Description

TECHNICAL FIELD [0001] The present invention relates to a sanitary papermaking sheet,

The present invention relates to a sanitary papermill and a method of manufacturing the same.

It is well known that sanitary napkins, also called lotion types, contain a chemical such as a moisturizing or softening agent.

This kind of sanitary papilloma is also called a lotion tissue or a lotion toilette, and is distinguished from a wet tissue of a wet type, and is in a non-humid state and used in the same way as a general non-moisturizing tissue paper or toilet paper.

On the other hand, in hygienic papers such as toilet paper, tissue paper, etc., characters, figures, and designs are printed with ink or the like to give a shape.

The hygienic thin paper having such a printed shape is excellent in designability and has a high customer suction force and is also used in the lotion tissue and the like.

Conventionally, in producing a sanitary papermill paper having a shape that has been treated with such a paper treating agent, the papermaking paper treating agent is first applied to a base paper, and then the pattern is printed.

Therefore, a shape is printed by printing a figure or the like again on the surface of the paper on which the medicine is applied.

[Patent Document 2] Japanese Patent Application Laid-Open No. 2007-135852

However, as described above, since the ink is applied on the coated surface after the application of the medicine as described above, there is a case where the printed portion is blurred and the clear appearance is not obtained.

Particularly, since the shape of the hygienic papermill paper is required to have a low basis weight and softness, the ink is generally printed thinly. For this reason, there has been a problem that stains and scratches are likely to occur.

Therefore, a main object of the present invention is to provide a hygienic foil paper having a clear shape and excellent in functionality such as flexibility.

The present invention, which solves the above problems, and its effect are as follows.

<Invention of claim 1>

Wherein at least one surface of the sanitary napkin has an ink imparting area to which ink is not applied and a chemical applying area to which the chemical liquid is not applied.

(Action effect)

Since the ink application area is not provided with the chemical solution, the chemical solution does not affect the ink adhesion property. In addition, since the ink is not provided in the chemical solution applying region, the effect of the chemical solution is not masked by the ink.

<Invention of Claim 2>

The sanitary napkin according to claim 1, wherein the ink imparting area is all or a part of a shape imparted with ink to draw characters, figures and / or drawings.

(Action effect)

The ink attaching area is a part of the shape of a character, a figure, or a figure, so that the designability is improved.

<Invention of claim 3>

The sanitary napkin according to Claim 1 or 2, wherein 70% or more of the ink-unapplied region is the chemical solution application region.

(Action effect)

The effect of the chemical solution application becomes clear.

<Invention of claim 4>

The sanitary napkin according to any one of claims 1 to 3, wherein the paper thickness of the chemical solution application area is thinner than the ink application area.

(Action effect)

The sanitary papermill of the present invention has excellent performance in wiping off because there is a difference in height on the surface. In addition, when the ink-imparted area forms a figure or the like, it is recognized as a three-dimensional figure, resulting in a higher designability.

<Invention of claim 5>

The sanitary napkin according to any one of claims 1 to 4, wherein the difference between the paper thickness of the chemical solution application area and the paper thickness of the ink application area is 10 to 60 mu m.

(Action effect)

If the difference in thickness of the paper is 10 to 60 占 퐉, the performance of wiping with irregularities is improved, and the area where the ink is adhered is clear and the designability is excellent. Particularly, the difference in the thickness of the paper becomes remarkable in the case of a thin paper sheet having a paper thickness of 100 to 200 mu m.

<Invention of Claim 6>

The sanitary papillary according to any one of claims 1 to 5, wherein the sanitary papillary has a ply structure of one or more ply, has a pore size of 10 to 30 g / m 2 per ply, and has a crepe number of 10 to 50 pcs / Hygienic foil paper as described in Section 1.

(Action effect)

By using the thin paper having the above-mentioned numerical range, the effect of the present invention can be manifested more reliably.

<Invention of Claim 7>

An ink applying step of transferring ink to a portion corresponding to the convex portion of the continuous hygienic thin paper drawn out from the original roll by a chuck roll having a predetermined portion as a convex portion;

After the ink applying step, a chuck roll having concave portions corresponding to the convex portions with respect to the continuous hygienic foil paper is used to transfer the chemical solution so that at least the area to which only the ink is applied and the area to which only the chemical liquid is applied are transferred And a chemical liquid applying step for applying the chemical liquid to the substrate.

(Action effect)

According to the present invention, a region to which only the ink is applied and a region to which only the chemical solution is applied are formed. Therefore, the ink does not spread or the chemical solution application portion is not masked with the ink.

Further, in the ink and the chemical liquid, the sagging effect of the thin paper when imparted to the thin paper paper is different from each other. That is, since the ink has a high viscosity, it is difficult for the ink to penetrate into the paper layer through the surface of the paper, and the chemical solution is likely to be impregnated into the paper layer as compared with the ink. For this reason, the crepe of the thin paper sheet is increased in the portion where only the chemical solution is applied, and the thickness of the paper is lowered. In the portion where the ink only is given, there is no spreading.

By virtue of this function, in the sanitary foil paper produced by the production method of the present invention, the paper thickness of the area where only the ink is adhered is thick, the paper thickness of the area where the other chemical solution is applied is thinned to become a three-dimensional surface, Performance, and design.

Further, since the convex portion and the concave portion correspond to each other in the present invention, it is possible to obtain an effect that the portion on which the ink is attached becomes clear.

<Invention of Claim 8>

(Action effect)

It becomes hygienic thin paper with excellent design.

INDUSTRIAL APPLICABILITY As described above, according to the present invention, there is provided a hygienic foil paper having a clear print shape and further excellent in functionality such as flexibility.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Specific examples of the sanitary papers of the present invention include tissue paper, toilet paper, and toilet paper rolls.

The sanitary napkin (X1) of the present invention has an ink applying area (1) to which ink is not applied and a chemical applying area (2) to which an ink is not applied and a chemical liquid is applied on at least one side.

It is preferable that the ink applying area 1 in the sanitary napkin X1 is all or a part of the shape portion P to which ink is applied so as to draw characters, figures and / or drawings.

Therefore, as a form of the present invention, first, as shown in Fig. 1, the ink applying area 1 is a character, a figure and / or a figure P (a pattern in the example) drawn by ink, And a form in which the chemical solution application area 2 exists in a range where the chemical solution application area does not overlap.

In this embodiment, as clearly shown in the drawing, there is an area 3 in which neither the chemical liquid nor ink is applied.

However, in the sanitary papermaking paper X1 of the present invention, it is preferable that the effect of the chemical liquid is fully expressed, and the region 3 in which neither the chemical liquid nor the ink is applied is small. More specifically, it is preferable that at least 70% of the area to which ink is not applied is the chemical solution application area.

Therefore, more preferably, as an example of the form shown in Figs. 2 and 3, all the regions of the region to which the ink is not applied are the chemical solution application regions 3.

Among them, the embodiment shown in Fig. 2 is most preferable. This form example is an example in which all the regions of the paper surface are the shape portion P or the chemical solution applying region 2 formed of the ink applying region 1 and they are substantially exclusively present. In other words, all of the shapes P are the ink applying regions 1, and all of the other portions are the chemical liquid applying regions 2.

In practice, this means that overlapping of the shape portion P and the chemical solution application region 2, which occurs as a manufacturing error, or an area in which neither chemical solution nor ink is given.

On the other hand, the form example shown in Fig. 3 is a form in which a chemical liquid application area 2 exists in a part of the shape part P, particularly in the edge part of the shape part P. Even in this form, it is the sanitary thin paper sheet (X1) related to the present invention because it is a region to which the chemical solution is not applied at the central portion of the shape portion P, that is, the ink applying region 1 referred to in the present invention. However, the overlapping portion in this example is preferably less than 5% of the shape portion P (the overlapping portion is indicated by 4 in the figure).

Here, it is preferable that the shape portion P of the sanitary napkin X1 of the present invention has an area ratio of 10 to 30% on one side of the paper surface. If the area ratio is less than 10%, it is difficult to feel the improvement in designability due to the shape imparting. If the area ratio is more than 30%, the thin paper is hardened due to the ink.

On the other hand, specific examples of letters, figures and / or drawings are not particularly limited. For example, a logo mark, a number, various characters, a geometric shape, a floral pattern, and the like can be cited.

Here, though not limited, the difference (DELTA L *) between the L * value in the L * a * b * color system of the ink imparting region and the bottom portion is preferably 3.0 or more. The ink-imparted area becomes clear, and especially the improvement of the designability is remarkable because the figure or the like is drawn. The L * value can be measured using, for example, a measuring device &quot; PF-10 &quot; manufactured by NIPPON KOGYO KABUSHIKI KAISHA CO., LTD.

On the other hand, in the sanitary napkin (X1) of the present invention, the folded structure is not limited. It may be one layer or two or more layers in which two or more thin paper sheets are laminated. The number of sheets of overlapping paper is not particularly limited, and may be suitably changed into, for example, two sheets (two sheets), three sheets (three sheets), four sheets (four sheets), or more. Particularly, two pieces are preferable.

On the other hand, in the sanitary napkin (X1) of the present invention, it is preferable that the paper thickness of the chemical solution applying region (2) is thinner than the ink applying region (1). With such a structure, the performance of wiping off due to the difference in height of the surface is improved, and the unique design in which the shape portion is perceived in three dimensions is exhibited.

In addition, the three-dimensional recognition of the three-dimensionally can be understood by considering the paper thickness of the hygienic papermaking paper. However, this does not necessarily mean that the concavity and convexity (height difference) of the surface is clearly recognized, The thickness and the ink-imparting area are clearly clarified, and the uniqueness of the texture has been expressed in three dimensions.

In the meantime, the papermaking paper, which becomes the base material of the sanitary napkin (X1) of the present invention, can be produced by a known papermaking process such as a wire papermaking process, a press part, a dryer part, a size press, Or the like.

In this papermaking process, suitable chemicals such as a dispersing agent, caustic soda, a pH adjuster such as ammonia water, a defoaming agent, a preservative, a fluorescent dye, a releasing agent, a water resistance agent, a flow modifier and a yield improving agent may be added.

There is no particular limitation on the raw pulp to be used for the paper making raw material. Depending on the application of the water-soluble hygienic papermaking paper, a suitable raw pulp can be selected and used. As the raw pulp, for example, wood pulp, non-wood pulp, synthetic pulp, and old paper pulp may be used. More specifically, the pulp may be selected from the group consisting of groundwood pulp (GP), stone ground pulp (SGP), refiner grand pulp (RGP) (MPP), chemical mechanical pulp (CGP), semi-chemical pulp (SCP), and the like, such as PGW, thermomechanical pulp (TMP), chemical thermomechanical pulp (CTMP), and bridge Chemie thermomechanical pulp (BCTMP) Kraft pulp (KP), soda pulp (AP), sulphite pulp (AP), and the like, such as hardwood kraft pulp (LBKP) and softwood kraft pulp (NBKP) Synthetic pulp (DIP), western pulp (WP), and synthetic pulp (PP) using raw materials such as chemical pulp (CP) such as spun pulp (SP) and dissolved pulp (DP), nylon, rayon, polyester, polyvinyl alcohol (TP), cotton, flax, hemp, yellow ginseng, manila hemp, and rice. A kind or a number of kinds from an auxiliary pulp such as rag pulp, straw pulp, esparto pulp, bergas pulp, bamboo pulp, kenaf pulp and the like, It can be selected appropriately.

Particularly, the raw pulp contains 30 to 80% of NBKP. It is more preferable to use only NBKP and LBKP, and in that case, NBKP: LBKP = 30: 70 to 80: 20 is preferable.

On the other hand, the background color is not limited to white but thin pink or blue may be used because the bloom paper can have the effect of making the appearance part P look clear or the effect of making the overall appearance look luxurious. The adjustment of the background color can be accomplished by conventional techniques such as blending the pigmented pasty material by mixing the coloring materials in advance.

The thin paper may have a so-called microemboss having an area per unit emboss of 0.002 to 0.004 cm 2, an emboss density of 30 to 100 / cm 2, and an emboss depth of 0.05 to 2.0 mm. The shape of the unit emboss can be appropriately shaped.

On the other hand, the sanitary napkin (X1) of the present invention preferably has a value of 10 to 30 g / m 2, more preferably 15 to 25 g / m 2, in the method of measuring the pyeong of JIS P 8124. This is because, when it is less than 10 g / m 2, the strength at the time of dry wiping can not be adequately secured. Also, when 30 g / m &lt; 2 &gt; is exceeded, it becomes too hard and the feeling of touch becomes worse.

Here, the basis weight of the sanitary napkin (X1) means the basis weight of the number of layers when having a double structure. In addition, in the case of such a folded structure, it is not necessary to uniformize the basis weight of each sanitary napkin.

Furthermore, the sanitary napkin (X1) of the present invention preferably has a paper thickness of 100 to 250 mu m. The paper thickness referred to here is the thickness of the paper as a double layer in the case of a double layer structure. If the paper thickness is less than 100 탆, it is preferable from the viewpoint of improvement of softness, but it is difficult to appropriately secure the strength. On the other hand, if it exceeds 250 탆, the coating becomes too hard, which causes deterioration of the feel and stiffness at the time of use.

The thickness of the paper is preferably in the range of 100 to 150 mu m, more preferably in the range of 110 to 140 mu m, particularly in the case of a roll of toilet paper or tissue paper. If it is less than 100 mu m, it is preferable from the viewpoint of improvement of softness, but it is difficult to adequately secure the strength when used as a toilet paper roll or tissue paper. When it exceeds 150 mu m, It is prone to stiffness.

Likewise, in the case of a toilet paper roll or a tissue paper, it is preferable that the paper thickness of the ink applying region is 100 to 200 mu m, preferably 120 to 180 mu m. If it is less than 100 mu m, it is difficult to adequately secure the strength. When it exceeds 200 mu m, the hardness becomes too strong and the stiff feeling at the time of use tends to occur.

The difference between the paper thickness of the chemical solution application area and the paper thickness of the ink application area is preferably 10 to 60 mu m, and more preferably 20 to 50 mu m. This difference in paper thickness is particularly suitable in the case of the paper thickness of each region suitable as the aforementioned toilet paper and tissue paper.

If the paper thickness is less than 10 mu m, there is no difference between the chemical solution application area and the ink application area, and there is no apparent difference in appearance. When the thickness is more than 60 탆, the difference in strength between the liquid-medicating area and the ink-applying area becomes large, which causes deterioration in workability such as breakage of paper at the time of applying the chemical liquid.

As a method of measuring the thickness of each of the above paper sheets, the measurement is carried out using a die roll type gauge (thickness measuring instrument) "PEACOCK G type" (manufactured by Ozaki KK) under the conditions of JIS P 8111. Specifically, it is confirmed that there is no dust or dust between the plunger and the measurement platform, the plunger is placed on the measurement table, the memory of the measurement device is moved to set the zero point, the plunger is then raised, , Makeup paper) is placed on the test stand, and the plunger is slowly lowered to read the gauge at that time. At this time, just put the plunger on. The paper thickness is an average value obtained by performing measurement 10 times.

On the other hand, the sanitary napkin (X1) of the present invention preferably has an elongation percentage of 15 to 35%. When the elongation percentage is less than 15%, or more than 35%, dry wiping becomes difficult. Here, the elongation percentage is determined by measuring the length of the sample immediately before the fracture of the sample, measuring the tensile strength of the sample, and determining the length of the sample relative to the length before measurement Quot; is a value calculated as a ratio. For the measurement, for example, &quot; TG-200N Universal Tensile Compression Tester &quot; manufactured by Minebea Co., Ltd. can be used. The specimen is set to have a width of 25 mm and a length of 150 mm, and a tensile speed of 100 mm / min. The elongation percentage is measured five times each in the longitudinal direction and the lateral direction of the paper, and the elongation percentage is taken as the average value.

On the other hand, the hygienic papermill (X1) of the present invention was measured under a constant temperature and humidity environment with a moisture content of 50% RH and a temperature of 25 ° C. The water content is preferably 4 to 15 wt%. The moisture content is the value measured after 24 hours from leaving the measurement sample in the measurement environment. The moisture content is defined as the moisture content (wt%) = [(weight after humidity adjustment) / Weight) - 1] x 100.

Here, the moisture content may be measured by a moisture meter such as Sanko Electronics, paper and cardboard moisture meter KG-100i.

On the other hand, the sanitary napkin (X1) of the present invention preferably has a crepe number of 10 to 50 / cm. When the number of crepe is less than 10 pieces / cm, the difference in height of the surface is difficult to manifest. If it exceeds 50 pcs / cm, it becomes difficult to produce.

For the crepe, the irregularities are less than 100 mu m, preferably 10 to 70 mu m, and more preferably 15 to 40 mu m. If the irregularity exceeds 100 占 퐉, the feeling of touch becomes worse. If it is less than 10 탆, the spreading of the paper is lost and the performance of wiping is deteriorated.

In addition, it is preferable that the sanitary papermaking sheet of the present invention is grassed so that its crepe ratio is 10 to 30%. Here, the crepe ratio is calculated by (((((peripheral speed of the dryer at the time of paper making) - (reel peripheral speed) / (peripheral speed of the dryer at the time of papping) × 100).

The sanitary napkin (X1) of the present invention described above is manufactured as follows.

The production method of the present invention is characterized in that the application of the ink and the application of the chemical solution are carried out together by the chuck roll. In other words, multicolor printing technology in flexo printing is used. The application of the ink by the related art and the application of the chemical solution in the exclusive region thereof are performed.

More specifically, as shown in Fig. 4, firstly, with respect to the continuous sanitary napkin S drawn out from the original roll, which is not shown, by a chuck roll R1 whose predetermined portion is a convex portion, The ink I is transferred to the region.

In this convex portion, the shape of the transfer surface is a character, a figure, and / or a shape of a pattern, ink is transferred to the continuous hygienic foil paper S in a shape corresponding to the figure, Is provided with a shape portion (P).

Subsequently to the application of the ink (I), a continuous roll (R2) of the continuous sanitary napkin (S) in which the portion corresponding to the convex portion is a concave portion is used to apply at least the ink And the drug solution (C) is transferred and formed to form a region to which only the region and the chemical solution are applied.

In addition, the plate roll (R2) to which the chemical liquid (C) is applied is also a convex portion of the chemical solution applied portion, and therefore the plate is not a concave plate but a convex plate.

Here, in the production method of the present invention, anilox rolls (A1, A2) for transferring the ink (I) and the chemical liquid (C) to the respective plate rolls (R1, R2) Is used.

Here, it is preferable that the number of lines of the chaining plate roll R1 for imparting ink used in the manufacturing method of the present invention is 40 to 100 lines. If the length is less than 40 lines, paper dust enters between convex portions, and there is a high possibility that a figure or the like to be transferred becomes unclear. In addition, even if the number exceeds 100 lines, there is a high possibility that a figure or the like in which paper dust is dried and transferred is unclear.

The anilox roll (A1) for applying the ink to the chucking roll (R1) is a roll of more than 250 lines. More preferably, an anilox roll of 350 lines or more, particularly preferably 400 lines or more is used.

The halftone dot is not particularly limited and may be, for example, in the range of 0.1 to 99%, preferably about 15 to 50%. If it is less than 15%, there is a high possibility that a figure or the like in which paper dust is intercalated and transferred between convex portions becomes unclear. If the content exceeds 50%, there is a high possibility that a pattern or the like transferred with paper dust will become unclear.

In the plate roll R1 for imparting the ink I, the area occupied by the convex portion is preferably 10 to 30%, and the area of the convex portion is preferably 25 to 10000 mm &lt; 2 &gt;. More preferably, the area of the convex portion is 50 to 1000 mm &lt; 2 &gt;.

On the other hand, it is preferable that the tip of the plate roll (R2) for applying the chemical solution used in the production method of the present invention is 40 to 100 lines. If it is less than 40 lines, there is a high possibility that the paper dust is caught between the convex portions and the chemical solution is not sufficiently transferred. In addition, even if the amount exceeds 100 lines, there is a high possibility that the paper powder will be drawn in and the chemical solution will not be sufficiently transferred.

On the other hand, the anilox roll (A2) for applying the chemical liquid to the chucking roll (R2) is a 250 line or more. More preferably, an anilox roll of 350 lines or more, particularly preferably 400 lines or more is used.

The tone of the halftone dot is not particularly limited and may be, for example, in the range of 0.1 to 99%, preferably in the range of 15 to 50%, similarly to the ink roll. On the other hand, if it is less than 15%, there is a high possibility that the paper powder is caught between the convex portions and the chemical liquid is not sufficiently transferred. In addition, when the content exceeds 50%, there is a high possibility that the paper powder is dried and the chemical liquid is not sufficiently transferred.

Further, with respect to the application of the ink and the chemical solution of the present invention, a multi-color printing flexographic printing press can be used as it is. In this case, any of the center drum type and in-line type in the illustrated example can be used, but the center drum type is preferable in that the exclusiveness of the ink application area and the chemical solution application area can be performed with high precision.

The synchro of the inking plate plate roll R1 and the chemical liquid applying plate plate R2 can be performed according to the conventional technique. For example, the roll pressure, the roll position, the distance between rolls, and the working speed are appropriately adjusted in consideration of the diameter of each roll.

Here, the ink (I) used in the present invention is not particularly limited and those used for printing on conventional paper can be used. However, the viscosity is preferably 50 cP or less. When the viscosity exceeds 50 cP, paper dust tends to be easily entangled in the chucking roll, which makes it difficult to print clearly, and work troubles are likely to occur.

As a suitable example, an ink having an effective component (chemical liquid, pigment and resin component) of 5 to 15 mass% and a water content of 70 to 95 mass% can be mentioned. If the ink is of this composition, the ink imparting region of the present invention can be suitably formed.

On the other hand, as the chemical (C) to be used in the present invention, a softener is typical, and in the present invention, at least this is an object and is preferable. Examples of the other chemical liquids include lubricants, bactericides, antiviral agents, and antibacterial agents. These mixed chemicals may be used.

As the softening agent, a cationic surfactant, an anionic surfactant, a nonionic surfactant, or the like can be used. Among them, it is preferable to use a cationic surfactant. As the cationic surfactant, a quaternary ammonium salt, an amine salt, an amine, or the like can be used. As the amphoteric surfactant, an aliphatic derivative of a secondary or tertiary amine containing carboxyl, sulfonate or sulfate or an aliphatic derivative of a heterocyclic secondary or tertiary amine may be used . Examples of the lubricant include fatty acid amide compounds and the like.

Examples of the anionic surfactant include carboxylate salts, sulfonate salts, sulfuric acid ester salts and phosphate ester salts. Among them, alkylphosphoric ester salts are preferable.

Examples of the nonionic surfactant include polyhydric alcohols such as sorbitan fatty acid esters, diethylene glycol monostearate, diethylene glycol monooleate, glyceryl monostearate, glyceryl monooleate, and propylene glycol monostearate. Polyvalent alcohol mono fatty acid esters, N- (3-olylo-2-hydroxypropyl) diethanolamine, polyoxyethylene hydrogenated castor oil, polyoxyethylene sorbitol beeswax, polyoxyethylene sorbitan sesquistearate, Polyoxyethylene monooleate, polyoxyethylene monolaurate, polyoxyethylene cetyl ether, polyoxyethylene lauryl ethyl, and the like can be used.

On the other hand, the kind of the antiviral agent, the antibacterial agent and the fungicide is not particularly limited. For example, plants such as ocimene, camphene, limonene, sabinene, myrcene, terpinene, pinen, cymene, Monoterpene hydrocarbons contained in the extraction component, mono terpene alcohols such as citronelol, geraniol, isopregol, linalol and terpineol, anethole, callback roll, eugenol, Phenols such as thymol, paracresol, carboxy, rosebatex and green tea polyphenol, phenol ethers such as t-anethole, chavicol methyl ether and safflow, acetaldehyde, citral, citronellal , Aldehydes such as geranyl, perylaldehyde and paleranal, ketones such as acetophenone, camphor, jasmon, noton carton, menton, fencon, carbone and furigon, carinoleapinic oxide, cineole, , Catechins, proanthocyanidins, prabones, pravuanones, anthocyanins, phenols, From plastic bonoyi active ingredient Drew, such as bonol may be used by appropriate selection Hi some kind or plural kinds.
