  However, in the conventional water absorbing device, the deodorizing effect of activated carbon is greatly reduced by moisture, so it is difficult to completely prevent malodors due to the treatment of excrement such as urination and defecation, and the manufacturing process is complicated. In addition, there is a problem that it cannot be processed into a desired shape. In addition, the conventional water-absorbing device absorbs moisture but has almost no antibacterial effect, so that various fungi are easy to propagate, and also visually uncomfortable and unclean.

  Therefore, the present invention was created in view of the conventional problems as described above, and can be easily processed into a desired shape with a simple manufacturing process. An object of the present invention is to provide a water absorbing device capable of efficiently absorbing water such as excreta excrement and body fluids, removing almost completely bad odor, and at the same time exhibiting an antibacterial effect.

  For this reason, the present invention is a water absorbent 1 in which the water absorbent 3 is covered with a liquid impermeable back sheet 8 and a liquid permeable front sheet 7, and the water absorbent 3 is preliminarily provided with the antibacterial agent 9. Similarly, the above-described problem was solved by including the adsorbent 4 impregnated with.

  That is, in the water-absorbing device according to the present invention, for example, silica gel, which is an adsorbent 4 contained together with a water-absorbing body 3 made of a mixture of pulp, polymer, etc. A water-absorbing device body 1 for releasing and releasing 9 molecules of antibacterial agent with methylene blue that has been adsorbed efficiently such as bodily fluids and at the same time soaked in silica gel is easily processed and formed into a desired shape by a simple manufacturing process. Let And since the blue particle | grains of the silica gel which soaked the methylene blue with respect to the water absorption tool main body 1 are arranged, the effect which gives a visually clean feeling compared with the past is exhibited.

  The present invention is configured as described above, and has excellent deodorizing properties and moisture absorption compared to conventional ones. Therefore, it efficiently absorbs moisture such as manure excrement and body fluids by small animals and the human body and has a bad odor. Can be removed almost completely, and at the same time, the water-absorbing device main body 1 that makes it possible to exhibit the antibacterial effect of methylene blue can be easily processed and formed into a desired shape by a simple manufacturing process. In addition, since silica gel is made of blue particles in which methylene blue is impregnated into a white sheet, it can be molded to provide a visually clean feeling.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. Reference numeral 1 shown in the figure denotes a pet cage that is a small animal such as a dog, a cat, a rabbit, a small bird, or a hamster, or for excretion. It is laid on the floor of the toilet and in the house, or worn on the human body as a disposable diaper for adults, a surgical pad, a sanitary napkin, etc., to absorb moisture such as manure excrement and body fluids. The main body of the water absorbing device is formed in a sheet shape to prevent bad odor.

  As shown in FIG. 1, the manufacturing process of the water-absorbing device main body 1 includes, as a first step, a starch-polyacrylic acid graft copolymer obtained by graft-polymerizing acrylic acid to starch, for example, and a crosslinking agent containing acrylate as a main component. Of water-absorbing polymer such as starch-methacrylate graft cross-linked product added with sucrose and powdered polymer such as acrylic acid polymer, and pulverized pulp or cellulose powder having a function of diffusing absorbed urine moisture The water absorbing body 3 is formed by the body.

  As a second step, porous adsorbent 4 made of, for example, silica gel, acrylic resin or the like having a large specific surface area and high adsorption ability is impregnated with methylene blue or the like as a basic dye in advance.

  As the third step, the adsorbent 4 and the water absorbent 3 are mixed on the inclusion paper 2 in advance and then sprayed or sprayed separately.

  As a fourth step, water-absorbing paper 5 such as tissue paper is placed on the spray and covered.

  As a fifth step, the water absorbing / adsorbing member 6 is formed by thermocompression bonding with an embossing roll or the like after being covered and integrated.

  After the water absorption / adsorption member 6 is cut to an appropriate size as the sixth step, for example, synthetic resin fiber, rayon fiber, polyester fiber, polyolefin fiber, hydrophilic fiber, surfactant-treated / silica-treated thermoplastic fiber, cotton interview Impervious material made of natural fiber such as cotton, non-woven fabric such as cellulose fiber and pulp fiber, white surface sheet 7 with water permeability and high density polyethylene, polyethylene having about 1.5 mil emboss sky bath, polypropylene, etc. A water-absorbing tool main body 1 (see FIG. 2) is formed by covering with a liquid white backsheet 8 and fixing with a heat seal (not shown).

  The packaged product of the water-absorbing device main body 1 is constituted by the folding step and the bagging step for setting the shipping state as the seventh step.

  As the antibacterial agent 9 soaked in the adsorbent 4 such as silica gel or acrylic resin, for example, methylene blue which is a pure blue basic dye, the adsorbent 4 adsorbs water such as manure excrement and body fluids simultaneously with moisture. Antibacterial molecules from methylene blue generated by contact reaction with water are divergently released. At this time, the shape of the adsorbent 4 may be a crushed powder, a scale, or a sphere. For example, in the case of a powder, the particle diameter is preferably about 0.3 to 1.5 mm is optimal.

  The adsorbent 4 impregnated with the antibacterial agent 9 is optimally contained in the water absorbing body 3 in an amount of about 12 to 18% by weight. In addition, the adsorbent 4 may be a hygroscopic inorganic clay-like material such as activated carbon, diatomaceous earth, bentonite, zeolite, vermiculite, kaolin, kaolinite, talc, and the like, and further, a water absorbing / adsorbing member 6. An aromatic diffuser or the like may be contained inside.

  In addition, the length and width of the water absorbing / adsorbing member 6 to be cut can be set to various sizes depending on the application. For example, the water absorbing / adsorbing member 6 is cut into a bendable circular or rectangular sheet or chip. Can do.

  In addition, the material of the said inclusion paper 2, the kind of the polymer which forms the water absorbing body 3, the material of the water absorbing paper 5, the material of the front sheet 7, the back sheet 8 and the like are used together with the type of the antibacterial agent 9 in the present embodiment. Of course, other materials and materials other than these may be used.

  Next, an example of use of the present invention will be described. For example, in a breeding cage, a toilet for excretion, or on a floor surface in a house, a pet animal such as a dog or a cat urinates or defecates a water absorbing device. The main body 1 is laid or worn on the body as a disposable diaper for adults, a surgical pad, a sanitary napkin, or the like.

  When the pet animal excretes on the water-absorbing device main body 1 or is excreted during human wear, the liquid component contained in the excreta is absorbed by the water-absorbing body 3 and is the adsorbent 4 contained together with the water-absorbing body 3. Silica gel adsorbs water such as manure excrement and body fluids, and at the same time, methylene blue that has been soaked in silica gel reacts with water to release and diverge antibacterial molecules to the surrounding area to generate an antibacterial effect. At this time, since the entire adsorbed portion of the water absorbing device main body 1 is colored blue by blue particles of silica gel in which methylene blue is impregnated into the front sheet 7 and the back sheet 8 on a white background, it visually presents a clean feeling. Become.
