However, chlorine-based liquid detergents such as those disclosed in JP-A-4-501125, JP-A-5-123358 and JP-A-6-41588 disclose disinfection, disinfection, and the like. Although excellent in bleaching or mold removal, there is a danger of liquid dripping when cleaning vertical surfaces, and there is a risk of damaging eyes and skin. In addition, since it has a strong chlorine odor, it is necessary to pay sufficient attention to ventilation when using it, and there is a problem that harmful chlorine gas is generated when used in combination with an oxygen-based cleaning agent by mistake. Further, in the past, a sheet-like cleaning tool containing a chlorine generating agent has also been proposed, but until a dirt component or mold is decomposed.
Must be fixed by hand. Further, Japanese Unexamined Patent Application Publication No. 7-26
No. 5397 discloses a sheet-like article using chitosan or Ag-supported zeolite, but has a problem that the antibacterial and antifungal effects are insufficient.

The present invention has been made in view of the above problems, and has an excellent disinfecting, disinfecting, bleaching or mold removing effect, has no risk of liquid dripping, may damage eyes and skin, and may generate chlorine gas. It is an object of the present invention to provide an oxygen-based cleaning tool without any defects.

[0005]

In the present invention, in order to achieve the above object, a first and a second support layer are interposed between the first and the second support layers via an adhesive polymer. And an oxygen-based activating substance that is retained and activated by moisture. The first and second support layers were dried, covered, melt-blown, spunbonded, wet-crossed, and hydroentangled powdered. Non-woven, woven, paper of other types
It is preferable to use a sponge or a synthetic resin film (for example, a wet-strength material, a thick-walled material, or a dried paper). Further, it is preferable that the oxygen-based activating substance is a peroxy compound which is far superior in antibacterial effect and antifungal effect as compared with chitosan and zeolite carrying Ag.

Here, as the first and second support layers in the claims, a hydrophobic or impermeable material, an absorptive sheet or the like can be used. The adhesive polymer is preferably a hot melt powder adhesive of copolyester, copolyamide, or polyethylene, or ethylene vinyl acetate (EVA), a hot melt powder adhesive, or a modified EVA hot melt powder adhesive. In particular, the range of 50 to 300 microns is preferable. The hot melt powder adhesive is mixed with the solid particles containing the peroxin compound before using the hot melt powder adhesive to bond the first and second support layers.

[0007] Peroxy compounds include free compounds,
Hydrogen peroxide generation systems, peroxy acids and their salts, and mixtures thereof. Sources of hydrogen peroxide include peroxides of alkali metals, organic peroxides such as urea peroxide, and inorganic peroxides such as alkali metal perborates, percarbonates, perphosphates, and persulfates. Salt. Two or more of these compounds may be mixed. Among them, particularly preferred are sodium percarbonate, sodium perborate and sodium persulfate.

If the amount is less than 50 g, the bleaching or mold removing effect is significantly deteriorated. If the coating amount is more than 50 g, not only the effect is not improved but also the sheet becomes rigid. In addition, it is preferable to take into consideration the melting viscosity, the melting temperature range, the melt viscosity for the powder adhesive, and the melt index.

[0010] In addition to polyesters, which are preferred examples of powder adhesives, or polyamides, other polymers having suitable properties can be used. Further, these are not limited to polycaprolactone. Such a powder adhesive has a melting point in the range of 50 to 200 °, that is, a melting temperature range, and when used, it must be lower than the melting point forming the support layer. When using synthetic fibers for the support layer, the hot melt powder adhesive is preferably a low-temperature adhesive polymer having a melting point of about 20 to 30 ° lower than the melting point of the fibers in order to prevent damage. Care must be taken to ensure the best adhesion compatibility between the powder and the support layer fibers. The preferred low temperature powder adhesives described above can maintain adhesive strength when the laminated sheet is wetted with water. The peroxy compound preferably activates when it becomes moist with water.

In addition to the above, the peroxy compound can be used as a solid or by adsorbing it on a suitable carrier and used as a powder or granules. Also, the peroxy compound may be used in combination with other compounds, for example, a surfactant such as sodium alkylbenzenesulfonate or sodium lauryl sulfate, or an alkaline substance such as sodium carbonate, sodium metasilicate, or sodium sulfate. it can. Other compounds that can be used in such a form include very hygroscopic polymers, fragrances, fragrances, abrasives, or dyes.

In the present invention, a peroxy compound is an essential component, but a metal complex and / or a polyacid may be further added to improve the bleaching power or the mold removing performance. Examples of such a metal complex include those in which a ligand is bound around a central metal. Specifically, a bidentate ligand such as pyridine or ethylenediamine, a tridentate or more planar ligand such as terpyridine or porphyrin, a tridentate or more steric ligand such as a cyclic amine, or a binuclear determinant ligand is used. can give.

A transition metal in the II-VII valent oxidation state selected from Re, Ir, Pt, and Au is preferable. The metal complex having these ligands may be formed in advance or may be formed when wet. The metal complex having a ligand may be mononuclear or polynuclear. A binuclear or polynuclear metal complex can be formed depending on the type of ligand and the oxidation state of the metal. In the metal complex, the coordinating species and / or the bridging species form a bridge between the metal centers.

Examples thereof include phosphomolybdic acid, phosphotungstic acid, silicomolybdic acid, silicotungstic acid, phosphotungstomolybdic acid, phosphovanadomolybdic acid, phosphovanadotungstic acid, and sodium or ammonium salts thereof.

When a sheet is used for bleaching a hard surface,
By incorporating the dye into at least one of the support layers or mixing with the particles, the dye is bleached by peracid upon release, and the degree of deterioration in bleaching power can be determined by looking at the sheet. Hereinafter, the sheet according to the present invention used for bleaching a hard surface or the like will be described in more detail.

The sheet used for hard surface bleaching is produced by mixing a powdered peroxin compound with a low melting polyester bonding powder until a homogeneous mixture is obtained. This mixed powder is evenly spread or otherwise applied to a first support layer such as a web-like lightweight hygroscopic paper or non-woven fabric. And
The amount of peroxy compound available in the final product depends on the amount of powder applied, the ratio of powder adhesive to peroxy compound powder, or the speed of the type of web receiving the powder.

For example, when producing the oxygen-based bleached sheet according to the present invention, 20 g of powder composed of a mixture of 3 parts of a peroxy compound and 20 parts of a polyethylene powder adhesive per m ^{2 of} viscose nonwoven fabric is used. Apply at the rate of In this way, the powder application rate is 12 g / m ² for a nonwoven web moving at a speed of 30 m / min.
Becomes The ratio of peroxy compound to powder adhesive is 1:
It can be changed in the range of 40 to 1: 1. The weight of the support layer, it can be changed from 1 m ² per 10g to 80 g, the range of 30g is preferably from 1 m ² per 15 g. Further, the amount of powder applied can be changed in the range of 1 g to 50 g per 1 m ² , preferably 5 g.
g to 35 g.

The support layer is selected from those described above. The second support layer is polymerized into the first support layer such that the powder mixture is sandwiched between the two layers, and heat and pressure are briefly applied. The heat applied is sufficient to fuse the powder adhesive to the support layer, the support layer, the peroxy compound,
Alternatively, it is set to such an extent that it does not adversely affect other chemicals mixed with these. By melting the bonding powder and subsequently bonding it together to the support layer, the peroxy compounds in the sheet are also bound and retained.

First, the peroxy compound is uniformly dispersed in the adhesive powder, and the resulting mixture is uniformly dispersed on the first support layer. Therefore, the peroxy compound is sufficiently and uniformly dispersed between the support layers. Thus, when a peroxy compound is used with a weak cellulosic material such as paper, the oxidizing power of this material does not adversely affect it. In addition, a quantitative peroxy compound can be bound between the support layers. This amount can vary widely. The sheet is suitable for sanitary use at the lower limit of the above range, and suitable for bleaching use at the upper limit of the above range.

The cleaning tool according to the present invention can be easily obtained by using an inexpensive support layer having good hygroscopicity, for example, a nonwoven fabric. And the cleaning tool according to the present invention has antibacterial properties, convenience, simplicity, and disposability,
Many consumers can easily purchase.
