[0039] In the deodorizing material of the present invention, fullerenes as the deodorizing active ingredient as described above can be contained in the base material or supported on the base material. The substrate in this case may be a liquid or a solid. In the case of a solid, the shape and structure may vary, and for example, it may be a granular material, a fibrous material, a woven fabric, a nonwoven fabric, a film, a sheet, and various other three-dimensional molded products. Regarding the inclusion of these solids in the base material, it is considered that they are integrated by shaping through, for example, mixing with a base component or adhesion. This is due to granulation after kneading, extrusion molding, cast molding, injection molding, fiberization, and the like.

[0040] One solid substrate can be supported by various methods. For example, a porous base material, such as a woven fabric base material having microscopic voids, is immersed in a dispersion of a fullerene solution or a method of adhering and supporting fullerenes in a microporous space, Adhesion and loading by the method of coating, by flowing down or by various other means are considered.

[0048] Further, the deodorizing material of the present invention can be used by, for example, being contained in a porous film or sheet and supported on the porous film or sheet, and these film and sheet are attached to furniture or indoor interior materials. It can be used by hesitation. It may be contained or carried in a filter for air conditioning or ventilation equipment.

[0049] By containing or supporting fibers or fabrics, for example, underwear and linens, odors such as nonenal, acetoaldehyde, otatenal, hexenal, palmitoleic acid, etc., which are the main components of aging odor and odor Can be selectively deodorized, and in socks, body odors such as ammonia, indole, skatole, and mercaptan can be deodorized by deodorizing foot odors such as isovaleric acid.

[0050] In the following, an example will be shown and described in more detail. Of course, the invention is not limited by the following examples.

Example

The sample bottle into which nonenal was injected was kept in a dryer at 80 ° C for 30 minutes, and then gas was collected and measured by gas chromatography. The following samples were used.

[0052] A1: Nonenal alone A2: lOmg fullerene (C6

To 0, C70 of 10wt ^_0/0, C80 force S mixed)

A3: lOmg of activated carbon was added to the sample injection bottle. In each case, the results shown in Fig. 1 were obtained in the gas chromatograph. From this Fig. 1, it can be seen that fullerene has a deodorizing effect on nonenal gas that far exceeds activated carbon. <Example 2>

The sample bottle infused with nonenal was kept in a dryer at 80 ° C for 30 minutes, then the gas was collected and the next sample was prepared at 37 ° C, which is close to human body temperature.

[0053] A1: Nonenal alone

A2: lOmg fullerene in sample bottle injected with Nonenal (C60 mixed with 10wt% C70 and C80)

A3: lOmg of activated carbon was added to the sample injection bottle.

The above three samples were left to stand for 2 hours at 80% humidity in the nearヽ37 ° C in human skin environment gas portion of the original body ^10-4, 10 ^"5, 10 ⁶ times 37 ° in the same conditions Dilute with 80% humidity air at C and donate to sensory test.

[0054] As a result of performing 30 panelists in the sensory test and evaluating them according to the following criteria, it was found that fullerene surpassed activated carbon:

6-level odor intensity display method:

0: 10- ⁶ times the odorless A2

1: Odor barely perceivable (odor threshold concentration) A2 of 10 ^4, 10 ⁵ fold dilutions

2: What you per cent, are either seen in weak and to, 10_ ^6-fold dilution of (recognition threshold concentration) A3

3: Easily perceived scent A3 10 to ⁵ times diluted

4: strong 10- ^6-fold dilution of smell A1, 10- ^4-fold dilution of the A3

5: Strong smell A1 10 10- ⁵ times diluted

In Example 2, instead of fullerene, PVP (polybulurpyrrolidone) composite thiofullerene was used. As a result, almost the same result as in Example 2 was obtained.

A woven fabric for underwear of 80% cotton and 20% polyester is prepared, and this is immersed in an ethanol solution in which the same fullerene as in Example 1 is dissolved and dispersed, and then dried to obtain fullerene. It was carried on a woven fabric.

[0055] Under the above procedure, an underwear having a high deodorizing effect was produced.
