Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a shoe insole mixed with magnetic chips made of magnetic tape.

[Problems to be solved by the invention]

Conventional shoe insoles are generally used for adjusting the dimensions of feet and shoes or as cushions, and their use is limited.

Some shoes have been devised so as to absorb the moisture inside the shoes, but they have not been able to sufficiently remove bad smells or the like because they do not provide a significant effect.

An object of the present invention is to provide a shoe insole which has a sterilizing and deodorizing effect by mixing magnetic chips made of a magnetic tape, improves blood circulation in the foot, and is light in use and comfortable.

[Means for solving the problem]

In order to achieve the above object, the shoe insole according to the present invention is obtained by processing magnetic tape into fine filaments and mixing magnetic chips, which are magnetized, with a non-woven fabric material at an appropriate density, and processing and molding this into a plate shape. It is.

 The magnetic chips are preferably magnetized to 3 to 15 Gauss.

[Action of the invention]

In the present invention, 3 to 3
Since the magnetic chips made of magnetic film magnetized to 15 Gauss are mixed in, the odor hardly occurs in the shoes. This is thought to be because the germicidal action suppresses the growth of bacteria.

Also, when used in winter, you will feel the warmth. This is considered to be due to the improvement in blood circulation of the feet due to the magnetic action of the magnetic chips mixed into the insole.

Furthermore, in addition to the base material being a non-woven fabric, a fine space is formed inside the filament magnetic chips and between the magnetic chips and the base material, so that air permeability is maintained, and the materials are a non-woven fabric and a magnetic tape. It is lightweight and does not feel uncomfortable due to the inclusion of a magnetic body.

[Example of the invention]

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, the shoe insole 1 of the present invention is obtained by processing a magnetic tape into small pieces of a magnetic tape and magnetizing the magnetic chips 3 in a plate-like base material 2 made of a nonwoven fabric at a desired density. Are mixed.

As shown in FIGS. 2a to 2c, the magnetic chips 3 are provided with a magnetic layer composed of a magnetic material such as ferromagnetic iron oxide, chromium dioxide and alloy powder and a binder on a support of a synthetic resin film such as a polyethylene terephthalate film. A so-called magnetic tape (whether used or produced during the manufacturing process) is used as a material, and the magnetic tape is wound so that the magnetic layer is on the outer side. The filament is plastically deformed, and the filament is cut into a length of 1 to 10 mm to form a small piece 2 ', and the small piece is magnetized to 3 to 15 Gauss by a magnetizing device.

 Next, an embodiment of a method for manufacturing magnetic chips will be described.

As a material of the magnetic chips 3, a magnetic tape having a film support having a thickness of 3 to 25 μm, a magnetic layer having a thickness of 3 to 10 μm, and a width of 8 to 16 mm is preferably used.

As shown in FIG. 2b, in the process of unwinding and winding the magnetic tape 4 at a constant speed, a heating unit 5 such as an electric heating device is provided at an appropriate position in the middle of the magnetic tape 4, and a constant temperature (for example, 120
C. to 250.degree. C., preferably 200.degree. C.) for a predetermined time (for example, several seconds to several tens seconds, preferably 2 to 5 seconds),
When the take-up speed of the take-up roll 6 is made larger than the payout speed, and a tension of about 2 to 5 times the stretching ratio is applied in the longitudinal direction of the magnetic tape superheated at the position of the heating unit 5,
The tape 4 is stretched in the longitudinal direction, and the filament 7 is obtained in which both sides of the tape are plastically changed so as to be wound inward with the magnetic layer outside.

FIG. 2c shows an enlarged cross section of the filament 7 obtained as described above, which is plastically changed into a filament wound with the support 8 inside and the magnetic layer 9 outside.

The thus obtained filament 7 of 1,000 to 3,000 deniers, preferably 2,300 to 2,600 deniers, is cut into small pieces of 1 to 10 mm, preferably 5 mm in length, and this is cut into about 5,000 to 8,000
When placed in the porcelain of a 0 Gaussian permanent magnet, these pieces are instantaneously magnetized to 3-15 Gauss.

In addition, even if the above-mentioned magnetic tape fiber is placed in a magnetic field of the same strength without being cut, it is magnetized to only about 2 Gauss at best, and is magnetized to 3 to 15 Gauss only by subdividing it into 1 to 10 mm. It was confirmed that it would be.

The magnetic chips 3 are scattered at an appropriate density on the sponge-like synthetic resin nonwoven fabric material 10 as shown in FIG. 3a, and thereafter, when the nonwoven fabric material 10 is heated and compressed, as shown in FIG. 3b,
Nonwoven fabric plate 10 'with magnetic chips 3 mixed therein
Is formed.

This plate material 10 'is formed into a desired insole size as shown in FIG. 3C by punching, cutting or the like, whereby the shoe insole shown in FIG. 1 is formed.

[Effect of the invention]

As described above, the shoe insole of the present invention has the sterilization and deodorizing effects obtained by mixing the magnetic chips processed from the magnetic tape into the base material made of non-woven fabric as described above, and is hygienic and promotes blood circulation, Good for health.

Further, since the material is a non-woven fabric and a fiber made of a magnetic tape, it is lightweight and rich in air permeability, and there is no sense of incongruity mixed with a magnetic material.
