Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fibrous structure having excellent functions such as durable anti-odor, deodorant, anti-mold, anti-fouling and anti-bacterial properties which have never existed before. .

[0002] More specifically, the present invention relates to a textile structure such as sports clothing, innerwear, work clothing, lining material, and curtain.

[0003]

2. Description of the Related Art In recent years, awareness of health and hygiene in clothing and living materials has been increasing along with the improvement of living standards. In various related fields, deodorant, antibacterial (antibacterial), antifungal and antifouling techniques have been developed. Processed products and technologies are required.

[0004] In particular, in the field of apparel, especially sportswear, innerwear, etc., there is a high need for such deodorant, antibacterial and antifouling properties, but processing techniques that provide excellent deodorant, antibacterial and antifouling effects are still being developed. This is not the situation.

[0005] For example, if you sweat after playing sports such as tennis or golf, you often experience the smell of sweat, and this smell not only affects the smell of the person but also the surrounding people. May have an effect. Also, after schoolchildren and students exercise, stuffing shirts and pants in bags and leaving them as they are will not remove the smell of sweat even when washed later, which is not good for smell and hygiene .
There is a similar problem with innerwear.

On the other hand, if you smoke after playing sports,
It is often experienced that tobacco smell is adsorbed on sports clothes and that the smell is unpleasant.

[0007] Such a problem also exists in other living materials.

[0008] That is, for example, to remove the smell of clothes after eating meals such as grilled meat, there is a spray injection, etc., but it is temporary, and the lining material such as a deodorant clothes cover is extremely low. Although there are high needs, they have not been realized yet. Furthermore, curtains are required to have a deodorizing effect on the smell of cigarettes, the odor of the elderly and nursing odors in hospitals and nursing homes, but they have little effect and are often washed at high temperatures. Do
It could not withstand the so-called industrial launderability, and did not reach a complete solution. As described above, none of the fabrics has satisfactory odor prevention and deodorant properties.

On the other hand, in recent years, infections in hospitals due to methicillin-resistant Staphylococcus aureus (hereinafter referred to as "MRSA") have become a problem. In addition, many patients have significantly reduced resistance, other than bacteria such as MRSA,
Even mildew having a relatively low effect on the human body has a problem of hospital infection, and it is necessary to impart high antibacterial properties, that is, bacteriostatic properties and fungicidal properties.

[0010] In order to deal with such a problem, a method of imparting a high deodorizing property includes photocatalytic processing. However, the titanium oxide photocatalyst used in conventional processing requires a binder resin to be fixed to the fiber, and in the conventionally used acrylic or urethane binder resin, the organic hydrocarbon constituting the resin is composed of the titanium oxide photocatalyst. It is decomposed by strong oxidative decomposition power, and is colored or discolored, and does not exhibit a sufficient deodorizing effect. In addition, antibacterial and antifungal properties are poor.

On the other hand, in the method of imparting antibacterial properties, for the antibacterial treatment of the fiber, a method of kneading an inorganic antibacterial agent such as silver, copper or zinc at the spinning stage of the synthetic fiber and a method of quaternary ammonium salt or the like are used. Post-processing methods in which an organic antibacterial agent is applied by spraying or padding have been employed.

The former case is excellent in washing durability, but cannot be processed into products such as cloth. That is,
Because the antibacterial agent precipitates as crystals on the spinneret during the spinning stage,
Thread breakage, fusion, etc. occurred, and the amount of the antibacterial agent had to be reduced to form a fabric. Further, since the antibacterial agent is uniformly dispersed in the yarn, it needs to be kneaded in a large amount, and there is a problem that the cost is high.

Further, in Japanese Patent Application Laid-Open No. 12-199555, an antibacterial agent is put into the interior of a fiber, an intermediate layer of peroxide particles or zeolite is deposited on the surface thereof, and a photocatalyst is further adhered on the surface to provide a deodorant property. Processing methods having both antibacterial properties have been proposed.

However, in this method, since such an intermediate layer is formed, the antibacterial agent is confined in the center of the fiber structure (fabric), and the antibacterial effect is another step. That is, since the concentration of the antibacterial agent on the surface of the fabric is low, the growth of various bacteria (resident bacteria) on the skin cannot be suppressed, and the effect is reduced. By the way, when the concentration of the antibacterial agent is increased, the texture is too hard to be practical as a garment, and at the same time, the antibacterial agent, the auxiliary agent for forming the intermediate layer and the photocatalyst are simultaneously processed (the same bath treatment). Doing so has a problem that a complex (aggregate precipitation) with the intermediate layer or the photocatalyst is generated and processing unevenness occurs.

[0015] Furthermore, the processing step requires three steps of providing an antimicrobial agent, providing an intermediate layer, and providing a photocatalyst. This is a long process, resulting in poor production efficiency and high cost.

[0016]

As described above, according to the prior art, it has both a high deodorizing effect of imparting a deodorant effect of smell permeating a fiber cloth and an atmosphere and a bacteriostatic effect, and can withstand industrial washing. It was impossible to obtain a product that was durable and could be easily and efficiently produced.

The present invention has been made in view of the problems of the prior art and the demands of those who wear and use conventional clothing and living materials.
At the time of use, it has an extremely long lasting deodorizing effect that could not be achieved by the conventional method, and at the same time, it has satisfactory antibacterial properties, antifungal properties, and antifouling properties, and can be efficiently produced. Is to be provided.

The fiber structure 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, The photocatalytic agent and the bacteriostatic agent are simultaneously and substantially uniformly attached.

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 fiber structure of the present invention, attention is paid to the fact that such a photocatalyst has deodorizing properties and colored substance decomposition / removal properties (antifouling properties), and this is applied to clothing and living materials to make the best use. It is a thing.

The action of the 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

The particle diameter of the 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.

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

Incidentally, it is preferable to further add a coupling agent to the above-mentioned binder since the adhesive strength between the inorganic substance and the organic substance can be improved. This gives the fiber,
A chemical bond acts between the binder and the photocatalyst, leading to an improvement in washing durability. The amount of the coupling agent to be attached to the fiber is preferably 0.01 to 0.01% by the coating method.
In the impregnation method, the content is preferably controlled in the range of 0.01 to 10% by weight from the viewpoint of feeling. As such a coupling agent, for example, a silane coupling agent can be preferably used.
