Problems solved by technology

At present, the temperature-sensitive color-changing leather on the market, because the color-changing material added to the artificial leather is prone to uneven dispersion, resulting in color unevenness such as color spots in the temperature-sensitive color-changing leather, which affects the quality of the product
In addition, in the production process of thermochromic leather, due to the complicated preparation process, the production cost of thermochromic leather is relatively high.

Embodiment 1

[0026] This embodiment provides a thermochromic leather, which includes a leather base layer, and the leather base layer can be selected from animal leather or artificial leather. The leather base layer is provided with a ground color layer, and is pressed on the leather base layer with a mold that has been opened. According to the color of the ground color layer that is actually required, a layer of ground color layer is printed manually or printed with a computer, and the ground color layer is used to cover the leather The base layer is completely covered, and the original color of the leather base layer cannot be exposed.

[0027] An isolation layer is arranged on the base color layer, and the isolation layer is an isolation varnish, which plays an isolation role on the base color layer. A thermochromic layer is provided on the isolation layer, and the color of the thermochromic layer changes with temperature, showing different colors. The thermochromic layer includes the ...

Abstract

The invention belongs to the technical field of leather, and discloses thermochromic leather as well as a production method and application thereof. The thermochromic leather comprises a leather baselayer, a ground color layer is arranged on the leather base layer, an isolation layer is arranged on the ground color layer, and a thermochromic layer is arranged on the isolation layer. According tothe thermochromic leather, the ground color layer can be coated with a color required by a user, the isolation layer can prevent the color of the ground color layer from floating upwards and can prevent the color of the thermochromic layer from permeating downwards, and the thermochromic layer can show different colors along with the change of the temperature. The thermochromic leather has the advantages of being stable in performance, uniform in color change and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of leather, and in particular relates to a thermochromic leather and its production method and application. Background technique [0002] Color-changing leather refers to artificial leather that will produce color-changing effects under changes in temperature or pressure, including stress-changing leather and thermochromic leather. Stress color-changing leather is made of a new type of color-changing resin and a specific process technology. When it is stretched, jacked up, bent, folded and other external stresses, the deformed part of the artificial leather will show color Changes, and with the change of deformation gradient, the color presents a gradient feature from light to dark, which can give people a natural and soft feeling. Once the external force is removed, the color of the leather will naturally return to its original state. The current stress-changing leather is usually made of stress-changing ...
