Description

[Detailed explanation of the idea] <Industrial application field> The present invention relates to shoe insoles.

<Prior Art> There have been various types of shoe insoles.One type of insole that emphasizes comfort is a so-called leather insole, which is made by cutting a leather sheet into the shape of the sole of the foot.

In addition, with emphasis on breathability, a coarse reticulated woven fabric A made of vinylidene chloride-based synthetic resin monofilament, a honeycomb interwoven fabric B made of the resin monofilament, and a fine woven surface woven fabric D made of the resin monofilament are sequentially layered. Shoe insole made by welding the periphery (Tokukosho)
49-48024).

This relates to the improvement of the shoe insole, which has odor absorption and anti-mildew functions in addition to breathability.Coarse mesh woven fabric A made of vinylidene chloride synthetic resin monofilament, honeycomb woven intermediate fabric made of the resin monofilament. Woven fabric B, sheet S made of the resin and/or vinyl chloride synthetic resin end fibers coated with a mixed latex mixed with activated carbon powder, copper powder, and magnetic powder and then heated, and the resin monofilament. The insole is made by sequentially stacking finely woven surface fabrics D and welding the peripheral edges, and the weight ratio of activated carbon powder, copper powder, and magnetic powder to latex 100 is 10 to 50 and 10 to 50, respectively. , 100 to 400, and the components of the latex used in the above mixed latex are nitrobutyl latex in weight ratio.
Sodium lauryl sulfate 0.5-1.5 to 100, sulfur
0.5-1.5, zinc white 0.5-1.5, vulcanization accelerator 0.5-1.5,
Shoe insoles with anti-aging agents 1 to 3 were published in 1986.
It is known from Publication No. 18204.

<Problems to be solved by the invention> However, the above-mentioned conventional shoe insole has the following problems.

First of all, the former leather sheet type shoe insole has a good feel (touch), but has poor breathability.
There was a problem in that the effect could not be expected in terms of odor resistance.

On the other hand, the latter two A・B・D or A・B・S・D
Although the type of shoe insole made by laminating the former has better breathability than the former, it is clearly inferior in feel. In recent years, the characteristics of shoe insoles such as breathability, odor resistance, and tactility have become even more sophisticated as lifestyles have become more sophisticated.

This invention was devised in view of the above-mentioned problems, and its purpose is to provide excellent tactility,
To provide a shoe insole that has both breathability and deodorization properties, and which is further improved in breathability and deodorization properties compared to conventional ones.

<Means for Solving the Problems> The shoe insoles of the present invention that can solve the above problems include coarse mesh woven fabric A made of vinylidene chloride-based synthetic resin monofilament and honeycomb interwoven fabric B made of vinylidene chloride-based synthetic resin monofilament. , vinylidene chloride-based synthetic resin nonwoven fabric F to which deodorizing enzymes are attached, vinylidene chloride-based synthetic resin monofilament satin sheet N, synthetic material that is present only in the area facing the heel of the sole of the foot or the protruding part of the toe root. It is characterized in that the leathers L are laminated in order and the peripheral edges of the laminated body are welded or partially welded.

Therefore, in the insole of the present invention, the synthetic resin monofilament satin-like sheet N is in contact with the protruding part of the toe root of the sole (hereinafter referred to as the front part of the sole), and the other parts, In other words, it is a half-leather insole in which the synthetic leather is in contact with the heel of the sole and the front of the protruding part of the toes (hereinafter referred to as the rear part of the sole). The above-mentioned deodorizing enzyme may be any enzyme that can at least convert or decompose substances that cause foot odor into odorless substances, and conveniently, powdered fixed enzymes commercially available as deodorizing enzymes may be used. A converting enzyme can be used. Such an enzyme can be attached to a nonwoven fabric by, for example, mixing with a viscous substance and applying the mixture. The above-mentioned viscous substance for fixing the enzyme is preferably one capable of absorbing and adsorbing malodorous substances and their decomposition products.

<Function> The shoe insole configured as described above has the following functions.

The A, B, F, and N laminated parts facing the front part of the sole exhibit breathability and odor resistance, and not only dry the toes, but also remove malodorous substances generated there from adhering to the F layer. The enzymes involved convert or decompose it into odorless substances.

On the other hand, A, B, the part opposite to the rear part of the sole of the foot.
Since the surface of the F/N/L laminated portion that comes into direct contact with the foot is made of synthetic leather L, it provides a pleasant feel to the foot. This part of the insole has less breathability than the part facing the front of the sole, but since it is close to the opening of the shoe, air circulation is good, and the synthetic leather L part is stepped on with the heel. As a result, the leather L portion is pressed and the air wrapped inside is discharged or sucked into the matte sheet N portion by a pumping action, thereby increasing the amount of ventilation within the shoe as a whole.

<Example> An example of the present invention will be described below based on the drawings, but the present invention is not limited thereby.

The shoe insole of this example is shown in the plan view of FIG.
As shown in the longitudinal sectional view of the figure, the synthetic leather L layer is provided only on the surface of the shoe insole 1 and in the portion facing the rear part of the sole.

The insole 1 consists of a coarse mesh woven fabric A made of vinylidene chloride-based synthetic resin monofilament, a honeycomb interwoven fabric B made of vinylidene chloride-based synthetic resin monofilament, and a deodorizing enzyme "Bio Datsushi" (registered trademark).
[Osaka Soda Co., Ltd.] coated vinylidene chloride synthetic resin nonwoven fabric F, vinylidene chloride synthetic resin monofilament satin sheet N, and synthetic leather L are sequentially laminated, and then the laminate is crimped from above and below with electrodes. , the peripheral edges are welded by passing a high-frequency current between the electrodes. In addition, the above-mentioned "biodash" is a neutralized clathrate with a biologically active substance. This biologically active substance is a substance with a molecular weight of 15,000 to 2,300,000, and is fixed using a clay material as a base by adding special enzymes and auxiliary enzymes to activate the decomposition action of these enzymes. be. Malodorous substances are quickly decomposed by active enzymes and absorbed and adsorbed by clay materials.

The A, B, F, and N laminated parts of the insole are highly breathable and cushioning, the F layer has a deodorizing function, and the L layer provides an appropriate texture and feels comfortable when stepped on. The pumping action at the end promotes air circulation throughout the shoe. Note that the immobilized enzyme applied to the F layer repeatedly converts malodorous substances into odorless substances, unlike activated carbon, which has a limited absorption capacity (adsorption amount of malodorous substances).

<Effects of the invention> As is clear from the above explanation, the insole of the invention uses A, B, F, and N laminations in the part facing the front part of the sole where breathability and odor resistance are especially required. In addition, the part facing the rear part of the sole, where tactility is especially required, is made of A, B, F, N, and L laminated layers, so that the functions required for each part are achieved. The result is a shoe insole that is fully satisfactory in all aspects, including breathability, odor resistance, and texture.

Moreover, by using a half-leather insole with synthetic leather L provided only in the part facing the rear part of the sole, pumping action occurs when the leather L is stepped on, further improving breathability. can get.

In addition to the deodorizing effect due to improved air permeability, the product uses immobilized enzymes that can repeatedly convert malodorous substances into odorless substances, so it exhibits excellent deodorizing properties over a long period of time.
