A waterproof shoe and its manufacturing method

Abstract

The invention discloses a pair of waterproof shoes. The pair of waterproof shoes comprises a shoe sole and a shoe body fixed at the upper part of the shoe sole, wherein the shoe body is mainly composed of a waterproof shoe cover and a lining layer, the waterproof shoe cover is composed of two or more waterproof material sheets, each waterproof material sheet is formed by compounding a waterproof membrane as well as a surface layer and a nylon net layer which are respectively fitted at the two sides of a waterproof membrane, a special waterproof adhesive tape is pasted at a joint between two waterproof material sheets, the lining layer is matched with the interior of the waterproof shoe cover, and the lining layer is fitted at the inner side of the waterproof shoe cover and is fixedly connected with the waterproof shoe cover through suture fixation by virtue of a stitching machine at a shoe throat. The pair of waterproof shoes has the advantages that the waterproof membrane is directly pasted at the back of the surface layer, thereby being more breathable, and water can not enter an interlayer space between the waterproof shoe cover and the lining layer in a wearing process, so that the shoes can not become heavy, and feet can not be frostbited after sudden drop in air temperature; besides, the whole joint of the waterproof shoe cover is smooth, and waterproofness of the bottom of the shoe body is extremely stable; moreover, the whole sealed waterproof shoe cover can be tested, so that any defective product used for producing the finished product can be completely eradicated.

Description

technical field [0001] The invention relates to shoes, in particular to a waterproof shoe and a manufacturing method thereof. Background technique [0002] Traditional waterproof shoes are mainly divided into two types, socks and OUTDRY. [0003] Such as figure 1 As shown, the sock-type waterproof shoes are first made of a composite waterproof sheet into a closed structure with a needle car, and the pinholes are sealed with a hot air blower and professional waterproof tape to make it a sealed waterproof liner (commonly known as a waterproof sock); then The above-mentioned waterproof liner is combined with the pre-made outer vamp (non-waterproof) by sewing to form a complete vamp. Sock-type waterproof shoes are generally composed of a non-waterproof outer upper and an inner shoe lining composed of a waterproof liner. In order to ensure the waterproofness of the waterproof liner, the needle car can only drive the upper part of it, so that in most parts, the outer upper and ...

AI Technical Summary

Problems solved by technology

[0006] (1) The lower edge of the upper is severely wrinkled after climbing, and it is difficult to block the ubiquitous pores even with glue;

[0007] (2) At the bottom joint, there is always a non-waterproof upper layer in the middle at the junction of the waterproof and moisture-permeable membrane of the upper and the waterproof gasket, so that the two waterproof materials cannot be directly contacted to form a sealed closure;

[0008] (3) There is no way to test whether the waterproof membrane has been damaged in the previous production process, and whether the process of brushing glue and adding waterproof gasket (GASKET) has completely blocked the gap between the lower edge of the upper and the midsole. porosity, so there is no certainty about the waterproof performance of waterproof shoes, and the element of luck is very large
