Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe requiring a deodorant function, particularly an athletic shoe having a lot of sweating.

[0002]

2. Description of the Related Art As a method for imparting a deodorizing function to a textile product, a method using ascorbic acid and a divalent iron compound is described in JP-A-61-296111. It is particularly effective and has little effect on the mercaptan odor. Also, a method of processing a phthalocyanine copper compound in the same manner as dyeing a fiber is disclosed in Japanese Patent Laid-Open No. 62-
No. 6978. In addition, there is a method of processing copper sulfide into an acrylic fiber and a method of coordinating copper with a hydrolyzed acrylic fiber. However, these methods all have a serious drawback that the fibers are colored green or brown. Textile products are fashion products that are colorfully fashioned. Fibers colored green or dark brown cannot be dyed lightly.

Further, a deodorant component obtained by extracting a natural camellia plant component as a deodorant is described in JP-A-56-100060. However, the deodorizing action of the natural camellia plant extract component is an inclusive action, and although the odor component is incorporated into this extract, it is inferior to the above-mentioned deodorizing effect by the catalytic action of the copper compound. Moreover, since it is a natural material, it is expensive.

[0004]

SUMMARY OF THE INVENTION The main object of the present invention is to provide an inexpensive deodorant shoe having an excellent deodorant function and washability, with which the back skin can be colored freely.

[0005]

Means for Solving the Problems As a result of studying a method for stably fixing copper ions having a deodorant function in a deodorant, the present inventors have found that a vinyl sulfonate copper salt comonomer is copolymerized. As a result, they have found that they can be stably immobilized, and studied the application to shoes, and completed the present invention.

According to the present invention, a deodorant composition in which a vinyl sulfonate copper salt comonomer is copolymerized as copper ions in an amount of 3000 ppm or more based on the solid content is 2% of the back surface of shoes.
The deodorant shoe is characterized in that 1% by weight or more is attached to the above area, or 0.3% by weight or more is attached to an area of 30% or more of the back surface of the shoe.

The vinyl sulfonic acid copper salt comonomer used in the present invention includes allyl sulfonic acid (hereinafter abbreviated as "AS") and methacryl sulfonic acid (hereinafter "MA").
It is abbreviated as "S". ), Styrene sulfonic acid (hereinafter "S
It is abbreviated as "S". ), Acrylamidomethylpropyl sulfonic acid (hereinafter abbreviated as “AMS”), and the like. These copper salts have a green or blue color, but the coloring is thinned by polymerization. Therefore, the deodorant backing using the deodorant of the present invention is colored only in a colorless or ultra-light color.

In the deodorant aqueous solution of the present invention, a vinyl sulfonate alkali metal salt comonomer can be used instead of the vinyl sulfonate copper salt comonomer. The vinyl sulfonate alkali metal salt comonomer easily undergoes a substitution reaction with copper sulfate to form a vinyl sulfonate copper salt.

The good washing resistance of the back skin treated with the deodorant in an aqueous solution is considered to be that the comonomer copper acts as a cross-linking structure.

The deodorizing action of the deodorant backing by the deodorant of the present invention depends on the amount of copper ions in the deodorant. Also,
Depends on the amount of copper ions on the back skin surface. The copper ion content may be 80 ppm or more on the surface of the back skin.

The main monomers to be copolymerized are acrylonitrile (hereinafter abbreviated as "AN"), methacrylonitrile, vinyl acetate (hereinafter abbreviated as "VA"), vinyl chloride, vinylidene chloride (hereinafter "VD"). And vinyl monomers such as styrene are used. The second monomer to be copolymerized is methyl acrylate (hereinafter abbreviated as “MA”), acrylic acid (hereinafter abbreviated as “AA”), methyl methacrylate, methacrylic acid, ethyl acrylate, butyl acrylate, Ethyl methacrylate or the like is used.

The copolymerization method is not particularly limited. Emulsion polymerization or solution polymerization that is commonly used is used. Batch polymerization or continuous polymerization may be used. The polymerization initiator is a commonly used peroxide,
Azo compounds, persulfates, etc. are used. If necessary, an auxiliary material such as a polymerization stabilizer or a coloring preventing agent may be used. In the case of solution polymerization, water or the like is used as the solvent.

The processing of the back skin with the deodorant of the present invention can be carried out in the same manner as the generally used resin processing. For example, the deodorant aqueous solution or emulsion of the present invention is dipped in the back skin by an appropriate amount by a method such as spraying, coating, or printing, and then dried and baked using a tenter dryer or the like.

In order to reduce the amount of the deodorant used, a part of the back skin can be processed by printing or the like. In particular, it is good to process it on the instep of the toe or the part of the arch where it is less susceptible to abrasion. The deodorant effect can be imparted by attaching 1% by weight or more to the area on the back side of the shoe of 1% by weight or more, or 0.3% by weight or more of the deodorant on the area of 30% or more on the back side of the shoe.

The material for the back skin used in the present invention is not particularly limited. Synthetic products such as polyethylene, polypropylene, polyester and nylon, and natural products such as cotton are used. The form of the material for the back skin is not particularly limited. For example, the material form of the back skin may be non-woven fabric, laser, woven or knitted fabric, sponge, or the like. The shape of the shoe is not particularly limited, but it is preferable to consider a structure in which a dirty odor gas can easily move.

Since the product of the present invention uses copper ions, it also exhibits antibacterial properties. When importance is attached to the antibacterial property, it may be processed into a part requiring the antibacterial property.

[0017]

The deodorant shoes of the present invention have an excellent deodorizing function, the back skin can be freely colored, and the wash resistance is excellent.

EXAMPLES Further details will be described in Examples. In the examples, "%" is "% by weight" unless otherwise specified.

The deodorant property of the textile product was evaluated by adding 300 ml of ethyl mercaptan to a 100 ml sample bottle containing 1 gr of the sample.
The amount of ethyl mercaptan contained in the sample head after 30 minutes and 60 minutes from the addition of ppm was measured by gas chromatography and calculated from the weight loss. Further, the quantification of copper in the deodorant and the textile product was measured by ICP emission spectroscopy. A sample of the wash resistance of shoes was prepared according to JIS L 1018 “household electric washing machine method”.

Production Example 1 Total monomer concentration 2 under the monomer composition conditions shown in Table 1.
Aqueous solution polymerization was carried out at 50 ° C. for 2 hours using 0%, potassium persulfate as a polymerization initiator and potassium carbonate as an auxiliary agent. The polymerization rates of the obtained polymers were all 90% or more. Next, after the monomer was distilled off, a sulfonic acid comonomer and an equivalent amount of copper sulfate were added, and the mixture was stirred and reacted at 60 ° C. for 1 hour.
Then, it was diluted with water to produce a 3% aqueous solution of the deodorant of the present invention.
