Method for making moisture-permeable waterproof shoes

Abstract

A method for making moisture-permeable waterproof shoes, comprising: (A) preparing a shoe upper, an inner cover base material, a waterproof unit, a shoe sole, and a shoe last. (B) Cutting the inner sleeve base material into a cut piece, the cut piece has a main face and two symmetrical side wings. (C) The main surface part and the side wing part are respectively welded by ultrasonic waves. (D) Covering the welded part of the cutting pieces with the waterproof unit, so as to cooperate with the cutting pieces to form a shoe-shaped inner cover. (E) putting the shoe-shaped inner cover on the shoe last, and applying a shaping adhesive to the outer surface of the shoe-shaped inner cover, and then drying. (F) Coating the sizing adhesive on the inner surface of the shoe upper, and then drying. (G) putting the shoe upper on the shoe last with the shoe-like inner cover and heating, so that the shoe-like inner cover and the shoe upper are shaped into a 3D shape with stiffness Moisture-permeable waterproof shoe cover. (H) Fixing the shoe sole to the bottom of the moisture-permeable waterproof shoe cover.

Description

technical field [0001] The invention relates to a shoe, in particular to a method for making a moisture-permeable waterproof shoe. Background technique [0002] Nowadays, shoes are a mature and developed industry, and there are many kinds of shoe products, such as casual shoes, sports shoes, long and short boots and rain boots... etc. Among them, casual shoes with uppers made of cloth, textiles or natural leather, Sports shoes and long and short boots can effectively discharge the sweat and moisture emitted by the user's feet when worn and used, but they cannot prevent external moisture from penetrating into the shoes; in addition, the upper Casual shoes, sports shoes and long and short boots made of plastic and leather can effectively prevent external moisture from penetrating into the shoes, but they cannot effectively absorb the sweat and moisture emitted by the user's feet. Going out often makes the user's feet feel quite hot and uncomfortable. [0003] Furthermore, th...

[0002] Nowadays, shoes are a mature and developed industry, and there are many kinds of shoe products, such as casual shoes, sports shoes, long and short boots and rain boots... etc. Among them, casual shoes with uppers made of cloth, textiles or natural leather, Sports shoes and long and short boots can effectively discharge the sweat and moisture emitted by the user's feet when worn and used, but they cannot prevent external moisture from penetrating into the shoes; in addition, the upper Casual shoes, sports shoes and long and short boots made of plastic and leather can effectively prevent external moisture from penetrating into the shoes, but they cannot effectively absorb the sweat and moisture emitted by the user's feet. Going out often makes the user's feet feel quite hot and uncomfortable

[0003] Furthermore, the rain boots are made by injection molding of rubber material. Although the rain boots themselves have the function of waterproofing, when worn, due to the relatively dense rubber material, the rain boots are relatively stiff and heavy. , often cause great burden and bending resistance to the user's feet, which is prone to discomfort. Moreover, this kind of rubber rain boots cannot discharge sweat from the inside to the outside. If worn for a long time, the user's feet will be damaged. The sweat and moisture discharged will be stuffed in this kind of rain boots, making the user's feet feel quite hot and uncomfortable

[0004] In addition, there are now some manufacturers who manufacture moisture-permeable and waterproof shoes with both breathable and waterproof functions. However, the vamp of this kind of moisture-permeable waterproof shoes is made of several pieces of vamp, and the vamp is sewn on the vamp. The protruding seams at the joints of the pieces tend to rub against the user's feet, which can easily cause discomfort and a foreign body sensation on the user's feet
