is less than 20 pieces / cm ^{2, the} portions to which the embosses 26A and 26B are not provided become wide and it is difficult to feel the roughness due to the embossed convex portions.

  Moreover, about the shape of embossing 26A, 26B, it is shown in FIG. 4 corresponding to this as the thing of the shape which chamfered the edge of the top part of the embossing convex part of embossing roll 21A, 21B, and was smoothed. It is desirable that the embossed protrusions 26t, 26t have embosses with smooth edges at the top edges. If the edges are smooth as described above, even if the embossed convex portions 26t and 26t are convex on the outer surface, the touch can be made smooth.

  As the embossing devices 20A and 20B according to the present embodiment, it is desirable that the embossing rolls 21A and 21B are metallic, and the receiving rolls 22A and 22B are elastic whose surfaces are made of rubber or the like. It is a so-called steel rubber type. The combination of the metal embossing rolls 21A and 21B and the surface elastic receiving rolls 22A and 22B is preferable because it is difficult to cause problems such as the problem of adjusting the clearance of the roll and the easy adjustment of the embossing appearance in the width direction. It is. Further, by making the receiving rolls 22A and 22B other than metal, the deodorant-applied surface does not come into contact with the deodorant to be rusted.

  In the present embodiment, the linear pressure between the rolls may be adjusted as appropriate according to the emboss pattern, the transfer state of the deodorant, and the applied amount. In addition, when using metal embossing roll 21A, 21B, even if a deodorizer reacts with a metal, in this invention, the embossing roll can respond only by washing | cleaning. Since the embossing rolls 21A and 21B are cleaned appropriately, there is almost no increase in labor during manufacture. Of course, the embossing rolls 21A and 21B may be made of chrome plating or stainless steel having excellent corrosion resistance.

  Moreover, spray application apparatus 25A, 25B which concerns on this embodiment can spray the chemical | medical solution containing a deodorizing agent, The form is not limited. Suitable examples include a nozzle spray device and a rotor dampening spray application device. The types of spray nozzles in the nozzle-type spray applicator include: an empty conical nozzle that sprays in an annular shape, a full conical nozzle that sprays in a circular shape, a full pyramid that sprays in a square shape, a full nozzle, and a fan nozzle The nozzle diameter, the number of nozzles, the nozzle arrangement pattern, the number of nozzle arrangements, the spraying distance, the spraying pressure, the spraying angle, the concentration of the deodorizing liquid, the viscosity and the like can be appropriately selected and used. Moreover, about the method of atomizing in a nozzle type spray apparatus, a 1 fluid system or a 2 fluid system can be selected suitably. The rotor dampening applicator is a device that sends the liquid to be sprayed onto a disk that rotates at high speed and atomizes the liquid by the centrifugal force of the disk, and controls the particle size of the droplets by changing the speed of the disk. The amount of spray liquid (applied amount) is controlled by changing the amount of liquid fed onto the disk. Since the rotor dampening coating apparatus can spray a small amount of spray liquid while suppressing the scattering of mist droplets, it is easy to uniformly apply to the circumferential surface of the embossing roll. Therefore, this rotor dampening type spray device is particularly suitable as the spray coating device 25A, 25B according to the present invention.

  As described above, in the method for manufacturing the toilet roll 10 according to the present invention, since the spray solution is applied to the peripheral surfaces of the embossing rolls 21A and 21B by the spray coating apparatuses 25A and 25B, toilet paper is used. An appropriate amount of deodorant can be effectively applied to the entire surface of the base paper 71A, 71B. That is, in a roll transfer apparatus used for applying a conventional moisturizing agent, it is difficult to manage at a low application amount because the viscosity of the chemical solution is required to some extent at the time of application. And if it is going to apply | coat the amount of deodorizing agents which can be effectively transferred with a roll transfer apparatus to toilet paper base paper, there exists a possibility of reducing the texture of toilet paper. The decrease in the texture of the toilet paper due to the excessive amount of deodorant varies depending on the type of deodorant, but the tendency is remarkable for polyphenols and the like, which will be described later, especially those containing tannin as an active ingredient. In this way, the amount of deodorant applied tends to be applied in a small amount as compared with the humectant, and it is difficult to adjust to a desired viscosity suitable for roll transfer with such a small amount applied. Therefore, in roll transfer, it was difficult to apply uniformly, but according to the present invention, if the spray application devices 25A and 25B are used, the embossing roll can effectively emulsify a chemical solution containing a diluted low-viscosity deodorant. 21A, 21B can be distributed and uniformly applied to the peripheral surfaces of the embossing rolls 21A, 21B when embossing the toilet paper base sheets 71A, 71B between the embossing rolls 21A, 21B and the receiving rolls 22A, 22B. Toilet paper base 71A, 71B is pressed onto the surface and transferred effectively, so an appropriate amount of deodorant and uniform toilet paper base 71A It is possible to impart to the one surface across the plane of the 71B.

  As described above, in the present invention, the spray coating devices 25A and 25B are used, and the chemical liquid containing the deodorant is applied to the peripheral surfaces of the embossing rolls 21A and 21B, and this is transferred to the toilet paper base papers 71A and 71B. A deodorant can be dispersed and applied over the entire paper surface in a suitable amount. And the toilet paper which has the designability and bulkiness by embossing 26A, 26B, and has a deodorizer provision position in the lamination | stacking inner surface can be manufactured efficiently.

  Further, by using the spray coating devices 25A and 25B according to the present invention, it becomes easy to switch between the production of toilet paper with a deodorant and the production of toilet paper without a deodorant. That is, in the roll transfer device, it is necessary to switch between contact and non-contact between the printing plate roll and the application surface. However, in the case of a spray coating device, it is only necessary to switch the spraying stop. Can be easily switched. Furthermore, with regard to cleaning of the apparatus, the spray coating apparatus is simpler than the roll transfer apparatus. Moreover, it is desirable to provide a partition so that the area between the spray port of a spray coating device and the coating position of an embossing roll peripheral surface may be enclosed. The transfer efficiency of the deodorant to the embossing roll is improved, and the scattering of the deodorant to the periphery is prevented. Furthermore, it becomes easy to clean the apparatus and to switch between applying and not applying the deodorant.

  Here, in the present embodiment, the chemical liquid containing the deodorant can include an adhesive, an ink, a solvent, and other auxiliary agents for fixing the deodorant, which is an active ingredient, on the toilet paper base paper 71A, 71B. .

  Examples of the solvent include water, alcohols, ethylene glycol, propylene glycol, butylene glycol, isopropyl alcohol and the like. It is desirable to contain at least one of these, and in particular, water and a lower alcohol composed of at least one of propyl alcohol, ethanol, and methanol are preferably contained.

  As an adhesive agent, it can select in the range which does not prevent the effect of a deodorizer, For example, carboxymethylcellulose, polyvinyl alcohol, starch, etc. can be illustrated. When an adhesive is contained in the chemical solution, toilet paper base papers are bonded together after being laminated and integrated, and ply peeling becomes difficult.

  Deodorants according to the present invention include organic acids, organic acid salts, polyphenols, polyphenol derivatives, polyphenol analogs, amphoteric surfactants, citric acid, graft polymer deodorants, betaine compound deodorants, cedar, Examples include essential oils extracted from cypress and the like. These can be used alone or in combination of two or more.

Toilet paper base paper 71A of the deodorant, the application amount of the 71B is preferably from 0.0001~1.0g / m ^2, more preferably from 0.003~0.4g / m ^2. Most preferably, it is 0.05-0.25 g / m < ² >. If it is less than 0.0001 g / m ² , the deodorizing effect is not sufficient, and if it exceeds 1.0 g / m ² , the texture of the toilet paper base may be lowered, and even if a further deodorant is added. The effect of improving the deodorizing effect is small or the cost is high.

  Particularly suitable among the deodorizers according to the present invention are those containing at least one of polyphenols, polyphenol derivatives and polyphenol analogues (hereinafter also referred to as polyphenols). These have a high deodorizing function with respect to ammonia, which is one of the malodorous components, due to the reactivity with phenolic hydroxyl groups, but they are a kind of organic acid and oxidize iron, so the toilet according to the present invention It is particularly suitable for use in a roll manufacturing method.

  Among the above polyphenols and the like, there are those having a deodorizing function that are reactive to hydrogen sulfide, methyl mercaptan, and trimethylamine in addition to ammonia. Of course, the deodorizer used in the present invention is such a deodorizer. It may be a thing.

Among polyphenols and the like, tannin and its derivatives are desirable. Tannins and tannin derivatives are excellent in deodorizing function because they have a large molecular weight and a large number of phenolic hydroxyl groups, but are particularly desirable as a 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, 0.0001~1.0g / m ^2, preferably 0.003~0.5g / m ^2.

  Here, when polyphenol or the like is used as a deodorant, the polyphenol containing 0.1 to 40% by weight, preferably 0.5 to 20% by weight, particularly preferably 1.0 to 10% by weight of the polyphenol or the like is used. The adhesive, ink, solvent such as water and lower alcohol, and other auxiliaries can be mixed with the system deodorant liquid to obtain a chemical liquid containing the deodorant.

  In addition, the polyphenol-based deodorant liquid may contain an auxiliary agent such as a solvent such as water, a preservative, and a pH adjuster as other components other than the polyphenol. In addition, the polyphenol deodorant according to this embodiment includes other organic acids and organic acids for the purpose of stability, addition of functional groups to polyphenols, and further improvement of the deodorizing effect due to its own reactivity. A salt may be blended. Examples of the organic acid and organic acid salt include lactic acid, tartaric acid, malic acid, fumaric acid, succinic acid, citric acid, glutaric acid, amino acid, adipic acid, ascorbic acid, and inorganic or organic salts thereof. Examples of inorganic bases that form salts include alkali metal or alkaline earth metal hydroxides, oxides, carbonates, bicarbonates such as sodium, potassium, lithium, calcium, and magnesium. Examples of the organic base include nitrogen-containing bases such as compounds having groups such as primary, secondary or tertiary amines, imino groups, guanidino groups, imidazolino groups, imidazolyl groups and pyridyl groups.

  In addition, what is marketed can be used for a polyphenol type deodorizing liquid. For example, Pancil COS-15, Pancil COS-17, Pancil CL-10, Pancil AS-10, Pancil AS-20, Pancil BA-210-1, Pancil COS-5, Pancil FG-22 manufactured by Release Kagaku Kogyo Co., Ltd. Pancil FG-25, Pancil FG-30, Pancil FG-60, Pancil FG-70, Pancil FG-99, Pancil FX10, Pancil PO-10, Pancil BA-200E-1 can be used as appropriate.

  Since the application of the deodorant of the present embodiment as described above is performed in a series of flow of the log manufacturing process in the winder X2, the productivity of the toilet roll is not lowered.

  In addition, the deodorizer application surface of the toilet paper base sheets 71A and 71B is attached to the embossing rolls 21A and 71B after the deodorizer is applied to the toilet paper base sheets 71A and 71B until they are stacked and used as the toilet paper 7. It can be positioned on the inner surface of the toilet paper 7 without contacting with a guide roll other than 21B. Therefore, even if the deodorant has a certain reactivity with a metal such as iron, there is a risk that the metal member other than the embossing roll may be oxidized, corroded, discolored or damaged in the process of applying the deodorant. Absent. Of course, the trouble of cleaning the equipment due to the adhering deodorant is also reduced.

  Furthermore, the toilet paper 7 formed in the present embodiment has a deodorant imparting surface located on the laminated inner surface 7x of the toilet paper 7, as particularly understood from FIG. Even in the transport process until the toilet paper 7 is wound around the long paper tube 30 thereafter, the deodorant application surface can be prevented from coming into contact with a member constituting the winder X2, such as a guide roll. 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. There is little possibility of being damaged. Of course, the trouble of cleaning the equipment due to the adhering deodorant is also reduced. Moreover, if it is the application position of the said deodorant, even when using the toilet paper 7 as the toilet roll 10 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, if the log 75 in which the toilet paper 7 with the deodorant applied to the laminated inner surface 7x is wound around the long paper tube 30 is manufactured, as shown in FIG. A plurality of logs are stocked by the log accumulator X3 and moved to the log cutter facility X4 at the subsequent stage. 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. The log 75 according to the present embodiment does not have a deodorant imparting surface exposed on the surface thereof, and therefore, even if a deodorant that may damage the metal is used as described above, the log 75 is erased in the processes after the log formation. There is no risk that odorants will damage manufacturing 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 obtained by winding a long toilet paper 12 around a paper tube 11, and a deodorant is applied to the toilet paper 12.

  As for the size and the like of the toilet roll 10 of this embodiment, the width L1 is 100 to 115 mm, the diameter L2 is 100 to 120 mm, the winding length (full length of the toilet paper) is 18 to 70 m, and the paper tube inner diameter L3 is 35 to 35 mm. 50 mm is desirable. If it is this size, the paper holder for a general toilet roll can be utilized, the length of the toilet paper 12 is also sufficient, and there is no possibility that winding may collapse.

  On the other hand, the toilet paper 12 constituting the toilet roll of the present embodiment has a ply structure in which a plurality of toilet paper base papers 13 are laminated, and is provided with an emboss 14. Then, in particular, the toilet paper base paper 13 constituting the ply is provided with the emboss 14 so that the embossed convex portion 14t is laminated on the outer surface side and laminated on the inner surface of the emboss 14. A void 15 is formed between the base paper and other toilet paper base paper, and at least an embossed convex portion is formed on the laminated inner surface 13x of the toilet paper base paper 13 so that a deodorant is applied. (In FIG. 7, the deodorant application position is indicated by reference numeral 16).

The specific configuration of the emboss 14 is not limited. However, since the embossed convex portion 14t is convex on the outer surface, it is necessary to sufficiently consider the smoothness of the surface. The embossing density should be high or very sparse. As a preferable example, it is desirable that the emboss depth is 3 mm or less and the emboss density is 50 or more / cm ² or higher, or 20 / cm ² or less. When the depth of the emboss 14 exceeds 3 mm, it becomes easy to feel the roughness due to the embossed convex portion 14t. Further, when the emboss density is 50 pieces / cm ² or more, the embossed convex portions are close to each other, and it is difficult to feel the roughness as a whole. Further, when the density is less than 20 pieces / cm ^{2, the} portion to which the emboss 14 is not applied becomes wide, and it is difficult to feel the roughness due to the embossed convex portion 14t.

  As for one shape of the emboss, it is desirable that the top edge of the embossed convex portion 14t be a smooth embossed convex portion 14t as shown in FIG. By smoothing the edges in this way, the touch can be made smooth even if the embossed convex portions 14t are convex on the outer surface.

On the other hand, the content of the deodorant as the whole toilet paper according to this embodiment is preferably 0.0002 to 2.0 g / m ² as an active ingredient. More preferably, it is 0.006-0.8 g / m < ² >. Most preferably, it is 0.01-0.5 g / m < ² >. 0.0002 g / m hardly deodorant effect can be obtained is less than ^2, although it exceeds 2.0 g / m ² deodorizing effect can be obtained, with the coating amount is excessive, especially the cost.

  The type of deodorant is as described in the description of the production method, but again, the deodorant includes organic acids, organic acid salts, polyphenols, polyphenol derivatives, polyphenol analogs, amphoteric surfactants, quenchers. Examples thereof include essential oils extracted from acids, graft polymer deodorants, betaine compound deodorants, cedar, cypress, and the like. These can be used alone or in combination of two or more. Among these, those containing at least one of organic acids and organic acid salts are desirable, and in particular, the organic acids are desirably polyphenols or polyphenol derivatives or analogs.

  Polyphenol, polyphenol derivatives, and analogs exhibit a deodorizing effect by a chemical reaction with a malodorous component in the toilet space, and exhibit an extremely excellent deodorizing effect in the toilet space. Such polyphenols may be such.

  More preferred specific examples of the polyphenols and polyphenol derivatives and analogs according to the present invention are tannin, catechin, rutin, anthocyanin, ellagic acid, coumarin, flavone, and derivatives or precursors thereof. These exert a particularly high deodorizing effect on the odor component of the toilet. Note that a plurality of these substances may be appropriately provided in the paper tube.

Of the above specific examples, tannin and its derivatives are particularly preferable. Tannin and tannin derivatives are excellent in deodorizing function because they have a large molecular weight and many phenolic hydroxyl groups. Tannin may be either condensed tannin or hydrolyzed tannin. Further, among tannins, cocoon tannins derived from cocoons have a very large molecular weight and are extremely excellent in deodorizing effects. Therefore, the deodorant component according to the present invention contains at least one of cocoon tannins and cocoon tannin derivatives. It is better to do so. However, as the tannins and tannin derivatives increase in concentration, the characteristic brownish brown color becomes prominent, so if applied over 2.0 g / m ² , the toilet paper base will be dyed brownish, reducing the cleanliness. There is a risk of causing.

Here, for the toilet paper 12 of the present embodiment, it is desirable that the paper thickness is 100 to 350 μm, and the rice basis weight per ply is 11.0 to 25.0 g / m ^2. Can ensure the softness and water absorption. Moreover, since the deodorizing agent is given to the laminated inner surface of the toilet paper 12 of the present embodiment, the deodorizing effect is caused by volatilization of the deodorizing agent through the toilet paper base paper 13 or contact between the surrounding air and the deodorizing agent. However, if it is such a rice tsubo and paper thickness, sufficient contact between the deodorant and the surrounding air can be secured. Here, the term “tsubo” refers to the method for measuring the basis weight of JIS P 8124 (1998), and the paper thickness refers to the same conditions after the humidity is sufficiently adjusted under the conditions of JIS P 8111 (1998). The average value measured 5 times using the dial thickness gauge (thickness measuring device) "PEACOCK G type" (made by Ozaki Seisakusho) below. The paper thickness is measured with a plurality of plies.

  Further, the number of plies in the toilet paper 12 is not limited, but is preferably 2 to 4 plies. If it exceeds 4 plies, the toilet paper is too thick and difficult to use, and it becomes difficult to secure a sufficient winding length.

  Furthermore, the constituent material of the toilet paper 12 contains 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 of the present embodiment described above, since the deodorant is applied to the toilet paper 12, the deodorizer is positioned on the peripheral surface 12A occupying a wide range of the exposed portion of the toilet roll 10. For this reason, the deodorizing effect is excellent because the chance of contact with the malodorous component 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 11. FIG.

  In addition, every time the toilet paper 12 is used, the new toilet paper 12 is exposed on the peripheral surface 12A of the toilet roll, so that a new deodorant is also positioned on the peripheral surface every time. Excellent deodorant durability.

  Furthermore, in the toilet roll 10 of this embodiment, since the deodorizing agent is given to the laminated inner surface of the toilet paper 12, the deodorizing agent is volatilized through the toilet paper base paper 13 or the ambient air and the deodorizing agent. Deodorizing effect is exhibited by contact, but since the toilet paper 12 has a gap between each ply by the embossing 14, it is excellent in air permeability, and the deodorant and the outside air are easily in contact with each other. High deodorizing effect. In addition, since the deodorant is applied to the inner surface of the toilet paper 12, it is difficult to touch the user's skin during use.

  Furthermore, since the toilet roll 10 of this embodiment can be manufactured by 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.
