Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to clothes, shoes, bags,
The present invention relates to a woven fabric leather processed from animal natural leather such as cowhide, pig leather, deerskin, sheep leather, and horse leather used for daily necessities such as bags.

[0002]

2. Description of the Related Art Natural leather of various animals such as cows, pigs, deers, sheep, and horses is used as an important material in daily necessities.
In addition to shoes and bags, it is often used for clothes such as jumpers, jackets, coats, trousers, etc.Especially for apparel goods, fashion is regarded as important, and various clothes are used as a substitute for cloth with various designs. It is becoming. By the way, the leather used for conventional jumpers, jackets, coats, trousers, etc., uses the skin of the tanned leather as it is on the front side of the clothing fabric,
Alternatively, the suede leather is used with the suede surface of the leather facing the garment. In addition, applicant's patent no.
No. 53690 develops a jeans-like garment leather in which a pattern of jeans fabric is formed by embossing on a suede-treated surface of a tanned leather, partially buffed and washed away.

[0003] When the tanned leather is used as it is on the front side of the garment, the backside of the garment is used as it is, and the back of the garment feels irritating to the skin. That means you have to line your clothes.

[0004] On the other hand, in any case of suede-processed leather or jeans-like clothing leather, the backing of the leather is used as the upper surface of the suede surface, and the glossy surface of the outer surface of the silver surface is used as the clothing surface. Therefore, in the clothing using these, the glossy surface of the tanning skin, for example, the tanning skin of chrome tanning, comes to the skin side inside the clothing. In this way, when the glossy surface of the silver surface comes to the back of the clothes, no fluffing occurs. However, if the glossy surface of the silver surface directly touches the skin, it will stick to the skin and feel unpleasant and feel hot. Furthermore, chrome tanned skin is not good for the skin because some chromium permeating the skin causes allergy to the skin and its use is banned or banned in some countries. For this reason,
Usually, garments made from these leathers will be lined, requiring an extra sewing process for them, and when it comes to total backing, it may be warm for winter wear, but it is hot from spring to autumn, It cannot be worn refreshingly.
