Description

Manufacturing method and structure of shoes

The present invention relates to a structure and manufacturing method of oral footwear having a health promoting function that can enable the continuous radiation of a large amount of anions and far infrared rays, which can be helpful in the prevention and treatment of diseases.

Shoes are generally composed of soles, midsoles, insoles (or insoles), and upper leather parts (skin and endothelium) .When wearing shoes, the feet are trapped inside the shoes, causing sweat (moisture) from the soles of the feet. Excessive waste is exposed to odors, as well as the risk of athlete's foot, eczema and frostbite.

In recent years, oral implants of functional materials that emit far-infrared rays have been used to ameliorate the above problems or as a means of supplementary health maintenance.

This method can be used pharmacologically or functionally by injecting insoles containing metal materials such as copper, ceramic materials emitting far-infrared rays, green tea extracts, and herbal extracts, or by molding together the above-mentioned materials when forming soles. There are ways to anticipate the effect. In addition, the air outside the shoe is allowed to circulate inside the shoe during walking or exercise when the shoe is worn, or a specific antimicrobial agent or fragrance is inserted into the shoe, and the shoe is being worn. Structural improvement methods, such as a small amount of spillage into the interior space of a shoe, may be used.

However, when the insole or insole of the shoe is inserted into a chemical resin such as a ceramic material such as ocher, a metal material such as copper, or a vegetable material extracted from green tea and herbal medicine, etc. It is easily damaged by wastes, dust, etc.), and the function of antibacterial, deodorization, water absorption, prevention of athlete's foot and eczema, frostbite prevention and far-infrared radiation is drastically reduced, and the feet are slippery due to moisture (sweat) generated from the feet. It causes a feeling of wearing off.

Recently, in order to absorb the sweat, there is a case of adding a ceramic material having a combination of antibacterial, far-infrared radiation and strong moisture absorption rate such as charcoal and silica gel. Will result.

In addition, when a large amount of ceramic material having a water absorption function is inserted into the midsole or insole for absorbing a large amount of moisture (sweat), the shape maintaining ability and durability of the shoe, which is the original function of the midsole, are reduced, and the cushion which is the original function of the insole and The softness is reduced, the wear feeling is reduced, the manufacturing method of the midsole and insole is added to this ceramic material when molding the resins, so the area that the additive is in contact with the air becomes a problem in the function performance. have.

In addition, a method of inventing or absorbing the moisture (sweat) generated when the shoes are worn inside the shoes and outflowing the shoes during the wear is invented or devised. In most cases, the ventilation holes in the leather around the soles of the feet where the feet are most sweaty There is a method of forcing out or making a vent inside the window of the shoe and forcing it out by using the weight of the body through the sole of the shoe or the heel attached to the sole, but when it rains or passes through the water, It seems to have no great effectiveness, such as the problem that water is introduced into the shoes, and it is not commercialized and distributed in the market.

Another method is to attach a specific device to the inside of a shoe sole or a heel attached to a shoe sole to continuously supply antibacterial and fragrance substances to the inside of a shoe or to generate heat, The manufacturing cost increases and should be replaced periodically due to friction with the curved ground attached to the sole of the shoe, but it cannot be replaced easily, the durability of the device is weak, and the wearer's discomfort caused by the sweat generated is not considered. It is difficult to apply in general shoes, and it is not commercialized yet.

As described above, there is a limit in removing or removing a certain amount of water (sweat) generated in the shoe, and the method adopted or invented or devised to the shoe to date, the concern about health is increasing, and the far-infrared rays which are being developed recently. Insertion of antimicrobial and deodorant materials such as ceramic materials or wood vinegar, green tea and herbal extracts is also oriented in contact with the sole of the foot, and in most cases, the function required by contamination and damage to the sole of the sole is reduced or insignificant.

Accordingly, the present invention has been made to solve the problems of the above-described conventional method, the object of the present invention is to absorb all the moisture of the shoes (sweat) generated in the shoe for a long time and the breathable layer of the shoe Provides the structure of the shoe to be formed in the soles (soles, midsoles and insoles) and leather parts, and does not impair the shoe's original function in all parts of the shoe, and inserts a large amount of negative ion and far-infrared radiation material It is to provide a method of manufacturing.

Provided is a method of making a functional sheet used to manufacture insoles, midsoles, wire cores and heel cores of a shoe, comprising the steps, having a large amount of water (sweat) absorption and having the property of emitting negative ions and far infrared rays.

The manufacturing method of the functional sheet of the present invention will be described in more detail as follows.

First, we measure the weight of natural fiber (cut in advance so that the fiber length is about 5 ~ 10cm) from polyester yarn, viscose rayon yarn, and coconut shell. When the mixture is mixed well for about 15 to 20 minutes at a compounding ratio of 6: 1: 2.5, the liquid mixed with water and vegetable adhesive in a ratio of 9: 1 is mixed with this mixed yarn (moving speed: 4 to 5). M / min), and spray the functional material for anion and far-infrared radiation so that about 0.3 to 0.5% by weight of the mixed yarn is attached, and add it to the mixed yarn.

Next, the blended yarn is metered to the carding machine, and the web is formed to a thickness corresponding to 650 to 700% of the thickness of the functional sheet to be finally formed in the carding machine. The non-woven pad is molded to the required size (thickness and width).

Then, the molded nonwoven fabric pad is passed through the emulsion bond injector, which is cut off from the outside, at a rate of about 4 to 5 M / min, so that the molded pad is sufficiently absorbed by the emulsion and anion And a functional material emitting far-infrared rays is sprayed in an injector in a closed space to cohesive filling.

In addition, the pad filled with the functional material is moved to dry the hot air for about 30 to 40 seconds at a temperature of 70 ~ 80 ℃ in a hot air dryer in which the inner space is sealed, and three rolls coated with a silicone rubber of about 20 mm ( Roll) consisting of a roll) is passed through at a rate of about 4 ~ 5M / min and pressed to a high temperature of about 170 ~ 180 ℃ to produce a functional sheet.

Finally, by rolling the crimped functional sheet to the required length, the manufacturing process of the functional sheet is completed in the present invention.

In the production of the functional sheet according to the present invention, natural fibers collected from polyester yarns, viscose rayon yarns and coconut shells are used, but polyethylene, polypropylene, nylon, polyacrylates, rayon, cotton yarns, etc. may be used according to their purpose. Is possible,

As described above, the structure of the shoe such that the absorption and ventilation layer capable of sufficiently absorbing moisture (sweat) generated in the shoe of the present invention for a long time is formed on all the windows (sole, midsole and insole) and the leather part of the shoe. The method for producing a shoe having health promotion by inserting a large amount of anions and far-infrared radiation materials without impairing the original function of the shoe into all parts constituting the shoe and the shoe is not limited to the method described above, but the technical gist thereof. Various changes are possible without departing from the scope of the present invention.

6 is a result of comparing the functional sheet to the far-infrared application evaluation center of the Korea Institute of Construction Materials Testing Center and comparing the far-infrared emissivity based on the Black Body using the "FT-IR Spectrometer" at 40 ° C. Since it shows an emissivity of about 91%, it can be seen that the far-infrared radiation amount of the functional sheet of the present invention is large.

As can be seen from the above description, according to the present invention, all the constituents of the negative ions and far-infrared rays shoes which absorb moisture such as sweat generated while wearing the shoes from all the constituent parts constituting the shoe and contribute to the health of the body. By choosing a structure that can be released from the shoe, the durability of the shoe is maintained and improved, the soles of the soles are eliminated, and the antibacterial and deodorizing functions of the shoe can be obtained, as well as the prevention and treatment of athlete's foot, frostbite, and eczema.

As an example, the functional sheet produced by the present invention is the main component to be applied to the insole, midsole, core and heel core, suitable rigidity (tensile strength: 180Kgf / ㎠), durability, moisture resistance, moisture absorption (absorption), elasticity It has wear resistance (wear strength: 24.1mg / 5000 times) and bendability to reduce the aging of shoes such as deformation, breakage, and wear, and can be washed by separating the insole from the shoe. Deterioration or deformation and damage of the material is prevented, and has a deodorizing function as shown in Table 2 and the antibacterial function as shown in Table 3 by the action of a strong anion as shown in Table 1 and far infrared rays as shown in FIG.

In addition, the effects of anti-oxidation, activation, purification and weak alkalinization of cells and blood by anion, which have been proven in the medical field, and budding by activation of cell and blood circulation due to the increase of body temperature due to the expansion of capillaries due to far-infrared radiation The metabolism is promoted, which is effective in the wearer's fatigue recovery, neuralgia, blood circulation disorder, insomnia, visceral disease, gynecological diseases, etc., can help prevent and treat the disease.
