  However, when printing is performed by applying ink to paper, the ink usually solidifies as the ink dries, causing a problem that the printed surface on which the ink is applied becomes unpleasant.

  In this regard, the technique disclosed in Patent Document 1 is to apply a mixture of printing ink and lotion solution onto thin paper, but when the printing ink contained in this mixture is solidified, the entire paper feels poor. Has the problem of becoming. Furthermore, since the technique of patent document 1 mixes printing ink and a lotion chemical | medical solution and it applies to a thin paper, when a printing ink adheres to a thin paper, an ink oozes and the external appearance of a printing part worsens. There is a problem.

  Moreover, although the technique disclosed in Patent Document 2 is to apply a moisturizing agent to the non-printing surface of tissue paper, there is a risk of giving an unpleasant touch when the printing surface of tissue paper comes into contact with the user's skin. There is.

  Therefore, at present, there is a need for an apparatus and a method for producing a moisturizing paper that prevents the moisturizing paper from being deteriorated due to the effect of solidification of the printing ink applied to the moisturizing paper and that causes less bleeding of the printing ink. ing.

Therefore, the inventors of the present invention, as a result of intensive investigations on means for solving the problems of the above-mentioned conventional invention, after printing on the moisturizing paper, by applying a moisturizing agent to the printing surface of the moisturizing paper, It has been found that even when the printing ink is solidified, the touch of the entire moisturizing paper can be prevented from worsening, and the bleeding of the printing ink can be reduced. The inventor has conceived that the problems of the prior art can be solved based on the above knowledge, and has completed the present invention.
Specifically, the present invention has the following configuration.

The 1st side surface of this invention is related with the manufacturing apparatus for manufacturing moisture retention paper.
The manufacturing apparatus of the present invention includes a printing unit 21 and a humectant application unit 22.
The printing unit 21 is a means for printing on the base paper of the moisturizing paper.
The humectant application unit is means for applying the humectant to the printing surface of the base paper that has been printed by the printing unit 21.
Thereby, this invention can manufacture the moisture retention paper to which printing was given.
The base paper of the moisturizing paper may be composed of a single sheet of paper, or may be formed by stacking two or more sheets of paper.

  By applying a moisturizing agent to the printed surface after printing on the base paper as in the above configuration, the conventional problem that the moisturizing paper feels worse as the ink solidifies can be solved. . In the present invention, the ink and the humectant are not applied simultaneously or mixed to the base paper, but the humectant is applied after the ink is applied. Therefore, the ink is dissolved into the humectant and the ink bleeds. It is possible to eliminate the problem of occurrence of

  The production apparatus of the present invention preferably further includes a first tension applying unit 23 that applies tension to the base paper that has been printed by the printing unit 21.

  In general, when printing is performed by applying ink to paper, the ink applied to the paper solidifies, causing wrinkles in the printed portion of the paper, resulting in poor appearance. Also, when forming a set of moisturizing paper by stacking multiple sheets of paper, if wrinkles occur on the printed paper, there is a risk that voids will occur between the multiple papers. . When voids are generated between a plurality of papers, there is a problem that when the moisturizing agent is applied, the moisturizing agent does not effectively penetrate into all of the plurality of papers, resulting in uneven impregnation of the moisturizing agent. In this regard, as in the above configuration, by applying tension to the base paper on which printing has been performed by the printing unit 21 and extending the printing ridge, the appearance of the moisture retaining paper can be improved. Moreover, even if the moisture retaining paper is formed by overlapping a plurality of papers, the moisture retaining agent can be effectively penetrated into all the papers.

  The manufacturing apparatus of the present invention preferably further includes a second tension applying unit 24 that applies tension to the base paper on which the moisturizing agent is applied by the moisturizing agent applying unit 22.

  Even if the base paper is formed by laminating a plurality of papers, for example, by applying a tension to the base paper after applying the moisturizer by the moisturizer application unit 22 as in the above configuration, The moisturizing agent can penetrate evenly throughout the base paper.

  The production apparatus of the present invention preferably further includes a drying unit 25 that dries the base paper that has been printed by the printing unit 21. The drying unit 25 may naturally dry the base paper, or may dry the base paper using an air drying device such as a dryer.

  Normally, if the ink applied to the base paper is not completely dried and a moisturizing agent is applied to the printing surface, the ink may be dissolved in the moisturizing agent and spread. In this respect, as described above, the base paper on which printing has been performed by the printing unit 21 is once dried and then applied with a moisturizing agent, so that ink bleeding can be more effectively eliminated. In addition, by keeping the entire base paper in a dry state in the drying unit 25, the moisturizing agent applied to the base paper can easily penetrate the entire base paper. Therefore, the moisturizing paper can be finished beautifully and beautifully, and the moisturizing agent can be efficiently permeated throughout the base paper.

  The manufacturing apparatus of the present invention preferably further includes a folding unit 26 and a carton stuffing unit 27. The folding unit 26 is a means for cutting the base paper coated with the moisturizing agent into a predetermined width, and then folding the base paper into a predetermined length. Further, the carton stuffing unit 27 is means for stuffing the moisturizing paper 10 that is folded and cut to a predetermined length into the carton.

  When moisturizing paper is used as sanitary paper packed in a carton such as tissue paper, in the manufacturing process, after a plurality of papers are stacked, they are taken up by a take-up roll and conveyed to another device. It is common. On the other hand, as shown in the above configuration, after a plurality of papers are overlapped, the folding process is performed on the downstream side, and the process of filling the carton is performed with a series of manufacturing apparatuses, so that the manufacturing process can be omitted. As a result, the manufacturing cost can be reduced.

The 2nd side surface of this invention is related with the manufacturing method for manufacturing moisturizing paper.
The production method of the present invention includes a printing process and a moisturizing agent application process.
The printing process is a process of printing on the base paper of the moisturizing paper.
The moisturizing agent application step is a step of applying a moisturizing agent to the printing surface of the base paper that has been printed in the printing step.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments described below, but includes those appropriately modified by those skilled in the art from the following embodiments.
In the present specification, “A to B” means “A or more and B or less”.

(1) 1st Embodiment FIG. 1: is a schematic side view which shows the whole structure of the manufacturing apparatus 20 regarding the 1st Embodiment of this invention. The manufacturing apparatus 20 according to the first embodiment is an apparatus for forming a moisturizing paper by overlapping a plurality of papers. For example, the moisturizing paper is preferably formed by overlapping the first paper 1 and the second paper 2, and may be formed by overlapping the third paper 3.

  As shown in FIG. 1, in the manufacturing apparatus 20, a first unwinding roller 31 and a second unwinding roller 32 are arranged on the upstream side. The first paper 1 is sent out from the first unwinding roller 31, and the second paper 2 is sent out from the second unwinding roller 32. The first paper 1 and the second paper 2 are superposed on each other in the superposition unit 35 to become a base paper of the moisturizing paper. A printing unit 21 is disposed on the downstream side of the overlapping unit 35, and the printing unit 21 performs printing on the base paper. A drying unit 25 is disposed on the downstream side of the printing unit 21, and the drying unit 25 dries the base paper on which printing has been performed. A first tension applying unit 23 is disposed on the downstream side of the drying unit 25. The tension applying unit 23 applies tension to the base paper and extends the printing paper. A moisturizing agent applying unit 22 is disposed downstream of the first tension applying unit 23, and the moisturizing agent applying unit 22 applies the moisturizing agent to the printed surface of the base paper. . Further, a second tension applying unit 24 is disposed on the downstream side of the moisturizer application unit 22, and the second tension applying unit 24 allows the moisturizer applied to the base paper to uniformly penetrate the base paper. Apply tension to the wire. The base paper that has passed through the second tension applying unit 24 is taken up by the take-up roller 36. Thereafter, the base paper taken up by the take-up roller 36 is set in another well-known processing device in a roll shape, and is formed as moisture-retaining paper.

  As shown in FIG. 1, the base paper on which the first paper 1 and the second paper 2 are overlapped is conveyed further downstream via a pinch roller 34 positioned downstream of the overlapping portion 35. The base paper is finally taken up by the take-up roller 36 as described above. For this reason, the base paper is connected from the first unwinding roller 31 and the second unwinding roller 32 to the winding roller 36. The base paper is given a constant tension in the transport direction (longitudinal direction of the paper) by the pinch roller 34, the auxiliary roller 37, the take-up roller 36, etc. existing at appropriate positions in the manufacturing apparatus 20, and is transported without slack.

(1-1. Unwinding roller, base paper)
As shown in FIG. 1, a first unwinding roller 31 and a second unwinding roller 32 are located on the upstream side of the manufacturing apparatus 20. The first unwinding roller 31 holds the first paper 1, and the second unwinding roller 32 holds the second paper 2. The first paper 1 and the second paper 2 are superposed in the superposition unit 35 to become a base paper of the moisturizing paper.

  In the present invention, the types of the first paper 1 and the second paper 2 that are used as the base paper for the moisturizing paper are not particularly limited. For example, a wide variety of known papers that are used as the base paper for sanitary paper can be used. Can be adopted. Examples of sanitary paper are tissue paper, dust paper, paper towels, kitchen towels, kitchen sheets, cooking sheets, or toilet paper.

Since a humectant is applied to the base paper used in the manufacturing apparatus 20 of the present invention, it is preferable to employ a paper having a strength that does not easily break even when the humectant is applied. As a raw material of the base paper, for example, a mixture of softwood bleached kraft pulp (NBKP) and hardwood bleached kraft pulp (LBKP) can be used. The base paper preferably contains, for example, 30% to 90% NBKP and 10% to 70% LBKP. The basis weight per sheet paper, for ^example, and ^{11g / m 2 ~19g / m 2} , to be 13g / ^{m 2} ~18g / m 2 is ^{preferably, 15g / m 2 ~17g / m} 2 It is particularly preferred.

  In addition, since the base paper used in the manufacturing apparatus 20 of the present invention is printed, it is preferable to employ a paper having a fine crepe and a smooth paper surface. Further, it is preferable that the contact surface of the base paper with the Yankee dryer is the printing surface. As a result, the printing becomes clear and the touch is improved.

In the manufacturing apparatus 20 of the present invention, the type of paper used as the first paper 1 and the type of paper used as the second paper 2 may be different. For example, since the first paper 1 which printing is performed, in order to sharpen the printing ink, the basis weight is preferably, for example, ^{10g / m 2 ~14g / m 2} . On the other hand, the second paper 2 which printing is not performed, as can include humectant rich, the basis weight is preferably, for example, ^{15g / m 2 ~19g / m 2} .

(1-2. Printing section)
The printing unit 21 is located on the downstream side of the overlapping unit 35. The printing unit 21 has a function of printing on the base paper. In particular, in the embodiment shown in FIG. 3, the printing unit 21 performs printing on the first paper 1. Of the surfaces of the base paper, the surface on which printing is performed becomes the printing surface 1a. As the printing unit 21, for example, a known rotary printing application device can be adopted. For example, the printing unit 21 includes a cylindrical printing drum 211 and a plurality of printers 212 arranged on the circumference of the printing drum 211. Then, the printing unit 21 sequentially applies printing ink to the conveyed base paper by the plurality of printers 212 while winding the base paper around the printing drum 211.

  The design and color of printing performed by the printing unit 21 can be appropriately changed according to the user's preference. For example, ink tanks that supply printing ink to a plurality of printers 212 can be printed in various colors by filling them with different colors of printing ink. Thus, various characters, patterns such as floral patterns, animal patterns, and plant patterns, characters, symbols, and figures can be freely set according to the user's preference.

  Various known inks can be used regardless of whether they are oily or water-based. The ink used for printing is, for example, a water-soluble ink containing a pigment, an aqueous varnish (synthetic resin and water), and an additive, and preferably containing ethanol as a solvent. The ink preferably contains an epoxy-modified polyamide resin as a binder resin. Epoxy-modified polyamide resin is obtained by reacting a polyamine component containing polyalkylene polyamine as an essential component and a dicarboxylic acid component under the condition that amino groups are present in excess, and further reacting with an epihalohydrin. The resulting epoxy-modified polyamide resin. If paper printing is performed using such a water-soluble ink, printing can be performed without impairing the soft texture and suppressing ink back-through and paper shrinkage.

(1-3. Drying part)
A drying unit 25 is located on the downstream side of the printing unit 21. The drying unit 25 has a function of drying the printing ink applied to the base paper. In the example shown in FIG. 1, the drying unit 25 naturally dries the base paper. The drying unit 25 has a structure capable of drying the printed ink by spreading the base paper long with a roller and transporting the base paper so that the printing surface 1a of the base paper is in contact with air.

  The drying unit 25 is located between the printing unit 21 and the first tension applying unit 23, and the drying time from the printing unit 21 to the first tension applying unit 23 is, for example, 4 seconds to 30 seconds. , 5 seconds to 20 seconds, or 6 seconds to 10 seconds. The printing ink applied to the printing surface 1a of the base paper can be surely dried in about 4 seconds.

  In addition, as the drying unit 25, a dryer that blows hot air, cold air, or room temperature air to the base paper can be employed. By mechanically sending air to the base paper, the printing ink can be dried quickly and the color of the printing ink can be improved.

(1-4. First tension applying portion)
A first tension applying unit 23 is located downstream of the drying unit 25. The first tension applying unit 23 has a function of applying tension to the base paper for the purpose of extending the wrinkles generated by the solidification of the printing ink. As the first tension applying unit 23, for example, a roll-like tension controller that presses the base paper in a direction (orthogonal direction) orthogonal to the conveyance direction can be employed. The tension controller is configured to be driven up and down in a direction orthogonal to the transport direction of the base paper and to rotate in the transport direction of the base paper, and can adjust the tension applied to the base paper. As a result, tension can be applied to the base paper, and wrinkles generated by the solidification of the printing ink are stretched.

  The first tension applying unit 23 applies a tension of 10% to 90%, 20% to 80%, 30% to 70%, or 40% to 60% with respect to the breaking load in the orthogonal direction of the base paper. Is preferred. For example, when the breaking load in the orthogonal direction of the base paper is 60 N per 100 mm width, the tension applied by the first tension applying unit 23 is preferably 6 N to 54 N per 100 mm width. Thereby, only the wrinkles produced by solidification of the printing ink can be stretched without breaking the base paper.

  The first tension applying unit 23 presses the base paper from either the first paper 1 side on which printing has been performed or the second paper side on which printing has not been performed. Also good. However, when the first tension applying unit 23 is arranged to press the second paper 2 side, the printing ink applied to the first paper is smeared or smudged when the tension is applied. Can be prevented.

  Further, the first tension applying unit 23 may apply tension to the base paper by being sandwiched by pressing rollers (not shown) from both sides of the base paper. Even with such a structure, it is possible to extend the printing wrinkles generated on the base paper as in the above structure.

(1-5. Moisturizer application part)
A moisturizing agent application unit 22 is located downstream of the first tension applying unit 23. The humectant application unit 22 includes, for example, a humectant tank and an application unit, and has a function of applying the humectant to the printing surface 1a of the base paper. For example, a nozzle sprayer or a rotor sprayer can be used as the humectant application unit 22. The nozzle type sprayer is a type of sprayer that applies pressure to the moisturizing agent in the nozzle and sprays the mist moisturizing agent from the tapered opening. In addition, the rotor type sprayer is a type of sprayer in which a plurality of fins are attached to the rotor, and the rotor is rotated at a high speed and the humectant adhering to the fins is sprayed in a mist form by the centrifugal force. However, the device used as the moisturizing agent application unit 22 is not limited to these, and any device capable of applying the moisturizing agent to the printing surface 1a of the base paper may be used. For example, the base paper using a transfer roller However, a device for applying a moisturizing agent and other known devices can also be used. It is preferable that the humectant is applied to the entire printing surface 1a of the base paper by these devices.

  As the moisturizing agent applied by the moisturizing agent applying unit 22, various liquids used in general moisturizing paper can be used. Examples of humectants include polyhydric alcohols such as glycerin, diglycerin, propylene glycol, 1.3-butylene glycol, and polyethylene glycol; sugars such as sorbitol, glucose, xylitol, maltose, maltitol, mannitol, and trehalose; It is possible to use a liquid (may be a solution) containing one or two or more components in a system drug and derivatives thereof; higher alcohols such as cetanol, stearyl alcohol, and oleyl alcohol; liquid paraffin and the like. In addition to the moisturizer, the moisturizer application unit 22 may apply a disinfectant, a chemical solution containing a medicinal component, a liquid containing a fragrance or a colorant to the paper.

  The amount of the liquid (including the moisturizing agent and other liquids) applied by the moisturizing agent application unit 22 is the amount of the liquid adhering to the moisturizing paper out of the total mass of the moisturizing paper as the final product, for example, 2 to 2. It is preferably 30% by mass, 3 to 25% by mass, or 4 to 20% by mass. By making the amount of liquid 2% by weight or more, moisturizing paper can be surely moistened. In addition, by setting the amount of liquid to 30% by weight or less, it is possible to effectively prevent the problem that the amount of liquid is too large, the paper strength becomes weak, and the paper breaks.

(1-6. Second tension applying portion)
A second tension applying unit 24 is disposed on the downstream side of the humectant application unit 22. The second tension applying unit 24 applies a predetermined tension to the base paper for the purpose of allowing the moisturizing agent applied to the printing surface 1a of the base paper to uniformly penetrate the entire base paper. The second tension applying unit 24 can employ the same configuration as the first tension applying unit 23 described above. That is, as the second tension applying unit 24, it is preferable to employ a roll-like tension controller that presses the base paper in a direction (orthogonal direction) orthogonal to the transport direction. The tension controller is configured to be driven up and down in a direction orthogonal to the transport direction of the base paper and to rotate in the transport direction of the base paper, and can adjust the tension applied to the base paper. In this way, by applying tension to the whole base paper, it is possible to promote the penetration of the moisturizing agent applied to the printing surface 1a of the base paper into the whole base paper.

(1-7. Winding roller)
A take-up roller 36 is located downstream of the second tension applying unit 24. The take-up roller 36 takes up the base paper coated with the moisturizing agent and holds it in a roll shape. By holding the base paper in a roll shape for a certain period of time by the take-up roller 36, the penetration of the humectant is further uniformized. The base paper taken up by the take-up roller 36 is set in another processing apparatus in a roll shape. As the processing apparatus, a known sheet roll processing apparatus that processes toilet paper, a tissue paper processing apparatus that processes tissue paper, or the like is employed. For example, a tissue paper processing apparatus is provided with a folding section and a carton stuffing section. The fold processing section folds and cuts the base paper to form a paper group of a size and number of sheets suitable for carton stuffing. By the stuffing unit, the paper group formed by the folding unit is stuffed into a carton. The carton stuffing unit opens a carton manufactured on a separate line and pushes the paper group into its internal space. Then, for example, the paper group is enclosed in the internal space by pasting the inner flap and the outer flap together. As a result, the moisturizing paper can be packed in the carton. As the folding processing unit, for example, a known folding plate type processing machine or a rotary cylinder type processing machine can be adopted, and a known device can be adopted as the carton filling unit. Thus, a moisturizing paper product in which a moisturizing agent is applied to sanitary paper such as tissue paper or toilet roll is manufactured.

  The base paper taken up by the take-up roller 36 is preferably put on a pallet and then sealed with a plastic film such as polyethylene, polypropylene, or polyester. The base paper is sealed with a plastic film, and the moisturizing agent can be adapted to the whole base paper by allowing about 24 hours.

(1-8. Third unwinding roller)
The manufacturing apparatus 20 according to the first embodiment can also manufacture a moisturizing paper obtained by further superimposing the third paper 3 in addition to the first paper 1 and the second paper 2. That is, the manufacturing apparatus 20 of the first embodiment may include a third unwinding roller 33 for unwinding the third paper 3. For example, as shown in FIG. 1, the second paper 2 may be superposed on the third paper 3 and then the first paper 1 may be superposed on the second paper 2 as a base paper. Good. Thereby, it is possible to manufacture a moisturizing paper having three layers of paper. When the paper overlaps with three layers, the strength of the moisturizing paper containing the moisturizing agent can be improved.

(2) Second Embodiment Next, a manufacturing apparatus 20 according to a second embodiment of the present invention will be described with reference to FIG. Regarding the second embodiment of the present invention, the description of the points having the same configuration as the first embodiment described above will be omitted. That is, the second embodiment has the same configuration as the first embodiment up to the point that printing is performed on the base paper of the moisturizing paper and the moisturizing agent is applied. However, the second embodiment does not have a take-up roller for winding the base paper coated with the moisturizing agent, but has a folding unit 26 and a carton stuffing unit 27 instead. In the second embodiment, the moisturizing paper is formed, the moisturizing paper is folded, and the moisturizing paper is packed in a carton in a series of manufacturing apparatuses. Therefore, the manufacturing apparatus 20 according to the second embodiment can be suitably used as a sanitary paper manufacturing apparatus that is sold in a carton such as tissue paper.

(2-1) Folding section The folding section 26 is arranged downstream of the second tension applying section 24, cuts and folds the base paper into which the moisturizing agent has permeated, and is suitable for packing and carton. It has the function of forming paper groups. For example, a known folding plate type processing machine or a rotary cylinder type processing machine can be adopted as the folding processing unit 26.

  Moreover, since the manufacturing apparatus of this invention is for manufacturing the moisture retention paper in which the several paper was laminated | stacked, it is preferable to join a several paper mutually by embossing in the case of a folding process. This makes it difficult for a plurality of papers to be separated during use.

  For example, the folding processing unit 26 cuts the base paper that has passed through the second tension applying unit 24 into a predetermined width along the flow direction. Thereafter, the folding unit 26 stacks a plurality of base papers having a predetermined width while appropriately folding them in a Z shape by a folding machine. And the folding process part 26 is folded and laminated | stacked, and cut | disconnects a base paper to predetermined length along the direction orthogonal to the flow direction. Thereby, a moisturizing paper group having a predetermined width and a predetermined length suitable for carton filling is formed.

  In addition, in an apparatus for manufacturing a moisture retaining paper impregnated with liquid and having low strength, such as the manufacturing apparatus of the present invention, it is preferable to use a rotary cylinder type processing machine as the folding processing section 26. A rotary cylinder type processing machine is a processing machine that consists of two cylinders equipped with a vise (holding) and a tucker (pushing), and alternately feeds two long papers while rotating the cylinder. The paper can be folded by repeating the cutting operation after folding. For this reason, folding can be achieved without imposing excessive load on the moisture retaining paper.

(2-2) Carton Stuffing Unit The carton stuffing unit 27 is located on the downstream side of the folding processing unit 26 and performs a work of packing the moisturizing paper group formed by the folding processing unit 26 into the carton. The carton stuffing unit 27 opens a carton manufactured in a separate line and pushes the paper group into the internal space. Then, for example, the paper group is enclosed in the internal space by pasting the inner flap and the outer flap together. As a result, the moisturizing paper can be packed in the carton. A known device can be adopted as the carton stuffing unit 27.

(3) Manufacturing method of moisturizing paper Next, the manufacturing method of moisturizing paper is demonstrated. The method for producing the moisturizing paper according to the present invention is basically performed using the above-described moisturizing paper producing apparatus 20. The method of manufacturing the moisture retaining paper includes a printing process, a drying process, a first tension applying process, a moisturizing agent applying process, and a second tension adding process. First, in the printing process, printing is performed on the base paper of the moisturizing paper to form the printing surface 1a. Next, in the drying step, the printed base paper is dried. Further, in the first tension applying step, tension is applied to the dried base paper, and the printing paper is stretched. Subsequently, in the moisturizing agent application step, the moisturizing agent is applied to the printing surface 1a of the base paper with the wrinkles extended. At this time, in the moisturizing agent application step, it is preferable that the moisturizing agent is applied to the entire printing surface 1a of the base paper. Further, in the second tension applying step, tension is applied to the base paper so that the moisturizing agent applied to the base paper is totally penetrated. Then, the base paper is taken up by a take-up roller. Thereafter, the base paper may be folded by the folding processing unit and packed in the carton by the carton filling unit.

FIG. 3 shows an example of the moisturizing paper 10 in which two papers are laminated.
FIG. 3A shows an example of a state in which two papers are laminated. FIG. 3B shows a state where two sheets of paper are separated.
As shown in FIG. 3, according to the present invention, printing is performed on one side of the first paper 1, and the one side becomes the printing surface 1a. Further, a moisturizing agent is applied from the printing surface 1 a side of the first paper 1. On the other hand, the second paper 2 is superimposed on the non-printing surface 1b side of the first paper. The moisturizing agent applied to the first paper 1 penetrates from the first paper 1 to the second paper, and as a result, the entire moisturizing paper 10 becomes wet. Moreover, since the moisturizing agent is applied to the printing surface 1a side of the first paper 1, the touch of the moisturizing paper 10 does not deteriorate due to the solidification of the printing ink, and the good touch is maintained.

FIG. 4 shows an example of the moisturizing paper 10 in which three papers are laminated.
As shown in FIG. 4A, according to the present invention, the moisture retaining paper 10 in which the third paper 3 is laminated in addition to the first paper 1 and the second paper 2 can be obtained. As shown in FIG. 2B, the moisture retaining paper 10 has the printing surface 1 a of the first paper 1 positioned on the outer surface of the moisture retaining paper 10. On the other hand, the second paper 2 is superimposed on the non-printing surface 1 b of the first paper 1. In addition, when the surface of the second paper 2 that contacts the first paper 1 is a contact surface 2a and the surface that does not contact the first paper 1 is a non-contact surface 2b, the non-contact of the second paper 2 is determined. The third paper 3 is overlaid on the contact surface 2b. As described above, when the moisture retaining paper 10 is formed, by stacking three sheets of paper, it is possible to obtain a moisture retaining paper that has high strength and is not easily torn even when printing or applying a moisture retaining agent.

  As mentioned above, in this specification, in order to express the content of this invention, embodiment of invention was described, referring drawings. However, the present invention is not limited to the above-described embodiments, but includes modifications and improvements obvious to those skilled in the art based on the matters described in the present specification.
