Description

  The present invention relates to a method and an apparatus for manufacturing sanitary thin paper such as toilet paper.

  Conventionally, sanitary thin paper whose surface smoothness, moisture retention and the like are improved by applying a chemical such as a moisturizing liquid or lotion is known. Specifically, for example, in toilet paper, a toilet paper is proposed in which a water-soluble lotion is applied to the entire surface of the sheet, and the touch is good and the stickiness is low (Patent Document 1).

  In addition to the application of a chemical solution, sanitary thin paper is also known in which wiping property, bulkiness, and the like are enhanced by embossing unevenness by embossing a sheet.

  In the manufacturing method of sanitary thin paper coated with these chemicals and embossed, a manufacturing method for embossing a sheet coated with the chemicals (Patent Document 2), or embossing a dry sheet, and then a chemical transfer roll The manufacturing method (patent document 3) etc. which apply | coat a chemical | medical solution is known.

  Moreover, the sanitary thin paper which is hard to collapse can be manufactured by apply | coating a chemical | medical solution only to the predetermined location of a sheet | seat beforehand with the printing machine which apply | coats a chemical | medical solution, and embossing to the part which has not applied the chemical | medical solution. A manufacturing method (Patent Document 4) has also been proposed.

  Furthermore, the embossing process and the chemical application process are performed by applying a chemical to the convex part of the embossing roll at the same time as embossing when applying a chemical to the convex part tip of the embossing roll in advance. There has also been proposed a manufacturing method capable of performing the above in one step (Patent Document 5).

JP 2006-149952 A JP 2009-240721 A Japanese Patent No. 4827409 JP 2012-179071 A Japanese Patent No. 4041209

  However, as in Patent Document 2, when embossing is performed on a sheet coated with a chemical solution, the entire paper becomes soft even though the effect of the chemical solution that improves the touch and the like can be obtained. In some cases, the paper is cut during processing, or the embossing itself may collapse, and the effects of wiping and bulkiness due to the embossing may not be sufficiently obtained.

  Moreover, even if it is a case where a chemical | medical solution is apply | coated with a chemical | medical solution transfer roll after embossing a dry sheet like patent document 3, since a sheet | seat becomes soft by applying a chemical | medical solution, embossing will collapse. Problems arise.

  Further, as in Patent Document 4, if a chemical solution is applied to a part of the sheet and embossed, the embossing can be made difficult to break, but the chemical solution is applied only to a predetermined portion of the sheet. Since a printing machine is required and furthermore, a position where the chemical solution is applied and a position where embossing is applied must be adjusted, labor and cost are required.

  In addition, as in Patent Document 5, a chemical solution is applied to the surface of the convex portion of the embossing roll in advance, and when embossing is performed, the manufacturing method of applying the chemical solution at the convex portion of the embossing roll simultaneously with the embossing processing, Since a chemical | medical solution will be in the state apply | coated only to the recessed part of the embossing, a chemical | medical solution is difficult to touch skin directly and the effect of a chemical | medical solution may not be exhibited well. Furthermore, since the embossing process is performed while the embossing surface is wetted on the surface of the embossing roll, the embossing sheet is softened, and the embossing is easy to break when embossing. The problem of being easily collapsed is not solved.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a sanitary thin paper to which a chemical solution is applied and embossed in a sanitary thin paper manufacturing method. It is to produce sanitary thin paper with high wiping properties and high bulkiness, with less labor and cost, and the embossing is less likely to collapse.

Features.

  According to the present invention, the sanitary thin paper is coated with the chemical solution only in a portion other than the portion to be embossed, so the embossed portion is not wet with the chemical solution, and the paper breakage and the embossing collapse occur during the embossing. Since it becomes difficult, it is possible to manufacture sanitary thin paper without impairing the effect of the embossed part of wiping and bulkiness. Furthermore, it is not necessary to prepare an embossing device and a chemical solution coating device separately, and the embossing step and the chemical solution coating step can be performed simultaneously in one step, so that the manufacturing device can be simplified and the cost can be further reduced. It is possible to manufacture by a method.

Hereinafter, the sanitary thin paper manufactured by this invention and the manufacturing method of sanitary thin paper are demonstrated in detail using drawing.
In addition, although the manufacturing method of a toilet paper is demonstrated as an example of the manufacturing method of the sanitary thin paper in this invention, it is not restricted to a toilet paper, The sanitary thin paper impregnated with chemical | medical solutions, such as a wet tissue and a paper towel, is included.

<Embodiment 1>
The toilet paper 1 manufactured by the method for manufacturing sanitary thin paper of the present invention is coated with a predetermined chemical solution 4 and embossed. When the toilet paper 1 is manufactured, the toilet paper 1 immediately after the embossing is embossed with the chemical solution 4 applied only to a portion other than the portion where the embossing e is applied, as shown in the cross-sectional view of FIG. The portion is manufactured in a state where the chemical solution 4 is not applied.

  The base paper which comprises the toilet paper 1 which concerns on this Embodiment 1 can be manufactured with the papermaking raw material for thin paper which uses raw material pulp as a main raw material, and has water disintegration property. The raw material pulp is not particularly limited, and an appropriate raw material pulp can be selected according to the specific use of the sanitary thin paper, and can be used by appropriately blending.

  Examples of raw material pulp include wood pulp, non-wood pulp, synthetic pulp, waste paper pulp, and more specifically, groundwood pulp (GP), stone grand pulp (SGP), refiner ground pulp (RGP), pressure type Mechanical pulp (MP), chemical mechanical pulp (CGP), semi-chemical pulp (such as ground pulp (PGW), thermomechanical pulp (TMP), chemithermomechanical pulp (CTMP), bleach chemithermomechanical pulp (BCTMP) Kraft pulp (KP) such as SCP), hardwood bleached kraft pulp (LBKP), softwood bleached kraft pulp (NBKP), and unbleached pulp, soda pulp (AP), sulfite pulp (SP), dissolved pulp (DP) Chemical pulp (CP), nylon, rayon, polyester , Synthetic pulp made from polyvinyl alcohol (PVA), deinked pulp (DIP), waste pulp such as waist pulp (WP), ground pulp (TP), cotton, flax, hemp, jute, manila hemp, ramie, etc. One kind or several kinds of auxiliary pulps such as rag pulp, straw pulp, esparto pulp, bagasse pulp, bamboo pulp, kenaf pulp, and other auxiliary pulps such as bast pulp can be appropriately selected and used.

  In particular, the raw material pulp is preferably a blend of NBKP and LBKP. Waste paper pulp may be blended as appropriate, but it is preferably composed only of NBKP and LBKP in terms of texture and the like, and the blending ratio in that case is NBKP: LBKP = 10: 90 to 50:50. In particular, NBKP: LBKP = 40: 60 is desirable.

  Raw materials such as raw material pulp are used as raw paper through, for example, a known paper making process, specifically, a wire part, a press part, a dryer part, a size press, a calendar part, and the like. When making paper, for example, a suitable chemical such as a pH adjuster such as a dispersant, caustic soda, or aqueous ammonia, an antifoaming agent, an antiseptic, a fluorescent dye, a mold release agent, a water-resistant agent, a flow modifier, and a yield improver Can be added.

The rice paper weight of the toilet paper 1 can be adjusted as appropriate depending on the application, but it is desirable to use a paper weight of 1 to 25 g / m ² per ply. When the rice tsubo is less than 10 g / m ² , it is preferable from the viewpoint of improving the softness, but the embossed e is liable to collapse and it is difficult to ensure adequate strength that can withstand use. On the other hand, when the rice tsubo is larger than 25 g / m ² , the entire paper becomes hard, a feeling of stickiness is generated, the touch is poor, and the water disintegration property is deteriorated. In addition, as a measuring method of US tsubos, the method according to JISP8124 etc. are mentioned, for example.

  The paper thickness of the toilet paper 1 is measured by a dial thickness gauge (thickness measuring instrument) “PEACOCK G type” (manufactured by Ozaki Seisakusho), and the paper thickness is in the range of 100 to 300 μm with 2 plies. Is desirable. When the thickness is less than 100 μm, the sense of thickness as a product is insufficient, the paper is easily stretched, and the paper is easily cut during embossing. If it is thicker than 300 μm, the feeling of use is bad and the feeling of use becomes worse, and the impregnation with the chemical solution may be insufficient.

  The dry tensile strength (according to JIS P8113) of the toilet paper 1 is 60 to 150 cN / 25 mm in the dry tensile strength in the direction perpendicular to the feeding direction of the toilet paper 1 (2-ply) from the raw roll, that is, in the transverse direction. It is desirable that the dry tensile strength in the direction parallel to the feeding direction from the raw roll of the toilet paper 1, that is, the longitudinal direction is 180 to 350 cN / 25 mm. When the above strength is not achieved, the paper may be easily cut during embossing and the workability may be deteriorated. When the strength exceeds the above strength, the touch after applying the chemical may be deteriorated.

  The chemical solution component applied to the toilet paper 1 is an oil-based chemical solution containing oil as a main component, for example, a chemical solution of 100% oil, and 3 to 400% by weight (preferably 10 to 10%). 80% by weight). Specific types of oil include liquid oil, mineral oil such as petroleum jelly, jojoba oil, argan oil, cocoon oil, macadamia nut oil, olive oil, apricot kernel oil, avocado oil, evening primrose oil, wheat jam oil, Vegetable oils such as carrot oil, cucumber nut oil, grape seed oil, coconut oil, sweet almond oil, sesame oil, St. John's wort oil, peach kernel oil, hazelnut oil, borage oil, and rosehip oil can be used.

  Since the chemical liquid 4 can maintain the paper strength more strongly than the case where the aqueous chemical liquid 4 is used by using the oil-based chemical liquid 4 whose main component is oil, the aqueous chemical liquid 4 is applied. Compared to the case, the emboss e can be made difficult to collapse, and the effect of the emboss e such as wiping property and bulkiness can be improved.

  In addition, when apply | coating the oil-type chemical | medical solution 4, a sticky feeling may become a problem as a feeling of use, but as described in the manufacturing method mentioned later, the location which applies the chemical | medical solution 4 is set to locations other than an embossing part. Since it can restrict | limit and the chemical | medical solution application amount can also be restrict | limited, a sticky feeling can be suppressed by adjusting the chemical | medical solution amount to apply | coat.

  As described above, it is desirable to apply the oil-based chemical solution 4 containing oil as a main component. However, a chemical solution generally used in an aqueous chemical solution, for example, an aqueous lotion containing 70 to 90% glycerin as a polyol. It is good also as manufacturing using the aqueous | water-based chemical | medical solution 4 containing the solution etc.

  In addition, as described above, the toilet paper 1 manufactured in the present invention is applied with the chemical solution 4 only in a portion other than the portion to which the emboss e is applied at the time of manufacture. It spreads over the entire plane. However, since it diffuses slowly over time, the emboss e is not collapsed more than necessary, and the wiping property and bulkiness of the emboss e can be maintained during use. Of course, depending on the viscosity and amount of the chemical solution 4 to be applied, the chemical solution 4 may not be diffused in the portion where the embossing e is applied, and the chemical solution is applied in the portion where the embossing e is applied and other portions. It is also possible to adopt a mode in which the amount of impregnation is different.

  Next, the manufacturing method of the toilet paper 1 which concerns on this invention is demonstrated.

  As shown in FIG. 2, the toilet paper 1 in the present invention is manufactured by simultaneously performing embossing and chemical coating using a gravure printing method on a base paper 11 fed from a raw roll 10. More specifically, in the manufacturing method of the first embodiment, the embossing roll 2 is immersed in the chemical solution 4, the chemical solution supplying step of supplying the chemical solution 4 to the concave portion of the embossing roll 2, and the amount of the chemical solution by the air knife 5 and the blade 6. A series including a chemical liquid application amount adjusting process to be adjusted, and an embossing process in which the base paper 11 fed from the raw roll 10 is passed between the embossing roll 2 and the elastic roll 3 to perform embossing and simultaneously apply chemical liquid. And is wound as a secondary raw roll 20.

  Here, as shown in FIG. 3A, the embossing roll 2 used in the first embodiment is a coating that can impart water / oil repellency to the tip 2a of the convex portion of the embossing roll 2, for example, fluorine. It is coated with a resin or the like and repels the oil-based chemical solution 4 mainly composed of the oil described above.

Moreover, the preferable form of the embossing roll 2 in this Embodiment 1 is that the convex part in the embossing roll 2 has an area ratio of 5 to 50% (particularly preferably 10 to 25%) with respect to the roll surface, and the convex part of one convex part. The surface area is 1 to 16 mm ² (particularly preferably 1 to 4 mm ² ), the emboss density of the convex part is 1 to 15 pieces / cm ² (particularly preferably 5 to 14 pieces / cm ² ), and the convex part depth is 0. It is desirable that the thickness is 0.5 to 4.0 mm (particularly preferably 1.0 to 2.0 mm). If the embossing e is less than 1 mm ² , the embossing e is small and it is difficult to obtain the effect of wiping off the embossing e. If the embossing e is larger than 16 mm ² , the embossing e tends to collapse and it is difficult to obtain the bulky effect. Further, when the emboss density is less than 1 piece / cm ² , the number of the emboss density is small, and thus the effect of the emboss e is difficult to obtain. When the emboss density is 15 pieces / cm ² , the place where the chemical solution 4 is applied (emboss e Less part). Further, if the depth is less than 0.5 mm, it is difficult to obtain the effect of wiping off and bulkiness of the emboss e, and if it is greater than 4.0 mm, it becomes easy to break the paper when the emboss e is applied.

  Further, the shape of the embossed e is desirably a form in which the supplied chemical solution 4 is difficult to flow down from the embossing roll 2. For example, it is desirable that the flat surface of the embossed convex portion be a square shape. However, since it is possible to adjust the difficulty of flow of the chemical solution 4 depending on the rotational speed of the embossing roll 2 and the viscosity of the oil to be used, there is no particular limitation as long as the shape can be applied by the embossed recess. The shape of e can be selected as appropriate.

Subsequently, each step will be described in more detail.
First, the chemical solution supplying step is a step of supplying the chemical solution 4 to the concave portion of the embossing roll 2 by rotating the embossing roll 2 while immersing it in the chemical solution 4.

  Next, in the chemical solution application amount adjusting step, the chemical solution amount in the recesses of the embossing roll 2 is adjusted by removing the excess chemical solution 4 with the air knife 5 and the blade 6 from the embossing roll 2 after passing through the chemical solution 4. This is a step of adjusting the amount of the chemical solution to be left and applied. The air knife 5 can scrape excess chemical solution 4 by blowing compressed air, and the blade 6 can scrape excess chemical solution 4 directly with a thin metal or ceramic blade. It is possible to adjust and equalize the amount. And since the front-end | tip part 2a of the convex part of the embossing roll 2 is coated with the fluororesin as mentioned above and has oil repellency, it peels off the chemical | medical solution 4 which has oil as a main component, FIG.3 (b) Thus, it can be set as the state by which the chemical | medical solution 4 was supplied only to the recessed part of the embossing roll 2. FIG.

  Next, in the embossing process, embossing and chemical solution application are performed simultaneously by passing the base paper 11 fed out from the raw fabric roll 10 between the embossing roll 2 and the elastic roll 3. In the stage before the embossing process, as shown in FIG. 3B, since the chemical solution 4 is supplied only to the concave portion of the embossing roll 2, the timing for embossing is shown in FIG. Thus, the chemical | medical solution 4 can be apply | coated only to parts other than the location which performs embossing.

  This Embodiment 1 is implemented by repeating the series of steps described above, that is, the chemical solution supply step, the chemical solution application amount adjustment step, and the embossing step, and the toilet paper 1 can be manufactured continuously. Therefore, even if the chemical solution 4 remains in the recess of the embossing roll 2 when the chemical solution application is completed, it can be used in the next cycle, so that it is necessary to apply all of the chemical solution 4 supplied to the recess. There is no need to discard the remaining chemical 4.

In addition, since the front-end | tip part 2a of the convex part of the embossing roll 2 has not only oil repellency but water repellency by coating with a fluororesin, it is a case where the chemical | medical solution 4 is made into an aqueous | water-based chemical | medical solution, for example. In addition, the chemical solution 4 can be supplied only to the concave portion of the embossing roll 2.
Moreover, the coating of a convex part is not restricted to the coating by a fluorine resin, If it is a processing method which has the same effect, it can select suitably. Further, in the first embodiment, coating with a material having only oil repellency may be performed by applying a chemical solution using the oil-based chemical solution 4, or by coating with a material having only water repellency. The chemical solution 4 may be applied.

  In the first embodiment, the amount of the chemical applied is adjusted using the air knife 5 and the blade 6. However, as long as the same effect can be obtained, the method is not particularly limited and can be appropriately changed. Is possible.

  In the first embodiment, the chemical solution 4 is supplied to the embossing roll 2, and the embossing roll 2 is directly immersed in the chemical solution 4. However, the configuration is particularly limited as long as the chemical solution 4 can be supplied. For example, it is good also as supplying the chemical | medical solution 4 provided to the elastic roll to the recessed part of the embossing roll 2 via the elastic roll.

<Embodiment 2>
Next, the manufacturing method of the toilet paper 1 in other embodiment is demonstrated using FIG. In addition, about the following description of Embodiment 2, it demonstrates centering around difference with the manufacturing method of the toilet paper 1 of Embodiment 1, the same code | symbol is provided to the same structure, and description is abbreviate | omitted.

  In the manufacturing method of the second embodiment, an oil-repellent liquid 9 (for example, a liquid containing water, a pigment, or a dye) supplied from the doctor chamber 7 is applied to the surface of the embossing roll 2 via the anilox roll 8. It has the coating process of the convex part of the embossing roll 2 to provide. And after a coating process, it has a series of manufacturing processes including a chemical | medical solution supply process, a chemical | medical solution application amount adjustment process, and an embossing process similarly to Embodiment 1. FIG.

As shown in FIG. 5 (b), the embossing roll 2 is coated with the oil repellent liquid 9 supplied from the doctor chamber 7 on the surface of the tip of the embossing roll 2 and the anilox roll 8. It is the process of providing through. As shown in FIG. 5 (c), the surface of the tip of the convex portion of the embossing roll 2 can be covered with the oil-repellent liquid 9 by the coating process, so that the surface of the tip of the convex portion repels the oil-based chemical solution 4. Be able to.
In addition, since the coating process replaces the oil repellency function obtained by coating with the fluororesin of the first embodiment, unlike the first embodiment, it is necessary to coat the convex portion of the embossing roll 2 with the fluororesin. Absent.

Next, the chemical solution 4 is supplied to the concave portion of the embossing roll 2 by immersing the embossing roll 2 in the oil-based chemical solution 4 in the chemical solution supplying step, and the air knife 5 and the blade 6 are used to adjust excess amount in the chemical solution application amount adjusting step. By removing the chemical solution 4, a predetermined amount of the chemical solution 4 remains in the recess of the embossing roll 2 as shown in FIG.
Note that the oil repellency liquid 9 applied in the coating process can also be removed by the air knife 5 and the blade 6. Here, even if the oil-repellent liquid 9 remains on the surface of the convex portion or flows into the concave portion by the air knife 5 and the blade 6, the oil-repellent liquid 9 on the surface of the convex portion is extremely polar. Since the amount is very small, no particular problem occurs.

  Next, in the embossing process, embossing and chemical solution application are performed simultaneously by passing the base paper 11 fed out from the raw fabric roll 10 between the embossing roll 2 and the elastic roll 3. In the stage before embossing, as shown in FIG. 5 (d), since the chemical solution 4 is supplied only to the concave portion of the embossing roll 2, as shown in FIG. And the chemical | medical solution 4 will be apply | coated only to parts other than the location which embosses.

  As described above, the oil-repellent liquid 9 applied to the convex portion of the embossing roll 2 can be water or a liquid containing a pigment / dye, but is not particularly limited as long as it repels oil. Absent. If water-repellent liquid, not oil-repellent, is applied to the convex portion of the embossing roll 2, it is possible to use water-based chemical liquid 4 instead of oil-based.

As described above, according to the toilet paper manufacturing method of the present invention, the embossed e is applied to the base paper 11 fed out from the raw fabric roll 10 and at the same time, the chemical solution 4 is applied only to a portion other than the portion where the embossed e is applied. Can be applied. In the conventional method of embossing e on a sheet that has already been coated with the chemical solution 4, the embossing e is performed on a sheet that has been weakened in paper strength because the chemical solution has been applied. The problem is that the embossing e tends to collapse. In contrast, according to the present invention, the portion of the sheet to which the embossing e is applied is in a dry state, and the chemical solution can be applied to a portion other than the embossed portion. It has become difficult. Therefore, it is possible to sufficiently obtain the effect of embossing e such as wiping property and bulkiness.
In addition, since the embossing process and the chemical solution coating process can be carried out simultaneously in one process, it is not necessary to prepare an embossing device and a chemical solution coating device separately, and the manufacturing apparatus can be made simple, thereby further reducing costs. It is possible to manufacture by the method.
