Leather and printing device and method thereof

Abstract

The invention discloses leather and a printing device and method thereof and relates to the technical field of leather. The leather comprises a base material and one or more resin layers. The base material is composited with the one or more resin layers, and a plurality of micro holes are formed in the resin layers. Patterns are arranged on the positions, away from the base material, of the surfaces of the resin layers and formed in a corroded mode through corrosive liquid. The portion, corroded by the corrosive liquid, of the surface of the leather forms a miniature convex-concave structure and corroded into the various patterns, and the diversified visual effect is brought to people. In the corrosion process, the micro holes of the leather are not damaged, large temperature change is also avoided, the air permeability of the leather is good, and the flexible degree is higher. In this way, the problems that as for leather manufactured in the prior art, the diversified visual effect cannot be brought to people, the flexible degree of the leather is decreased, and the air permeability is poor are solved.

Description

technical field [0001] The invention relates to the technical field of leather, more specifically, to a leather and its printing device and printing method. Background technique [0002] As a material, leather is widely used in the production of clothes, shoes, bags and other products. With the diversification of people's life, leather products are more and more favored by users. [0003] The surface of the leather is often made of different colors by rolling coating or spraying, and different patterns can be hot-pressed with a leather embossing machine, or textured paper can be used to make leather with textures on the surface. However, the leather obtained by the above method has a single color and texture, which cannot bring diversified visual effects to users; and, after being hot-pressed by an embossing machine, the softness of the leather decreases, and both the embossing machine and the textured paper will be damaged. The micropores on the leather surface reduce the ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of leather, which can be corroded by corrosive liquid on the surface of the leather to obtain patterns, so as to solve the problems that the leather produced in the prior art cannot give people a variety of visual effects, the softness of the leather is reduced, and the air permeability is poor
