[0002]

2. Description of the Related Art In recent years, awareness of sports, health and hygiene has been increasing with the improvement of the standard of living of the people.
In various fields of clothing, food and shelter, clothing products that have been subjected to deodorant, antibacterial, antifungal, and antifouling treatments have been put to practical use.

However, jackets, coats, skirts,
Pants, suits, blouses and other women's clothing, etc., have high deodorant, antibacterial and antifouling needs,
Processing technology has not been developed. For example, if you spend an indoor environment full of tobacco odors, such as pachinko and amusement arcades, or smoking vehicles on trains, etc. The body odor and sweat odor soak into clothing,
The stench that soaks into these clothes does not go away easily and is often unpleasant. If left untreated, dirt may not be removed or mold may occur. In addition, there is a great need for deodorizing unpleasant odors remaining on clothes, for example, when traveling abroad, such as when it is difficult to take effective measures for deodorizing such as washing.

[0004] In addition, in women's clothing such as blouses and dresses, it is not easy to leave the smell of sweat after sweating on summer commutes and going out, and to make the surroundings, including yourself, unpleasant. Experience. If washing is delayed, dirt may not be removed or mold may occur. In addition to the sweat odor, there is a great need for deodorization of odors such as body odor and tobacco odor.

[0005] However, in the conventional technique, it is necessary to attach or coat a specific agent to the fiber cloth, which causes problems such as coloring or discoloration of the cloth or deterioration of the fiber. was there. Also,
It was difficult to eliminate the smell once soaked in the fabric, and it was not easy to completely remove bacteria and mold attached to the fabric.

Such a photocatalyst has a deodorizing property, a colorant decomposition / removal property (antifouling property), and a bactericidal property (antibacterial and antifungal).

The action of such a photocatalytic agent is as follows: the odor of sweat (main component: ammonia and isovaleric acid) is generated by moisture resident from the eccrine glands and apocrine glands under the skin due to resident bacteria around the skin.・ OH excited by photocatalyst to odor
Group (hydroxyl radical) touches the main component of sweat,
It is considered to decompose into ₂ (carbon dioxide) and H ₂ 0 (water) to deodorize. In addition, the aging odor (middle-aged odor) has the following main components:
In the case of nonenal, old man odor (middle and old age odor), main component: indole, skatole, excreta odor, main component: ammonia, other body odor: main component: acetaldehyde, methyl mercaptan, and tobacco odor: Nicotine can be decomposed with photocatalytic agents, respectively.

Processing and gravure processing can be preferably employed.

Thus, it is possible to provide women's clothing having extremely excellent functionality satisfying the durability, deodorization, antibacterial property, antifungal property and antifouling property which have never existed before. According to the present invention, since the photocatalyst is provided to the fiber cloth together with the specific binder, the functionality is not reduced even by washing. In addition, since the photocatalyst is used, the performance does not deteriorate due to a detergent during washing.

The women's clothing of the present invention uses a fiber cloth made of synthetic fibers such as polyester, polyamide and acrylic, semi-synthetic fibers such as acetate and rayon, and natural fibers such as wool, silk, cotton and hemp.

The amount of the inert titanium oxide added is preferably from 0.3 to 5% by weight, more preferably from 0.5 to 4% by weight, based on the weight of the fiber. . If it is less than 0.3% by weight, the polyester fiber is easily decomposed by the photocatalyst, and the photocatalytic function and the physical properties as a fiber structure cannot be maintained with high durability. On the other hand, if it exceeds 5% by weight, no satisfactory yarn-forming property or yarn physical property can be obtained.

The cross-sectional shape of the fiber used in the present invention is not particularly limited, and any of a round cross section and an irregular cross section can be used. In the case of a modified cross section, the surface area of the fiber is increased, and the functionality imparted to the fiber is higher than that of the round cross section, which is preferable. Since spinning becomes difficult when the degree of irregularity is high, the irregular section modulus is preferably 1.2 to 2, preferably 1.3 to 1.8.
Is more preferable. Here, the modified section modulus is the ratio of the outer peripheral length of the modified section to the outer peripheral length of a perfect circle having the same cross-sectional area as the modified section, and specifically,
It is a value obtained by dividing the outer circumference of the irregular-shaped fiber by the outer circumference of the perfectly circular-shaped fiber. It is considered that the larger the value is, the larger the surface area per weight of the yarn is, and accordingly, the area of the photocatalyst layer is also increased, and the functionality given to the fiber is considered to be improved.

Further, a nonwoven fabric can also be applied.

The fineness of the yarn of the women's outer garment is preferably greater than 200 dtex and not more than 1000 dtex. It should be noted that those having a density of 200 decitex or less are not preferable because the outer garment becomes thin. Further, those exceeding 1000 decitex become too heavy and are not preferable as the outer garment. As the structure, various changed structures such as a plain weave, a twill fabric and a dobby weave are preferably used.

The women's clothing includes all fabrics, such as fabrics and accompanying belts such as laces, strings, threads, and the like.
