Three-dimensional pattern layer manufacturing method for shoe upper

Abstract

The invention relates to a method for manufacturing a three-dimensional pattern layer for shoe uppers, which enables the three-dimensional pattern layer to have the functions of light weight and cushioning protection in addition to a strong three-dimensional visual effect. Steps: Make at least one screen printing board according to the design pattern; use one of the screen printing boards to screen print on the shoe surface and dry to form a water-based resin bonding layer; then silk screen and dry before the outer layer of the water-based resin bonding layer is completely dried to form Water-based foaming ink layer, the water-based foaming ink layer contains an ultraviolet light attenuator, and the surface of the water-based foaming ink layer is irradiated with ultraviolet light for 15 to 20 seconds to obtain a modified foam whose melt strength gradually decreases from the outside to the inside Ink layer; physical processing on the surface of the modified foaming ink layer to form a number of premixed concave areas, drying; then use any of the screen printing plates to screen print on the outer surface of the modified foaming ink layer and dry to form a foaming color paste layer , and the foaming color paste layer is set from the inside and the outside to form three layers of distribution and layering formed by scraping with three different proportions; molded foaming.

Description

technical field [0001] The invention relates to the technical field of footwear products, in particular to a method for manufacturing a three-dimensional pattern layer for shoe uppers. Background technique [0002] In the traditional shoe-making industry, the decorative pattern is usually printed with ink on the upper of the sports shoe, and it can only be printed on the uppermost part of the upper. It cannot be too large, the pattern design is limited, and the pattern printed with ink Flat patterns do not have support and protection functions, they can only be used for decoration, and the patterns do not have a three-dimensional effect. For this reason, someone designed to add a cotton layer or a composite cotton layer made of leather, artificial leather, etc. to make patterns on the upper of sports shoes, so as to improve the comfort of sports shoes and provide support and protection. function. However, the disadvantage of this method is that the flexibility and variabil...

Problems solved by technology

However, the disadvantage of this method is that the flexibility and variability of making patterns with cotton layers is poor, and the patterns that can be made are relatively single, which does not meet the diverse needs of modern society.

[0003] Moreover, traditional trims are heavy, and the wearer's physical energy consumption will increase by 1% for every 100 grams of sports shoes weight. The structure needs to be improved in terms of buffer protection performance
