BEST MODE FOR CARRYING OUT THE INVENTION An antibacterial clothing label (1) of the present invention will be described below with reference to the drawings.

Referring to FIG. 1, there is shown a cross-sectional view schematically showing the label for antibacterial clothing of the present invention in which a sheet-like woven fabric (2) is provided with an indication receiving layer (3) on one surface. Further, referring to FIG. 2, there is shown a cross-sectional view schematically showing the label for antibacterial clothing of the present invention in which the display receiving layer (3) is provided on both surfaces of the sheet-shaped fabric (2). As described above, the label (1) for antibacterial clothing of the present invention comprises the sheet-like woven fabric (2) and the display receiving layer (3) provided on one side or both sides thereof.

First, the woven fabric used as the sheet-like woven fabric (2) is not particularly limited, and synthetic fibers such as nylon and polyester, natural fibers such as cotton and hemp, and their blended and woven fabrics. Is preferably used.

Next, the display receiving layer (3) is a layer for receiving the display when the display is provided on the clothing label by printing or heat transfer.

A first example of a display receptive layer is a printable layer. This printable layer is offset printing,
When printing by ceiling printing, screen printing, etc.,
This is for appropriately receiving the display by ink.
Such a printable layer is for imparting ink absorbability to the surface of the woven fabric, imparting ink display receptivity, or imparting additionally required smoothness.

Examples of the printable layer include, for example,
In order to impart mainly ink absorbency, a filler having ink absorbability such as calcium carbonate, silica, clay, etc. is contained in polyacrylic acid ester resin, polyurethane, polyamide, polyester or the like alone or in a mixture thereof. Layers. The thickness of the layer containing the ink absorbing filler is generally in the range of 3 to 100 μm.

Further, as an example of the printable layer mainly for imparting ink display receptivity, polyacrylic ester resin, polyurethane, polyamide, polyester or the like alone or in a mixture thereof, a filler such as calcium carbonate, silica or the like is used. A layer having a composition such as a coating material containing Such layers are generally 3-100 [mu] thick. At the same time, any of the printable layers described above also imparts smoothness.

A second example of a display receiving layer is a thermal transfer receiving layer. The thermal transfer receiving layer is for receiving the display when printing by melt thermal transfer, and imparts such acceptability and smoothness to the surface of the woven fabric. Examples of such a thermal transfer receiving layer include polyurethane, polyester, polyacrylic acid ester, polyvinyl chloride / polyvinyl acetate copolymer, and polyvinyl chloride / ethylene copolymer coated on a cloth and finished smooth. Can be mentioned.

In the label for antibacterial clothing of the present invention, a silver silica gel antibacterial agent is contained in both the sheet-like fabric and the display receiving layer. Thus, not only the display-receiving layer on the surface but also the sheet-like fabric as the base material contains the antibacterial agent, so that the antibacterial property can be continuously exhibited.

In the present specification, the "silver silica gel-based antibacterial agent" refers to a material in which a silver thiosulfato complex salt is contained in porous silica gel and the surface of which is coated with a silica-based substance (see, for example, Japanese Patent Application Laid-Open No. Hei 10 (1999) -242242). 5-155735
No., JP-A-5-201817).

The thiosulfato silver complex salt contained in the silver silica gel antibacterial agent can be obtained by reacting a silver salt with a thiosulfate. For example, sulfite and / or hydrogen sulfite are added to an aqueous solution of silver salt to react, and then thiosulfate is added. Alternatively, it can also be obtained by adding a silver salt to an aqueous thiosulfate solution.

The obtained silver thiosulfato complex salt is supported on a porous silica gel carrier. The loading can be carried out by mixing an aqueous solution of a thiosulfato silver complex salt or an alcohol solution with a silica gel carrier and drying.

Further, the surface of the carrier is coated with a silica-based substance by utilizing hydrolysis of the reactive organosilicon compound.

The silver silica gel antibacterial agent used in the present invention can be easily obtained as a commercial product under the trade name "Amenitop (made by Matsushita Electric Industrial Co., Ltd.)".

The label for antibacterial clothing of the present invention is generally manufactured as described below. First, the fabric containing the antibacterial agent is obtained by impregnating the fabric with the antibacterial agent. Specifically, the woven fabric is dipped and impregnated in a liquid obtained by adding an antibacterial agent Amenitop to a resin such as polyacrylic acid ester, polyurethane or polyester.

As an alternative method, a woven fabric woven with a yarn containing an antibacterial agent and spun, or a yarn coated with an antibacterial agent after spinning is used.

Next, the printable layer is composed of, for example, a polyacrylic acid ester containing an ink absorbing filler,
It is produced by applying a coating material such as polyurethane, polyamide, polyester resin or the like alone or a mixture thereof to a woven fabric by using a doctor knife coating, drying, and calendering.

Further, as another example of the thermal transfer receiving layer, a composition: paint made of polyacrylic ester, polyurethane, polyester resin, or composition: paint made of polyurethane resin with filler such as calcium carbonate or silica is used as a doctor. It is formed by applying using knife coating or the like, drying and calendering. The thickness of such a thermal transfer receiving layer is generally in the range of 3 to 100 μm.

The thus obtained label for antibacterial clothing of the present invention is suitably used for clothing containing an antibacterial agent in order to improve the overall hygiene aspect. In the present specification, the term "for clothing" includes clothing such as shirts, underwear, and
It is a concept that includes not only outerwear but also sheets, curtains, blankets, and futons.

The present invention will be described in more detail below with reference to examples.
