Problems solved by technology

[0003] There are usually two types of dyeing methods, one is inorganic dyeing method: such as using the strong oxidative properties of potassium permanganate solution as a dye to dye pearls into golden yellow to brown, but the conditions are difficult to control, and it is a little careless. It will destroy the surface of the pearl, which is quite difficult to operate in practice, and the color is relatively light, dark and dull; in addition, most inorganic dyes are not strong in binding to the surface of the pearl, which can easily cause it to fall off on the surface of the pearl. The application on the surface of gem-grade pearls; the second type is direct dyeing with organic dyes, the method is simple, and at the same time it can achieve the effect of full and bright color and uniform dyeing; but this type of dyed beads is easy to fade, and the color fastness is very poor. Easy to fade inside

Abstract

The invention relates to a dyeing method of a peal, which includes the preparation of a staining agent, the pretreatment of a peal and the dyeing the peal. Firstly, pretreatment is carried out to the staining agent and the peal to lead the bonding force between the staining agent and the peal to be greatly improved and simultaneously the peal is not damaged, thus ensuring that the peal is not easy to fade in a short time and improving the luster of the peal thereby promoting the level of the peal. Furthermore, the dyeing fluid of the peal can be repeatedly used for once or twice, thus decreasing cost and reducing pollution.

Description

(1) Technical field [0001] The invention relates to a pearl dyeing method. (2) Background technology [0002] People around the world have different preferences for the color of pearls. For example, Americans generally like white pearls with pink hues, Indians like golden yellow pearls, and Turks like blue or green pearls. At present, more than 90% of pearls need to be processed after harvesting to increase their economic value. After proper processing and coloring, pearls can be significantly improved in terms of iridescence, brightness, fullness, etc., giving people a sense of sparkling pearls and dazzling crystals. Therefore, pearl coloring plays an important role in pearl processing. However, since pearl itself is a relatively delicate gemstone, the application of many processing technologies is restricted, and it is difficult to increase the value of pearl to a large extent. At present, in the post-processing of pearls, in order to make the color uniform or meet the r...
