Description

[0001] MIDSOLE COATED ADHESIVE MATERIAL [0002]

The present invention relates to a midsole coated with an adhesive fabric, wherein an outer surface of the low-hardness midsole is coated with an adhesive fabric woven into a mesh, thereby improving the cushioning and flexibility by the low- Thereby preventing wear or wrinkling of the midsole due to the adhered fabric and also maintaining the flexibility and improving the wear resistance.

In general, the shoe comprises an outsole 10 in contact with the ground as shown in Figs. 1 and 2, a midsole 20 provided on the top of the outsole 10, An insole 30 provided on the upper part of the footrest 20 so as to be in contact with the soles of the foot and an upper part 40 coupled to the midsole 20 to surround the foot.

In particular, the midsole is a member having a cushioning function for absorbing an impact applied to the foot or sole during walking, and is usually made of a foam obtained by foaming various synthetic resins (for example, polyurethane, EVA, etc.) A significant portion of the impact caused by the contact with the ground during walking may be transmitted to the body to cause fatigue or discomfort, and joints and muscles may be damaged when walking for a long time.

In other words, the cushion function of the midsole is a very important part when considering the function of the shoe, and the midsole can improve the cushion function of the midsole when it is formed with a low degree of hardness (for example, about 25 to 30 (asker A) .

However, when the hardness of the midsole is simply adjusted to the lower hardness, the cushioning property and the flexibility can be satisfied. However, when the long time walking, the midsole is collapsed by the load (the collapse means that the midsole is completely or partially pressed by the load ) Or wrinkles are liable to occur and wear resistance becomes very weak.

As a method for solving this, the configuration of Patent Document 1 can be adopted. Specifically, Patent Document 1 has a structure in which a polyethylene-based synthetic fiber or a non-woven fabric 8 is coated on the lower surface of the midsole 4, as shown in Fig.

In the patent document 1, the synthetic fiber or the nonwoven fabric is used as a crosslinked material for improving the adhesiveness. However, if the synthetic fiber or the nonwoven fabric is employed for the purpose of improving the cushioning property, the outer surface of the low- (For example, hardness of about 35 to 50 (asker A)), while improving the cushioning property of the midsole.

However, when the outer surface of the midsole is simply coated with a fabric such as a synthetic fiber or a nonwoven fabric, the flexibility of the midsole may be considerably weakened by the fabric. In consideration of the walking operation of the shoe which repeats the folding operation , Causing the function of the shoe itself to deteriorate.

In order to solve this problem, it is possible to consider the covering of the mesh fabric having the through holes. In other words, when the mesh fabric is coated on the outer surface of the low-hardness midsole, it is possible to improve the cushioning property and to compensate for the collapse of the midsole, the wrinkle or the weak abrasion resistance. Further, the through hole portion (the portion not covered with the midsole) Flexibility will also be secured.

However, when a general mesh fabric is used on the outer surface of the midsole as described above, in order to cover the midsole, it is essential to use various kinds of pre-treatment and surface treatment on the midsole and then use an adhesive. There is a problem that not only the problem is caused but also the value of the product is deteriorated due to contamination of the midsole by the adhesive.
