Novel protective shoe upper and production technique thereof

Abstract

A process for manufacturing a novel protective shoe upper comprises the following steps: adding a processing adjuvant, a bridging agent, a foaming agent, an active agent, and pigment in EVA raw materials, forming EVA foaming body after fully mixing, finally cutting into an EVA foaming body layer; covering a bonding layer on the EVA foaming body layer, then blanking into a preset pattern modeling; placing the blanked EVA foaming body layer in a bottom die; coating a cloth-skin treatment agent on the bonding surface of the bottom layer of a shoe upper and placing on the bottom die of the die, closing a die cover, firstly pressurizing and heating and then pressurizing and cooling and fetching an end product. The protective shoe upper manufactured by the invention can effectively improve protective strength of the shoe upper, reduce collision harm from external impact force to an instep, and play a protective role for a user in outdoor activities.

Description

technical field The invention relates to a shoe upper and a manufacturing method thereof, in particular to a novel protective shoe upper and a manufacturing process of the shoe upper. Background technique For now, the uppers of traditional shoes are generally made of materials such as nylon, polyester, foam, leather or cotton textiles, and the manufacturing process is generally made by stitching single or multiple materials or hot pressing with high-frequency molds. . However, when the user is doing outdoor activities, the upper of the shoe will inevitably encounter hard objects such as mountain gravel, dead branches of shrubs, etc. The upper of traditional shoes does not have the function of rebounding external impact protection, which will cause damage to the shoe body, or even damage the It reaches the instep, which brings troubles to the user in outdoor activities.
