Abstract

The invention relates to the technical field of mobile phone rear covers, in particular to a technology for producing a color gradually-changed mobile phone rear cover. The technology includes the following steps that (1) cutting is conducted; (2) LOGO printing is performed; (3) UV transfer printing is carried out; (4) dip dyeing is conducted, colorful printing ink is used for dip dyeing of a pattern layer to form a color gradually-changed layer, and the dip dyeing temperature is 80-90 DEG C; (5) electroplating is performed; (6) a cover bottom is printed; (7) high-pressure treatment is carriedout; (8) strengthening is performed and (9) CNC cutting is executed. Dip dyeing is also called exhaustion dyeing, belongs to a dye application term and involves a method in which a dyed material is dipped into a dye bath containing dye and required auxiliaries and the dyed material is gradually dyed by the dye through dye bath circulation or dyed material movement. The method is also a dyeing method of repeatedly dipping the material into dye liquor to make the material and the dye liquor be relatively moved continuously. By adoption of the technology for achieving color gradual changing withdip dyeing, dip-dyed products are evenly colored, and the gradual changing effect is good; and moreover, various colors can be dip-dyed at the same time.

Description

technical field [0001] The invention relates to the technical field of mobile phone back covers, in particular to a production process for gradient color mobile phone back covers. Background technique [0002] In today's ever-expanding mobile phone market, the competition in the processing of mobile phone back covers is also intensifying, and the appearance requirements of mobile phone back covers are becoming more and more diverse. The existing production process of gradient color mobile phone back cover mostly adopts the method of printing translucent color to produce gradient color products, but the printed products will have obvious color layering, and the gradient effect is poor.
