途への展開が進められている。2. Description of the Related Art In recent years, the awareness of health and hygiene has been increasing in accordance with the improvement of the standard of living of the people. Has been In particular, in the field of clothing, various deodorizing, antibacterial, and antifouling processing techniques have been developed for wearing. It is also being developed for other uses, including interiors.

However, in this method, deodorant, antibacterial,
In order to perform processing that satisfies antifouling properties, it is necessary to apply a large amount of a processing agent, and the productivity may deteriorate. Further, the texture may become hard due to an increase in the amount of adhesion, or the color may become white and the appearance may deteriorate depending on the processing agent.

化されることが知られている。[0004] The deodorants used in these are:
Except for a very small portion, it is mainly due to neutralizing action, etc.
It cannot exert a sustainable deodorizing function. For example, acidic titanium oxide, aluminum sulfate and the like are effective in deodorizing basic ammonia and the like, but are ineffective against neutral malodor. Zinc oxide, which is a basic deodorant itself, is ineffective against neutral malodor even if it neutralizes acidic malodors, such as methyl mercaptan and hydrogen sulfide, and changes them into odorless substances. In addition, in the deodorizing method by the neutralizing action using these acids and bases,
If the deodorant itself is saturated, the effect cannot be exerted, and the function is restored only after processing such as washing. Therefore, these deodorants have a limited ability to treat odors and cannot exert any effect on basic or acidic substances. In addition, deodorants utilizing physical adsorption such as activated carbon and silica are also known. These concentrate the malodorous components in the deodorant and reduce the concentration in the surroundings, but they do not provide an essential solution since the total amount of the malodorous components does not decrease. Ideally, it is necessary to decompose malodorous components to completely odorless components, and very few chemicals are known to perform such an action. For example, there is iron / phthalocyanine, which is enzymatically oxidatively degraded. This substance is kneaded into rayon fiber and used, for example, in futon wool, which confirms that ammonia is deodorized. Have been. It is known that hydrogen sulfide is oxidized to sulfur, mercaptan is oxidized to disulfide, aldehyde is oxidized to carboxylic acid, and amine is oxidized to ketone and ammonia.

That is, it is not effective in removing tobacco odor or sweat odor. Further, it is said that the combined malodor, for example, the combustion gas of tobacco contains thousands of components, and it has been difficult to deodorize all of them.

防止効果があることが多く見受けられる。Further, there is no effective deodorant for isovaleric acid, which is a main component of humans, and the odor component of axillary odor is a mixture of several types of lower fatty acids, which completely deodorizes them. It was difficult. Such deodorizing processing can remove or reduce odor components in the air by decomposition or adsorption, but the deodorized fiber structure rather adsorbs odor components or changes to other components by decomposition. However, an unusual odor component may be generated. Therefore, at this time, the odor component cannot be completely removed. Rather, it is often found that a fiber structure that has not been deodorized has a more effective odor prevention effect.

However, in order to fix the titanium oxide photocatalyst to the fiber, some kind of binder is required. Resin is required,
Conventionally used binder resins such as acrylic resins and urethane resins are resins containing organic hydrocarbons, so the binder resin is decomposed by the strong oxidative decomposition power of the titanium oxide photocatalyst, causing coloration and odor. And so on.

かった。Further, the fiber itself provided with the titanium oxide photocatalyst may deteriorate, causing problems such as coloring, reduction in strength, and generation of malodor due to generation of decomposition products having a low molecular weight. A technique for imparting a function such as deodorization by using a method has not yet been put to practical use. Heretofore, as an example in which a titanium oxide photocatalyst is used, there is no example in which a titanium oxide photocatalyst is fixed on the surface of an inorganic substance such as ceramic or glass, but is fixed on the surface of an organic substance.

い。The inert titanium oxide used for the polyester fiber is a titanium oxide which is inactive without being excited by light of a specific wavelength, particularly preferably ultraviolet light, and is preferably used for producing a polyester synthetic fiber. Titanium oxide used as a matting agent is used. By adding such inert titanium oxide, organic 1
The addition of inorganic titanium oxide to 00% of the polyester fibers enhances the inorganic properties, and the effect of reducing the effect of the redox action of the photocatalytic semiconductor used for the upper layer on the polyester fibers is caused. Is what you do.
Such an inert titanium oxide can be added at the time of polymerization of the polyester fiber, and has an average particle size of preferably 0.1 to 0.7 μm, more preferably 0.2 to 0, from the viewpoint of spinning properties and yarn physical properties. A range of 0.4 μm is preferable. Also,
The amount of the inert titanium oxide to be added is 0.3 to 5% by weight, preferably 0.5 to 4% by weight based on the weight of the fiber.
What is contained is used. If the content is less than 0.3% by weight, the polyester fiber is easily decomposed by the photocatalytic semiconductor, and the photocatalytic function and the physical properties of the fiber structure cannot be maintained with good durability. 5% by weight

ない。The above-mentioned irregular cross-sectional modulus of the polyester fiber is defined as the outer peripheral length of the irregular cross-sectional yarn and the outer peripheral length of the perfect circular cross-sectional yarn having the same cross-sectional area as the true circular cross-sectional yarn, that is, the same denier. , And specifically,
It is represented by a value obtained by dividing the outer circumference of the modified cross-section yarn by the outer circumference of the round cross-section yarn. As the numerical value increases, the surface area per yarn weight increases, and the area of the layer of the optical semiconductor increases accordingly, so that the functionality of the present invention is correspondingly increased. As such deformed section modulus, 1.2 to
2, preferably in the range of 1.3 to 1.8. If it is less than 1.2, it is close to a circular cross section, and the effect of the functionality cannot be expected much. On the other hand, if the number exceeds 2, it is difficult to form a cross-sectional shape in the spinning of the polyester fiber, which is not preferable from the viewpoint of productivity.
