目的で、その需要は増大しつつある。2. Description of the Related Art In recent years, by adding a specific function to a fiber, the value of the fiber has been increased. In particular, a fiber having an ultraviolet shielding function and an antibacterial and deodorizing function has been proposed. The amount of ultraviolet rays that reach the ground increases year by year due to the increase in ozone holes,
The adverse effect on the human body is pointed out, and the demand for protecting the skin from ultraviolet rays is increasing.

Or it causes yellowing, antibacterial properties help extend the life of clothing, and various fungi also have the effect of transforming secretions generated from the human body into components that emit foul odors. It is also recognized that the deodorant property suppresses the growth of fungi and contributes to the deodorization of clothing. For this reason, antibacterial and deodorant fibers are meeting the recent trend of cleanliness, and the market is expanding.

る。[0004] The production of such ultraviolet shielding fibers and antibacterial and deodorant fibers will be described. First, when producing an ultraviolet shielding fiber, an organic ultraviolet absorbent such as benzophenone or benzotriazole is added to the fiber,
Addition of iO 2 fine particles has been performed. The production of fibers having an organic UV absorber involves melting the resin constituting the fibers, dissolving the organic UV absorber uniformly in the resin, or dispersing the TiO 2 fine particles, and then spinning. . When producing antibacterial and deodorant fibers, a method of kneading an organic antibacterial agent or kneading a silver ion-based or copper ion-based inorganic antibacterial agent can be considered.

場合がある。However, when an organic ultraviolet absorber is used for the ultraviolet shielding fiber, the melting temperature of the resin is high, for example, 200 to 300 ° C. for polyester fiber or nylon fiber. In most cases, the temperature exceeds the heat resistance temperature of the system-based UV absorber, and the organic-based UV absorber sublimates and volatilizes, or decomposes and disappears. When TiO 2 fine particles are added to the ultraviolet shielding fiber, TiO 2 has a refractive index of about 2.6 (rutile type).
Since the refractive index of the ZnO particles is larger than the refractive index (about 1.9), when light is incident on the fiber in which the TiO 2 particles are kneaded, the ratio of the scattered light increases, and a matting effect appears.
When dyeing fibers mixed with TiO 2 fine particles, they tend to have a dull color tone, which may be inconvenient for product design.

However, most of the organic antibacterial agents disappear by thermal decomposition or sublimation. And antibacterial
When kneading silver or copper ion-based inorganic antibacterial agents into deodorant fibers, silver ions or copper ions are liable to discolor, such as becoming dark brown by oxidation, and are difficult to use for white or light-colored fibers. There is.

A method has been proposed in which O fine particles are kneaded into artificial fibers to produce fibers having both functions of blocking ultraviolet rays and having antibacterial and deodorant properties (JP-A-5-156510). That is, Zn
Since the O fine particles have excellent ultraviolet shielding properties and antibacterial and deodorant properties, the kneading of a single material, such as ZnO fine particles, into fibers can provide these composite functions at once. Further, since the ZnO fine particles are inorganic crystals and have a melting point of 1980 ° C. (under pressure), they have high heat resistance and have no problem at the melting temperature of the fiber resin. In particular, when the temperature is lower than about 300 ° C., there is no coloring due to oxidation or the like, and there is no fear of discoloration of the fiber into which the ZnO fine particles are kneaded.

Since it is much lower than that of the above, light is less scattered. Further, when the particle diameter is 0.1 μm or less, visible light is not absorbed and transmitted, so that the fiber kneaded with ZnO fine particles is very Transparency increases. And
The use of ZnO is also recognized in the Japanese Pharmacopoeia, etc., and is highly safe in combination with being an inorganic crystal. Even if it is in contact with the skin for a long period of time, it has almost no adverse effect.

判明した。However, when ZnO fine particles are kneaded into artificial fibers such as polyester and nylon, the ZnO fine particles tend to re-aggregate in the molten fiber resin, and as a result, the ZnO fine particles are coarse in the fiber resin. Become This Z
When the nO fine particles are coarsened, the nozzle for drawing the molten resin or the mesh installed on the back of the nozzle is easily clogged during the subsequent spinning, and it is difficult to perform a stable spinning operation for a long period of time. become. Also, Z
When the nO fine particles are coarsened, the specific surface area of the ZnO fine particles is reduced, and the ultraviolet shielding property and the antibacterial and deodorant properties are reduced. Furthermore, ZnO fine particles have a photocatalytic action,
It was found that the fiber kneaded with the ZnO fine particles was inferior in the light resistance to the fiber into which the ZnO fine particles were not added, because it promoted the deterioration of the surrounding fiber resin in direct contact with the O fine particles.

の劣化を抑制することが可能になった。Hereinafter, the present invention will be described in detail. When the surface of the ZnO fine particles was coated with a silicon compound in order to suppress the tendency of the ZnO fine particles to re-aggregate and suppress the photocatalytic activity, it was found that the ZnO fine particles had a remarkable improvement effect. That is, when the surface of the ZnO fine particles is covered with the silicon compound, the affinity between the ZnO fine particles can be suppressed, and the tendency of coarsening due to aggregation can be suppressed. Thus, it was possible to form a barrier layer, thereby suppressing deterioration of the fiber resin due to the photocatalytic activity of the ZnO fine particles.

When the addition ratio to the ZnO fine particles is 0.1% by weight or less, it is not sufficient to suppress the re-aggregation property and photocatalytic activity of the ZnO fine particles. Further, when the addition ratio to ZnO fine particles is 30% by weight or more, even if the addition amount is further increased, the suppression effect is not enhanced, but rather the antibacterial property of ZnO fine particles is inhibited, which is an opposite effect.

より製造することができる。The reason why the particle diameter of the ZnO fine particles is set to 0.1 μm or less is that if the particle diameter exceeds 0.1 μm, sufficient ultraviolet ray shielding properties, antibacterial and deodorant properties cannot be obtained, and when melt spinning, This is because clogging of a nozzle, a mesh or the like causes a serious problem in spinnability. Further, when the particle diameter of the ZnO fine particles exceeds 0.1 μm, it is not preferable to produce a low-denier fine thread because the physical strength thereof is reduced.

On the other hand, if the addition amount exceeds 50% by weight, the ultraviolet ray shielding properties and the antibacterial and deodorant properties cannot be further improved. If the amount of the ZnO fine particles exceeds 50% by weight, the physical strength and the like of the fiber are significantly reduced.

とがわかる。As is clear from Table 1, by subjecting the ZnO fine particles to various silicon treatments, the spinnability at the time of spinning the polyester filament can be greatly improved, the dispersibility of the ZnO fine particles can be improved, and reagglomeration can be prevented. We can see that we can do it. Also, as shown in Table 2, when the untreated ZnO fine particles are kneaded, the light resistance of the polyester is reduced mainly due to the photocatalytic activity of the ZnO fine particles. It can be seen that the properties are improved.
