Description

Functional insole using precious serpentine}

The present invention relates to an insole that is inserted inside a shoe and comes into contact with the sole of the shoe wearer's foot. In particular, the insole is formed by mixing cork material and serpentine, which emits far-infrared rays, to improve the breathability, antibacterial properties, and deodorizing effect of the shoe, This relates to a functional insole that can promote metabolism and blood circulation by activating the body cells of the shoe wearer.

Generally, shoes include an outsole that forms the bottom of the shoe coupled with the upper, a midsole (midsole) laminated on the outsole, and an insole that is laid on the inner bottom of the shoe and laminated on top of the midsole.

Among them, the insole for shoes is located on the inside of the shoe in contact with the sole, absorbing sweat and salt released from the foot, improving the fit, and absorbing some of the shock applied to the sole when walking or cantering. It is used to perform a buffering role.

If left for a long time, the absorbed sweat and salt cause bacterial growth, causing not only bad odor but also eczema. It is a cause of diseases such as athlete's foot and athlete's foot.

To solve this problem, shoe insoles with good hygroscopicity, antibacterial properties, and ventilation are needed, and continuous technological development is being conducted to satisfy these conditions.

In order to improve the above-mentioned conditions among conventional shoe insoles, products have been proposed that process sanitary chemicals into textile fabrics to achieve antibacterial properties or contain sterilizing and deodorizing agents in metal ions or ceramic materials.

However, conventional shoe insoles as described above contain anti-odor or sterilization substances with a weak bond to the material, so it is difficult for the substances to perform their role continuously for a long time, and in addition to the problem of poor practicality, PVC, EVA, PE Foam , it had to be manufactured only from synthetic materials such as synthetic pulp, synthetic rubber, and urethane, which had little breathability of their own, and there was a problem of having to make holes to ensure breathability.

In addition, conventional shoe insoles use chemical adhesives such as bond when attaching functional materials, which not only reduces breathability but also reduces antibacterial properties, moisturizing properties, breathability, and elasticity, which are the unique properties of natural materials. There was this.
