Description

Manufacturing method of antibacterial shoe insole and antibacterial shoe insole manufactured thereby

The present invention relates to a method for manufacturing an antibacterial shoe insole and an antibacterial shoe insole manufactured thereby, and more particularly, by manufacturing a shoe insole using an antibacterial material, inhibiting the growth of mold or microorganisms that may be generated inside the shoe And it relates to a method of manufacturing an antibacterial shoe insole that can help the wearer's foot health by radiating a large amount of far-infrared rays beneficial to the human body, and to an antibacterial shoe insole manufactured thereby.

In general, a shoe insole is a component of a shoe that is inserted into the sole of the shoe and comes in direct contact with the sole of the wearer, and should be manufactured to be comfortable to wear while minimizing the fatigue of the foot due to walking even if the shoe is worn for a long time.

As is well known, these shoe insoles are shaped according to the shape of the bottom surface of the inside of the shoe, and are manufactured using cushioning materials so that the wearer can feel comfortable and less fatigued while walking.

However, in the case of shoes such as sneakers, the cushion material itself has heat retention, so when walking for a long time while wearing these shoes, a lot of heat is generated and accumulated on the floor inside the shoes, and the generated heat is not easily released, so it is difficult to take off the shoes. In some cases, an unpleasant foot odor is generated.

In addition, the soles of the feet have more sweat glands compared to other parts, so that a good environment for bacteria to live inside the shoes is easily created.

Accordingly, it is a shoe insole that can minimize the odor generated when wearing closed shoes for a long time, as well as protect the feet from various bacteria such as athlete's foot, E. In response to this demand, insoles of various materials have been proposed.

As one of such methods, a method of adding an inorganic antibacterial agent such as silver nanoparticles to a shoe insole in order to sterilize bacteria in the shoe and remove odor has been proposed.

However, such an inorganic antibacterial agent can be applied to a shoe insole by diversifying its types and functions to perform an antibacterial and deodorizing action. There was a problem in that the antibacterial agent was easily peeled off from the insole or lost its function in a short period of time.

The hydrocarbon terminus of peracetic acid easily penetrates into microbial cells such as bacteria and breaks down the SS and SH bonds inside and outside the microorganism, thereby inducing rapid and effective antibacterial activity.

When peracetic acid is in contact with an organic material, an atomic oxygen radical is generated as shown in Scheme 1 below, and the generated oxygen radical oxidizes the contacted organic material to exert a sterilizing effect.
