Problems solved by technology

When traditional shoemaking adopts the seamless process, it is necessary to pad the backing. However, in the process, there are often problems that the backing is off-track and the three-dimensional fine-graining process cannot be done. Therefore, it is very important to design a three-dimensional forming shoe upper and processing technology. Necessary

Abstract

The invention discloses a stereoscopically formed vamp and a processing technology, the stereoscopically formed vamp comprises a vamp main body, a front lining, a rear piece, eyelets, a sole edge, a decorative piece and a rear patch, the vamp main body comprises a TPU polyurethane adhesive film, a TPU closed-cell polyurethane foaming layer and a PU polyurethane layer; wherein the TPU polyurethane adhesive film, the TPU closed-cell type polyurethane foaming layer and the PU polyurethane layer are sequentially calendered and compounded from top to bottom; the processing technology comprises the following steps: 1, equipment cleaning; 2, layered manufacturing; 3, calendering and compounding; 4, subsequent processing; 5, three-dimensional forming; and 6, inspecting and storing; the vamp has the characteristics of light volume, mildew resistance, bacteria resistance, scratch resistance, tear resistance and the like; the flatness and the softness uniformity are improved by more than several times, and the vamp is super-strong, resistant to low temperature and resistant to stretching; the medium-high-low temperature seamless process is directly used for three-dimensional forming, a bottom sheet is not needed, and the tedious part of the traditional seamless process is omitted; and the vamp can also be applied to furniture, sofas and other products.

Description

technical field [0001] The invention relates to the technical field of shoemaking, in particular to a three-dimensionally formed shoe upper and a processing technique. Background technique [0002] With the continuous improvement of people's living standards, people are increasingly pursuing the quality of life, and shoes, as an indispensable daily necessities in human life, people have higher and higher requirements for them. With the popularization and development of industrialization, people have discovered many polymer materials and gradually applied them to life. When traditional shoemaking adopts the seamless process, it is necessary to pad the backing. However, in the process, there are often problems that the backing is off-track and the three-dimensional fine-graining process cannot be done. Therefore, it is very important to design a three-dimensional forming shoe upper and processing technology. Necessary. Contents of the invention [0003] The purpose of the ...
