Patent ID: 10747019

Abstract:
A method for fabricating a multi-color cellulose acetate spectacle frame, which includes: baking a multi-color cellulose acetate sheet so that it is soften; pressing so as to enable the second, third, and fourth color layers of the multi-color cellulose acetate sheet to move a distance greater than the thickness of a surface color layer of the multi-color cellulose acetate sheet; grinding off or shaving off a surface layer of the excessively moved portion so that the color of a middle layer is highlighted; baking the multi-color cellulose acetate sheet again so that it is soften; pressing so that the color of the middle layer is highlighted to the surface of the spectacle frame. According to the method for fabricating the multi-color cellulose acetate spectacle frame, the working processes are saved, and the qualification rate of product is improved.
