WIPO Patent Application WO/2023/125193

A1

The present application relates to the technical field of household appliance panels. Disclosed is a preparation method for a dyed panel, comprising: coating a pre-dyed surface of an original sheet with a UV adhesive layer, and curing same; vertically placing the original sheet above a main dyeing tank, and letting a dye uniformly flowing from bottom to top in the main dyeing tank; and controlling the original sheet to gradually descend, in a repeated inching manner, in the dye in the main dyeing tank so as to dip dye the pre-dyed surface with the dye to obtain a dyed panel. The original sheet gradually descends, in a repeated inching manner, in the dye flowing uniformly from bottom to top, so that the UV adhesive layer on the pre-dyed surface is dynamically and uniformly dip-dyed with the dye, the dyeing effect is more natural, the pre-dyed surface has excellent light transmittance, and sufficient dip dyeing is achieved, reducing the probability of an invalid area with uneven dip dyeing. Further disclosed in the embodiment of the disclosure is a dyed panel.
