Leather shoe and making technology thereof

Abstract

A leather shoe and its manufacturing process, comprising a sole, a midsole, a heel and a shoe upper, a welt is provided at the forefoot of the shoe upper and the forefoot of the midsole, the welt is located around the forefoot, and the semi-finished sole, midsole, shoe The process of sewing the heel and the upper includes: first, the peripheral position of the forefoot of the midsole and the peripheral position of the forefoot of the upper are sewn together by cooperation with the welt; The cork layer is provided with a connecting layer at the arch of the shoe upper and the arch of the midsole, and then the arch of the midsole and the arch of the upper are sewn together with the connecting layer; the lower surface of the connecting layer and the lower surface of the welt At the same mating surface, finally the peripheral position of the forefoot of the sole is pasted or sewn together with the welt, and the arch of the sole is pasted or sewn together with the connecting layer.

Description

technical field [0001] The invention relates to a leather shoe and a manufacturing process thereof, in particular to a leather shoe using the Goodyear manufacturing process. Background technique [0002] In the existing leather shoes using Goodyear's production process, when sewing shoes, the inner welt and the outer welt are double-stitched to firmly clamp the upper and the sole into one body, which can withstand any impact and kink. A cavity is formed between the midsole and the sole, which can be isolated from moisture, and a layer of cork is laid to ensure the maximum breathability of the leather shoes. In addition to ensuring the function of thorough perspiration, natural footprints will also be formed on the sole. , in the first 15 days or so of the customer's wearing, with the force of the foot, the sole will be reshaped and become a "personal sole" that matches the foot shape, achieving a comfortable fit when walking, but the traditional In the process, the inner we...

AI Technical Summary

Problems solved by technology

A cavity is formed between the midsole and the sole, which can be isolated from moisture, and a layer of cork is laid to ensure the maximum air permeability of the leather shoes. In addition to ensuring the thorough perspiration function, natural footprints will also be formed on the sole , in the first 15 days or so when the customer wears it, with the force of the foot, the sole will reshape and become a pair of "personal soles" that match the shape of the foot, achieving a comfortable fit when walking, but the traditional In the process, the inner welt and the outer welt are wrapped around the entire sole or the peripheral position except the heel. At the same time, in order to ensure the firmness of the connection, the width of the welt should not be too narrow, otherwise it cannot be sewn or it will not be firmly attached to the sole. , so there is also a certain width of welt at the arch of the foot to connect with the sole, and the sole should also keep the same width as the welt, that is, the arch of the foot is too wide, and the material used for the sole is more Waste also increases the weight of the whole leather shoe, and the wide arch of the foot restricts the shape of the leather shoe, which is not beautiful
