Abstract
The invention discloses a method for processing colorized pearls. The method comprises the following steps of: extracting a dye yam coloring matter which takes tannin, anthocyanin, saponin and the like as main components from dye yam; and dying pearls by taking distilled water as a solvent. In the conventional chemical pearl dying method, dyestuffs used for dying are basically organically synthesized chemical dyestuffs, potential problems of the compatibility and security with a human body exist. A dying material adopted in the dying process of the method is pure natural, is not required to be added with any surfactant, has a certain bacteriostatic action, and has the characteristics of human body compatibility and security; and compared with chemical dying, the method has the advantages that: the dying time is shortened, and the dying cost is lowered.
Description
Technical field
The present invention relates to a kind of processing method of pearl manufacture field, particularly a kind of colored pearl.
Background technology
The color of pearl is one of key factor of its quality of decision.Pearl all increases significantly at aspects such as iridescence, brightness, richness after appropriate colouring, gives that pearly-lustre sparkles, sparkling and crystal-clear brilliant sense, the more important thing is and will have a sudden rise in social status, and has created high added value.Therefore, the painted optimization in the processing processing pearl of pearl occupies critical role.How to make the pearl color rich and varied, pearl products is novel and diversified, has become the problem that enjoys pearl merchant and related scientific research worker and even pearl culture family to pay close attention in recent years.
The approach that obtains the colored pearl of different colours mainly is that pearl is painted.At present pearl painted mainly contain by dyeing, protein denaturation change colour, method such as radio isotope changes colour, Co60 irradiation changes colour.Yet all there is different defectives in existing pearl method of colouring.Used dyestuff substantially all is the chemical dye of organic synthesis in the chemical stain, with compatibility, the security of human body all be a potential problem, and the organic reagents such as benzene, methyl alcohol that use in the dyeing course more, like this, one is to cause to the pollution of environment with to the influence of operator ' s health in process, also may have potential harm to wearing human body simultaneously.
Therefore, select for use natural colouring matter, will play positive impetus the development that promotes China's pearl sector to the pearl processing of dyeing.
Summary of the invention
The invention provides a kind of processing method of colored pearl, utilize natural dye yam pigment to give dyeing pearl, solved the defective that prior art exists, having satisfied at present, people pursue the life idea of nature, environmental protection, health.
The technical scheme that the present invention takes may further comprise the steps: preparation dye yam pigment; Pearl is after punching, bleaching pre-treatment, and placing concentration with distilled water preparation is 2%～5% dye yam pigment solution; 35～40 ℃ of water-baths were dyeed 3～15 days; Pearl after the dyeing is cleaned with 35～40 ℃ distilled water, removes surperficial loose colour; Put pearl into drying box inherence 30～35 ℃ of dryings.
The preparation method of above-mentioned dye yam pigment is after dried dye yam stem tuber is smashed, and crosses 100 sieve meshes, and the pulverizing sample dissolution of getting 8～12g was flooded 5～6 hours down at 50～30 ℃ in 60% aqueous acetone solution of 100ml, got filtrate; Concentrate recovery acetone with maceration extract, continue the dipping residue after 3～4 hours suction filtration discard filter residue, merging filtrate, rotary evaporation in vacuo concentrates in 70～80 ℃ of water-baths, remove and reclaim solvent, obtain paste, paste delivered to removed most of liquid in the air dry oven and be placed on 30～35 ℃ of dryings of vacuum desiccator, brown ceramic powder be the dye yam pigment.
Compared with prior art, major advantage of the present invention is: adopt pure natural plant pigment dyeing pearl, do not have artificial chemical adding ingredient, and strong with the human body compatibility, and have certain bacteriostasis, have technology characteristics simple, with low cost simultaneously.
The specific embodiment
Below in conjunction with embodiment the preparation method of colored pearl is described further.
1) the dye yam pigment prepares: after dried dye yam stem tuber is smashed, cross 100 sieve meshes, get the powder essence sample that sieves, the pulverizing sample dissolution of getting 10g is in 60% aqueous acetone solution of 100ml, flooded 5 hours down at 60 ℃, suction filtration after the lixiviate, get filtrate, (acetone that concentrate to reclaim with maceration extract with residue refluxing extraction after 3 hours suction filtration) discards filter residue, merging filtrate, and rotary evaporation in vacuo concentrates in 80 ℃ of water-baths, remove and reclaim solvent, paste, paste delivered to removes most of liquid in the air dry oven and be placed on 35 ℃ of dryings of vacuum desiccator, brown ceramic powder be the dye yam pigment.
2) pearl is carried out pre-treatments such as sorting, punching and bleaching.
3) dye liquor preparation: with the dye yam pigment solution of distilled water preparation 2%.
4) dyeing pearl: pearl is immersed in the dye liquor, is advisable with firm submergence pearl, 40 ℃ of water-baths were dyeed 3～7 days, with dyeing time lengthening, pearl color burn.
5) pearl after the dyeing is with the cleaning of 35～40 ℃ distilled water, is drying to obtain the light brown pearl after removing surperficial loose colour under 35 ℃.
Claims (2)
1. the processing method of a colored pearl may further comprise the steps: preparation dye yam pigment; Pearl is after punching, bleaching pre-treatment, and placing concentration with distilled water preparation is 2%～5% dye yam pigment solution; 35～40 ℃ of water-baths were dyeed 3～15 days; Pearl after the dyeing is cleaned with 35～40 ℃ distilled water, removes surperficial loose colour; Put pearl into drying box inherence 30～35 ℃ of dryings.
