Description

METHOD FOR MANUFACTURING BOOTS

The present disclosure relates to a method for manufacturing a boot, and more particularly, to a method for manufacturing a boot with improved cold protection effect.

In general, boots are made of various shapes and materials according to the purpose of use, consisting of a body part that covers the instep and calf and a sole that supports the sole.

Specifically, the boot is composed of a body portion formed of a space where a foot and a foot are made of a rubber or synthetic resin material, which is fused to each other, and a foot can enter therein. The inner end of the ester material is additionally attached and manufactured.

However, the endothelium of the boots manufactured by the prior art is a mesh-type polyester material, which has a slight elasticity and flexibility to help improve the fit, but there is no volume feeling and poor cold performance. Therefore, in order to manufacture a boot with sufficient volume and cold resistance, it is necessary to use a material such as boa hair instead of polyester as the material of the inner skin.

However, if the boots are manufactured using the inner lining of the fur material, there is a problem in that the part of the fur formed inside the inner lining is completely laid by the pressing force in the process of injection injection of rubber or synthetic resin. Due to this, there is a problem that the warmth function is deteriorated because the volume of the hair part is not only lost, but the ankle and the upper part of the wearer are not effectively wrapped.

Therefore, there is an urgent need for technology development research on a method of manufacturing a boots with enhanced thermal insulation function.
