Abstract
A household tissue paper is formed by laminating a plurality of base papers, and can prevent layer peeling and sheet distortion even in a state that a sheet is wet by coating a chemical solution. In a household tissue paper obtained by laminating 2 or more sheets of base paper, embossing (e1) is performed in which a cut part (4) is formed by a shear force during embossing. By performing embossing (e1) having a cut section (4), the base papers can be bonded more firmly to each other than by normal embossing, and therefore, even in a wet state in which a chemical solution is applied to the sheet, peeling of the layers and twisting of the sheet can be prevented.
Description
Technical Field
The present invention relates to a household tissue, an embossing device, and a method for producing household tissue.
Background
Conventionally, household tissue paper such as toilet paper and kitchen paper is generally used which is formed by laminating a plurality of sheets of base paper such as crepe paper to form 1 sheet in order to improve the hand feeling, absorbency, bulk, and the like. In order to prevent the delamination of the sheets formed by the lamination process, a method of integrating the sheets by embossing or bonding with an adhesive is often performed.
Specifically, for example, there are known a laminate of thin paper obtained by embossing with high bonding strength (see patent documents 1 and 2) and a sheet obtained by providing edge embossing at both side edges of the sheet (see patent documents 3 and 4). Further, there is known a tissue paper obtained by joining sheets with a water-soluble adhesive in addition to embossing (see patent document 5).

Disclosure of Invention
In a household tissue paper obtained by laminating a plurality of base papers, the sheets are subjected to embossing or adhesive in a dry state, thereby effectively preventing layer separation. However, in a state where a sheet is wetted by applying a predetermined chemical solution or the like, the effect of embossing cannot be sufficiently obtained, and even at a portion subjected to embossing, problems such as layer peeling and sheet warping still occur.
In addition, in the method using a water-soluble adhesive, the adhesive may dissolve in a chemical solution and the effect of the adhesive may not be sufficiently obtained, or the flexibility and bulkiness of the sheet may be impaired by the adhesive. In addition, when the adhesive is additionally applied to the embossing, the operation and cost for additionally applying the adhesive are more burdensome than those in the case of only performing the embossing.
The present invention has been made in view of the above problems, and an object of the present invention is to prevent layer separation and sheet distortion even when a sheet is wet by applying a chemical solution to a household tissue paper in which a plurality of raw paper layers are laminated.
In order to solve the above problems, the invention according to claim 1 is a household tissue paper obtained by laminating 2 or more sheets of base paper,
has a cut portion formed by a shearing force at the time of embossing.
The invention described in claim 2 is the household tissue described in claim 1, characterized in that,
a folding and overlapping working part for forming a crease line during folding processing,
in the cutting part, the cutting length of the 1 st cutting part arranged in the folding and overlapping working part is longer than that of the 2 nd cutting part arranged in the part except the folding and overlapping working part.
The invention described in claim 3 is the household tissue described in claim 1, characterized in that,
both side edge portions of the household tissue are pressed by the embossing having the cutting portion.
The invention described in claim 4 is an embossing apparatus for producing the household tissue paper described in any one of claims 1 to 3, characterized in that,
having an upper side emboss roller and a lower side emboss roller provided at opposite positions,
the convex portion of the upper emboss roller and the convex portion of the lower emboss roller do not overlap each other,
when the upper emboss roller and the lower emboss roller are used to perform the embossing by squeezing in a state where 2 or more sheets of base paper are stacked, the household tissue paper is broken by a shearing force generated between the convex portion of the upper emboss roller and the convex portion of the lower emboss roller, and the cut portion is formed.
The invention described in claim 5 is the embossing processing apparatus for manufacturing household tissue according to claim 4, characterized in that,
the shape of the emboss formed by the convex part is hexagonal.
The invention described in claim 6 is the embossing processing apparatus for manufacturing household tissue according to claim 4, characterized in that,
the pattern of the protrusions of the upper emboss roller and the pattern of the protrusions of the lower emboss roller are the same.
The invention described in claim 7 is a method for producing household tissue paper by using the embossing apparatus described in claim 4, characterized in that,
when the upper emboss roller and the lower emboss roller are used to perform the embossing by squeezing in a state where 2 or more sheets of base paper are stacked, the household tissue paper is broken by a shearing force generated between the convex portion of the upper emboss roller and the convex portion of the lower emboss roller, and the cut portion is formed.
According to the present invention, by performing embossing in which cuts are formed on a plurality of overlapped base papers, the base papers can be bonded more firmly to each other than by normal embossing. Therefore, even in a wet state where the sheet is coated with the chemical solution, peeling of the base paper and twisting of the sheet can be prevented. Further, the emboss with cut is natural to obtain the effects of softness, bulkiness, etc. obtainable in the usual emboss without cut, and there is almost no difference in appearance even if cut is formed, and therefore the beauty of the product is not impaired. Further, since it is preferable to form the cuts simultaneously with the embossing, it is not necessary to add a separate process.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The scope of the invention is not limited to the examples of the figures.
In the household tissue paper and the method for producing the household tissue paper pertaining to the present invention, the household tissue paper will be described by taking toilet paper as an example. Further, the longitudinal direction of the toilet cleaning paper is defined as an X direction, the short side direction of the toilet cleaning paper is defined as a Y direction, and a direction perpendicular to the plane of the toilet cleaning paper is defined as a Z direction.
The toilet cleaning paper 1 manufactured according to the present embodiment is formed by laminating (ply) a plurality of base papers, and is coated with a predetermined chemical solution. As shown in fig. 1(a), the entire surface of the sheet of toilet paper 1 is embossed, and cut portions 4 are provided for each embossing. Further, as shown in fig. 1(b), the toilet cleaning paper 1 is folded in two at the center in the longitudinal direction (X direction) by folding. In addition, the film is stored in a plastic casing or a packaging film for storage in a folded state, and is unfolded for use as needed. The folding manner of the toilet paper 1 is not limited to the double folding, and may be 4 or 8, for example.
The toilet cleaning paper 1 of the present embodiment is made of a hydrolytic fiber aggregate so that the toilet cleaning paper can be directly discarded in a sink of a toilet after cleaning the toilet. The fiber aggregate is not particularly limited as long as it is a fiber aggregate having hydrolyzability, and natural fibers, synthetic fibers, fibers obtained by mixing these fibers, and the like can be used. Preferable raw material fibers include cellulose fibers such as wood pulp, non-wood pulp, rayon and cotton, biodegradable fibers made of polylactic acid, and the like. In addition, polyvinyl alcohol (PVA), carboxymethyl cellulose (CMC), or the like as a paper strength agent may be blended, coated, or coated in order to improve the strength of the base material.
The toilet paper 1 of the present embodiment is coated with a predetermined chemical solution, specifically, a predetermined chemical solution containing an auxiliary agent such as a perfume, an antiseptic, a bactericide, and a paper strength enhancer in addition to an aqueous cleaning agent. As the chemical solution, a suitable chemical solution can be used, for example, as an aqueous cleaning agent, and a lower or higher (aliphatic) alcohol can be used in addition to the surfactant. As the perfume, in addition to water-based perfumes, one or more kinds of oily perfumes such as orange oil can be suitably selected and used. As the preservative, for example, parabens such as methylparaben, ethylparaben and propylparaben can be used. As the bactericide, alcohol, paraben, monomeric quaternary ammonium salt, cetylpyridinium chloride, phenoxyethanol, etc. can be used. As the paper strength enhancer, boric acid, various metal ions, and the like can be used.
The component auxiliary agents of the above-mentioned chemical solutions can be appropriately selected, and components that exert other functions can be contained in the chemical solutions as needed.
As shown in fig. 1, the embossments e1 are applied to the entire surface of the toilet paper 1, and each embossment e1 has a cut portion 4. Specifically, as shown in the cross-sectional view of fig. 2, a part of the portion where the embossing e1 is performed is cut to form the cut portion 4, and the cut portion 4 is entangled with the fibers in the vicinity of the cut portion 4. Therefore, the stacked sheets are less likely to be displaced than in the case where the cut portions 4 are not provided.
In addition, the embossing e1 having the cut portions 4 can also obtain a normal embossing effect, and can improve the hand, absorbency, bulk, and the like of the toilet paper. Further, since the shape of the cut portion 4 is inconspicuous, the same effect as that of ordinary embossing can be obtained by embossing.
Next, a method for manufacturing the toilet cleaning paper 1 according to the present embodiment will be described.
The toilet cleaning paper 1 of the present embodiment is manufactured by a series of manufacturing methods including: an embossing step (S1) for embossing the laminated sheet 3 with a cut portion; and a finishing step (S2) for folding by folding, applying the chemical solution, and packaging.
First, the embossing process (S1) will be described in detail with reference to fig. 3. The direction in which the laminated sheet 3 is pulled out is referred to as the X direction, the direction orthogonal to the direction in which the sheet is pulled out on the sheet surface is referred to as the Y direction, and the direction orthogonal to the sheet surface (XY plane) is referred to as the Z direction.
In the embossing step (S1), as shown in fig. 3, the laminated sheet 3 drawn from the winding roll 2 subjected to the laminating process is embossed by the embossing device 100.
The embossing apparatus 100 is an apparatus for forming an embossment e1 having a cut portion 4 by using an upper embossing roll 10 and a lower embossing roll 20. The upper emboss roller 10 and the lower emboss roller 20 are respectively provided at opposite positions, and the roller surfaces have the same concavo-convex pattern. The raised portions 11 on the surface of the upper emboss roller 10 and the raised portions 21 on the surface of the lower emboss roller 20 are arranged so as to be shifted in the XY direction so as not to overlap each other at the time of embossing, as will be described later.
An example of the concave-convex pattern on the surface of the upper emboss roller 10 will be described with reference to fig. 4(a), (b), and (c). Here, the number of layers of the laminated sheet 3 to be embossed may be appropriately changed as long as it is a sheet having 2 layers or more, and in the following description, a case of 2 layers will be described as an example.
As shown in an example of fig. 4(a), the upper emboss roller 10 has a surface provided with projections 11 having a hexagonal cross section in the XY direction. The hexagonal shape is a hexagon as follows: the internal angle α 1 of each hexagon is, for example, 95 to 175 degrees and is line-symmetric with respect to a straight line parallel to the Y direction passing through the center. Here, the length d1 of each of the 2 sides parallel to the Y direction is, for example, 0.5 to 2.5mm, and the distance d2 between the 2 sides is, for example, 0.5 to 2.5 mm. The convex portions 11 provided on the roller surface were provided at intervals of about 1 convex portion degree in the Y direction, and the same row was provided at intervals of about 1.5 convex portions degree in the X direction and about 0.5 convex portion degree in the Y direction. Then, the 2 rows are repeatedly arranged to constitute a convex pattern of the roller surface.
In addition, as shown in fig. 4(b), the cross section of the protrusions 11 on the surface of the emboss roller has a rectangular shape with an angle α 2 of 90 degrees, for example, and a height h1 of 1.0 to 2.0mm, for example, in the XZ direction. Further, as shown in fig. 4(C), the YZ-direction cross section is a trapezoid having an upper bottom side 2 angle α 3 of 106 degrees, for example, and a height h1 of 1.0 to 2.0mm, for example.
As shown in fig. 3, the upper emboss roller 10 and the lower emboss roller 20 are provided at positions opposed to each other in the Z-axis direction, and are arranged as follows: when the upper emboss roller 10 and the lower emboss roller 20 are overlapped, the respective convex portions do not overlap (see fig. 5). Specifically, as shown in the enlarged view of fig. 5 in fig. 6, the distance s1 in the X direction between the protrusions 11 of the upper emboss roller 10 and the protrusions 21 of the lower emboss roller 20 is, for example, 0.1 to 0.5mm, and the displacement d3 in the Y direction is, for example, 0.1 to 2.0mm, and the protrusions are arranged in parallel with each other on the 2 sides in the Y direction. Further, the vicinity of the side surface in the Y direction where the convex portion 11 of the upper emboss roller 10 and the convex portion 21 of the lower emboss roller 20 face each other becomes the cutting position 5.
The overlap d4 in the Y direction of the projections 11 of the upper emboss roller 10 and the projections of the lower emboss roller 20 in the cutting position 5 is, for example, 0.4 to 2.4 mm. The distance s1 in the X direction between the protrusions 11 of the upper emboss roller 10 and the protrusions 21 of the lower emboss roller 20 is, for example, 0.1 to 0.5mm as described above, but may be changed as long as the distance is a distance that the sheet is sandwiched and broken by a shearing force as described below.
As shown in fig. 7, the protrusions 11 of the upper emboss roller 10 and the protrusions 21 of the lower emboss roller 20 are configured such that the sheet can be sandwiched between the side surfaces in the Y direction where the protrusions face each other. The cut portions 4 generated when embossing are troublesome as follows: when the sheet is pressed by the emboss roller, the sheet is sandwiched between the protrusions 11 of the upper emboss roller 10 and the protrusions 21 of the lower emboss roller 20, and the portion of the sheet at the cutting position 5 between the protrusions receives a load, and the sheet is broken by a shear force.
The cutting length of the cutting portion 4 can be appropriately changed by changing the size of the projection itself, but the cutting length can be adjusted without changing the size of the projection itself. Specifically, the cutting length can be adjusted by changing the displacement distance of the protrusions in the Y direction, and as shown in fig. 8, when the protrusions are not displaced in the Y direction, the length of the cut position 5 of the side surface of the upper emboss roller 10 where the protrusions 11 oppose the protrusions 21 of the lower emboss roller 20 becomes longest, and the cut length can be extended. Further, as shown in fig. 9, when the projections 21 are displaced in the Y direction to shorten the length of the side surfaces of the projections facing each other, the length of the cutting position 5 is shortened, and the cutting length can be shortened.
In the above-described embodiment, the example was described by taking the case where the protruding portion of the emboss roller is formed into a hexagonal shape having an appropriate length, but the size of the protruding portion may be changed as appropriate, the shape may be a square or a pentagon, and the size of the protruding portion is not limited to the above-described example.
The convex portion of the present embodiment may be disposed by being rotated at an appropriate angle. For example, if the protrusions 11 and 21 of the upper and lower emboss rollers 10 and 20 are provided by rotating each by 90 degrees, the orientation of the cut portions 4 can be set in a direction parallel to the X direction, and if the protrusions are provided by rotating by 45 degrees, the orientation of the cut portions 4 can also be set in a direction rotated by 45 degrees.
In the present embodiment, the protrusions 11 of the upper emboss roller 10 and the protrusions 21 of the lower emboss roller 20 are all made of the same pattern, but they are not necessarily the same. Specifically, the convex portions 11 of the upper emboss roller 10 may be formed in a hexagonal shape and the convex portions 21 of the lower emboss roller 20 may be formed in a quadrangular shape, for example, as long as the sheet can be broken by the shearing force at the cutting position 5.
After the embossing step (S1), a finishing step (S2): folding by folding processing, coating the medicinal liquid, and packaging. Specifically, the method comprises the following steps: after the embossing (S1), the toilet paper 1 is cut into 1 sheet, folded into an appropriate size, coated with an appropriate chemical, and packaged, thereby completing the toilet paper 1.
Each step of the finishing step (S2) may be added or omitted as necessary, and for example, a step not including folding or applying a chemical solution may be included.
Next, the conventional toilet paper embossed without cuts and the toilet paper embossed with cuts of the present embodiment were evaluated for workability, appearance, distortion difficulty, and layer peeling difficulty, and evaluation results are described (see table 1).
TABLE 1
< implementation conditions >
Base paper: paper pulp 100% (matching PVA fiber)
Weighing (stacked state): 90g/m2(2 layer)
Embossing conditions: the embossing of the present embodiment is performed in such a manner that d1 is 1.45mm, d2 is 1.2mm, d3 is 0.48mm, d4 is 0.97mm, s1 is 0.3mm, h1 is 1.6mm, α 1 is 120 degrees, α 2 is 90 degrees, and α 3 is 106 degrees.
Embossing density: about 8 pieces/cm2
The medicinal liquid (experiment 2) comprises ethanol, surfactant, degerming agent, orange extract, and organosilicon
First, as an experiment (1), the workability of the laminated sheet 3 was evaluated at the time of folding in the finishing step (S2) of the toilet paper 1. In the folding process, since the toilet paper 1 is in a dry state because the embossing is performed as described above but the chemical is not applied.
In the evaluation of workability, whether or not layer dislocation occurred during machining was evaluated (the case where dislocation occurred was evaluated as "x", and the case where dislocation did not occur was evaluated as "o"). As shown in table 1, when only non-cut embossing was performed, layer displacement occurred in some cases, making it difficult to process, and when cut embossing was performed, layer displacement did not occur, making it easy to process.
Next, as experiment (2), when the toilet paper 1 was used as a finished product, the appearance, distortion, and layer peeling were evaluated organoleptically. As shown in the present embodiment, the toilet paper 1 was wet by being coated with the chemical solution, and evaluated on the assumption that it was used.
In the evaluation of the appearance, whether or not the sheet was broken and the appearance was deteriorated was evaluated (the case where the sheet was broken was evaluated as "x", and the case where the sheet was not broken was evaluated as "o"). As shown in table 1, when only the non-cut embossing was performed, the sheet broke and the appearance was deteriorated, and when the cut embossing was performed, the sheet did not break and the appearance was maintained.
In the evaluation of the distortion, whether or not the sheet was distorted was evaluated (the case where the sheet was distorted was evaluated as "x", and the case where the sheet was not distorted was evaluated as "o"). As shown in table 1, when only non-cut embossing was performed, the sheet was easily twisted, and when cut embossing was performed, the sheet was not easily twisted.
In the evaluation of layer peeling, whether the folded sheet could be satisfactorily unfolded without layer peeling occurring was evaluated (evaluated as "x" if layer peeling occurred upon unfolding, and evaluated as "o" if layer peeling did not occur). As shown in table 1, when only non-cut embossing was performed, the sheet was delaminated, and the sheet could not be satisfactorily developed.
In this way, when the embossing process having the cut portions 4 is performed, the joining force between the sheets is increased, so that the processing is easy in the manufacturing process, and a remarkable effect of being beautiful, less likely to twist, and less likely to peel the layer when the product is used can be obtained.
< modification 1>
In the present embodiment, as shown in fig. 10, an embossed pattern e2 having a cut portion 6 with a long cut length may be applied to the folded portion. Specifically, for example, as shown in fig. 1(b), when the center portion in the longitudinal direction of the toilet paper 1 is folded into two, the embossing e2 having the long-cut part 6 may be formed only in the center portion in the longitudinal direction. In this case, since the central row having a long cut length is easily creased, the folding process is facilitated.
Here, as described above, the cut length may be adjusted by shifting the convex portion of the emboss roller in the Y direction, or may be adjusted by increasing the size itself of the convex portion of the emboss roller.
The example in which the long-cut portions 6 are arranged in the row 1 only in the center portion in the longitudinal direction of the toilet paper 1 in the Y direction orthogonal to the longitudinal direction has been described, but the present invention is not limited to this, and the long-cut portions 6 may be arranged in 2 rows or more, or the long-cut portions 6 may be arranged in the X direction.
Although the same effect as in modification 1 can be obtained by providing the perforation lines, this embodiment is advantageous in that the cuts can be formed simultaneously with the embossing, and therefore, additional steps and costs are not required.
< modification 2>
As shown in fig. 11, the embossing having the cut portions 4 of the present embodiment may be implemented as edge embossing e3 of both side edge portions of the sheet. Here, the orientation of the cut portions 4 can be appropriately changed by changing the direction of the convex portions on the surface of the emboss roller, and fig. 11 shows, as an example, a case where the side surfaces of the convex portions of the present embodiment are rotated by 90 degrees with respect to the Y direction.
The edge embossing e3 is formed by pressing both side edge portions of the sheets to each other, and can prevent the layer from peeling. By forming the edge embossing e3 having the cut portions 4 by the method of the present embodiment, the effect of edge embossing, that is, the delamination resistance, can be further improved.
As described above, the toilet paper of the present embodiment is manufactured by performing the embossing process (S1) of the emboss e1 having the cutting part 4 and the finishing process (S2) of the folding process, the chemical coating process, and the packaging process. Further, since the toilet paper sheets are firmly joined to each other by the emboss e1 having the cut portion 4, even if the sheets are coated with the chemical, the sheets can be prevented from being peeled off and twisted.
Further, the cut-forming embossments of the present invention naturally provide the effects of softness, bulkiness, and the like obtainable by ordinary non-cut embossments, and moreover, there is little difference in appearance even when cut is formed, and therefore, the beauty of the product is not impaired. Further, since the cuts can be formed simultaneously with the embossing, an additional process is not required.
Note that, although the present embodiment has been described using toilet paper as an example, the present invention also includes household tissue paper such as kitchen cleaning paper used in a state where base paper is laminated and coated with a chemical solution. Further, household tissue paper such as toilet paper and tissue paper used in a dry state may be embossed with a cut portion, or may be non-hydrolyzed paper as well as hydrolyzed paper.
In the present embodiment, the lamination processed sheet is subjected to embossing for forming cuts, but the present invention is not limited to this, and lamination and embossing may be performed simultaneously at the stage of lamination processing.
In the method for producing toilet paper according to the present embodiment, a method of embossing a sheet processed by laminating 2 sheets by cutting has been described, but the sheet may have 2 or more sheets, and may have 3 sheets, for example. In addition, when 3 sheets of base paper are laminated, when the middle sheet is a rigid sheet and the outer side is a flexible sheet capable of capturing dust, a sheet having rigidity that does not break even if strongly rubbed, flexibility, good touch feeling, and easy removal of dirt can be obtained.
