BEST MODE FOR CARRYING OUT THE INVENTION First, the present inventor individually measured the antibacterial rate, deodorizing rate and far-infrared emissivity of a single-component ceramic, respectively, and found that it was excellent in antibacterial rate or deodorizing rate and far-infrared emissivity. While extracting the thing, each of the ceramics is adopted as one of the base material, the mixture material and the auxiliary material and mixed and stirred at a constant ratio, and then calcined to have antibacterial properties and deodorizing properties, By producing a composite ceramic having far-infrared radiation characteristics, and also having fungicidal and insect repellent properties, and adding the mixed ceramic to viscose during the rayon production process, the antibacterial material of the present invention is obtained.

However, the measured values shown in Tables 1 and 2 were obtained.

From the above results, the present inventor has a high antibacterial activity against both Escherichia coli and staphylococci, a high deodorizing activity against ammonia and hydrogen sulfide, and a comparative emissivity. High serpentine is used as the base material of the composite ceramics used in the present invention, and the serpentine base material is mixed with silica or zinc oxide as a mixture, and zinc oxide (mixed material) Excluding zinc oxide), tourmaline, zeolite, and calcium oxide are added to and mixed with the substrate to provide antibacterial, deodorant, antifungal, and insect repellent properties.

The single-component ceramics constituting the composite ceramics used in the present invention, such as serpentine, silica, zinc oxide, tourmaline, zeolite, and calcium oxide, are mixed at the preferable mixing ratios shown in Table 3, respectively. Table 4 shows the results of measuring the far-infrared emissivity, mold resistance, repellency, antibacterial rate, and deodorization rate of the manufactured composite ceramics, which show insect repellency against sanitary pests such as fleas and ticks. In addition,
Symbols 1 to 4 in Table 4 correspond to symbols 1 to 4 in Table 3.

[0013]

[Table 3]

[0014]

[Table 4]

From the results shown in Table 4 above, all the composite ceramics showed high values in the antibacterial and deodorizing rates due to the synergistic effect of the ceramics of each single component constituting the composite ceramics. It was also found to be excellent in far-infrared emissivity, mold resistance and repellency showing insect repellency to sanitary pests.

Hereinafter, a method for producing a composite ceramic having antibacterial properties, deodorizing properties, fungicidal properties and insect repellency and far-infrared radiation characteristics employed in the present invention will be described in more detail. The particle diameter of each ceramic of each single component constituting the composite ceramics must be fine powder of 5 μm or less, and when these ceramics are mixed, the specific gravity, moisture, humidity, etc. The characteristics of the ceramics are different from each other, and each of the ceramics, which are the raw materials, is a fine powder having a particle size of 5 μm or less. Therefore, it is very difficult to uniformly mix the ceramics because the agglomeration acts easily.

The inventor of the present invention introduced the base material, the mixed material and the auxiliary material into the mixer at predetermined ratios according to the mixing ratios shown in Table 3 and mixed and stirred the mixture. By throwing in and pulverizing, and further, repeating the process of throwing the ground into the mixer again, mixing and stirring, and then throwing into the mill again and grinding for about 30 minutes. Thus, it was possible to produce a composite ceramic in which the base material, the mixed material, and the auxiliary material were uniformly mixed.

In order to stabilize the chemical properties of the uniformly mixed composite ceramics, the composite ceramics are fired by a firing machine at a calcining temperature of 200 to 500 ° C. to obtain antibacterial properties, deodorization properties, and antifungal properties. It is a composite ceramic having properties and insect repellency and having far-infrared radiation characteristics.

The hydrogen ion concentration of each of the ceramics as the material of the composite ceramics has an alkaline property as shown in Table 5. Also, the composite ceramics composed of each of the above ceramics has an alkaline property as shown in Table 6. Symbols 1 to 4 in Table 6 correspond to symbols 1 to 4 in Table 3.

[0020]

[Table 5]

[0021]

[Table 6]

The hydrogen ion concentration of the composite ceramics employed in the present invention in which each ceramic having the hydrogen ion concentration shown in Table 5 is composited is 200 ° C. to 500 ° C. as described above.
Since it was baked at ℃, it has very stable and alkaline properties as shown in Table 6. Further, these composite ceramics are crystallized by calcination to become composite ceramics having a function of generating electric field energy (cation). The reason why the composite ceramic exhibits an alkaline property is that impurities are gasified during the sintering process, so that the composite ceramic becomes more alkaline than a single component ceramic.

From Tables 4 to 6, it has been proved that the composite ceramics obtained by the production method is a composite ceramics which generates cations by far-infrared radiation and becomes hydrogen ions in an alkaline region. Further, the deodorizing mechanism has a property of decomposing action, and as a result, the composite ceramics obtained by the manufacturing method has both antibacterial properties and deodorizing actions in addition to having far-infrared radiation properties. I understand.

That is, the antibacterial mechanism of the composite ceramics is that the surface layer (wall) of general living bacteria such as Escherichia coli and staphylococci is an anion, and thus the neutral region (pH)
7.0 to 7.5), but the cations are generated as the largest characteristic of the composite ceramics obtained by the above-mentioned production method. At the same time, the surface layer (wall) is destroyed by the cations of the composite ceramics, and at the same time, the bacterial protein is denatured and becomes difficult to breathe and is killed.

The deodorizing mechanism of the composite ceramics against hydrogen sulfide, ammonia and the like is not a general action such as physical adsorption or chemical adsorption, but is not saturated due to a decomposition action. Has semi-permanent deodorizing power. The composite ceramics has no toxicity.

Further, cations generated by far-infrared radiation of the composite ceramics inhibit the generation or proliferation of mold, thereby fulfilling a fungicidal function, and the cations provide insect repellency against sanitary pests such as fleas and mites. It has a repellent effect showing

It is preferable that the particle size of the particles of the composite ceramic used as the material of the present invention is sufficiently small so as not to hinder the production of rayon. In the case of relatively thick rayon, those having a particle size of about 5 to 15 μm can be used, but usually those having a particle size of about 0.1 to 5 μm, particularly about 0.2 to 1.5 μm are suitable. Conversely, when the particle size is 0.1 μm or less, aggregation of the particles is likely to occur, which is often inconvenient.

In the mixing step of mixing and mixing the composite ceramics manufactured by the above-described manufacturing method in a known rayon manufacturing process to make the quality of viscose constant and uniform, the mixing is preferably performed by the mixing machine. Is added at a ratio of 5 to 10% by weight, particularly preferably 8% by weight, and the composite ceramic is added to and mixed with viscose.

Alternatively, instead of adding and mixing in the mixing step of the composite ceramics, after the mixing step and the filtration step,
In the defoaming step of putting the viscose into the spinning tank and defoaming, the composite ceramic is charged into the spinning tank at a ratio of preferably 5 to 10% by weight, particularly preferably 8% by weight. May be added.

Then, after adding and mixing the composite ceramics into the viscose in the above process, a composite rayon as a material of the present invention is manufactured by a known rayon manufacturing process.

With respect to the composite rayon which is the material of the present invention obtained by adding and mixing the composite ceramics shown in the symbols 1 to 4 in Table 3 obtained with the above-mentioned particularly preferable mixing ratio to cellulose, the antibacterial rate, the deodorizing rate, and the prevention When the mold resistance, the repellency, and the far-infrared emissivity were measured, the results shown in Table 7 were obtained. Symbols 1 to 4 in Table 7 correspond to symbols 1 to 4 in Table 3 and indicate a composite rayon using the composite ceramics manufactured according to the mixing ratios in Table 3.

It has a deodorization rate of 7 to 95.4%, and has a fungicide resistance of 3,
The repellent rate against sanitary pests is extremely high at 92 to 94%.
It was found that antibacterial properties, deodorizing properties, antifungal properties, insect repellent properties, and far-infrared radiation properties were imparted to general rayon.

Next, the silk fiber obtained by blending or twisting with a composite rayon having antibacterial properties, deodorizing properties, fungicidal properties and insect repellent properties, and far-infrared radiation properties, obtained by the above-mentioned production method, is already used. Generally used widely.
Since the silk fiber uses silk as a material, it is known that it has an effect of particularly excellent heat absorption / desorption properties and good heat retention properties.

It is recommended that the composite rayons 1 to 4 and the silk fibers produced according to the preferred compounding ratios are mixed or twisted and spun at the following mixing ratios. That is, 65 to 85% by weight, preferably 7% by weight of composite rayon using the composite ceramics indicated by symbol 1 in Table 3.
