Description

[Technical Field]

[0001] The present invention relates to kitchen towel roll products. [Background technology]

[0002] Kitchen towels are widely used for cleaning kitchen appliances such as microwave ovens and stoves, draining and wiping dishes, removing moisture from raw vegetables, meat, fish, and other ingredients, draining oil from fried foods, etc., and are required to have sufficient water and oil absorption capacities for these uses. For this reason, various bulky papermaking technologies have been proposed to increase the water and oil absorption capacities of kitchen towels.

[0003] Patent Document 1 describes a method for manufacturing a sheet having pulp as a main component, which is made up of one sheet or two or more sheets stacked together to form a set, and the basis weight of the set is 15 g / m 2 More than 50g / m 2 The following kitchen towels are disclosed: an oil absorption / basis weight of 4.5 to 7.5 oil-g / g (claim 1); a height difference of the surface irregularities of 100 to 600 μm when the length of the measurement field of view, avoiding embossing in mechanical processes other than the paper machine, is 1.0 to 1.4 mm (claim 3, paragraphs 0021 and 0022); and a surface depression area ratio of 2 to 12% measured under conditions of a scan area of ​​10 cm × 10 cm (claim 4, paragraph 0023). Patent Document 1 also discloses a kitchen towel manufacturing method in which a textured fabric is pressed against a wet paper web to create textured surfaces while dewatering, and then the wet paper web is dried (claim 6). Patent Document 1 provides a kitchen towel that uses pulp as the main component and has high oil absorption even with a low basis weight.

[0004] Patent Document 2 discloses a tissue papermaking device for producing high bulk tissue paper. The device has a press section that presses and textures a wet fibrous web, and the press section includes a texture belt having a texture layer, and the texture layer is nonwoven and has a web-carrying side with a surface that cooperates with the fibrous web, and the surface has depressions or raised portions that form a three-dimensional structure (Claim 1). According to Patent Document 2, a tissue papermaking device that produces high bulk tissue paper has a press section that presses and textures a wet fibrous web, and the press section includes a texture belt having a texture layer that cooperates with the fibrous web, and the surface has depressions or raised portions that form a three-dimensional structure (Claim 1). 3 / g or more 20cm 3 / g or less, and high-bulk tissue paper that can be produced at low energy costs using press technology is provided (paragraph 0013).

[0005] [Patent Document 1] International Publication No. WO2014 / 041681 [Patent Document 2] Special Publication No. 2011-506780 Summary of the Invention [Problem to be solved by the invention]

[0006] Kitchen towels are generally used in the form of kitchen roll towels wound into a roll. However, when bulky kitchen towels are wound into a roll, there is a problem that the roll tends to loosen. When loosely wound kitchen roll towels are packaged, poor sealing and scorching (holes caused by burning) occur, reducing the aesthetic appeal of the package and increasing the rate of defective products. If the kitchen towels are tightly rolled, the packaging will be good, but the kitchen towels will be crushed and their water absorbency will be reduced, and the benefits of bulky papermaking technology will not be obtained.

[0007] On the other hand, by increasing the basis weight of the kitchen towel excessively and tightly winding it, it is possible to achieve both aesthetic packaging and the absorbency of the kitchen towel, but this leads to other problems such as rising manufacturing costs and the paper quality of the kitchen towel becoming hard, reducing wiping properties.

[0008] Kitchen roll towels are packaged in a packaging resin film and sold commercially as kitchen roll towel products. Various packaging styles are known, among which caramel packaging is widely used because it improves the aesthetic appeal of kitchen roll towel products and allows more kitchen roll towel products to fit into a single cardboard shipping box without collapsing. However, caramel packaging presents another problem: if the kitchen towels are wrapped loosely, the aesthetic appeal of the packaging is reduced, and if they are wrapped tightly, the absorbency of the kitchen towels is reduced.

[0009] The object of the present invention is to provide a kitchen roll towel product in which a roll of 2-ply kitchen towels that combines high levels of water absorption and wiping properties and has a good feel when used is packaged at low cost and has excellent cosmetic properties. [Means for solving the problem]

[0010] As a result of extensive research to solve the above problems, the inventors discovered that a kitchen roll towel product that meets the objectives can be obtained by winding up a softer kitchen towel than conventional ones, with basis weight, water absorption, and specific volume each set within a predetermined range, into a roll at a predetermined roll density, and then caramel-wrapping it in a packaging resin film, which led to the completion of the present invention.

[0014] A kitchen roll towel product 1 of this embodiment will be described below with reference to the drawings. Figs. 1 and 2 show a kitchen roll towel product (hereinafter also simply referred to as "product") 1 and a kitchen roll towel (hereinafter also simply referred to as "roll") 2, respectively. Figs. 3 and 7 show how to determine the embossed area of ​​a kitchen towel 11x and how to measure the amount of water absorption, respectively. Figs. 4 and 5 show height profiles on the XY plane taken with a microscope. Fig. 6 shows the results of measurements of a 1 mm2 area. 2 Over 40mm 2 The method for determining the depth of the following embossing units is shown below. Figure 8 shows a part of the papermaking process for kitchen towel 11x. Figure 9 shows a linear embossed pattern. Figure 10 shows a non-embossed portion.

[0015] <Kitchen roll towel products> The kitchen roll towel product 1 of this embodiment is a two-ply laminate having an embossed pattern, and has a paper machine-derived uneven pattern imparted between the head box of the paper machine and the entrance of the Yankee dryer, and has a basis weight of 30 g / m 2 More than 54g / m 2 Below, water absorption is 200g / m 2 More than 600g / m 2 or less, and specific volume is 8cm 3 / g or more 20cm 3 / g or less, a sheet (or strip) of kitchen towel 11x, with a roll density of 0.04 g / cm 3 More than 0.15g / cm 3 The kitchen roll towels 2 are wound around a core 10 such as a paper tube or plastic tube as shown below, and the resulting kitchen roll towels 2 are aligned lengthwise and placed side by side in two pieces wrapped in a packaging film 20 to form a caramel-wrapped product. The packaging form for the kitchen roll towel product 1 is preferably caramel-wrapped, but is not limited to this and can be any of the packaging forms currently used for commercially available products. The number of kitchen roll towels 2 to be packaged is not limited to this embodiment and may be one, three, or more. The embossed pattern on the kitchen towel 11x includes a paper-machine-derived uneven pattern (embossed pattern) automatically applied between the head box of the paper machine and the entrance to the Yankee dryer, as well as other embossed patterns, such as those described below.

[0016] One caramel package is not limited to this embodiment and may contain one roll 2 or three or more rolls 2. When multiple rolls 2 are packaged, two or three rolls 2 are preferred from the viewpoint of aesthetic appearance of the package. By packaging the rolls 2 in caramel, sealing defects and scorch (holes caused by burning) are less likely to occur, and the aesthetic appearance of the package is significantly improved. Furthermore, the caramel packaging provides excellent strength and ease of opening.

[0017] According to this embodiment, by adjusting three specific properties of the two-ply laminate having an embossed pattern derived from a paper machine, namely, basis weight, water absorption, and specific volume, within respective predetermined ranges, a kitchen towel 11x can be obtained that has high levels of water absorbency, oil absorbency, wiping ability, etc., while also having a soft paper quality not previously available. A roll 2 obtained by winding such kitchen towel 11x at a predetermined roll density is less likely to loosen, and even when packaged, there are no sealing defects or scorch (holes caused by burning), resulting in a highly decorative package.Furthermore, even without tightly winding, it is possible to achieve both decorative packaging and water absorbency of the kitchen towel at low manufacturing costs, and a high level of decorative packaging can be maintained even when packaged in caramel. Each component of the kitchen roll towel product 1 will be specifically described below.

[0018] <Kitchen towel> As described above, the kitchen towel 11x of this embodiment is a two-ply laminate with a papermachine-derived uneven pattern applied between the head box of the papermachine and the entrance of the Yankee dryer. In the kitchen towel 11x, an adhesive layer may be provided between the plies to prevent ply peeling. The adhesive layer may be provided over the entire surface between the plies or only a portion of the surface. Any known adhesive that does not affect the water absorption or texture of the kitchen towel 11x can be used without particular limitation, such as glue. The kitchen towel 11x may or may not have a print. In the following description, the surface of the kitchen towel sheet 11x facing the outside of the roll 2 shown in FIG. 2 is referred to as the front surface 11a, and the surface facing the core 10 of the roll 2 is referred to as the back surface 11b.

[0019] (Basic weight) The kitchen towel 11x of this embodiment has a basis weight of 30 g / m 2 More than 54g / m 2 or less, preferably 34 g / m 2 More than 50g / m 2 or less, and more preferably 38 g / m 2 More than 46g / m 2 The basis weight is 30 g / m or less.2 If the basis weight is less than 54 g / m, the feel of the kitchen towel 11x when in use tends to deteriorate. 2 If the weight exceeds this, the kitchen towel 11x will become hard and will not conform to the shape of the object, which will tend to reduce wiping performance. Basis weight is measured in accordance with JIS P 8124.

[0020] (Water absorption amount) Kitchen towel 11x has a water absorption capacity of 200g / m 2 More than 600g / m 2 or less, preferably 300 g / m 2 More than 500g / m 2 or less, more preferably 350 g / m 2 More than 450g / m 2 Here, in the units of water absorption, "g" indicates the weight of water absorbed by the kitchen towel 11x, and "m 2 " indicates the area of ​​the kitchen towel 11x that has absorbed water. When the kitchen towel 11x is cut into sheets of a size that is easy to handle, the water absorption capacity is 200 g / m 2 If it is less than this, the ability to wipe off water tends to decrease, and the water absorption capacity will exceed 600g / m 2 If the amount of water absorbed exceeds this limit, the sheet of that size cannot be used effectively, and the sheet must be discarded even though it still has water absorption capacity.

[0021] (Method for measuring water absorption) The water absorption amount is measured, for example, in the following order (a) to (c). (a) Take 11x kitchen towels stacked in two layers and cut them using a square template with each piece measuring 7.6 cm (3 inches) to prepare a rectangular test piece with each side measuring 7.6 cm. Measure the mass of the test piece before water absorption using an electronic balance. Place the test piece in the holder shown in Figure 7 (a jig that fixes three points of the test piece, made of metal that does not absorb water). (b) Distilled water is poured into a commercially available tray to a depth of 2 cm, and the test specimen set in the holder is immersed in the distilled water for 2 minutes. After immersion for 2 minutes, the test specimen and holder are removed from the distilled water, and a band 210 is attached to one corner 200d of the test specimen 200 as shown in Figure 7. The band 210 is made by cutting a kitchen towel 11x identical to the sample to be measured into a size of 2 mm wide x 15 mm long, and attaching it to a section 6 mm from the corner 200d toward the center of the test specimen. (c) The holder 220 and the test piece 200 are hung from a rod placed in an empty water tank with the corner 200a opposite the corner 200d facing up, the lid of the water tank is closed, and the test piece 200 is left for 10 minutes. Thereafter, the holder 220 and the test piece 200 are taken out of the water tank, the belt 210 and the holder 220 are removed, and the mass of the test piece 200 is measured using an electronic balance. From the change in mass of the test piece 200 before and after immersion in distilled water, the mass of the test piece 1m is calculated. 2 Absorption of distilled water per g of paper (g of water / m 2 ) is calculated. Measurements are carried out five times for each sample, and the average value is used. This measurement is performed according to JIS P 8111 at a temperature of 23±1°C and humidity of 50±2%. The distilled water is kept at 23±1°C.

[0022] (specific volume) The kitchen towel 11x of this embodiment has a specific volume of 8 cm 3 / g or more 20cm 3 / g or less, preferably 10 cm 3 / g or more 18cm 3 / g or less, more preferably 12cm 3 / g or more 16cm 3 / g or less. Specific volume is 8cm 3 If the specific volume is less than 20 cm3, the water absorption rate tends to decrease. 3 If the density exceeds 1 / g, the strength will decrease and the paper will tend to tear easily. The specific volume is the value obtained by dividing the paper thickness of a kitchen towel (2-ply laminate) 11x by the basis weight, and is expressed as the volume cm per unit g. 3 The basis weight, water absorption, specific volume, etc. can be adjusted to a predetermined range by appropriately adjusting, for example, the beating conditions of the raw material, the calendering conditions of the base paper web, the creping conditions, the embossing conditions, etc.

[0023] In a preferred embodiment, the kitchen towel 11x has the following physical properties and / or configuration in addition to the physical properties described above.

[0024] (DMDT and DCDT) DMDT (Dry Machine Direction Tensile Strength, hereinafter also referred to as "dry longitudinal strength") is the tensile strength of the kitchen towel 11x in the longitudinal direction when dry based on JIS P 8113, and from the viewpoint of wiping performance, etc., it is, for example, in the range of 4 N / 25 mm to 16 N / 25 mm, 5 N / 25 mm to 13 N / 25 mm, or 6 N / 25 mm to 10 N / 25 mm. If the DMDT is in the above range, the soft feel of the kitchen towel 11x is fully exhibited and wiping performance is improved. DCDT (Dry Cross Direction Tensile Strength, hereinafter also referred to as "dry cross strength") is the tensile strength of the kitchen towel 11x in the cross direction when dry based on JIS P 8113, and from the viewpoint of wiping performance, etc., is, for example, in the range of 3 N / 25 mm to 13 N / 25 mm, 4 N / 25 mm to 13 N / 25 mm, or 5 N / 25 mm to 10 N / 25 mm. If the DCDT is in the above range, the soft feel of the kitchen towel 11x is fully exhibited, and wiping performance is improved. If the DMDT is less than 4 N / 25 mm and / or the DCDT is less than 3 N / 25 mm, the kitchen towel 11x tends to tear easily when absorbing water, resulting in reduced wiping performance. If the DMDT is greater than 16 N / 25 mm and / or the DCDT is greater than 13 N / 25 mm, the kitchen towel 11x tends to become denser, absorbency is reduced, and the paper becomes more rigid, resulting in reduced wiping performance. The DMDT / DCDT ratio is, for example, in the range of 0.8 to 2.0, 0.9 to 1.8, or 1.0 to 1.6. By maintaining the DMDT / DCDT ratio within the aforementioned range, the kitchen towel 11x has a soft and comfortable feel. If the DMDT / DCDT ratio is less than 0.8, the sheet tends to tear easily when torn along the perforations. If the DMDT / DCDT ratio is greater than 2.0, the feel of use tends to vary depending on the wiping direction. DMDT and DCDT can be adjusted by, for example, the jet / wire ratio, the machine speed, the raw material discharge angle, and the like.

[0025] (perforation) In a preferred embodiment, the kitchen towel 11x further has a plurality of perforations (not shown) extending in the width direction thereof to cut the kitchen towel 11x in the width direction, the perforations being provided at predetermined intervals in the longitudinal direction, and the area of ​​one kitchen towel piece surrounded by two adjacent perforations in the longitudinal direction (hereinafter also referred to as the "sheet area") is 0.02 m 2 More than 0.10m 2 Range below 0.03m 2 Over 0.08m 2 The following range or 0.04m 2 More than 0.06m 2 The range is as follows. This kitchen towel piece can also be said to be a sheet cut at two adjacent perforations in the longitudinal direction. The sheet area must not be set alone, but must be set in conjunction with the properties of the kitchen towel 11x, particularly the basis weight, water absorption capacity, and specific volume. In this embodiment, by setting the optimal water absorption capacity, oil absorption capacity, etc. for a sheet area with good wiping properties, a highly convenient kitchen towel piece can be obtained. When the area of ​​the kitchen towel piece is 0.02 m 2 If the area is less than 0.10 m, it will be difficult to wipe the object, and one piece of kitchen towel will not be enough to wipe the object. 2 If the capacity exceeds this, the kitchen towel strip will often be discarded while there is still room for water or oil absorption, and one kitchen towel strip will not tend to be used effectively.

[0026] (ply peel strength) The ply peel strength of the kitchen towel 11x is, for example, in the range of 0.01 N / 75 mm to 1.5 N / 75 mm, 0.03 N / 75 mm to 1.3 N / 75 mm, or 0.05 N / 75 mm to 1.0 N / 75 mm. Setting the ply peel strength within the above ranges makes it easier to adjust the roll density within the range specified in this embodiment. If the ply peel strength is less than 0.01 N / 75 mm, the plies tend to peel off from each other, making wiping difficult. If the ply peel strength is more than 1.5 N / 75 mm, the water absorption capacity of the kitchen towel 11x tends to decrease.

[0027] Ply peel strength was measured in accordance with the tensile test method of JIS P 8113 using a tensile testing machine (STB-1225S, manufactured by A&D Co., Ltd.) under the standard conditions specified in JIS P 8111. First, a test piece measuring 75 mm in the width direction and 200 mm in the machine direction was taken from a kitchen towel 11x sample. Next, the ply was peeled 35 mm in the machine direction. One side of the peeled ply was clamped 15 mm in the machine direction between upper clamps (75 mm wide). The other ply was also clamped 15 mm in the machine direction between lower clamps (75 mm wide). The clamp pitch (spacing) was 20 mm. Next, the specimen was pulled (peeled) at a tensile speed of 100 mm / min, and strength data was collected. Strength data is obtained every 20 μm, and the data from 40 mm to 150 mm (measurement length 110 mm) after the start of measurement is averaged to obtain the peel strength (N / 75 mm). However, if the perforation is included in the distance from 40 mm to 150 mm after the start of measurement, the distance after the start of measurement can be shortened from 40 mm to, for example, 90 mm (measurement length 50 mm) as long as it does not include the perforation.

[0028] (embossed pattern) The kitchen towel 11x may have an embossed pattern different from the papermaking machine-derived uneven pattern. Such an embossed pattern can be easily formed, for example, by processing using an embossing roll having convex portions on its peripheral surface (hereinafter also referred to as "embossing"). The area ratio of the convex portions on the embossing roll [(total area of ​​the convex portions / total surface area of ​​the embossing roll) × 100] is, for example, in the range of 4% to 40%, 6% to 30%, or 9% to 18%. By setting the area ratio of the convex portions on the embossing roll within the above-mentioned range, it is easy to adjust the ply peel strength within a preferred range. If the area ratio of the convex portions is less than 4%, the plies tend to peel off from each other, making wiping difficult. If it exceeds 40%, water absorbency tends to decrease. Furthermore, the kitchen towel 11x of this embodiment may be formed by laminating two plies after embossing a single-ply sheet. When laminating two plies, it is preferable to apply a ply-bonding glue to the two plies for adhesion. By bonding the two plies together in this way, the plies are more strongly bonded together, making the kitchen towel 11x less likely to tear even when wet. It also helps the embossed shape to be more easily maintained, maintaining a good appearance, absorbency, and wiping ability.

[0029] The ply on the front surface 11a of the kitchen towel 11x may have, for example, a dot-shaped embossed pattern or a line-shaped embossed pattern. When a dot-shaped or line-shaped embossed pattern is applied to the front surface 11a, glue can be applied to the embossed portions of the embossed pattern for adhesion, making the ply of the kitchen towel 11x less likely to peel off and suppressing large fluctuations in water absorption. Furthermore, the ply on the back surface 11b of the kitchen towel 11x is not particularly limited as to whether it has an embossed pattern, as long as it has a different concavo-convex pattern derived from the papermaking process. It may have nested embossing or pin-to-pin embossing, or may not be embossed; however, nested embossing or no embossing is preferred, and no embossing is more preferred.

[0030] In a preferred embodiment, the embossed pattern is a linear embossed pattern from the viewpoint of ease of setting the numerical value of the ply peel strength. The linear embossed pattern is not particularly limited as long as it includes two types of figures, namely, a substantially circular figure with another pattern therein, and a figure that is substantially line-symmetrical in the vertical and horizontal directions as a whole and includes a combination of multiple curves and figures, as shown in Fig. 9. In a more preferred embodiment, the substantially circular figure has two substantially circular figures.

[0031] In a linear embossing pattern, the total length of all embossments that are 0.1 mm or more and 4 mm or less in thickness and 5 mm or more in length (total length of all embossments having the above dimensions) is, for example, 50 cm / 100 cm. 2 More than 550cm / 100cm 2 Range below: 80cm / 100cm 2 More than 410cm / 100cm 2 The following range or 110cm / 100cm 2 More than 300cm / 100cm 2 The range is as follows: By setting the total length within the above range, for example, it becomes easier to adjust the ply peel strength within an appropriate range.

[0032] The total length mentioned above is measured as the sum of the lengths of all embossments that are 0.1 mm to 4 mm in thickness and 5 mm or longer within a rectangle E that includes one embossed pattern as shown in Figure 9, and is 100 cm. 2The total length per square E is defined as the total length per square. The size of one side of this rectangle E can be changed as appropriate depending on the size of the embossed pattern. If a rectangle containing all embossed patterns contains an embossed pattern adjacent to an embossed pattern contained within the rectangle, the length of the adjacent embossed pattern is also measured and included in the total length. If the size of one side of rectangle E cannot be clearly determined based on the embossed pattern, the size of rectangle E is set to 10 cm x 10 cm, and the total length of the embossed length contained within this rectangle E is measured. By keeping the total length within the above range, in a kitchen towel 11x with high water absorption such as that of this embodiment, the ply is less likely to peel off and wiping properties are improved. The total length is determined by actual measurement using the method described above. Note that measurement may also be performed using a general microscope.

[0033] In the embossing pattern, the embossing depth is, for example, in the range of 0.06 mm to 1.1 mm, 0.10 mm to 0.80 mm, or 0.20 mm to 0.55 mm. If the embossing depth is less than 0.06 mm, the plies tend to peel off easily in a kitchen towel 11x with high water absorption capacity such as that of this embodiment. If the embossing depth exceeds 1.1 mm, the specific volume of the kitchen towel 11x increases, and the water absorption capacity tends to be difficult to improve despite the bulkiness.

[0034] In the embossed pattern mentioned above, the size is 1 mm 2 Over 40mm 2 An embossment with the following area is considered a single embossment: 100cm2 of unit area in the embossing pattern 2 The number of embossed units per unit area is not particularly limited, but may be, for example, in the range of 20 to 1800, 50 to 1000, or 80 to 500. If the number of embossed units is less than 20, the plies tend to peel off easily in the case of a kitchen towel 11x with good absorbency such as that of this embodiment. If the number of embossed units exceeds 1800, the kitchen towel 11x tends to be crushed, resulting in a decrease in absorbency. The shape of the embossed units may be circular, oval, rectangular, square, floral, or other shapes without particular limitations.

[0035] In addition, in the embossed pattern mentioned above, the area is 1 mm 2 Over 40mm 2 The depth of each embossing unit is, for example, in the range of 0.10 mm to 0.80 mm, 0.25 mm to 0.67 mm, or 0.35 mm to 0.55 mm. If the depth of the embossing unit is less than 0.10 mm, the water absorption capacity of kitchen towel 11x tends to decrease and the feel during use tends to be poor, while if it exceeds 0.80 mm, kitchen towel 11x tends to become bulky, the roll density tends to decrease, and the decorativeness of the package tends to decrease.

[0036] The area and depth of the embossment are measured using a microscope. The microscope used is a Keyence One-Shot 3D Measuring Macroscope VR-3100. The microscope image observation, measurement, and image analysis software used is the VR-H1A. The measurement conditions are a magnification of 12x and a field of view of 24mm x 18mm. The measurement magnification and field of view may be changed as appropriate depending on the desired size of the embossment.

[0037] As shown in Figure 3, the area of ​​the embossment is calculated by measuring the length a of the longest part of the periphery fr of the embossment and the length b of the longest part in the direction perpendicular to length a, and then calculating the product of these (a x b). Figure 4 shows a height profile on the XY plane taken by a microscope, with the height of the sheet surface represented by shading. The roughly elliptical areas in Figure 4 that are different in shading from the surrounding area represent individual embosses, and the length a of the longest part of one of these embossments can be visually identified. Of these, the area of ​​the embossment with an area of ​​1 mm 2 Over 40mm 2 The following embossing units are 100cm 2 Count the number of pieces per piece.

[0038] The number of embossments is measured across the entire width of the sheet, from the entire area between two adjacent perforations in the longitudinal direction, at any 100cm 2Select a part of the surface and measure it visually. 2 If you cannot select this area, measure the number of embossments on the measurable areas, excluding areas that cannot be measured due to knurling (edge ​​embossing), etc., and measure the number of embossments on 100cm 2 The number of embossments per unit is calculated.

[0039] Next, the area is 1 mm 2 Over 40mm 2 The embossing depth is measured for the following embossing units. The embossing depth is determined by measuring the height difference of the embossing using the microscope mentioned above. First, draw line segment AB as shown in Figure 4 to obtain the height profile shown in Figure 5. Note that line segment AB should be drawn so that it crosses the embossment. The height profile is a (measured) cross-sectional curve S that represents the unevenness of the actual sheet sample surface, but it also contains noise (steep peaks caused by fiber clumps on the sheet surface, fiber whiskers, and fiber-free areas), and such noise peaks must be removed when calculating the height difference of the unevenness.

[0040] Then, as shown in Figure 6, a "contour curve" W is calculated from the cross-sectional curve S of the height profile. The difference between the average value of the bottoms P1 and P2 and the apex between the bottoms P1 and P2 is calculated and defined as the embossment depth D1. Similarly, the difference between the average value of the bottoms P2 and P3 and the apex between the bottoms P2 and P3 is calculated and defined as the embossment depth D2. Similarly, D3 is measured. Note that D1, D2, and D3 are measured at consecutive locations, as shown in Figure 6. This measurement is performed at 10 locations on the kitchen towel 11x, and the average of the data from a total of 30 locations is defined as the embossment depth. Note that if the distance between the embosses (the distance between P1 and P2) is 1 cm or more, measurements are not performed at consecutive locations. Instead, the difference between the average value of the bottoms P1 and P2 and the apex between the bottoms P1 and P2 is calculated and defined as the embossment depth D1. Alternatively, D1 can be measured at 30 locations and the average value defined as the embossment depth.

[0041] The "profile curve" is a curve obtained by removing surface roughness components with wavelengths shorter than λc: 800 μm (λc is the "filter that defines the boundary between the roughness component and the waviness component" described in JIS B 0601, "3.1.1.2") from the cross-sectional curve using a low-pass filter. Note that if λc is set to be greater than the distance between adjacent embossments P1 and P2, or P2 and P3 (this is called the emboss pitch), there is a risk that the peaks will be recognized as noise, so λc is set to be less than the emboss pitch. For example, if the emboss pitch is 800 μm or less, λc is set to, for example, 250 μm.

[0042] When measuring the embossment, the measurement surface is the front side, and when selecting the embossment, the measurement is made at a point that is 10% of the length of the roll 2 from the outer end of the roll 2 (the point where you start using the kitchen towel 11x). For example, if the roll length is 30 m, the measurement is made at a point that is 30 m x 10% = 3 m from the end. Note that if the 10% portion of the roll length corresponds to a perforation, the measurement is made on the outer side of the perforation.

[0043] (non-embossed part) In another preferred embodiment, the root mean square height Sq of the surface roughness of the portion of the kitchen towel 11x not provided with the embossed pattern (hereinafter also referred to as the "non-embossed portion") is, for example, in the range of 35 μm or more, 50 μm to 150 μm, 60 μm to 120 μm, or 70 μm to 90 μm. By setting the root mean square height Sq of the surface roughness of the non-embossed portion to 35 μm or more, for example, it becomes easy to adjust the water absorbency of the kitchen towel 11x to the appropriate range specified in this embodiment. If the root mean square height Sq of the surface roughness is less than 35 μm, the water absorbency tends to decrease. Furthermore, while there is no particular upper limit for the root mean square height Sq of the surface roughness, if the value is too high, the product may become bulky.

[0044] The root mean square height Sq of the surface roughness of the non-embossed portion is measured, for example, using a microscope. As with the embossing depth described above, the microscope used is a Keyence One-Shot 3D Measuring Macroscope VR-3100, and the microscope image observation, measurement, and image analysis software is the VR-H1A. The measurement conditions are a magnification of 38x and a field of view of 8mm x 6mm. The measurement magnification and field of view may be changed as appropriate depending on the desired size of the non-embossed portion.

[0045] For the image shown in Figure 10, filters are set in the same way as for the embossing depth described above. Specifically, by setting an S-filter (low-pass filter), components with a scale smaller than the cutoff wavelength are removed from the image, and by setting an L-filter (high-pass filter), components with a scale larger than the cutoff wavelength are removed. Here, the S-filter is set to 500 μm, and the L-filter is set to 8 mm. By selecting the S-filter and L-filter, the root-mean-square height Sq is calculated automatically.

[0046] For the non-embossed portion, remove three laps of kitchen towel 11x from roll 2 and use the fourth lap of kitchen towel 11x to measure the two-ply sheet. Also, if there are perforations, avoid any of these when measuring. Measure at two locations across the width of roll 2, then rotate roll 2 three times by 90 degrees in the machine direction of kitchen towel 11x, and measure in the same way as above at each position (for a total of four measurement locations in the machine direction). The average of these eight locations (2 x 4) is the root mean square height Sq.

[0047] (roll length and paper thickness) The roll length of the kitchen towel 11x is not particularly limited, but is typically in the range of 20 m to 50 m, 25 m to 45 m, or 30 m to 40 m, depending on factors such as the frequency of replacement of the roll 2, ease of carrying and storing the product 1, etc. The thickness (paper thickness) of the kitchen towel 11x is also not particularly limited, but is typically in the range of 1.6 mm / 10 plies to 4.7 mm / 10 plies, depending on factors such as ease of adjusting the basis weight and water absorption, and strength. The paper thickness is measured using a thickness gauge (PEACOCK (registered trademark) dial thickness gauge manufactured by Ozaki Seisakusho Co., Ltd.). The measurement is performed with a load of 3.7 kPa and a probe diameter of 30 mm. A sample is placed between the probe and the measuring table, and the gauge is read when the probe is lowered at a rate of 1 mm per second or less. Five sets of two-ply kitchen towels 11x are stacked to form 10 plies, and the measurement is performed. The measurement is repeated 10 times and the results are averaged.

[0048] (WMDT and WCDT) The wet machine direction tensile strength (WMDT) of kitchen towel 11x, based on the former JIS S 3104, is, from the viewpoint of wiping performance, for example, in the range of 1.0 N / 25 mm to 7.0 N / 25 mm, 2.0 N / 25 mm to 6.0 N / 25 mm, or 2.5 N / 25 mm to 5.0 N / 25 mm. If the WMDT is within the above range, the towel will not tear and will be soft and easy to wipe. The wet cross direction tensile strength (WCDT) of the kitchen towel 11x, based on the old JIS S 3104, is, from the viewpoint of wiping performance, for example, in the range of 0.7 N / 25 mm to 7.0 N / 25 mm, 4.0 N / 25 mm to 13.0 N / 25 mm, or 5.0 N / 25 mm to 10.0 N / 25 mm. If the WCDT is within the above range, the kitchen towel 11x will not tear and will be soft and easy to wipe. If the WMDT is less than 1.0 N / 25 mm and / or the WCDT is less than 0.7 N / 25 mm, the kitchen towel 11x will be prone to tearing when absorbing water, and wiping performance will tend to be reduced. If the WMDT exceeds 7.0 N / 25 mm and / or the WCDT exceeds 7.0 N / 25 mm, the density of the kitchen towel 11x increases, and the wiping properties tend to decrease as the water absorbency decreases, or the towel tends to become hard and the wiping properties tend to decrease.

[0049] (sheet length) The sheet length of the paper towel 11x in the width direction (CD direction) of the roll 2 is, for example, in the range of 180 mm to 350 mm, in the range of 200 mm to 340 mm, or in the range of 250 mm to 300 mm. By setting the CD length of the paper towel 11x within the above-mentioned range, the roll 2 can be easily removed. Furthermore, the length of the paper towel 11x in the MD direction (pitch) perpendicular to the CD direction is, for example, in the range of 160 mm to 330 mm, in the range of 180 mm to 305 mm, or in the range of 200 mm to 280 mm. By setting the MD length of the paper towel 11x within the above-mentioned range, the roll diameter will be in an appropriate range.

[0050] (Material) Kitchen towel 11x is primarily composed of wood pulp and may contain, as necessary, one or more of recycled paper pulp, non-wood pulp, deinked pulp, etc., within the range that does not impair the quality of kitchen towel 11x. Kitchen towel 11x may also contain one or more of various additives.

[0051] Examples of wood pulp include NBKP (softwood kraft pulp) and LBKP (hardwood kraft pulp). NBKP can be any kraft pulp made from softwoods such as radiata pine, slash pine, southern pine, lodgepole pine, spruce, and Douglas fir. LBKP can be any kraft pulp made from hardwoods, but kraft pulp made from Eucalyptus genus (Myrtaceae), such as Eucalyptus grandis and Eucalyptus globulus, is preferred. Note that unbleached softwood pulp (NUKP) can be used instead of NBKP, and LUKP can be used instead of LBKP. A preferred embodiment of the kitchen towel 11x contains NBKP (softwood kraft pulp) and LBKP (hardwood kraft pulp). In this case, the ratio of NBKP to LBKP used is, for example, 25% by mass to 70% by mass to 30% by mass to 75% by mass, 35% by mass to 60% by mass to 40% by mass to 65% by mass, or 40% by mass to 55% by mass to 45% by mass to 60% by mass. Furthermore, by using a ratio of NBKP to LBKP in the range of 10% by mass to 100% by mass to 0% by mass to 90% by mass, a kitchen towel 11x that satisfies the basis weight, water absorption, and specific volume specified in this embodiment can be easily obtained.

[0052] Examples of recycled paper pulp include pulp made from liquid beverage cartons (such as milk cartons and liquor cartons). Examples of non-wood pulp include synthetic fibers made from synthetic resins such as nylon, vinylon, polyester, acrylic, polyethylene, polypropylene, and polystyrene. Examples of deinked pulp include pulp made from recycled newspaper and magazine paper. When deinked pulp contains fluorescent dyes, the content of deinked pulp containing fluorescent dyes should be 20% by mass or less of the total pulp used. Examples of additives include softeners including debonder softeners, bulking agents, dyes, dispersants, dry strength agents, wet strength agents, drainage aids, pitch control agents, and absorbency improvers.

[0053] <Kitchen roll towel> As shown in Figure 2, roll (kitchen roll towel) 2 is formed by winding kitchen towel 11x around core 10. There are no particular restrictions on the outer diameter D1 of core 10 of roll 2, but from the standpoint of facilitating adjustment of the winding density of roll 2 and ease of handling of roll 2 during production, it is, for example, in the range of 35 mm to 45 mm, or 37 mm to 42 mm. The main characteristics of roll 2 are described below.

[0054] (Core outer diameter) The core 10 is located at the center of the roll 2 and has a substantially circular cross section around which the paper towels 11x are wound. The roll 2 may have a paper tube inserted therein or may have a hollow portion. The core outer diameter is the outer diameter of the aforementioned core portion (paper tube, hollow portion, etc.). The core outer diameter is, for example, in the range of 30 mm to 60 mm, 34 mm to 55 mm, or 37 mm to 50 mm. According to this embodiment, a single product 1 can be wound with an amount of paper towels 11x that will not deteriorate during its use. Furthermore, the winding diameter of the roll 2 is not larger than necessary. The roll width of the roll 2 is, for example, in the range of 180 mm to 350 mm, 210 mm to 325 mm, or 240 mm to 300 mm. The roll mass of the roll 2 is, for example, in the range of 160 g to 550 g, 230 g to 450 g, or 270 g to 380 g. The roll mass is the mass per 280 mm of roll width, not including the core (paper tube) 10. If the roll width is not 280 mm, it is converted to the mass per 280 mm by proportional calculation.

[0055] (roll density) The roll density of roll 2 is 0.04 g / cm 3 More than 0.15g / cm 3 The following range, preferably 0.06 g / cm 3 More than 0.12g / cm 3 The following range is more preferably 0.07 g / cm 3 More than 0.09g / cm 3The roll density range is as follows. It is necessary to set the roll density according to the basis weight, water absorption, and specific volume of the kitchen towel 11x, rather than setting the roll density range independently. 3 If the roll density is less than 0.15 g / cm, the top and / or bottom of the product 1 cannot be folded neatly when packaging the caramel, resulting in unbonded areas and scorching, which tends to impair the cosmetic appearance. 3 If the roll diameter exceeds this value, the unevenness of the kitchen towel 11x tends to be crushed and the amount of water absorption tends to decrease when the roll diameter is constant.

[0056] Roll density is expressed as {{cross-sectional area of ​​the roll outer diameter (winding diameter DR)} - (cross-sectional area of ​​the core outer diameter DI)} x roll width (converted per 280 mm). For example, if the roll mass per 280 mm of roll width is 327 g, the winding diameter DR is 122 mm, and the core outer diameter is 39 mm, then roll density = 327 g ÷ [{3.14 × (122 mm ÷ 2 ÷ 10)² - 3.14 × (39 mm ÷ 2 ÷ 10)²} × (280 mm ÷ 10)] = 0.11 g / cm 3 If the roll 2 does not have a core, the diameter of the central hole is replaced with the core outer diameter DI.

[0057] (reel diameter) The diameter of the roll 2 per roll is, for example, in the range of 113 mm to 200 mm, 135 mm to 180 mm, or 140 mm to 160 mm. If the diameter is less than 113 mm, it tends to be difficult to achieve a good balance between the roll density and the water absorption capacity of the kitchen towel 11x. If the diameter exceeds 200 mm, the roll density and, therefore, the decorativeness of the packaging tend to decrease.

[0058] <Packaging film> The product 1 is obtained by caramel-wrapping one or more rolls 2 in a packaging film 20. For example, a resin film having heat-sealing properties is used as the packaging film 20. The packaging film 20 has heat-sealing properties, which allows packaging without using, for example, a hot-melt adhesive, and therefore improves the aesthetic appearance of the resulting product 1. The packaging film 20 may be single-layered or multi-layered. The material of the packaging film 20 is preferably a thermoplastic resin. Thermoplastic resins have heat-sealing properties and are suitable for recycling. Specific examples of thermoplastic resins include polyolefin resins such as polyethylene and polypropylene, polyester resins such as PET, polyamides (trade name nylon, etc.), polycarbonate, polystyrene, polyvinyl chloride, etc. Among these, polyethylene film is preferred.

[0059] The thickness of the packaging film 20 is, for example, in the range of 15 μm to 40 μm, 20 μm to 35 μm, or 25 μm to 30 μm. If the thickness is less than 15 μm, scorching may occur during heat sealing, reducing the aesthetic appeal and causing the packaging film 20 to tear. If the thickness exceeds 40 μm, the ease of opening the product 1 may be reduced. The packaging film 20 may or may not have perforations for opening the product 1.

[0060] <Method of manufacturing kitchen towel sheets and kitchen towel rolls> The kitchen towel sheet 11x and roll 2 can be manufactured, for example, in the following order: (1) papermaking and creping, (2) embossing, and (3) roll winding. The manufacturing process preferably uses through-air drying technology. In this process, a textured pattern derived from the papermaking process (fabric), different from the embossing pattern described above, is applied to the kitchen towel 11x during the papermaking and creping processes. This textured pattern further increases the water absorption capacity of the kitchen towel 11x. Note that "originating from the papermaking process" refers to the texture being applied between the headbox of the papermaking machine and the entrance of the Yankee dryer during the papermaking process of the kitchen towel 11x. The textured pattern is formed by drying the sheet together with the fabric in the through-air dryer section. More specifically, the textured pattern can be applied in the belt press section 30, located between the dewatering roll 31 and the Yankee dryer 32, as part of the papermaking process shown in Figure 8. In the belt press section 30, the wet paper 34 and the uneven belt 33 (the uneven belt 33 loops through the belt press section 30 and the Yankee dryer 32) are pressed together to give the wet paper a pattern of unevenness.

[0061] The unevenness pattern can be changed as needed by changing the fabric pattern (fine pattern, coarse pattern). Changing the unevenness pattern changes the specific volume (paper thickness), but it is preferable to select a pattern that ensures that the specific volume (paper thickness) of the base paper falls within the numerical ranges described below. It is also preferable to select a pattern that ensures that the specific volume of the kitchen towel 11x and the root mean square height Sq of the surface roughness of the non-embossed portion fall within the respective numerical ranges described above.

[0062] One or more of the kitchen roll towels 2 thus obtained are arranged side by side in the width direction with their longitudinal directions aligned, and then caramel-wrapped in a wrapping film 20 according to a known method as shown in FIG.

[0063] Although the present invention has been described above using embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope described in the above embodiments and examples. It will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. Furthermore, it is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention. [Example]

[0064] The present embodiment will be described in more detail below with reference to examples and comparative examples.

[0065] (Examples 1 to 17 and Comparative Examples 1 to 8) The raw pulp used was NBKP and LBKP in the proportions (mass%) shown in Tables 1 to 3, and the kitchen roll towel products of Examples 1 to 25 and Comparative Examples 1 to 12 were manufactured through the following processes: (1) papermaking and creping, (2) embossing, (3) roll winding, and (4) caramel wrapping. Parameters were measured and sensory evaluations were conducted for all of the kitchen towel roll products of the above Examples and Comparative Examples. The results are shown in Tables 1 to 3. The kitchen towels of Examples 1 to 25 and Comparative Examples 1 to 8 had uneven patterns derived from the papermaking machine.

[0066] The sensory evaluation was carried out by 20 monitors who selected "good" or "bad" for each evaluation item. The evaluation criteria were as follows: ◎, ○, and △ were considered to be acceptable. ◎: When 18 to 20 people answered "Good" ○: When 14 to 17 people answered "Good" △: When 10 to 13 people answered "Good" ×: When 6 to 9 people answered "Good" ××: When there are no "good" people or when there are 1 to 5 people

[0067] Each evaluation item will be explained below. <Water absorption per sheet> The monitors evaluated the amount of water remaining after using one sheet. <Can you use the sheet without waste?> The monitors used one sheet and evaluated whether they felt it was a waste to throw it away. <Cosmetic> The occurrence of scorch and unbonded areas was visually evaluated. <Resistant to tearing of packaging film> The resistance of the packaging film to tearing when the product was displayed or carried by hand was evaluated. <Openability> The ease of opening the packaging film by tearing it with fingers or by making a hole in it was evaluated. <Wipeability> The ease of wiping was evaluated by the monitors when they used the product. <Tactile sensation when in use> The monitors evaluated the quality of the feel when using the product. The results are shown in Tables 1 to 3.

[0068] [Table 1]

[0069] [Table 2]

[0070] [Table 3]

[0071] From Tables 1 to 3, it can be seen that by combining and satisfying the various configurations of this embodiment, a kitchen roll towel product can be obtained that receives a passing rating of ⊚ in most of the evaluation items, including "absorbency per sheet," "whether the sheet can be used without waste," "cosmetic appearance," "resistance to tearing of the film," "ease of opening," "ease of wiping," and "feel when used." Although some of the evaluation items are passing with a "△" rating, the majority of the evaluation items are passing with a "◎" rating. [Explanation of symbols]
