Abstract

The present invention relates to a functional out sole (10) having a function of releasing far infrared rays and anions used in footwear, and far-infrared and anion emitter powder (polyurethane ilneurite, tourmaline, zeolite, sulfur) , Silver (Ag), copper (Cu), a colorant, a material in which some or all of the powdery materials such as bamboo charcoal and metal oxides are mixed, hereinafter referred to as a functional material.) And the blowing agent are mixed at an appropriate ratio and compressed. To the molded sole 11 is characterized in that the flexible epoxy pack 12 of about 3mm ~ 6mm thick containing a large amount of the functional material is attached.

The functional outsole of the present invention is hardened by the physical properties of the polyurethane, the sliding and wear rate of the bottom surface is reduced, and the wearing comfort is improved by the shock absorption action by the soft epoxy pack containing a large amount of functional material.

In addition, anion and far-infrared rays are radiated by the action of the functional material contained therein, and as is well known, antibacterial, deodorization, heat, fatigue of the wearer's feet and spine, and the like can be obtained to promote blood circulation.

Description

Functional Out Sole for Footwear

The present invention is made of polyurethane resins in functional materials (far-infrared and anionic emitter powders, powdered materials such as Youngdong acid ilneurite, tourmaline, zeolite, sulfur, silver (Ag), copper (Cu), colorant, bamboo charcoal and metal oxide) The material is a mixture of some or all of the material, hereinafter referred to as a functional material) and the foaming agent are mixed in an appropriate ratio and foam compression molding to harden the properties of the molded sole, reducing the fatigue of the foot, The coefficient of friction increases, the sliding is reduced, the wear rate is reduced, and the shock absorbing and dispersing action of the soft epoxy pack protects the foot from strong impacts beyond normal walking activity.

In addition, the soft epoxy pack with a thickness of 3mm to 6mm embedded in the upper groove of the sole and the functional material contained in the sole provide strong antibacterial, deodorization, heat, fatigue of the wearer's foot and spine, and promote blood circulation. The effect was obtained.

In general, as shown in Figure 2, the sole of the shoe is in contact with the ground, absorbs external shocks and serves to support the weight, the polyurethane foam outsole is comfortable to wear, such as sneakers or casual shoes, Although it is mainly used for the purpose of improving the foamed polyurethane, it has a lot of pores, and because it has a soft property, wear is good, so it is weak in durability, and when the protrusion on the bottom is worn, the index of friction is sharply decreased to increase the slippage. The wear of the shoes will adversely affect the wearer's gait and foot growth and health.

Therefore, the present invention adds a functional material during the foaming of the polyurethane so that the foamed polyurethane has a function of increasing durability and emitting far infrared rays and anions, thereby reducing the wear rate and sliding of the bottom surface, and having a high function on the upper surface in contact with the foot. By inserting the anion and far infrared emitter of, the large amount of anion and far infrared ray are continuously released and absorb and disperse the shock generated when walking.Anion and deodorization, prevention of athlete's foot and eczema by the action of anion and far infrared, foot heat It is to provide a functional sole having a multifunction, such as frostbite prevention and foot fatigue reduction.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a diagram showing the sole of the object of the present invention is a description of the role and indirect use of the sole in the shoe.

1 is a perspective view and a partial cross-sectional view of the present invention functional outsole (11) polyurethane foam compression sole of Figure 1 is a polyurethane foam as the main material by adding a foaming agent and a functional material, foam compression at high temperature It is molded, and becomes a key component of the present invention.

An adhesive is applied to this polyurethane foam compression sole (11) to form an adhesive layer (12), and a foaming agent and a functional material are mixed in a soft epoxy to absorb shock and emit a large amount of anions and far infrared rays. The flexible epoxy pack baked for 30 minutes at the temperature of 80 degreeC is attached so that it may become more than 50% of the sole area.

3 is based on the Black Body using the "FT-IR Spectrometer" at 40 ℃ far-infrared emissivity for the polyurethane foam compression sole, the main component of the functional sole of the present invention commissioned by the Korea Institute of Construction Materials Evaluation Center It is a result of the contrast measurement, and shows an emissivity of about 91% at 6㎛ ~ 20㎛, it can be seen that the functional sole of the present invention is far infrared radiation dose.

By adding a functional material to the functional soles used in the footwear of the present invention, it is not only comfortable to wear, but also has a low wear rate on the sole surface of the sole, and prevents slippage, and the radiation effects of commonly known anions and far-infrared rays (antibacterial, deodorization, foot heat) , Athlete's foot and eczema prevention, fatigue reduction, blood circulation, etc.) occurs, and the soles of the present invention was commissioned by a certified testing laboratory for the characteristic test analysis, the results are shown in Table 1, Table 2 and Table 3 below.
