Title:
LIGHT-TRANSMITTANCE ARTIFICIAL LEATHER AND MANUFACTURING METHOD THEREFOR, LAMINATING LEATHER, AND AUTOMOTIVE INTERIOR
Document Type and Number:
WIPO Patent Application WO/2021/195866
Kind Code:
A1
Abstract:
A light-transmittance artificial leather and a manufacturing method therefor, a laminating leather, and an automotive interior. The light-transmittance artificial leather comprises a surface treating agent layer and stacked multilayer polymer material layers. The multilayer polymer material layers at least comprise a surface layer, the surface layer is a colored layer, and the surface treating agent layer is attached to the surface layer. The light-transmittance artificial leather further comprises a light shielding layer, a hollow or light-transmittance structure is provided on the light shielding layer, and the light shielding layer is provided between two adjacent polymer material layers. According to the light-transmittance artificial leather, the light shielding layer is directly provided between the polymer material layers, and the hollow structure is provided on the light shielding layer, so that a pattern formed by the hollow structure can be presented on the surface of the light-transmittance artificial leather by providing a light source at the hollow structure, thus a pattern that is desired to be presented can be obtained without providing a specific shape of light source, and a very clear pattern can be obtained even in a laminating leather structure.
