Abstract

A method for dyeing pearl to increase its metallic luster includes such steps as preparing diluted ammonia water containing copper sulfate, putting pearl in it, reacting at 40-70 deg.C for 2-10 days, washing and drying.

Description

(1) Technical field [0001] The invention relates to a pearl dyeing method. (2) Background technology [0002] In recent years, many workers have carried out research on the dyeing treatment technology of pearls. For example: using direct dyes and disperse dyes dissolved in solvents such as methanol, ethanol, acetone, DMF, etc., under the action of penetrants, dispersants and other additives, they penetrate into the pores of the inner and outer layers of pearls, so that pearls are directly dyed and developed. The disadvantage is that the dye is simply adsorbed in the pearl, which is easy to fade (change) color, and the dye is easily soluble in organic solvents, and the wet fastness is particularly poor; there are also reactive dyes, although it can improve the dye and pearl. The color fastness is also significantly improved, but the organic dye itself will fade (change) after being oxidized for a long time; there is also the use of radioactive isotopes such as cobalt 60 to d...
