Description

Technical Field

[0001] The present invention relates to a wet cleaning sheet capable of inhibiting the generation of mold on a surface to be cleaned after wiping and sweeping. Background Art

[0002] Conventionally, there are wet sheets (wet tissues) for wiping off body dirt, sweat, etc. Such wet sheets are available in laminated sheets and rolled sheets, and a plurality of wet sheets are stored in a predetermined bag or container.

[0003] Furthermore, recently, there is a need for wet sheets that do not use ethanol so that they can be used safely by users such as infants and young children who are sensitive to skin irritation. However, if ethanol is not used, there is a concern that mold will grow in the wet sheets in the bag or container before the sheets are used up.

[0004] Therefore, a wet sheet (wet tissue) that can prevent the growth of mold and the like even without using ethanol has been proposed (for example, see Patent Document 1).

[0007] Patent Document 1: Japanese Patent No. 6795889 Summary of the invention

[0008] However, to prevent mold growth in the bathroom, you can use anti-mold fumigants, but anti-mold fumigants cannot remove mold that has already occurred.

[0009] Therefore, in order to remove the mold that has already formed, a sprayer is generally used to apply a liquid medicine to the wall surface, ceiling, etc. and then sweep it off. However, the liquid medicine applied to the ceiling may drip, and this requires attention, so the mold removal sweeping is relatively cumbersome.

[0010] Therefore, the present inventors have conducted intensive research and developed a cleaning sheet that can wipe off dirt such as mold and provide an anti-mold effect to the surface to be cleaned after wiping and cleaning.

[0011] An object of the present invention is to provide a wet cleaning sheet capable of suppressing the growth of mold on a surface to be cleaned after wiping and sweeping.

[0014] The invention described in claim 3 of the present invention is characterized in that, in the cleaning wet sheet described in claim 1 of the present invention, the chemical solution is adjusted to be acidic.

[0015] The invention described in the fourth aspect of the present invention is characterized in that, in the cleaning wet sheet described in any one of the first to third aspects of the present invention, a plurality of convex embossings and concave embossings are respectively formed on the above-mentioned base paper sheet, the above-mentioned convex embossings are convex embossings on the first surface, and the above-mentioned concave embossings are convex embossings on the second surface.

[0016] The invention described in the first aspect of the present invention is characterized in that it is the wet cleaning sheet described in the fourth aspect of the present invention, and the wet cleaning sheet is a wet cleaning sheet for bathroom cleaning.

[0018] Figure 1 It is a perspective view showing a cleaning tool to which the wet cleaning sheet according to the present embodiment is attached.

[0019] Figure 2 1 is a plan view showing a wet cleaning sheet according to the present embodiment. DETAILED DESCRIPTION

[0020] Hereinafter, a wet cleaning sheet 100 as an embodiment of the present invention will be described with reference to the drawings. However, the technical scope of the present invention is not limited to the examples shown in the drawings, but is always determined based on the description of the scope of the claims.

[0021] It should be explained that, Figure 1 The front and rear, left and right, up and down, X direction, Y direction, and Z direction are defined and described. In the present specification, “to” is used to include the numerical values ​​described before and after it as the lower limit and the upper limit.

[0022] [1. Description of the structure]

[0023] First, the structure of the cleaning wet sheet 100 will be described.

[0024] [(1) Status during use]

[0025] like Figure 1As shown, the cleaning wet sheet 100 is, for example, a sheet that is replaceably mounted on a cleaning tool 200 and used for cleaning floors, walls, and ceilings, and is a sheet in which a chemical solution is impregnated in a base paper sheet. The cleaning tool 200 has a rectangular flat-plate head 201 and a handle 202 mounted on the upper surface of the head 201.

[0026] By attaching the cleaning wet sheet 100 to the head 201 of the cleaning tool 200 having the long rod-shaped handle 202 and using it, it is easy to wipe and clean not only the floor but also the high places of the wall surface and the ceiling.

[0027] It should be noted that the base paper sheet here refers to the state before the cleaning wet sheet 100 is impregnated with the chemical solution.

[0028] like Figure 2 As shown, the cleaning wet sheet 100 is formed in a rectangular shape, covers the bottom surface of the head 201 of the cleaning tool 200 to form a cleaning surface, is bent along the long side edge 201a of the head 201 of the cleaning tool 200 at a fold line S, and is clamped on the upper surface of the head 201 to be installed on the cleaning tool 200.

[0029] It should be noted that the long side edge portion 201 a refers to an edge portion along the long side direction of the head portion 201 , that is, it refers to two longer edge portions among the four edge portions of the rectangular head portion 201 .

[0030] [(2) Original paper]

[0031] The base paper sheet is a nonwoven fabric produced by bonding predetermined fibers together using a known technique such as hydroentanglement, hot air, air-laid, point bonding, spunbonding, and needle punching.

[0032] Specifically, as the base paper sheet, for example, a nonwoven fabric produced by mixing hydrophilic fibers and hydrophobic fibers and then bonding these fibers is used.

[0033] [a Hydrophilic fiber]

[0034] As the hydrophilic fiber, natural fibers such as cotton, pulp, and hemp, and regenerated fibers such as rayon and ketone ammonia fibers can be used. However, from the viewpoint of maintaining water retention, pulp, rayon, polypropylene spunbond fibers (PPSB), etc. are preferably used.

[0035] The blending ratio of the hydrophilic fibers in the fibers constituting the base paper sheet is preferably 35% by mass to 75% by mass.

[0036] [b water-repellent fiber]

[0037] As hydrophobic fibers, polyolefin fibers such as polyethylene (PE), polypropylene (PP), polyvinyl alcohol, polyester fibers such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), acrylic fibers, etc. can be cited, which can be used alone or in combination of two or more. As two or more composite fibers, core-sheath type with a relatively low melting point resin (low melting point resin) as a sheath and a relatively high melting point resin (high melting point resin) as a core, and side back type with low melting point resin and high melting point resin arranged in parallel in a specified direction can be cited.

[0038] The blending ratio of the hydrophobic fibers in the fibers constituting the base paper sheet is preferably 25% by mass to 65% by mass.

[0039] [cWeight per unit area]

[0040] From the viewpoint of achieving a balance between dirt retention and sheet softness, the basis weight of the base paper sheet is preferably 50 to 100 g / m 2 In addition, the weight per unit area refers to the basis weight measured according to JIS P8124:2011.

[0041] [(3) Liquid medicine]

[0042] As the chemical solution impregnated into the base paper sheet as described above, a chemical solution containing at least iodopropynyl butylcarbamate, polyaminopropyl biguanide, benzalkonium chloride, cetylpyridinium chloride, of liquid medicine.

[0043] Iodopropynyl butylcarbamate (IPBC) is a preservative that mainly exhibits an antiseptic effect on fungi. In the drug solution, the content of iodopropynyl butylcarbamate is preferably 0.005% by mass to 0.02% by mass. If it is within this range, the manufacturing cost is suppressed within an appropriate range and a good antifungal effect is exhibited.

[0044] Polyaminopropyl biguanide is a cationic preservative. The content of polyaminopropyl biguanide in the drug solution is preferably 0.05% by mass to 0.1% by mass. Within this range, the production cost can be kept within an appropriate range and a good antifungal effect can be exerted.

[0045] Benzalkonium chloride is a cationic preservative. The content of benzalkonium chloride in the drug solution is preferably 0.05% to 0.125% by mass. If it is less than 0.05% by mass, it is difficult to show the antiseptic effect, and if it is more than 0.125% by mass, skin irritation may increase.

[0046] Cetylpyridinium chloride It is a cationic surfactant with high antifungal effect. The content of is preferably 0.01 mass % to 0.03 mass %. If it is less than 0.01 mass %, the antiseptic effect is difficult to exhibit, and if it is more than 0.03 mass %, foaming may occur, which may hinder the production process.

[0047] The chemical solution is impregnated at 150% to 450% by mass, preferably 180% to 350% by mass, based on the mass of the base paper sheet when dried.

[0048] The chemical solution is impregnated in the dry base paper sheet and released from the cleaning surface when the cleaning wet sheet 100 is used.

[0049] [(4) Embossing]

[0050] like Figure 1 and Figure 2 As shown, the cleaning wet sheet 100 is provided with embossing 20. The embossing is a portion that compresses the sheet in the Z direction by making the sheet have projections and depressions, and utilizing the projections and depressions to scrape off dirt, thereby improving the ability to wipe off dirt on the surface to be cleaned.

[0051] For example Figure 2 As shown, the embossing 20 is formed into a so-called gourd shape that is short in one direction and narrow in width when viewed from above, and has a reduced diameter portion approximately in the center of the long axis direction. The shape of the embossing 20 is not limited to this, and may be, for example, various shapes such as polygons, or a shape obtained by combining various shapes. However, from the viewpoint of improving the scraping performance of dirt, such a gourd shape is preferred.

[0052] The embossing 20 can be formed by, for example, hot embossing at a temperature of 80°C to 200°C and an embossing pressure of 0.2 MPa to 1.0 MPa. When the embossing 20 is formed by hot embossing, a roller having at least an outer peripheral surface made of carbon steel, stainless steel, or a cured resin such as polypropylene or ABS (Acrylonitrile Butadiene Styrene) resin can be used as a convex embossing roller. Among them, from the viewpoint of durability and heat resistance, it is preferable to use a roller made of stainless steel.

[0053] When embossing is performed by heat embossing, it is preferably performed before the step of impregnating the cleaning wet sheet 100 with a chemical solution from the viewpoint of easily imparting a concavo-convex shape.

[0054] [a convex embossing, concave embossing]

[0055] As the embossing 20, there are formed a convex embossing 21 which is convex on the upper side in the Z direction (the first surface side of the wet cleaning sheet 100) and a concave embossing 22 which is convex on the lower side (the second surface side of the wet cleaning sheet 100) (that is, concave on the upper side in the Z direction). In each figure, the convex embossing 21 is indicated by a solid line, and the concave embossing 22 is indicated by a dotted line.

[0056] The convex embossing 21 is formed to be 5 mm to 10 mm in the long axis direction, preferably 6 mm to 8 mm. In addition, it is formed to be 2 mm to 5 mm in the short axis direction orthogonal to the long axis direction, preferably 3 mm to 4 mm, and is formed to be 0.5 mm to 2 mm in the Z direction (height from the middle part (described later)), preferably 0.7 mm to 1.5 mm. The concave embossing 22 is formed to be substantially the same shape as the convex embossing 21 when observed in cross section, and is formed to be convex to the lower side in the Z direction.

[0057] [b middle part]

[0058] An intermediate portion is formed between the embossings 20 formed on the wet cleaning sheet 100. The intermediate portion is a portion where the embossings 20 are not formed, and is therefore located lower than the convex embossings 21 and higher than the concave embossings 22 in the Z direction.

[0059] [cEmbossed pattern]

[0060] In the cleaning wet sheet 100 of this embodiment, for example Figure 2 As shown, the first direction ( Figure 2 The first embossed block 30 of a rhombus shape formed by a combination of convex embossing 21 and concave embossing 22 forms an embossed block row 31 continuously from the first side a to the second side b, and a plurality of embossed block rows 31 are continuously arranged from the third side c to the fourth side d. In adjacent first embossed block rows 31 and second embossed block rows 31, the first embossed block 30 in the first embossed block row 31 and the adjacent second embossed block 30 in the second embossed block row 31 are oriented in a second direction ( Figure 2 The 3rd side (in the Y direction) has an overlap and is arranged so that there is at least one convex embossing 21 and concave embossing 22 on a straight line extending perpendicularly from an arbitrary point on the 3rd side c to the 4th side d.

[0061] [d Non-embossed part]

[0062] like Figure 2 As shown, between adjacent embossed blocks 30, non-embossed portions 40 are provided which are not compressed in the Z direction compared to the portions of the wet cleaning sheet 100 where the embossing 20 is formed and have raised hairs.

[0063] The non-embossed portion 40 can be formed by designing a convex embossing roll for forming the embossing 20 so as to remove the shape of the non-embossed portion 40, or by compressing the embossing 20 slightly more than the compressed portion to such an extent that fuzz remains.

[0064] By providing 25% to 50% of the non-embossed portion 40 relative to the area of ​​the wet cleaning sheet 100, the occurrence of wiping streaks can be reduced, and the wet cleaning sheet 100 with excellent wiping properties can be obtained. It is most preferred that the non-embossed portion 40 be provided at 25% relative to the area of ​​the wet cleaning sheet 100.

[0065] It should be noted that when the cleaning wet sheet 100 is mounted on the cleaning tool 200 for wiping and sweeping, it is usually moved substantially perpendicularly to the X direction or the Y direction. Figure 2 As shown, when the non-embossed portion 40 is formed in a straight line, there is a concern that wiping streaks may be easily generated due to the angle of the wet cleaning sheet 100. Therefore, it is more preferable to arrange the embossed block 30 so that the non-embossed portion 40 is not formed in a straight line.

[0066] [2.Explanation of the effect]

[0067] The wet cleaning sheet 100 of the present embodiment is provided with embossed blocks 30 (embossed block array 31) each including a plurality of convex embossings 21 that are convex embossings on the first surface and a plurality of concave embossings 22 that are convex embossings on the second surface.

[0068] According to such a cleaning wet sheet 100, dirt on the surface to be cleaned can be scraped off by utilizing the unevenness of the embossing 20 (the convex embossing 21 and the concave embossing 22), and wiping cleaning for wiping off dirt can be appropriately performed.

[0069] In particular, the cleaning wet sheet 100 of the present embodiment is impregnated with iodopropynyl butylcarbamate, polyaminopropyl biguanide, benzalkonium chloride, cetylpyridinium chloride, The liquid medicine has antifungal properties, so that the liquid medicine can be applied to the surface to be cleaned after being wiped with the wet cleaning sheet 100, thereby providing an antifungal effect to the surface to be cleaned.

[0070] Thus, according to the wet cleaning sheet 100 of this embodiment, the anti-mold effect can be imparted to the surface to be cleaned after wiping and sweeping, so that, for example, mold dirt generated in the bathroom can be wiped off and the anti-mold effect can be imparted to the surface to be cleaned.

[0071] Moreover, if Figure 1As shown, if the cleaning wet sheet 100 is mounted on the head 201 of the cleaning tool 200 having the long rod-shaped handle 202 and used, it is possible to properly wipe and clean high places such as the ceiling of the bathroom, so that mold cleaning in the bathroom can be easily performed compared to cleaning by applying a liquid medicine with a sprayer.

[0072] Furthermore, according to the wet cleaning sheet 100 of the present embodiment, by disposing the embossing 20 as described above, the dirt wiping performance can be improved by utilizing the unevenness of the sheet, and the following effects can be obtained.

[0073] That is, generally, when the cleaning wet sheet 100 is mounted on the cleaning tool 200 having the head 201 and wiping and cleaning is performed, the cleaning wet sheet 100 is moved in the first direction ( Figure 2 X direction) or the second direction ( Figure 2 However, if the embossing patterns are arranged in series so as to be aligned along the first direction or the second direction, areas that have not been wiped off by the embossing patterns (so-called "wiping streaks") may occur on the cleaned surface. Even though liquid medicine remains in the sheet, users who see the wiping streaks may judge that the liquid medicine has been used up and dried, and the wet sheet may be discarded, which sometimes results in unnecessary use of too many wet sheets.

[0074] On the other hand, when a cleaning wet sheet 100 having the embossed pattern as described above is installed and arranged so that at least one convex embossing 21 exists on a straight line extending from an arbitrary point on the third side c to the fourth side d, at least in the second direction ( Figure 2 When wiping and sweeping is performed in the Y direction, the convex embossings 21 have overlapping edges, thereby reducing the generation of wiping streaks.

[0075] In addition, by providing a non-embossed portion 40 of 25% to 50% of the area of ​​the wet cleaning sheet 100 between each embossing block 30 instead of the embossing 20 on the entire surface of the wet cleaning sheet 100, when wiping and sweeping with the wet cleaning sheet 100, the convex embossing 21 protruding more than the non-embossed portion 40 is subjected to a greater pressure, thereby improving the release of the liquid and being able to further reduce the occurrence of wiping streaks.

[0076] In addition, since the convex embossing 21 is subjected to a greater pressure, the scraping performance of the convex embossing 21 is improved, and garbage is easily accumulated in the non-embossed portion 40, so the garbage collection performance can be improved. In addition, even if the scraping performance of the convex embossing 21 and the garbage collection performance of the wet cleaning sheet 100 are improved, the non-embossed portion 40 is not easy to contact the cleaned surface due to the convex embossing 21, so the increase in wiping resistance can be suppressed accordingly.

[0077] Furthermore, since the embossed blocks 30 are rhombus-shaped embossed blocks composed of embossing 20 such that the angle between the first direction and the long axis direction is 5° to 45°, preferably 15° to 35°, when a plurality of embossed block rows 31 arranged continuously from the first side a to the second side b are arranged continuously from the third side c to the fourth side d, the embossed blocks 30 are necessarily arranged to be offset with respect to the first direction of the wet cleaning sheet 100. In addition, when the user performs wiping and cleaning, a margin is generated in the angle at which the wet cleaning sheet 100 is moved.

[0078] Furthermore, since the embossing 20 is an elliptical shape having a constricted portion substantially in the center in the long-axis direction, the dirt scraping performance can be improved.

[0079] Example

[0080] Next, the results of evaluating examples of the present invention will be described. Hereinafter, the present invention will be specifically described by way of examples, but the present invention is not limited to these.

[0081] <Preparation of drug solution samples>

[0082] As a solution for mold removal, an acidic solution (pH 3.16) and an alkaline solution (pH 8.91) were prepared according to the components and their blends (mass %) shown in Table 1.

[0083] [Table 1]

[0084]

[0085] As the base paper sheet, a fiber blend of PET / pulp / PP / PP·PE=45 / 35 / 15 / 5 and a basis weight of 100 g / m 2 The nonwoven fabric has been implemented Figure 2 The embossed base paper sheet shown.

[0086] A sample of a wet cleaning sheet obtained by impregnating the base paper sheet with 200% of an acidic chemical solution and a sample of a wet cleaning sheet obtained by impregnating the base paper sheet with 200% of an alkaline chemical solution were prepared.

[0087] <Fungus resistance test method>

[0088] A reproduction test was conducted when the surface of an FRP board (fiber reinforced plastic board) frequently used in a system bathroom was wiped and cleaned with the cleaning wet sheet 100 .

[0089] Here, five FRP plates of 50 mm×50 mm were arranged side by side on the left and right, a sample of a wet sheet for cleaning was placed on the right end, and a weight of 150 g was placed on the sample.

[0090] Then, the sample of the cleaning wet sheet with a heavy object placed thereon was moved to the left end of the five FRP plates in about 2 seconds, and then moved from the left end to the right end in about 2 seconds.

[0091] In this way, the wet cleaning sheet sample placed on the FRP plate was reciprocated once to simulate wiping and cleaning. Specifically, the wet cleaning sheet sample was fixed to the bottom of a 300 ml beaker, and about 10 ml of water was put into the beaker to make 150 g, and it was reciprocated once. It should be noted that the FRP plate set in the center of the five FRP plates was used for the test.

[0092] Thus, two FRP plates were obtained, one after being wiped with the sample of the cleaning wet sheet impregnated with the acidic chemical solution and the other after being wiped with the sample of the cleaning wet sheet impregnated with the alkaline chemical solution.

[0093] In addition, the weight of 150 g is set as a reproduction when wiping and sweeping is performed using the cleaning tool 200 which is a floor brush.

[0094] One of the FRP plates wiped with each sample was wiped off and then naturally dried.

[0095] Thus, an acidic formula wiping and sweeping sample (sample A) and an alkaline formula wiping and sweeping sample (sample B) were obtained.

[0096] In addition, for the remaining one of the FRP plates after being wiped with each sample, 5 ml of distilled water was sprayed onto the cleaned surface using a sprayer, and then the plate was naturally dried.

[0097] Thus, a sample (sample C) in which the acidic formula was wiped and then treated with running water and a sample (sample D) in which the alkaline formula was wiped and then treated with running water were obtained.

[0098] It should be noted that 5 ml of distilled water is used as a shower to 5 cm from the surface to be cleaned. 2 This is set to reproduce the amount of water when spraying water for 0.5 seconds.

[0099] Next, the above four samples (A to D) were placed on an inorganic salt agar plate medium supplemented with glucose in a culture dish, and 0.1 mL of the mixed spore suspension was inoculated on the entire surface of the sample and the agar plate medium. The agar plate medium was cultured in a constant temperature chamber (29±1°C, relative humidity above 95%) for 4 weeks.

[0100] The mold developed in the petri dish was observed, and the development state of the mold was evaluated using the following 6 levels.

[0101] The antifungal test is based on JIS Z 2911, and the effect is confirmed when the difference is one level or more compared with the untreated sample.

[0102] 6-level evaluation

[0103] "0": No fungal growth was observed under the naked eye or microscope.

[0104] "1": The growth of mold was not confirmed with the naked eye, but was clearly confirmed under a microscope.

[0105] "2": Fungal growth was observed visually, and the area of ​​the growth was less than 25% of the total area of ​​the test specimen.

[0106] "3": Fungal growth was observed with the naked eye, and the area of ​​the growth was 25% or more and less than 50% of the total area of ​​the sample.

[0107] "4": The mycelium is well developed, and the area of ​​the developed part is more than 50% of the total area of ​​the specimen.

[0108] “5”: The mycelium is vigorously developed and covers the entire surface of the specimen.

[0109] <Test results>

[0110] Evaluations of four types of samples (A to D) and a blank sample are shown below.

[0111] Acidic formula wiping and sweeping sample (sample A): Rating "3"

[0112] Alkaline formula wiping and sweeping sample (sample B): Rating "1"

[0113] · Acidic formula · Flowing water treatment sample (Sample C): Rating "4"

[0114] · Alkaline formula· Running water treatment sample (sample D): Rating "4"

[0115] Untreated sample (blank): Rating "5"

[0116] From these results, it was found that the four samples (A to D) were provided with antifungal effects.

[0117] In particular, it is found that the sample B in which the simulated wiping and sweeping was performed using the sheet impregnated with the alkaline-formulated chemical solution has a high antifungal effect.

[0118] It is found that the sample A, which was subjected to simulated wiping and sweeping using a sheet impregnated with an acidic-formulated chemical solution, also exhibited a sufficient antifungal effect.

[0119] Furthermore, it was found that after wiping and cleaning with a wet cleaning sheet, if water was sprayed on the cleaned surface with a shower, the anti-mold effect was reduced.

[0120] According to the above results, both the cleaning wet sheet 100 impregnated with the alkaline-formulated chemical solution and the cleaning wet sheet 100 impregnated with the acidic-formulated chemical solution can provide an antifungal effect to the surface to be cleaned after wiping and cleaning.

[0121] In particular, the use of the cleaning wet sheet 100 impregnated with a chemical solution having an alkaline formulation (a chemical solution presenting alkaline properties) provides a high antifungal effect.

[0122] In addition, if it is Figure 2 The cleaning wet sheet 100 shown is provided with an embossed block 30 (embossed block row 31). Regardless of whether the liquid is alkaline or acidic, the dirt on the cleaned surface can be scraped off by utilizing the convex and concave embossing 20 (convex embossing 21, concave embossing 22), and the dirt can be wiped off appropriately.

[0123] Especially in the bathroom, when cleaning water stains, soap scum marks, and so-called "scale dirt", the cleaning wet sheet 100 impregnated with an acidic formula liquid has a high dirt removal rate and can perform cleaning well.

[0124] That is, if the cleaning wet sheet 100 is impregnated with an acidic liquid (acidic liquid), it can be used as a wet sheet for cleaning the bathroom to wipe off dirt well and can suppress the formation of mold on the cleaned surface after wiping and cleaning.

[0125] As described above, according to the wet cleaning sheet 100 of the present embodiment, dirt can be appropriately wiped off, and the generation of mold on the surface to be cleaned after wiping and cleaning can be suppressed.

[0126] In addition, if the cleaning wet sheet 100 is mounted on the head 201 of a cleaning tool 200 (floor brush) having a long rod-shaped handle 202 and used, it is possible to properly wipe and sweep high places such as the ceiling of the bathroom, thereby making it easier to clean mold in the bathroom compared to sweeping by applying a liquid with a sprayer or bringing a footstool into the bathroom for cleaning.

[0127] That is, if the cleaning wet sheet 100 of this embodiment is used in combination with a cleaning tool 200 such as a floor brush, it is possible to wipe and clean the floor and walls, as well as high places such as the ceiling where it is difficult to clean mold. This can suppress the formation of mold on the cleaned surface without using an anti-mold fumigant, making it easy to maintain the bathroom in a clean state.

[0128] It should be noted that in the above embodiment, the use of the wet cleaning sheet 100 to clean the bathroom is described as an example, but the present invention is not limited to this. The wet cleaning sheet 100 can also be used to clean water-using places such as washrooms and toilets. In addition, instead of using the cleaning tool 200, the wet cleaning sheet 100 held in the hand can be used for wiping and cleaning.

[0129] In addition, other specific detailed structures and the like may of course be changed appropriately.

[0130] Industrial Applicability

[0131] Since the present invention is constructed as described above, it can be used as a wet sheet for cleaning.
