Accordingly, the air is moved to the front side through the air passage 15 by the inflation pressure of the first impregnated portion 14, and air is circulated to the entire sole by the inflation pressure again in the second pumping portion 16 .

In addition, since the second pumping portion 16 is configured such that the inboard thickness D2 is thinner than the thickness D1 in the foot outward direction when viewed from the cut surface, and the foot is naturally gathered naturally, Lt; / RTI >

The method for manufacturing a shoe sole to which the fragrance emitting member according to the present invention is applied is manufactured by the following process as shown in FIG.

First, a material mixing step (S10) for mixing the urethane material, which is the raw material of the bottom window (10) and the elastic member (20), and the incense emitting member of the chemical comprising the fragrance component is performed in a liquid state, A material input step (S20) is performed.

At this time, the lower mold uses a mold in which the bottom window 10 and the elastic member 20 are integrally molded.

Next, the fabric surface layer 30 is bonded (S31) to the upper mold, and a mold closing step (S30) is performed in which the lower mold and the upper mold are closely contacted with each other. A heat processing step S40 is performed in which the fabric surface layer 30 is fused to the surface of the raw material while being solidified in the shape of the bottom window 10 by baking.

A product separating step S50 for separating the solidified product from the metal mold and a step for forming the fabric surface layer 30 in the shape of the bottom window 10 And a product completion step (S50) for trimming (trimming) are sequentially performed.

In addition, in the step of injecting the material into the lower mold (S20), the lower mold may be formed as a separate mold so as to separately form the individual elastic body (S21) Process can be added.

In the first embodiment of the present invention, the bottom window 10 and the elastic member 20 are formed by integrally molding an incense emitting member, which is a chemical that emits a fragrance in the molding step, by mixing them together.

At this time, in the present invention, the raw material and the fragrance emitting member of the bottom window 10 and the elastic member 20 are mixed at room temperature, and after aging for more than 48 hours at a low temperature of 8 to 10 ° C, And the fragrance is deeply impregnated into the raw material of the elastic member 20, so that the fragrance can be maintained even for a long time.

In one embodiment of the present invention, the perfume emitting member per 1 kg of raw material of the bottom window 10 and the elastic member 20 is mixed at a weight ratio of 5 to 7 g.

The fabric surface layer 30 is formed with a plurality of ventilation holes 31 at the front side thereof so as to facilitate circulation of air when walking on the antibacterial honeycomb structure.

Particularly, the fabric surface layer 30 is provided with an elastic groove 33 for forming a line-shaped antimicrobial line 32 containing silver grains at regular intervals in the transverse direction and forming a solid honeycomb structure (honeycomb structure) .

At this time, the elastic groove 33 is a woven product formed in a depth direction in a '↖ ↗' structure, which is compressed by pressing and is elastically restored.

Therefore, the antibacterial line 32 suppresses bad bacteria causing the bad smell, and the air circulation is improved by the elastic groove 33, so that the wearing feeling can be improved.

Meanwhile, the present invention can be configured with various elastic members 20 having different materials so as to exhibit a more improved cushioning effect.

First, the front elastic member 20a is made of an elastic material having physical properties such as impact absorption and high repulsion elasticity, absorbing the impact to the maximum, improving the comfort and fatigue prevention performance by energy return, A function to facilitate walking is implemented.

The middle resilient member 20b is formed in an ergonomic shape that is formed by a curved line corresponding to the shape of the sole so that the middle portion of the sole that is in close contact with the inclined portion is not pushed forward and slowly restored to its original shape after compression It is made of material. Therefore, the intermediate elastic member 20b is constructed to have a slip prevention function when walking while slowing down the restoration time after compression, and a space is generated when the foot is lifted, thereby enhancing air permeability.

The rear elastic member 20c is formed by laminating two or more elastic materials having different compressive stresses so as to absorb the pressure of the heel to which the shock is most transmitted, thereby achieving both functions of comfort and shock absorption. Therefore, the rear elastic member 20c according to the present invention absorbs the impact of the backgauge to which the initial pressure is applied at the time of walking, thereby greatly contributing to joint protection from the ankle, knee, hip, waist, and throat.

The upper surface of the fabric surface layer 30 is bent by the protrusion of the front elastic member 20a, the intermediate elastic member 20b and the rear elastic member 20c to the bottom window 10, And the impacted side is absorbed by walking on each part of the sole.

Therefore, the present invention combines a plurality of elastic members having elasticity and different materials capable of absorbing the most appropriate impact to the portions where the soles of the feet are closely contacted to load different loads, thereby providing comfort to the user on walking and preventing musculoskeletal symptoms And the incense dissipating member is included, and the effect of removing odor from the foot is excellent.
