BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail.

[0011] The bedding of the present invention comprises a fiber as a main constituent material, and at least one binder selected from an alkyl silicate resin, a silicone resin and a fluorine resin on the fiber surface, It has a photocatalyst.

In the present invention, the photocatalytic agent has a property of being excited by ultraviolet rays and oxidatively decomposing organic substances by a strong oxidizing power. Specifically, the photocatalytic agent has a crystal structure called anatase type or rutile type. Includes what you have.

In the bedding of the present invention, attention is paid to the fact that such a photocatalytic agent has deodorizing properties, colored matter decomposition / removal properties (antifouling properties), and bactericidal properties (antibacterial and antifungal). It is applied to bedding and utilized.

The action of such a photocatalyst is that sweat odor (main component: ammonia and isovaleric acid) is generated in the water emanating from the eccrine glands and apocrine glands under the skin due to resident bacteria around the skin. the smell is excited by photocatalyst a · OH group (hydroxyl radicals) touched the main component of sweat, which CO ₂
(Carbon dioxide) and H ₂ 0 (water) and deodorize.

[0015] In addition, the aging odor (middle and old odor) is mainly composed of nonenal, the elderly odor (middle and old odor) is mainly composed of indole and skatole, the fecal urine odor is mainly composed of ammonia, and the other body odors. Acetaldehyde and methyl mercaptan as main components, and nicotine as a main component in cigarette odor can be decomposed with a photocatalytic agent, respectively.

In the present invention, among such photocatalysts, it is preferable to use a composite oxide comprising titanium and silicon.

Such a composite oxide is disclosed in, for example,
A catalyst prepared by the method described in Japanese Patent No. 55184 may be used. In general, a binary composite oxide composed of titanium and silicon is, for example, a “catalyst” (Vol. 17, No. 3,
As described on page 72 (1975, published by the Catalysis Society of Japan), it is known as a solid acid, and the ratio of titanium to silicon is 20 to 95% in terms of oxide in terms of oxide.
Mol% and silicon oxide are preferably in the range of 5 to 80 mol%.

The particle diameter of such a photocatalyst is too large,
When the specific surface area is too small, the decomposition rate for organic substances, particularly bacteria, tends to decrease. Further, in the deodorizing reaction, as described above, the malodorous component is adsorbed on the catalyst, and thereafter,
It is thought that this undergoes a process of undergoing ultraviolet oxidative decomposition, and the quality of adsorption of the malodorous component is considered to greatly affect the deodorizing efficiency. According to the findings of the present inventors, the primary particle diameter is preferably 20 nm or less, more preferably 1 nm or less.

The amount of adhesion of such a resin is preferably used in the same amount as that of the silicone resin.

Further, it is preferable to further add zeolite to such a binder, because it has an effect of further improving antibacterial performance.

That is, it has the effect of improving the adsorptive power of odorous components and increasing the ratio of inorganic components in the structure, thereby suppressing decomposition by the photocatalyst. Such zeolites include gold, platinum,

Under conditions of log (B / A)> 1.5, log (B / A
C) was defined as the difference in the number of bacteria, and 2.2 or more was regarded as a pass.

Here, A is the number of bacteria recovered and dispersed immediately after inoculation of the unprocessed product, B is the number of bacteria recovered and recovered after 18 hours of cultivation of the unprocessed product, and C is the number of bacteria recovered after 18 hours of cultivation of the processed product. The numbers of the collected bacteria are shown. [F] Antifouling evaluation method Step 1: 100 ° C. × polyethylene bag (20 liters)
