Modern people spend most of their day working outside. Therefore, about 700 tons per day (weight 70kg, 10,000 steps) will be applied to the foot, the lowest structure of the human body.

The foot is composed of 52 bones, 60 joints, 214 ligaments and 38 muscles, including one-fourth of our body, and numerous blood vessels.

For this reason, the Chinese medical text 'foot foot reflexology health law' said that all the organs of the human body are connected to the soles of the feet, which is a miniature version of the human body. Therefore, the health of the foot is directly connected to the health of the whole body, the skeleton of the instep is firmly connected to each other to support the weight evenly and to play a role of absorbing the shock when walking.

The big toe acts as a lever to move weight from one foot to the other, and each toe grips the ground to help move forward, while the heel of the foot helps balance the body with minimal energy consumption. It is to play a role.

Therefore, the importance of the shoes worn on the feet as described above is incredibly enormous, and should be designed in consideration of the design and hygiene aspects as well as the design of these shoes.

Ordinary shoes such as shoes and sneakers, or leisure shoes such as golf shoes and hiking boots are worn for a relatively long time, and the moistness of the feet and fungi occurs due to sweat or moisture generated during walking or exercise. It is worsening your health.

Therefore, in recent years, various new materials or new products have been released one after another, and efforts to comfort the interior of the shoes have been repeated, but the effect is weak, and most of them have only tried.

In addition, as described above, the sole of the wearer's sole is almost blocked from outside air, so when sweat occurs a lot in summer, such as bad smell of shoes as well as the wearer's foot, it is not very good for hygiene.

In summer, the ventilation is not smooth, so the temperature inside the shoes rises rapidly, and moisture, which is the main cause of germ growth, is continuously accumulated. In winter, the sweat generated from the feet takes away the body temperature, which makes it more cold. will be.

The present invention has been made to eliminate the problems described above, by forming a separate functional printing layer on the front and rear of the shoe lining material or the sole, while also responsible for the antibacterial and deodorant function inside the shoe from the printing layer, Abundant anions and far-infrared rays are radiated to promote the health of the feet, and have a constant temperature function by the cold and heat function materials to maintain the temperature similar to the human body temperature in the summer or winter to obtain a more comfortable feeling of wearing shoes.

On the other hand, the above-mentioned PTT (Poly Trimethylene Terephthalate) fiber is a fiber developed by the Ministry of Commerce, Industry and Energy, Korea Institute of Industrial Technology, and a research center for three years, and has a high elasticity function and a recovery function of fabrics. It is a state-of-the-art fiber that has been newly designed and developed by using the poly merzation process (Poly merzation).

In addition, the anionic powder is finely divided by crushing tourmaline (Tourmaline) ore, tow extraction and calcining, has a viscosity of 4000 ~ 8000 cps, grayish white and has the appearance and color like sticky grass, and has a hydrogen ion of 7.5 It has concentration and properties of anionic complex emulsion viscous polymer compound.

In particular, the anion powder emits a large amount of negative ions and far infrared rays, so cell activation and blood purification, metabolism enhancement (fatigue recovery), mental stability, allergy constitution improvement, waste discharge and the like can be expected.

In addition, silver nano is composed of a colorless transparent milky white liquid having a particle size of 10 to 50 nm, and is a polymer composite of silver nano ions having ionicity of a weakly cationic dispersed polymer and having a solid concentration of 40%. Should be.

Silver is a jewel that has been used as a tool to check the imbalance of the body when worn on the body, and has been used as a silver pill to prevent gynecological diseases, herbal medicine, and to clear blood when it is powdered.

Strong sterilization, antimicrobial and electromagnetic shielding capacity is maximized, has more than 650 kinds of various pathogens, bacteria, bacteria, fungi, etc. sterilization function and propagation inhibitory ability, there is no resistance to antibiotics, harmless to the human body.

In addition, the cold and heat functional material is composed of a spherical capsule having a particle size of 1 to 4 μm, and is a milky white aqueous polymer resin, which is in the form of a phase transfer material (PCM) and does not contain ions. Having a hydrogen ion concentration of 7.5 PH,

Phase transfer material (PCM), which is a drug with automatic temperature control, serves to absorb or store and transfer heat according to external temperature conditions.

At this time, the cold and heat function materials should be made of materials that are harmless to the human body.

In this material, looking at the manufacturing process of the anion powder,

Since the anion powder is manufactured at the particle size level of the ion, the particle size of about 10-50 nm is used, and it acts as a processing method that can be semi-permanently preserved, such as antibacterial, deodorant, durability of the laundry.

The anionic powder is made of tourmaline as a raw material, and the tourmaline particle size is crushed and mixed with water, and the shredded tourmaline particles are mixed with sodium chloride (Nacl) about 5%.

Mixing sodium chloride by about 5% will prevent the growth of bacteria. According to the dental engineering literature, sodium ions (Na ⁺ ) enable the preservation of permanent teeth in the mouth and the suppression of bacterial propagation even if food is stuck in the teeth, and prevents bacterial penetration in the body.

When sodium chloride is mixed with water mixed with tourmaline as described above, sodium chloride reacts with water and sodium ions (Na ⁺ ) and chlorine ions (Cl ⁻ ) are present in the aqueous solution.
At this time, the chlorine ion (Cl ⁻ ) is preferably removed by adsorption using an ion exchange resin method. Sodium ions (Na ⁺ ) in the aqueous solution will remain as a bacteria propagation inhibitor.

The next step is to fire the discharged tourmaline tow, and the firing temperature is removed in three steps such as 600 ° C, 900 ° C, and 1200 ° C.

Primary firing is a process to remove lead (Pb) and arsenic (As), which are toxic substances. The method of removing lead is to use a device that melts lead at 600 ℃ and falls down using heavy specific gravity. It can be usefully used. Toxic substances such as arsenic can be removed by volatilization above 1560 ℃.

Secondary firing is a process for lightening the color of tourmaline, and at this time, the reduction furnace calcining method at 900 ° C. is used to reduce the color of the tourmaline to the gray-white level by the reduction furnace method.

Tertiary firing, 'indirect heat firing method' may be used, in this process is to expand the internal pores of tourmaline, to remove impurities by burning fine amounts of impurities such as arsenic, and to increase the deodorizing function. Specifically, indirect thermal calcining is performed at a temperature of 1200 ° C. for a long time so that impurities such as arsenic are volatilized while many pores of nano size are generated in tourmaline.

When micronized for use in fiber through the tourmaline crushing and crushing process completed tertiary firing, when the bamboo charcoal powder is finely mixed by 5%, the tourmaline grain size is lighter and the color becomes lighter.

Bamboo charcoal has a white charcoal color, so it is white and can be applied and applied in various colors.
