Abstract

PURPOSE: To prevent bacteria and fungi which become an odor source from propagating not only removing odor by a method wherein univalent copper and ascorbic acid are carried by a nonwoven fabric of an activated carbon fiber or a ceramic fiber, and covered by a net. CONSTITUTION: This insole is constituted of a cuprous oxide and ascorbic acid impregnated activated carbon fiber nonwoven fabric 1, a net 2 made of a synthetic resin, and a heat-seal part 3. For such an insole, cuprous oxide and ascorbic acid which are suspended with water by a rate of 20:1, are impregnated and bonded to the activated carbon fiber nonwoven fabric. This nonwoven fabric is wrapped with the net made of a synthetic resin under a sandwich state, and after cutting them adjusting to a foot shape, the cut end is heat-sealed to manufacture the insole. The insole prevents bacteria from propagating, prevent odor from generating, and also removes a generated odor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an insole (In8ole), that is, an insole for a shoe.

[Prior Art] Conventionally, there have been insoles and spray deodorizers using activated carbon to remove odor from shoes, but none of them are satisfactory in terms of effectiveness and longevity.

[Problems to be solved by the invention] The source of odor in shoes is sweat and secretions from the human body (feet) that are decomposed by microorganisms such as bacteria, but activated carbon, etc. used conventionally, does not emit odor. It does not remove the odor by adsorption, but it does not stop the source of the odor.

[Purpose of the invention]

The present invention aims to provide an insole that can prevent the growth of microorganisms and fungi that cause odors, rather than simply removing odors.

[Means for Solving the Problems] The present invention is an insole characterized in that monovalent copper and ascorbic acid are supported on a nonwoven fabric of activated carbon fibers or ceramic fibers, and the insole is covered with a net.

[Effect]

Monovalent steel has a strong bactericidal effect, and by adding ascorbic acid to it, the monovalent state of copper can be maintained. The bactericidal effect of monovalent copper is thought to be due to hydroxyl radicals (・OR) generated during the oxidation process, but hydroxyl radicals also have the effect of decomposing and deodorizing odor components, and are also effective in treating athlete's foot. be.

〔Example〕

Hereinafter, one embodiment 911 of the present invention will be described with reference to FIG. FIG. 1 shows a sectional view of the insole, in which 1 is an activated carbon fiber nonwoven fabric impregnated with cuprous oxide and ascorbic acid, 2 is a synthetic resin net, and 3 is a heat-sealed portion. This insole is made by impregnating activated carbon fiber nonwoven fabric with oxidized fabric-copper toascorbic acid (ZO:1) suspended in water.
It is made by wrapping it in a sandwich shape with a synthetic resin net, cutting it to fit the shape of the foot, and then heat-sealing the cut ends.

In order to evaluate the effectiveness of this insole, we measured the change in removal rate over time using methyl mercaptan as a simulated odor. The results are shown in FIG. In FIG. 2, M is a graph of the actual insole, and B is a graph of a comparative insole made of an activated carbon fiber nonwoven fabric impregnated with only cuprous oxide. Methyl mercaptan is more powerful than human sweat, so this test can be considered an accelerated test of the actual insole usage environment.

As can be seen from Figure 2, compared to the comparative product, the methyl mercaptan removal rate is generally superior to that of the same product, and the removal rate decreases slowly, providing a powerful and long-lasting deodorizing effect. .

When I used the same product, I rarely experienced it during the period when I was prone to sweating, but it did not cause any odor and kept the office dry and comfortable.

Note that even if a ceramic fiber nonwoven fabric such as zeolite is used in place of the activated carbon fiber nonwoven fabric in the above examples,
The same effect as above was obtained.

〔Effect of the invention〕

As described above, the inole according to the present invention can prevent the growth of fungi, prevent the generation of odor, and also remove the odor generated. It also has antibacterial properties against the fungi that cause athlete's foot, such as M. cilitico, and is effective in treating athlete's foot.
