Problems solved by technology

[0002] Existing leather products are generally black or brown or gray, with a single color, and some are embossed or painted with patterns, but the pressed patterns or painted patterns are only suitable for belts, gloves and leather-colored box leather. It will not be soft when used on clothes, and the color of the surface is monotonous, especially the lacquer pattern is easy to fall off, and it will fall off after three or four times of rubbing. The existing leather coloring cannot make the leather bright and bright. Pack aesthetically pleasing patterns and colors

Embodiment approach

[0066] Here is a specific explanation for the plate maker, taking the coloring process of goat clothing leather as an example:

[0067] 1. Plate making:

[0068] Use ∮3 iron wire woven well-shaped screen as the bottom net, the grid is 1.5×1.5 (cm) squares, the maple leaves collected from maple trees are arranged on the top, and the top is covered with a fastening net made of nylon screens. Tighten the two layers of grid on the wooden frame around the net, make the two layers close and keep the grid surface flat, and make a spray pattern with the bottom grid and maple leaves as the pattern.

[0069] 2. Coloring process:

[0070] 1. Preparation of finishing agent, brightener and curing agent
