Description Body cleaning sheet Technical field

The present invention relates to a wet body wiping sheet. The wiping sheet of the present invention is used after being heated to a predetermined temperature. The present invention also relates to a hot wiping tool for wiping a surface to be wiped using the wiping sheet heated to a predetermined temperature. Further, the present invention relates to a thermal wiping method using the thermal wiping tool. Background art

BACKGROUND ART A body wiping sheet impregnated with an aqueous liquid is known. When wiping the body with such a wiping sheet, if the amount of the aqueous liquid released from the sheet is large, the aqueous liquid remains on the body surface and the body temperature is increased by the heat of vaporization generated when the liquid evaporates. Is deprived and becomes a cold stimulus. This cold stimulus can cause the elderly and infants who have wiped their bodies to feel sick, especially in the cold winter months. Therefore, when using the cleaning sheet, the cleaning sheet is heated with a microwave oven or with a special heating device. However, even when the wiping sheet is warmed, the amount of liquid discharged therefrom is large, and eventually, the body temperature is deprived by the heat of vaporization, resulting in a cold stimulus. In addition, if the body is washed using a heated wiping sheet, the temperature of the sheet will decrease over time due to the lack of a function to keep the sheet warm. The temperature drops until it reaches a cold stimulus. In particular, when the wiping area is wide and it takes a long time to clean the entire body of an adult, the temperature of the sheet at the end of wiping is remarkably lowered. Separately from the wiping sheet, Japanese Patent Application Laid-Open Nos. 9-252924 and 9-252689 describe steamed towels containing a water-absorbing polymer. Such steamed towels are used by immersing them in boiling water or pre-moistened water and heating them in a microwave oven. However, these steamed towels are used to stimulate motility stimulation of blood vessels in a part of the body in the first place, and are not intended to be used by releasing a liquid. Accordingly, the present invention provides a body wiping sheet which is prevented from giving a cold stimulus due to vaporization of an impregnated liquid or a decrease in temperature when wiping the body by heating to a predetermined temperature. With the goal. Another object of the present invention is to provide a hot wiping tool and a hot wiping method that can perform a wiping operation while maintaining a high temperature for a long time.

Hereinafter, the present invention will be described with reference to the drawings based on preferred embodiments. I will tell. FIG. 1 is a perspective view of an embodiment of a body wiping sheet (hereinafter, also referred to as a wiping sheet) of the present invention, and FIG. 2 is a sectional view taken along line II-11 in FIG. ing. As shown in FIGS. 1 and 2, the wiping sheet 1 of the present embodiment has a rectangular shape, and includes an inner layer 2 and two surface layers 3, 3 disposed on both surfaces of the inner layer 2. It is composed of a laminated sheet having a layer structure. The surface layer 3 has a larger dimension than the inner layer 2 and extends outward from the periphery of the inner layer 2. Both the inner layer 2 and the surface layer 3 are composed of a fiber sheet. The cleaning sheet 1 is a wet sheet impregnated with an aqueous cleaning agent for cleaning the body. Then wipe the sheet 1, in 2 0 0 0 g_ / 4 5 cm 2 of the luggage weight under released amount of the aqueous detergent 0. 0 4~0. 8 gZ 5 0 0 cm 2, preferably 0.1 00.7 g ノ 500 cm ² , more preferably 0.2 00.6 gZ500 cm ² . The present inventors have conducted various studies on the cold stimulus (so-called cool sensation) when wiping the body using a wet sheet impregnated with an aqueous cleaning agent. if the amount of the agent is 0. 8 g Z 5 0 0 cm 2 or less was observed knowledge to be able to suppress the cold stimulation due to vaporization of the aqueous detergent remaining on the body table surface. Therefore, even when the body of an elderly person or an infant is cleaned in a cold winter season, it is possible to prevent a cold stimulus from being given, and to prevent a physical disorder or the like. On the other hand, if the release amount is less than 0.0450 cm ² , a sufficient amount of the cleaning agent is not released, and the intended cleaning effect cannot be obtained. The reason for defining the unit of the amount of cleaning agent released based on 500 cm ² is that this area is almost equivalent to the area obtained by wiping an adult's arm 5 times. , 20 cmX 5 cm = 100 cm ² ). Also, the reason why the load at the time of release of the aqueous cleaning agent was set to 2000 g / 45 cm ² is that the area of the sheet for wiping the body is usually about 45 cm ² (actual hand force). The size of such a sheet is about 9 cm x 5 cm = 45 cm ² ). Force is about 2000 g. The specific method of measuring the release amount of the aqueous cleaning agent is as follows.

① Fix a sponge (PH-20 (SF felt, manufactured by Priston Co., Ltd.)) cut to 9 cm x 5 cm (X height: 2 cm) on the lower surface of a 2000 g rectangular parallelepiped weight. . The purpose of using this sponge is to make sure that the surface to be wiped (Ino'ak 'Corporation's “highly functional foam (1) TT1-1401)” described later) and the sheet always contact with a fixed area. is there.

② Cut the sheet to 9 cm x 15 cm and impregnate it with a certain amount of detergent.

(3) Wind the sheet so as to cover the sponge (the size of the sponge and the sheet in contact with each other is 9 cm x 5 cm).

として Use a high-performance form (1) TT—410 1 manufactured by INOATSU CORPORATION as the surface to be cleaned. A distance of 20 cm in length on the surface to be wiped is wiped five times (two and a half reciprocations) with a sheet around which a weight and a sponge are wrapped (wiping area is 100 cm ² X 5 times = 5 times). 0 cm ² ), and the amount of detergent release is calculated from the weight change before and after that. The reason why the high-performance foam (1) TT-4101 made by Inoatsu Corporation was adopted as the surface to be cleaned was that this form was used as the surface to be cleaned, This is because there was a correlation between the amount of cleaning agent released and the case where the arm was used as the surface to be cleaned. In order to control the release amount of the aqueous detergent within the above range, for example, it is effective to control the material of the sheet impregnated with the aqueous detergent. The sheet constituting the surface layer 3 is controlled by controlling the material of the sheet, for example, by changing the mixing ratio of a hydrophilic fiber and a non-hydrophilic fiber (for example, a core-sheath composite fiber composed of a combination of polyethylene and polypropylene). Can be varied in degree of hydrophilicity. Specifically, hydrophilic When a large amount of conductive fiber is mixed, the surface layer 3 easily holds the aqueous detergent, and the aqueous detergent is easily released by pressure, so that the release amount increases. Conversely, lowering the mixing ratio of the hydrophilic fibers makes it difficult for the surface layer 3 to hold the aqueous detergent, and increases the amount of the aqueous detergent retained in the inner layer 2. Also, the aqueous detergent is less likely to be released. Therefore, the amount released is small. On the other hand, in order to control the impregnation amount of the aqueous cleaning agent, the water absorption of the wiping sheet 1 may be controlled. For this purpose, the sheet constituting the inner layer 2 in the wiping sheet 1 preferably contains a water-absorbing polymer. Specifically, the inner layer 2 is preferably made of a fiber sheet containing particles of a water-absorbing polymer and a fiber material. By controlling the content of the water-absorbing polymer, the amount of the aqueous detergent impregnated and, consequently, the amount of release can be controlled. Furthermore, since the water-absorbing polymer absorbs the water in the aqueous cleaning agent, the heat capacity of the wiping sheet 1 as a whole increases, and the temperature of the wiping sheet 1 decreases in a short time when heated to a predetermined temperature. Can be prevented. This also prevents a cold stimulus from being applied. As described above, in the present invention, by including the water-absorbing polymer in the wiping sheet, (1) the release amount of the aqueous cleaning agent is controlled and the cold stimulus is suppressed, and (2) the cleaning stimulus is suppressed. There are two effects that the heat retention of the wipe sheet 1 is enhanced and the cold stimulus is suppressed. In order to effectively suppress cold stimulation by increasing the heat retention of the wiping sheet 1, the amount of the water-absorbing polymer contained in the wiping sheet 1, the amount of the aqueous detergent impregnated therein, and both The weight ratio is important. For the water-absorbent polymer and water-based cleaning agent, heat the cleaning sheet 1 to 60 ° C, and then maintain the temperature at 30 or higher after storing for 3 minutes in an environment of 23 and 65% RH. Possible amount included Is preferred. The reason for setting the storage time to 3 minutes is that the wiping time by one wiping sheet 1 is about 3 minutes in relation to the total release amount of the aqueous cleaning solution. The weight ratio of the water-absorbing polymer to the total weight of the wiping sheet 1 (the weight in the state in which the aqueous cleaning agent is impregnated) varies depending on the type of the water-absorbing polymer, but is from 0.0002 to 0.15. It is particularly preferably 0.04 to 0.11. The ratio of the weight of the aqueous cleaning agent impregnated to the weight of the wiping sheet 1 before the aqueous cleaning agent is impregnated is preferably 2 to 15, particularly preferably 4 to 10. Further, the weight ratio of the water-absorbing polymer to the aqueous detergent (the former or the latter) is preferably from 0.002 to 0.15, particularly preferably from 0.007 to 0.11. Inner layer 2 is in the shape of a strip. The strip-shaped inner layer 2 has a ratio of the length to the width of 1 to 100, particularly about 5 to 40. The width of the inner layer 2 is preferably 2 to 3 Omm, particularly 5 to 3 Omm, particularly preferably 10 to 3 Omm, from the viewpoint of the balance between the retention of the aqueous detergent and the sustained release. The length of the inner layer 2 is shorter than the length of the surface layers 3, and the surface layers 3, 3 extend from the front and rear edges of the inner layer 2. A plurality of inner layers 2 are used, and the inner layers 2 are arranged in one direction at predetermined intervals. The spacing is about 1 to 30 mm, especially about 2 to 20 mm, and especially about 3 to 11 mm, so that the surface layers 3 and 3 can be easily joined together and the area of the inner layer 2 is sufficient. It is preferable from the viewpoint of securing. The peripheral edge of each inner layer 2 is surrounded and continuously sealed by joining the two surface layers 3, 3 together. This prevents the swollen water-absorbing polymer from falling off the wiping sheet 1. From the viewpoint of preventing the falling-off, the sealing area of the two surface layers 3 is 3 to 95% of the area of the wiping sheet 1, particularly 5 to 80%, particularly 10 to 65%. Preferably, there is. The surface layers 3 are joined to each other by, for example, heat fusion using heat sealing or adhesion using an adhesive. Also, if necessary, The inner layer 2 and the surface layer 3 may be partially joined by embossing the sheet. The wiping sheet 1 has on its surface a plurality of linear recesses 4 extending in one direction and reaching the periphery of the wiping sheet. The longitudinal direction of each of the ridges 4 coincides with the longitudinal direction of the wet sheet 1. Each concave ridge 4 extends in the same direction as the longitudinal direction of the inner layer 2. The concave ridge portion 4 is located at the position of a joint portion 5 formed by directly joining the two surface layers 3, 3 except for the inner layer 2 in the laminated sheet, specifically, two surface layers 3, 3. Each inner layer 2 is continuously surrounded by a joint 5 formed by direct joining of the two surface layers 3,3. As a result, the concave stripes 4 are formed between the adjacent inner layers 2 and 2 and the concave stripes 4 are also formed on the peripheral edge of the cleaning sheet. The concave ridges 4 formed between the adjacent inner layers 2, 2 have both ends reaching the periphery of the wiping sheet 1. The formation of the concave ridges 4 improves the operability of wiping and the ability to prevent dripping. 'The concave ridge portion 4 is formed by a step between a three-layer portion composed of the inner layer 2 and the two surface layers 3 in the laminated sheet and a two-layer portion composed of the two surface layers 3. Therefore, the depth of the concave ridge portion 4 can be appropriately increased or decreased by the thickness of the inner layer 2. In particular, as will be described later, when the inner layer 2 contains a water-absorbing polymer, the thickness of the inner layer 2 can be extremely large due to the water-absorbing polymer swollen by the absorption of the aqueous detergent, and as a result, The depth can easily be increased. As described above, the inner layer 2 is continuously surrounded by the joint 5 formed by the direct joining of the two surface layers 3,3. That is, each inner layer 2 is independently and independently held in a sleeve-like space formed by the two surface layers 3, 3. As a result, the cleaning sheet 1 Even if it is used to wipe the body, the inner layer 2 is less likely to break or break. In addition, since a sufficient amount of the aqueous cleaning agent can be impregnated and held, the wiping sheet 1 can be prevented from cooling down quickly, and further, the sustained-release property is improved, and a proper wet feeling is maintained. Instead of holding the inner layer 2 in the space, the inner layer 2 and the surface layer 3 are bonded by heat embossing or the like so that even if a force is applied to the inner layer 2, the inner layer 2 is not broken. It may be possible to do so. However, in this case, if the water-absorbing polymer is contained in the inner layer 2, the water-absorbing polymer leaks from the hot embossed portion to the outside, or the water-absorbing polymer is fixed at the hot embossed portion and the absorption is inhibited. There is a disadvantage of causing Therefore, it is preferable that the inner layer 2 is not bonded to the surface layer 3 and is kept free in the space formed by the surface layer 3 as in the present embodiment. From the viewpoint of more effectively preventing the inner layer 2 from tearing and stably wiping, a laminated sheet before the aqueous detergent is impregnated (a sheet composed of the inner layer 2 and the surface layer 3). The breaking strength of the inner layer 2 in a state where 800% by weight of water is impregnated in the laminated sheet with respect to the dry weight of the laminated sheet is preferably 400 cN / 20 mm or more, more preferably 500 c N / 20 mm or more. It is particularly preferable that the value of the breaking strength measured in the longitudinal direction of the inner layer 2, that is, the same direction as the extending direction of the concave ridge portion 4, is equal to or more than the above value. The breaking strength is measured by the following method. The inner layer 2 is taken out of the impregnated cleaning sheet 1 and a test piece having a width of 2 Omm and a length of 8 Omm is cut out from the inner layer 2. Attach the test piece to the tensile tester with a distance of 50 mm between the chucks. The test piece is pulled at a speed of 300 mm / min, and the maximum load until it breaks is determined. The value is defined as the breaking strength. As described above, the inner layer 2 is preferably made of a fiber sheet containing particles of a water-absorbing polymer and a fiber material. Inner layer 2 is typically composed of non-woven fabric or paper. 20 times or more of its own weight as a water-absorbing polymer Those capable of absorbing and retaining the above liquid and gelling are preferred. Any shape, spherical, massive, grape-like, powdery or fibrous

Specific examples include polyacrylic acid and its salts, and polyacrylic acid graft polymers, such as starch-crosslinking lipoxyl methylated cellulose, polymers or copolymers of acrylic acid or alkali metal acrylates, and the like. be able to.

Examples include hydrophilic synthetic fibers, and synthetic fibers such as polyethylene fibers, polypropylene fibers, and polyester fibers that have been subjected to a hydrophilic treatment with a surfactant. One or more fiber materials can be used. In particular, it is preferable that the inner layer 2 contains a heat-fusible fiber so that the breaking strength of the inner layer 2 is not less than the above-mentioned value. In this case, the blending amount of the heat-fusible fiber in the fiber composition of the inner layer 2 is 20 to 70% by weight, particularly 20 to 50% by weight, particularly 20 to 40% by weight, and the balance is hydrophilic. It is preferable to be made of conductive fibers from the viewpoint of the balance between the improvement in the strength of the inner layer 2 and the improvement in the impregnation property of the aqueous detergent. Examples of the heat-fusible fibers include polyolefin resins such as polyethylene and polypropylene, polyester resins such as polyethylene terephthalate, acrylic resins such as polyacrylic acid and polymethacrylic acid, and vinyl resins such as polyvinyl chloride. Fibers made of resin, polyamide resin and the like are used. Further, among the above-mentioned various raw materials, a conjugate fiber (core-sheath type conjugate fiber or a side-by-side type conjugate fiber) composed of a combination of two kinds of resins can be used. In particular, the low melting point resin and the high melting point resin It is preferable to use a heat-fusible conjugate fiber in which the point resin forms at least a part of the fiber surface. Examples of low-melting resin / high-melting resin combinations include high-density polyethylene polypropylene, low-density polyethylene polypropylene, polypropylene / ethylene / butene-1-1 crystalline copolymer, high-density polyethylene / polyethylene terephthalate, and nylon-6-nonylone. 66, low melting point polyester polyethylene terephthalate, polypropylene polyethylene terephthalate and the like. The form of the heat-fusible conjugate fiber is parallel type, core-sheath type, eccentric sheath-core type, multilayer of three or more layers, hollow parallel type, middle-sheath core type, irregular-shaped sheath-core type, sea-island type, etc. It is sufficient that the resin has a structure in which at least a part of the fiber surface is formed. Preferred among the heat-fusible conjugate fibers are low melting points such as high-density polyethylene, linear low-density polyethylene, ethylene, butene-1 crystalline copolymer, and copolymerized polyester of polyethylene terephthalate and polyethylene isophthalate. A parallel, sheath-core, or eccentric sheath-core composite fiber in which any one of thermoplastic resins selected from polyester is used as a low-melting resin, and polypropylene or polyethylene terephthalate is used as a high-melting resin. In particular, from the viewpoint of thermal adhesion, it is preferable to use a composite fiber of low-density polyethylene and polyethylene terephthalate or a composite fiber of low-density polyethylene and polypropylene. The fiber sheet constituting the inner layer 2 can be produced from the above-described materials as a raw material by a wet papermaking method, or various nonwoven fabric production methods such as an airlaid method, an air-through method, and a spunlace method. Further, as the fiber sheet, an absorbent sheet described in Japanese Patent Application Laid-Open No. Hei 8-24639 or International Publication WO09 / 693923 can be used. The weight ratio between the particles of the water-absorbing polymer and the fiber material in the fiber sheet constituting the inner layer 2 (the former / the latter) is 0.05 to 1.0, in particular, 0 :! A value of 5 is preferable from the viewpoint of the heat retention performance of the water-absorbing polymer. For the same reason, the basis weight of the water-absorbing polymer itself is preferably from 5 to 100 gm ² , particularly preferably from 10 to 80 g / m ² . The basis weight of the fiber sheet constituting the inner layer 2, depending on the basis weight of the whole wiping sheet 1, 3 0~ 5 0 0 g / m , especially 6 0: is preferably 1 5 0 g Zm ² . The surface layer 3 is a rectangle whose length is slightly larger than the length of the inner layer 2 and whose width is several times to tens of times the width of the inner layer 2. The surface layer 3 has the outer shape of the wiping sheet 1. The surface layer 3 is preferably made of a fiber sheet containing hydrophilic fibers such as hydrophilic cellulose fibers. The surface layer 3 is typically composed of a non-woven fabric. Examples of the hydrophilic cellulose fiber include regenerated cellulose fiber such as rayon and cuvula, wood pulp such as softwood kraft pulp and hardwood kraft pulp, and natural cellulose fiber such as cotton pulp and pulp pulp. The fiber sheet constituting the surface layer 3 may be composed only of hydrophilic cellulose fibers, or may contain another fiber material. As the other fiber material, for example, the same material as the heat-fusible fiber contained in the inner layer 2 can be used. When the fiber sheet constituting the surface layer 3 contains fibers other than the hydrophilic cellulose fiber, the other fibers are contained in an amount of 2 to 70% by weight, particularly, based on the weight of the surface layer 3 (dry basis). It is preferably contained in an amount of 30 to 60% by weight. The hydrophilic cellulose fiber is preferably contained in an amount of 30 to 98% by weight, particularly preferably 40 to 70% by weight, based on the weight (dry basis) of the surface layer 3. The fiber sheet constituting the surface layer 3 can be manufactured by various nonwoven fabric manufacturing methods such as a wet papermaking method, a spunless method and an airlaid method. The basis weight of the fiber sheet constituting the surface layer 3 depends on the basis weight of the entire wiping sheet 1, but is 20 to each; L 0 g Zm ² , particularly 30 to 70 g Zm ² Is preferred. Incidentally, the two surface layers 3 may be the same or different types. The laminated sheet in which the inner layer 2 and the surface layer 3 are integrally laminated (the laminated sheet before being impregnated with the aqueous detergent) has a basis weight of 40 to 500 gZm ² , particularly 70 to 400 gZm ² . g / m ² , especially 120 to 290 gZm ² , is preferred from the viewpoint of the feel when holding the sheet in hand and the ease of wiping.

Further, the impregnation rate of the aqueous detergent with respect to the weight of the sheet before the impregnation with the aqueous detergent may be 200 to 150% by weight, particularly 400 to 100% by weight. preferable. Next, the aqueous cleaning agent will be described. The aqueous cleaning agent contains water as a medium and contains cleaning components. Various surfactants can be used as the cleaning component. As the surfactant, any of anionic surfactants, nonionic surfactants, cationic surfactants and amphoteric surfactants can be used.

It is also preferable to use a food additive-based surfactant. The reason is as follows. If the cleaning sheet 1 is heated in a microwave oven as described below, the aqueous cleaning agent may remain inside, thereby indirectly contacting the food with the aqueous cleaning agent. May be From the viewpoint of safety in that case, the surfactant contained in the aqueous detergent is preferably a food additive. The surfactant is preferably contained in the aqueous detergent in an amount of 0.01 to 30% by weight, particularly 0.05 to 2% by weight, from the viewpoint of exhibiting a sufficient cleaning effect. It is preferable that the aqueous detergent contains a water-soluble solvent having a boiling point of 100 ° C. or higher, particularly an alcohol. As a result, rapid evaporation of the aqueous cleaning agent released from the wiping sheet 1 is suppressed, and cold irritating is further suppressed. As the water-soluble solvent having a boiling point of 100 ° C. or more, alcohols such as propylene glycol, glycerin, polyethylene glycol and dipropylene glycol can be used. The water-soluble solvent is also preferably a food additive-based solvent. The reason for this is the same as the reason why it is preferable to use a food additive-based surfactant. A particularly preferred water-soluble solvent is dipropylene glycol. The use of dipropylene glycol can also prevent stickiness. The water-soluble solvent contains 2 to 70% by weight, particularly 3 to 50% by weight, particularly 5 to 30% by weight in the aqueous detergent, which further suppresses the cold stimulus, and It is preferable from the viewpoint of the heat retaining property of the wipe sheet 1 and the moisture retaining property to the skin.

Water as a medium in the aqueous detergent is preferably contained in the aqueous detergent in an amount of 30 to 99.9% by weight, more preferably 50 to 95% by weight, and still more preferably 60 to 95% by weight. . The wiping sheet 1 of the present embodiment is used after being heated to a predetermined temperature by various heating means. It is convenient to use a microwave as a heating means. The heating temperature is from 35 to 85 ^, preferably from 40 to 80, and particularly preferably from 50 to 75 ° C, from the viewpoint of handleability and sufficient suppression of cold stimulation. Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, only the differences from the first embodiment will be described, and as for the points that are not particularly described, the detailed description of the first embodiment will be applied as appropriate. 3 and 4, the same members as those in FIGS. 1 and 2 are denoted by the same reference numerals. Similar to the first embodiment, the wiping sheet 1 of the present embodiment has a three-layer structure of an inner layer 2 containing a water-absorbing polymer and surface layers 3 and 3 disposed on both sides of the inner layer 2. Consists of a laminated sheet. As shown in FIGS. 3 and 4, the wiping sheet 1 of the present embodiment has a rectangular shape, and includes an inner layer 2 and two surface layers 3, 3 arranged on both surfaces of the inner layer 2. It is composed of a laminated sheet having a layer structure. The surface layer 3 has a larger dimension than the inner layer 2 and extends outward from the periphery of the inner layer 2. Both the inner layer 2 and the surface layer 3 are composed of a fiber sheet. As shown in FIG. 3, the wiping sheet 1 is embossed in a rhombic lattice pattern, whereby the inner layer 2 and the surface layer 3 are partially integrated. Also, the absorbent polymer contained in the inner layer 2 is prevented from falling off. By partially integrating the inner layer 2 and the surface layer 3, the swelling of the water-absorbing resin that has absorbed water in the aqueous detergent is not hindered. ing. Also, by partially integrating, a large number of irregularities are formed on the surface of the wiping sheet. The unevenness further enhances the wiping effect. From the viewpoint of further improving the wiping effect, the total area of the protrusions is preferably 30 to 97%, particularly 45 to 90%, based on the apparent area of the wiping sheet 1. Better. In the present embodiment, since the rhombic lattice pattern is embossed, the convex portions have a rhombic shape. As shown in FIG. 4, the surface layer 3 extends outward from the periphery of the inner layer 2. The peripheral edge of the inner layer 2 is continuously sealed by being surrounded by the two extended surface layers 3. Thereby, even if the water-absorbing polymer contained in the inner layer 2 swells due to absorption, the water-absorbing polymer is prevented from falling off from the wiping sheet 1. From the viewpoint of preventing the falling-off, the area sealed by the two surface layers 3, 3 is preferably 2 to 95%, particularly 10 to 70% of the area of the wiping sheet 1. The present invention is not limited to the above embodiment. For example, in the embodiment shown in FIG. 1 and FIG. 2, at a position inside the peripheral edge of the laminated sheet, there are a plurality of joints 5 extending in one direction and having both ends reaching the peripheral edge. Instead of this, as shown in FIG. 5, a plurality of openings 6 are formed in the inner layer 2 made of one sheet, and each layer except the inner layer 2 is joined at the position of the opening 6. Thus, a plurality of joints 5 may be formed. Further, the wiping sheet of the above embodiment has a three-layer structure of the inner layer and the two surface layers, but instead, another layer may be provided between the inner layer and the surface layer or outside the surface layer. They may be arranged to form a multilayer structure of four or more layers. In this case, the bonding portion 5 is formed by bonding the layers except the inner layer. As a modification of the embodiment shown in FIGS. 3 and 4, the wiping sheet 1 may have a two-layer structure including the inner layer 2 and one surface layer 3. Also, water absorption A single-layer structure may be used as long as the polymer can be retained and there is no risk of falling off. Further, in the above-described embodiment, a fiber sheet is used as the inner layer 2 and the surface layer 3, but a foam sheet such as a sponge may be used instead. Further, in the above embodiment, the inner layer is continuously surrounded by the joint formed by joining the two surface layers. However, the inner layer is connected to the inner layer as long as the water-absorbing polymer can be prevented from falling off. It may be discontinuously surrounded by parts. Next, a thermal wiping tool and a thermal wiping method of the present invention will be described based on preferred embodiments with reference to the drawings. FIG. 6 shows a perspective view of one embodiment of the thermal wiping tool of the present invention. The thermal wiping tool 10 shown in FIG. 6 includes a wiping sheet 1 and a housing 11. A plurality of cleaning sheets 1 are stored in the storage body 11 in a stacked manner. The storage body 11 has a rectangular parallelepiped storage part 31 having a space in which the wiping sheet 1 can be stored and having an open top. A hinge 32 is provided at the open end of the back surface of the storage section 31. A lid 33 that closes the opening of the storage section 31 is attached to the hinge 32. The lid 33 can be opened and closed by a hinge 32. When the lid part 33 closes the opening of the storage part 31, the space in the storage part 31 is substantially closed. At a substantially central part of the lid 33, a small hole 34 penetrating the lid 33 is provided. As described later, the small holes 34 function as steam exhaust means. One or more sheets of the wiping sheet 1 are stored in the housing 11 in a substantially sealed state, and after being heated to a predetermined temperature by a predetermined heating means in this state. Then, it is taken out of the storage body 11 and used for cleaning the body. As a heating means for the wiping sheet 1, an appropriate means is used according to the material of the container. For example, when the storage body 11 is made of a material that transmits electromagnetic waves, for example, various synthetic resins, the cleaning sheet 1 is stored in the storage body 11, and then the storage body 11 is heated in a microwave oven. The wiping sheet 1 can be heated by placing it in the inside and irradiating it with electromagnetic waves. If the container is made of a material that is not permeable to electromagnetic waves, for example, metal, the cleaning sheet 1 is stored in the container 11 and then the container 11 is immersed in hot water to remove the cleaning sheet. 1 can be heated. Regardless of which heating means is used, the housing 11 must be heat-resistant. The heating temperature of the wiping sheet 1 is 35 to 85 ° C, preferably 40 to 80 ° C, and particularly preferably 50 to 75 ° C. Preferred from the point. When the wiping sheet 1 is heated while being substantially sealed in the housing 11, steam is generated from the aqueous cleaning agent impregnated therein, and the inside of the housing 11 is pressurized. When the internal pressure of the storage body 11 increases, the storage body 11 may be ruptured. Even if there is no rupture, when the temperature of the container 11 decreases to near room temperature, the pressure inside is reduced, and the container 11 is deformed. Therefore, it is preferable to release a part of the generated steam to make the internal pressure of the housing 11 equal to the atmospheric pressure. From this point of view, after the wiping sheet 1 is heated to 75 ° C, the container 11 is stored for 4 minutes in an environment of 23 ° C and 65% RH, and then the container 11 is It is preferable that the housing 11 is provided with steam exhaust means capable of reducing the amount of evaporation of the aqueous cleaning agent to 1 to 20% by weight, particularly 2 to 15% by weight, particularly 3 to 12% by weight. In the present embodiment, as described above, the small hole 34 is provided in the lid 33 of the housing 11, and a part of the steam generated through the small hole 34 is discharged to the outside. It has become so. The diameter of the small holes 34 should be about 0.3 to 5 mm, especially about 0.5 to 4 mm, especially about 0.8 to 2.5 mm. This is preferable because the emission reduction amount can easily be within the above range. The steam exhaust means is not limited to a small hole, and may be, for example, a heat-resistant moisture-permeable film sheet. The wiping sheet 1 thus heated is stored in the storage body 11 until an actual wiping operation is performed, and the high temperature state is maintained for a long time. Then, when the wiping operation is performed, it is first taken out of the housing 11 and the body to be wiped is wiped. From this point of view, after the wiping sheet 1 is heated to 75 ° C, the container 11 is stored in the container 11 at 23 for 4 minutes in an environment of 65% RH. It is preferable that the storage body 11 has a heat retaining property capable of maintaining the temperature of the wiping sheet 1 at 40 ° C. or more, particularly 50 ° C. or more. In order to enhance the heat retaining property of the storage body 11, for example, the storage body 11 itself may be made of a material having high heat insulation, such as glass fiber, ceramic glass wool, styrene foam, or urethane foam, or the inner surface of the storage body 11. Insulation material, for example, Thermo-Wool (wool insulation material), Styrofoam, or Urethane foam may be attached. In addition, when the cleaning sheet 1 is directly heated without being stored in the storage body 11, the maintenance time of the high temperature state is relatively shorter than when the cleaning sheet 1 is stored in the storage body 11 and heated. . The shape of the storage body 11 is not limited to the shape shown in FIG. 6, and may be any shape as long as the cleaning sheet 1 can be housed in a substantially sealed state. In the following examples, "%" means "% by weight" unless otherwise specified.
