Abstract
The invention discloses a production technology of high-purity plant indigo dye, which includes the following steps: plant bluegrass is first treated by calcium hydroxide or calcic oxide in an indigo fermentation vat so as to obtain the initial plant indigo dye, which is then mixed with water, and subsequently the mixture is added with acid and heated to 30-120 DEG C, with the temperature preserved for 10-200min, then the solution is added with a drug with strong basicity, and in succession, boiled for 10-200min, filtered and washed in water for a plurality of times and finally dried and pulverized into powder to obtain the high-purity plant indigo dye. The high-purity plant indigo dye produced by the technology that is environment-friendly is powder-shaped, convenient for transportation, has the strength of over 100 times of that of unimproved dye and reliably ensures the evenness and redyeing property of the dye owing to the basically removal of impurities.
Description
Technical field
The present invention relates to a kind of production technique of vegetable dye.
Background technology
Traditional vegetable indigo production technique is that the juice under receipts are cut does not lose bluegrass to be positioned over the system of macerating of carrying out certain hour in the fermentation vat (different with conditions such as regions according to temperature, generally macerating the system time is 1～10 day) so that indigo glycoside generation hydrolysis (hydrolysate is water-fast indigo and monose) in the bluegrass.After having fermented, with proper implements the rotten branch in the fermentation vat is pulled out, and the liquid in the fermentation vat is impacted 1～10 hour continuously with stamp pestle; Then inject the liming that configures in the pond, do not stop to stir, the water color presents yolk yellow up to the pond; Leave standstill 8～20 hours then, and after emitting water in the fermentation vat step by step, obtain traditional indigo plant dyestuff, tradition system indigo figure as shown in Figure 1.
In above-mentioned technology, the traditional plant bipseudoindoxyl dye of preparation becomes colloid mud shape, it is inconvenient to transport and separates out deposition easily, in use be difficult to demarcate the quantity of at every turn taking, add lime carbonate a large amount of in the vegetable indigo, pectin, wax and the ash impurity that grades, cause vegetable indigo dye power part low excessively, the neither suitable need of industrial production of above-mentioned all disadvantages.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of production technique of high-purity vegetable indigo dye of suitable suitability for industrialized production needs, and the vegetable indigo dye convenient transportation of preparation is easy to use and have enough power parts.
In order to solve the problems of the technologies described above, the production technique of high-purity vegetable indigo dye of the present invention, described production technique may further comprise the steps:
The oxide process of A. the plant bluegrass being passed through calcium hydroxide or calcium in indigo fermentation vat obtains the original plant bipseudoindoxyl dye;
B. the original plant bipseudoindoxyl dye is mixed with water, then add acid and be heated to 30 °～120 °, be incubated 10～200 minutes;
C. adding has alkaline medicine, then boils and boils 10～200 minutes;
D. carry out several times suction filtration, washing, at last through super-dry with become powder to obtain described high-purity vegetable indigo dye.
As improvement of the technical scheme, described acid is acid organic acid or the mineral acid stronger than carbonic acid, is preferably hydrochloric acid.
As further improvement in the technical proposal, add in the sour process among the step B and also need continuous stirring.
Need carry out several times washing, suction filtration between step B and the step C.
The invention has the beneficial effects as follows: adopt the high-purity vegetable indigo dye of above-mentioned explained hereafter to become powder shaped, convenient transportation, the dyestuff power part that makes is more than 100 times of dyestuff power part before improving, production technique environmental protection simultaneously; Because impurity is removed substantially, the level-dyeing property of dyestuff and redying property have had reliable assurance, prepared natural indigo plant dyestuff powder has medicinal value of very high broad-spectrum antimicrobial and uvioresistant performance, so can develop the functional of high added value and germ resistance healthcare face fabric.
