Environment-friendly cushioning good-enwrapping performance popcorn-like bridging shoe and making technology thereof

Abstract

The invention relates to an environment-friendly cushioning good-enwrapping performance popcorn-like bridging shoe and a making technology thereof. An upper of the bridged shoe consists of an inner boot and a vamp; the inner boot is formed by integrally connecting an inner lining, and an inner cushion formed through once injection moulding; the neckline of the inner boot is fixedly connected with the neckline of the vamp; the lower edge of the vamp stretches to the bottom surface of the inner cushion and is fixedly connected with the inner cushion; the upper and a sole are integrally connected through a PU bridging layer; the PU bridging layer enwraps the lower edge of the vamp; the sole is a popcorn-like sole made by mixing PU and TPU popcorn granules. Compared with the conventional shoemaking technology, the making technology provided by the invention has the advantages as follows: the making technology is relatively simple, a sole laying process and an insole assembling process can be omitted, the popcorn-like sole and the bridging layer are bonded more firmly, and the shock absorbing performance is better; through the inner boot designed and made according to a foot shape, the upper and the sole can enwrap a foot well; by increasing the using amount of a PU material, the environment-friendly cushioning good-enwrapping performance popcorn-like bridging shoe is higher in soluble ratio and more environment-friendly.

Description

technical field [0001] The invention relates to a bridge-building shoe and a production process thereof, in particular to an environment-friendly popcorn bridge-building shoe with good cushioning and wrapping properties and a production process thereof. Background technique [0002] At present, sports shoes on the market are equipped with insoles. At present, the top surface of most insoles is flat, which is difficult to fit the soles of the feet, and the wearing comfort is not ideal; although the upper surface of some insoles is designed as a concave structure that fits well with the soles of the feet , but the fitting degree of such a sole is still difficult to achieve a good state, and because the insole and the upper are separate structures, there will be a certain angle at the junction of the edge of the insole and the upper, and this part is difficult to fit the foot. The mobility of the insole caused by the overall structure makes it difficult for the insole to remain...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a kind of popcorn bridge-building shoes with good environment-friendly shock-absorbing wrapping property, so as to overcome the problem that the wrapping property of the vamp face and the foot is difficult to reach a good state in most existing shoes, and the environmental protection of the shoes is not ideal.
