2. Description of the Related Art In recent years, awareness of health and hygiene has been increasing in accordance with the improvement of the standard of living of the people. Has been put to practical use.

On the other hand, cloth products, especially windproof and waterproof clothing for outdoor use such as jackets, coats, blousons, skis, snowboards, and trekking, have a high need for deodorant, antibacterial and antifouling properties. For example, if you spend time in a pachinko parlor, an amusement center such as a game center, a smoking vehicle in a train, or a rest room in a ski resort, etc. Even if you sweat, etc., the body odor and sweat odor soak into the clothing as well, especially in windproof waterproof clothing, sweat easily stays inside the clothing, and it is often difficult to wash,
The stench that soaks into these clothes does not go away easily and is often unpleasant. In addition, in outdoor use, there are particularly many opportunities to be exposed to rain and mud. If these are left as they are attached, dirt and mold will be generated, which is not preferable in terms of hygiene.

[0004] On the other hand, in the prior art, at present, only a technique for spraying a deodorant spray is provided. In this way, the smell disappears temporarily, but the smell that soaks in the cloth will still occur and will not lead to a fundamental solution. In other words, it is extremely difficult to deodorize the odor that has soaked into the cloth with the conventional technology.

[0005]

DISCLOSURE OF THE INVENTION The present invention is excellent in that it has no discoloration or deterioration during use, has a long-lasting odor preventing and deodorizing effect, and simultaneously satisfies antibacterial, antifungal and antifouling properties. It is intended to provide a windproof and waterproof garment having the above functions.

[0006]

The inert titanium oxide is light of a specific wavelength, particularly preferably titanium oxide which is inactive without being excited by ultraviolet rays, preferably titanium oxide used as a matting agent in the production of polyester synthetic fibers. used. By adding such inert titanium oxide, the inorganic property is enhanced by adding inorganic titanium oxide to 100% organic polyester fiber, and the redox effect of the photocatalyst present on the fiber surface on the polyester fiber is increased. It is believed that the effect of the action is reduced. Such inert titanium oxide can be added at the time of polymerization of the polyester fiber, and has an average particle diameter of preferably 0.1 to
The thickness is preferably 0.7 μm, more preferably 0.2 to 0.4 μm.

The amount of the inert titanium oxide is preferably 0.3 to 5% by weight, more preferably 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, nylon 6 and nylon 66 are preferably used as polyamide fibers.

The fiber form of the fiber is not particularly limited, but spun yarn and filament yarn are preferably used. A crimped yarn (a wooly yarn, a buleria yarn, a composite processed yarn, or the like) is preferably used because a filament yarn can impart stretchability.

The fiber form of the fiber is not particularly limited, but spun yarn and filament yarn are preferably used. As the filament yarn, a crimped yarn (a wooly yarn, a buleria yarn, a composite processed yarn, or the like) is preferably used because stretchability can be imparted. In addition, such synthetic fibers may include semi-synthetic fibers such as acetate and rayon, and natural fibers such as wool, silk, cotton, and hemp.

The fabric structure of the windproof and waterproof clothing includes a woven fabric,
The form of a knitted fabric is preferable, and a nonwoven fabric can also be applied. The yarn fineness is preferably from 20 to 1000 decitex. By setting it to 20 dtex or more, it is possible to obtain physical properties as clothing such as tearing and tensile strength. In addition, by setting it to 1000 decitex or less,

As such a high-density woven fabric, for example, a multifilament having a single-fiber fineness of 1.3 dtex or less and having a woven fabric cover factor of 1500 or more is preferable. Here, the cover factor is represented by the following relationship. Cover factor = (total fineness of warp yarn x 1.11) ^1/2
× warp yarn density + (total fineness of weft yarn × 1.11) ^1/2 × weft yarn density (the unit of fineness is decitex.) As a more specific example, a polyethylene terephthalate yarn of 67 decitex 72 filaments is used for warp and weft. , Density: 180 / 2.54cm, Horizontal: 94
A plain woven fabric having a pitch of 2.54 cm is preferable as a high-density woven fabric for moisture-permeable waterproof clothing. In addition, it is preferable to apply a so-called sire process to perform a heat calendering process on such a high-density woven fabric in order to make the woven structure more dense.

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

For example, the smell of sweat can be caused by eccrine glands under the skin,
The water from the apocrine glands is mixed with the resident bacteria around the skin, and it is mainly composed of ammonia and isovaleric acid. It is considered that the main component is touched and decomposed into CO2 (carbon dioxide) and H20 (water) to deodorize. In addition, the so-called aging odor (middle-aged and old-aged odor) contains the main component nonenal, the old-man odor (middle-aged and old-fashioned odor) contains the main component indole and skatole, the excrement odor contains the main component ammonia, and the other body odor contains the main component acetaldehyde. Methyl mercaptan and nicotine, the main component in tobacco odor, can be similarly decomposed with a photocatalyst.

In the present invention, among the photocatalysts, it is preferable to use a composite oxide of titanium and silicon.
As such a composite oxide, a catalyst produced by the method described in Japanese Patent Publication No. 5-55184 may be used. In general,

Is preferable.

If the particle size of the photocatalyst is too large or the specific surface area is too small, the decomposition rate of organic substances, especially bacteria, tends to decrease. In addition, the deodorizing reaction is considered to go through a process in which malodorous components are adsorbed on the catalyst and then undergo ultraviolet oxidative decomposition, and the quality of adsorption of malodorous components is considered to have a large effect on deodorizing efficiency. Is preferably from 100 to 300 m ² / g, and those having a primary particle diameter of 20 nm or less are preferably used. The amount of the photocatalyst attached to the fiber structure is
0.05 to 30% by weight is preferable, and in a method of applying to print or gravure fabric, more preferably 0.0 to 30% by weight.

In the present invention, at least one kind of binder selected from an alkyl silicate resin, a silicone resin and a fluorine resin is used for adhering a photocatalyst comprising a composite oxide of titanium and silicon to the fiber surface. It is preferable to use The difference between such a silicone resin and a fluorine resin and an acrylic resin, a urethane resin, an epoxy resin, etc., which are often used, is that they hardly contain hydrocarbon groups which are easily decomposed by the action of heat or chemicals, and the silicone resin is The Si-O bond and the fluorine-based resin are mainly composed of the F-C bond, and are such that a small amount of a methyl group or a phenyl phase is contained as a hydrocarbon in a terminal group or a side chain. That is, due to the presence of such a binder, decomposition attributed to oxidation of the resin by the photocatalyst,
Coloring and generation of odor can be prevented.

The amount of the resin adhering to the fiber is preferably 0.05 to 100% by weight in the coating method and 0.05 to 30% by weight in the impregnation method, from the viewpoint of holding the photocatalyst and feeling.

As the fluorine-based resin, vinyl ether and / or vinyl ester and a fluoroolefin polymerizable compound are preferably used because they have very excellent properties. For example, polyvinyl fluoride, polytetrafluoroethylene, tetrafluoroethylene-perfluoroalkylvinylester, vinylester-fluoroolefin, and the like are preferably used because they are less decomposed and deteriorated.
The amount of the resin adhered to the fibers is preferably 0.05 to 100% by weight in the coating method and 0.05 to 30% by weight in the impregnation method from the viewpoints of holding the photocatalyst and feeling.

Further, it is preferable to further add zeolite to such a binder since there is an effect of further improving the antibacterial performance. That is, it has the effect of improving the adsorption power of odorous components and increasing the ratio of inorganic components in the structure, and suppressing the decomposition of the structure and the binder by the photocatalyst. The use of a zeolite carrying a noble metal such as gold, platinum, silver, or palladium, preferably in a range of 0.01 to 5% by weight, exhibits a function of further improving the antibacterial effect. The amount of such zeolite adhering to the fiber is preferably 0.01 to 10% by weight in the coating method, and preferably 0.01 to 5% by weight in the impregnation method, from the viewpoint of the manifestation of the effect and the feeling.

Further, by further adding a coupling agent such as a silane coupling agent to the above-mentioned binder, the adhesive strength between an inorganic substance and an organic substance can be improved.

The amount of the coupling agent attached to the fiber is preferably 0.01 to 30% by weight in the coating method, and preferably 0.01 to 10% by weight in the impregnation method, from the viewpoint of the manifestation of the effect and the feeling. .

As a method for adhering a photocatalyst agent and a binder to the fiber surface, for example, a so-called impregnation method in which a processing liquid is impregnated, squeezed with a mangle roll, and subjected to a dry-cure process, or a method such as printing or gravure is used. A coating method can be preferably employed. In the impregnation method, the conditions of temperature and time for dry-curing are as follows: dry: 110 to 135 ° C. × 1 to 3 minutes;
190 ° C. × 1 to 3 minutes is preferably applied. In the coating method, the coating process such as printing and gravure is performed by adjusting the working liquid to an appropriate viscosity with a glue, and applying with a knife coater, a gravure roll coater, printing, etc.
So-called ordinary print processing and gravure processing, which are fixed at a temperature of 200 ° C. × 5 to 30 minutes, can be preferably applied.

Further, it is also preferable to apply a coating of an acrylic resin or a polyurethane resin to impart moisture permeability and waterproofness. For the purpose of the coating resin, for example, a wet method of solidifying the resin material in water or a dry method of coating using various doctors such as rolls, knives and commas can be appropriately applied depending on the purpose of the moisture permeability. In addition, a lamination method in which a resin film is previously coated on a film or release paper and then bonded to a fabric surface together with a binder is also preferably used. Of course, a film combining a coating and a laminate can also be suitably applied.

Furthermore, it is also preferable to apply a general water-repellent treatment by applying a water-repellent agent before or after coating or laminating, since it is possible to prevent the cloth from being wetted with water and to improve the waterproofness. As the water repellent, a fluorine water repellent, a mixture of a fluorine water repellent and a silicone water repellent, or the like can be preferably applied.

When there is no problem in the compatibility between the photocatalyst processing agent and the water repellent, coating or lamination may be performed after the photocatalyst processing and the water repellency processing are simultaneously applied.

Thus, the satisfies the durable anti-odor, deodorant, antibacterial, antifungal and antifouling properties which have never existed before.
In addition, it is possible to provide a windproof waterproof garment having excellent windproof waterproof properties.
