にくい革靴の加硫製法に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for vulcanizing leather shoes which is hard to lose its shape by attaching a rubber core material which is flexible and excellent in shape retention to a toe or a heel of a leather cap.

ため、硬いが保型性のある材質が要求されている。2. Description of the Related Art In recent years, footwear has generally become lighter and more casual, and even in leather shoes, the core material used in connection with the softening and softening of the upper, the core material such as the moon shape is hard to prevent fitting and shape loss. Materials with shape retention properties are required.

載の芯材を革靴に用いると弾性がないため長期間履き続
ける間に踵を踏み付けたり、靴内の汗を吸収することで
型崩れが起こり易く、一度型崩れするともとの形状に復
元し難い点がある。However, when the above-mentioned core material is used for leather shoes, it has no elasticity, so that it is easy to lose its shape by stepping on the heel while continuing to wear for a long time or absorbing sweat in the shoes. However, once it loses shape, it is difficult to restore the original shape.

易い等で裁縫時の作業性が良好でない。[0005] Further, since the core material is very hard, when sewing the core material, it is possible to perform sewing by heating and softening the core material,
When the continuous operation is performed, the sewing machine needle has heat, so that the resin of the core material is softened, the needle comes off poorly, thread breakage easily occurs, and the workability at the time of sewing is not good.

０〜１１０℃で架橋するゴム芯材でなくてはならない。Rubber has properties such as elasticity when vulcanized, but in order to make leather shoes using a rubber core which has already been vulcanized, the rubber core is adjusted to the shape of the last one by one beforehand. Since it must be vulcanized, it is not good in the working process. Therefore, the core material is sewn to the upper in the state of unvulcanized rubber in the same way as in the method of manufacturing vulcanized general cloth shoes, and the shoe upper is conformed to the last mold with a counter dresser, etc. By sulphating, leather shoes that are faithful to the last and have a sharp mouthpiece shape can be obtained. However, since the leather cap is simultaneously vulcanized, the temperature is such that the leather does not shrink.
It must be a rubber core material that crosslinks at 0-110 ° C.
