Problems solved by technology

[0005] At present, in the production process of pearl dyeing dyeing, the main problem is: due to the limitation of dyes and dyeing process conditions, the coloring effect of pearls is poor, and it is impossible to achieve uniform dyeing, full color and bright effect
Especially when dyeing red, the dyeing index is poor and cannot meet the market requirements. Therefore, the quality and market of pearls are greatly affected.

Abstract

The invention relates to a pearl eosin dyeing method and belongs to the technical field of pearl dyeing. The method comprises the following steps of: (1) pretreating a pearl, namely soaking the cleaned pearl in hydrogen peroxide for 12 to 24 hours, and transferring to absolute ethyl alcohol for first dehydration treatment, and changing the absolute ethyl alcohol; (2) preparing dyeing solution, namely preparing water, the absolute ethyl alcohol and absolute methanol into a solvent according to a volume ratio of 2-6:3-5:1-5, adding dyes, potassium iodide and a surfactant into the solvent and fully mixing to prepare the dyeing solution; and (3) dyeing the pearl, namely impregnating the pretreated pearl into the prepared dyeing agent, dyeing for 3 to 7 days at the constant temperature of 45 DEG C, and cleaning and drying to obtain the finished product. The pearl eosin dyeing method has the advantages of good dyeing effect, and uniform and bright dyed red color.

Description

Technical field: [0001] The invention relates to a pearl eosin dyeing method, which belongs to the technical field of pearl dyeing. Background technique: [0002] Pearl is a kind of precious aquatic product. It is not only a kind of precious medicinal material, but also has the effects of calming nerves, calming convulsions, clearing heat and detoxification, and promoting human metabolism. It can also be used to make high-end decorations. It is an important product for export. With the increase of pearl cultivation and production in recent years, the quality problems of pearls are increasingly threatening the development of the cultivation industry. [0003] The value of pearls lies mainly in their decorative value, and they have been regarded as rare treasures since ancient times, and they are known as the "Queen of Jewels". However, due to the influence of internal and external factors during the formation of pearls, their quality varies greatly. According to statistics,...
