DESCRIPTION OF THE PREFERRED EMBODIMENTS The applicant has filed Japanese Patent Application No.
In Japanese Patent Application No. 352018, a woven fabric woven using a yarn for organic matter decomposition photocatalyst having a titanium dioxide layer on the surface has been proposed. The applicant applied the woven fabric thus formed as a cloth for a wall to one surface of a wall panel with an adhesive, and conducted an experiment on the use of the woven cloth as a cloth for a wall. It was found that a photocatalytic reaction was caused by the irradiated light, and the woven fabric was easily detached from the wall panel. That is, the titanium dioxide layer formed on the surface of the yarn of the woven fabric by the light irradiated on the woven fabric causes a photocatalytic reaction,
This is because it is recognized that the organic substance constituting the adhesive is decomposed to reduce the adhesive strength of the adhesive. The applicant has sought an inorganic adhesive that can be used in this kind of woven fabric in order to overcome such a problem, but almost no inorganic adhesive having adhesive strength exists. I was struggling to respond.

As shown in FIG. 3, the woven fabric 1 which has been subjected to the coating step and the drying step is processed at a processing temperature of 450 ° C. to 65 ° C.
It is supplied into a high-temperature furnace heated to about 0 ° C., and is shifted to a heating step shown in FIG. The heating time is suitably about 30 minutes. In the woven fabric 1 thus treated at a high temperature, the titania gel applied to one side is changed into titanium dioxide (TiO2), and as shown in FIG. Then, the titanium dioxide layer 6 is fired. As shown in FIG. 3, the coating step, the drying step, and the heating step are usually performed in 3 to 5 times.
This is repeated about once, whereby the layer pressure and coating amount of the titanium dioxide layer 6 gradually increase. As shown in part A of FIG. 4, the titanium dioxide layer 6 has a layered shape attached to the surface of the yarn constituting the woven fabric 1 in a patchy manner, and external light is appropriately applied to the woven fabric 1 made of glass cloth. It can be transmitted. The titanium dioxide layer 6 on one side of the woven fabric 1
In order to increase the layer pressure of, or to increase the area of the patchy titanium dioxide layer 6 on the outer surface, a method of increasing the number of repetitions of the coating step or the drying step and the surfactant in the coating material 2 There is a method of selecting one having a higher emulsion property.

That is, the woven fabric 1 provided with the titanium dioxide layer 6 on one side in this way can transmit external light not only from the end but also from the back surface not provided with the titanium dioxide layer 6. Photocatalytic phenomena can be generated in the titanium dioxide layer 6 even with specially prepared illumination light such as an ultraviolet irradiation lamp, sunlight, or indoor light. That is, in this phenomenon, light γ transmitted through the woven fabric 1 made of glass cloth becomes energy, and an oxidation-reduction action occurs in which electrons and holes are generated in the portion of the titanium dioxide layer 6, which is formed in this manner. The woven fabric 1 can be used for various applications. For example, by using as a cloth for curtains, sunlight is mainly irradiated on the back side of the woven fabric 1,
A more vigorous photocatalytic reaction can be obtained. In addition, since the titanium dioxide layer 6 is provided only on one side, even if an adhesive (organic) is applied to the back side not having the titanium dioxide layer 6 and attached to a wall or panel, the back side may be provided. Since the photocatalytic reaction for decomposing the organic substance does not occur, the adhesive component is not decomposed. Therefore, it is suitable for use as a wall cloth, a ceiling cloth, a hermetic seal for a wound, and the like.
