In addition, when used, the hygroscopic sheet can be connected or removed so that it can be used for futon, entrance, bath, crib, closet, closet, pet use, etc. it can.

  Hereinafter, a moisture absorption mat according to an aspect of the present invention will be described with reference to the drawings. In addition, this invention is not limited to the following embodiment.

1. Overall Configuration As shown in FIG. 1, the hygroscopic mat 100 of the present embodiment is configured by arranging three hygroscopic sheets 1 in the short direction and connecting them by a connecting portion 2. Moreover, since the moisture-absorbing mat 100 can be connected to or removed from each moisture-absorbing sheet 1, it can be used for futons, entrances, baths, baby beds, closets, closets, pets, etc. Can be used.

2. Hygroscopic sheet The hygroscopic sheet 1 has a rectangular shape as shown in FIGS. 1 and 2, and has four rounded corners. The outer peripheral surface 1a of the moisture absorbent sheet 1 is reinforced with an edge.

  The moisture absorbing sheet 1 is flexible and air permeable, and has a material having a moisture absorbing function inside.

  For example, as shown in FIG. 3, the moisture-absorbing sheet 1 includes a base material sheet 12 and a base material sheet 13 that are superposed, and a plurality of granular silica gels 16 between the superposed surfaces 14 and 15. Is sandwiched to form the moisture absorption layer 11. The moisture-absorbing sheet 1 is produced, for example, by sandwiching a large number of granular silica gels 16 between the substrate sheet 12 and the substrate sheet 13 and fixing them by sewing or heat welding to form the moisture-absorbing layer 11. be able to.

2-1. Base Material Sheets The base material sheets 12 and 13 are not particularly limited, but preferably have air permeability and allow air and moisture to permeate. For example, a nonwoven fabric, a woven fabric, a knitted fabric, or the like is used. As the material of the base sheet 12, 13, for example, a polyester resin such as polyethylene terephthalate (PET) or a synthetic resin such as polypropylene resin can be used. The base sheet 12 is an aggregate of webs 17, and the base sheet 13 is an aggregate of webs 18.

2-2. Moisture Absorbing Layer The material of the moisture absorbing layer 11 is not particularly limited as long as it has a moisture absorbing function. For example, silica gel, natural porous stones such as zeolite and tourmaline, charcoal materials such as Bincho charcoal, activated carbon, perlite, and sodium silicate. Etc. These can be used alone or in combination of two or more. Among these, silica gel is preferably used because it is excellent in moisture absorption and deodorization functions and has immediate effect. Silica gel also adsorbs ammonia, trimethylamine, hydrogen sulfide, mercaptan, which is the source of odors scattered in the air, and non-nal gas that causes aging odors, and has a deodorizing function.

  As shown in FIG. 3, the moisture absorption layer 11 has a layer shape between the base material sheets 12 and 13, and is a large number of silica gels uniformly distributed over the entire opposing surfaces 14 and 15 of the base material sheets 12 and 13. 16 aggregates. In a state where the silica gel 16 is sandwiched from both the upper and lower sides, the opposing surfaces 14 and 15 of the base sheets 12 and 13 are enlarged as shown in FIG. 3, and the webs 17 and 18 which are constituent materials of the base sheets 12 and 13 are shown. Are stitched together.

  In order to fix the silica gel 16, needle punches are applied to a polymerization portion between the base sheet 12 and the base sheet 13 at a plurality of locations in a state where the silica gel 16 is sandwiched from both the upper and lower sides. That is, the webs 17 and 18 of the base sheet 12 and the base sheet 13 are mechanically entangled at each needle punch location, so that the base sheet 12 and the base sheet 13 are joined in the vicinity of the entangled portions. It is fixed. As a result, the silica gel 16 is held in a non-movable state while being layered by the base material sheet 12 and the base material sheet 13 that are sewn between the opposing surface 14 and the opposing surface 15 by the webs 17 and 18. .

The particles of the silica gel 16 have a large number of fine through holes, and have a function of absorbing moisture in the air by surface adsorption or capillary action in a high humidity atmosphere and releasing the absorbed moisture in a dry atmosphere. ing. Therefore, in order to improve the moisture absorption function and the moisture release function, the silica gel 16 in the present embodiment has a fine space volume of 0.5 to 1.0 ml / g and a surface area of 650 to 350 m ² / g. The thing is adopted.

  In addition, a fine through hole having a diameter of 30 to 120 angstroms is preferable in order to exhibit a moisture absorption function and the like.

  As described above, since a large number of particles of the silica gel 16 are sandwiched between the base sheet 12 and the base sheet 13, high hygroscopicity, moisture proofing, and deodorizing properties can be maintained for a long time.

  When the moisture absorbing sheet 1 is dried in the sun, the moisture absorbing function is regenerated and can be used repeatedly.

  Although the dimension and shape of the moisture-absorbing sheet 1 are not particularly limited, a rectangular shape is preferable, and is usually 80 to 100 cm (long side) × 50 to 70 cm (short side) × 0.7 to 0.9 cm (thickness). Preferably, it is 90 cm (long side) × 60 cm (short side) × 0.8 cm (thickness). By making the dimension of the long side of the moisture absorbent sheet 1 approximately the same as that of the half of the bran, it is possible to make the dimension suitable for pressing.

  Also, as shown in FIG. 1, when three moisture absorbent sheets 1 are connected, the size becomes the same as that of an adult futon, and the size can be made suitable for a futon hygroscopic mat (adult). Further, when two hygroscopic sheets 1 are connected, the size becomes the same as that of a children's futon, and the size is suitable for a hygroscopic mat for children (for children).

  When the dimension of the moisture absorbent sheet 1 is 90 cm (long side) × 60 cm (short side) × 0.8 cm (thickness), the moisture absorption amount of the moisture absorbent sheet 1 is about 260 ml. The moisture absorption amount of the moisture absorbing mat 100 formed by connecting the three moisture absorbing sheets 1 is about 780 ml.

3. Surface fastener On the long side of the moisture absorbent sheet 1, there are two surface fasteners 2 in total, one on each side. Also on the long side of the moisture absorbent sheet 1 facing each other, two hook-and-loop fasteners 2 are provided on each of the left and right sides in total. Therefore, the hygroscopic sheet 1 has a total of four surface fasteners 2.

  The surface fastener 2 has, for example, one side 2a having hook-like raised portions and the other 2b having raised portions densely formed in a loop shape. When both are pressed, the hook-like raised portions and the raised pieces densely formed in a loop shape are entangled. It expresses a fixing force and can be affixed or removed freely by human power.

  By attaching the surface fastener 2a of one moisture absorbent sheet 1 and the surface fastener 2b of the other moisture absorbent sheet 1, as shown in FIG. 1, the three moisture absorbent sheets 1 can be detachably arranged side by side in the lateral direction. Can be linked. Therefore, the hook-and-loop fastener 2 has a role of an attaching / detaching portion.

4). Moisture absorption sensor The moisture absorption sensor 3 is obtained by, for example, applying a predetermined amount of cobalt chloride on the surface. When cobalt chloride is anhydrous, the color is blue, and when the humidity in the atmosphere increases and becomes dihydrate, it becomes purple, and when the humidity further increases, it becomes hexahydrate and becomes pink. A person can recognize the degree of moisture absorption by visually recognizing this discoloration. If it is determined that the degree of moisture absorption has increased due to discoloration, it can be dried with reference to the color change using means such as sun drying or a dryer.

  Although there is no limitation in particular about the position which provides the moisture absorption sensor 3, it is preferable to provide in the peripheral part instead of the center part of the moisture absorption sheet 1. FIG.

5. Applications The moisture absorbent mat of the present embodiment can be used for applications such as futons, entrances, baths, cribs, closets, closets and pets. Since the moisture absorption mat of this embodiment is excellent in the moisture absorption effect, if it is used under the futon (bed mat) and used as a futon mat, a large amount of moisture from the futon and unpleasant stuffiness on the futon are removed, and the futon is slatted. can do. In addition, it can exhibit a great deodorizing effect with only a few tens of minutes against acetic acid gas and nonenal gas, which are unpleasant odors (sweaty odor / aging odor). Therefore, it is also effective for the smell of pee due to incontinence (ammonia gas). Furthermore, it has a humidity control effect that adjusts the humidity of the bed and futon, and the humidity control function of the silica gel can also prevent the generation of mold and mites. In addition, VOC (volatile organic compounds) such as formaldehyde and toluene, which are the cause of sick house, can be adsorbed quickly.
