Abstract
The invention relates to a Vaccinium bracteatum Thunb. plant dye extraction method. The method comprises the following steps of collecting Vaccinium bracteatum Thunb. Leaves, removing stems and other impurities, carrying out drying in the shade, carrying out crushing, immersing the crushed Vaccinium bracteatum Thunb. Leaves in deionized water according to a bath ratio of 1: 10-20 at a temperature of 10-20 DEG C for 24-48h, carrying out filtration to remove residue, and carrying out vacuum condensation on the filtrate so that the Vaccinium bracteatum Thunb. plant dye is obtained. The Vaccinium bracteatum Thunb. plant dye does not contain any toxic chemical agent, is a natural pigment extracted from plants and is environmentally friendly, and the residue obtained by extraction can be degraded naturally, can be used as natural fertilizer after simple treatment and does not produce any pollution on the environment so that a good application prospect is realized.
Description
Technical field
The invention belongs to field of plant dye, particularly a kind of extracting process of Fructus Vaccinii Bracteati vegetable dye.
Background technology
Fructus Vaccinii Bracteati, has another name called south candle, and ancient title contaminates bean.Belong to Ericaceae evergreen shrubs, be distributed in south China area more.Because of people have its leaf of the annual lunar calendar junior three in March steam black food with and gain the name.Happiness light, drought-enduring, cold-resistant, barren-resistant, Bioclimatic analysis comparatively extensively, all can plant by China's most area.Myrtillin leave is put down, lightly seasoned, there is the function that improving eyesight crow sends out, include a large amount of blue-black pigment, its chromophoric group is indigoid and chroman chroman, the pigment content of Fructus Vaccinii Bracteati fruit is also very high, in dark red to blue, its chromophoric group is Anthraquinones and indigoid, experiment proves, not only food dye can be used as by the natural pigment of special process extraction, process for textile dyeing, also good effect can be obtained, the soft nature of color and luster, every fastness all can meet the requirement of textiles general fastness, be widely used in infant article, underskirt, bedclothes etc. spin in family, safety and environmental protection.
In recent years along with the day by day in short supply of petroleum resources and synthetic chemistry dyeing are endangering healthy the replacing of people, to the severe contamination of ecotope, more and more by society is paid attention to, the flower of plant taken from by vegetable dye, the natural pigment really, in stem, seed, skin forms, nontoxic, harmless, extract after residue can natural degradation, compatible with bad border, meet the theory of cleaner production, the new power promoting textile industry Sustainable development must be become.
Now known vegetable dye coloured light mostly is redness, yellow, grey, blueness etc., myrtillin leave through extraction after pigment content high, in black-and-blue, just in time can make up this shade vacancy, enrich chromatogram content.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of extracting process of Fructus Vaccinii Bracteati vegetable dye, the method does not add any toxic chemical medicament, take from natural pigment in plant, environmental protection, residue energy natural degradation after extracting, after simple process, can be used as Natural fertilizers, any pollution is not caused to ecotope, has a good application prospect.
The extracting process of a kind of Fructus Vaccinii Bracteati vegetable dye of the present invention, comprising:
Gather myrtillin leave, remove stem and other impurity, dry in the shade, broken; Soak 24 ~ 48 hours with at deionized water 10 DEG C ~ 20 DEG C by bath raio 1:10 ~ 20, filter and remove residue, filter vacuum is concentrated, obtains Fructus Vaccinii Bracteati vegetable dye.
It is broken that crusher is put in described fragmentation.
Describedly be broken into 1cm × 1cm.
Described filtration adopts absorbent gauze to filter.
Described Fructus Vaccinii Bracteati vegetable dye is used for all-cotton knitting dyeing fabric, and concrete steps are as follows: prepare grey cloth, stirs Fructus Vaccinii Bracteati vegetable dye with the warm water of 2 times, heats up and dyes, with after through washing, dehydration, oven dry heat setting type.
Described temperature-rise period, for rise to 35 DEG C with 1 DEG C/min, keeps 15min, rises to 80 DEG C with 1.5 DEG C/min, keeps 30min.
beneficial effect
Fructus Vaccinii Bracteati vegetable dye of the present invention uses water as solvent carries out immersion extraction form leaf, stem, without the need to adding any chemical agent, the residual branch of the plant after extraction, residual leaf can natural degradation even can as fertilizer; Environmental protection, the residue energy natural degradation after extracting, can be used as Natural fertilizers, does not cause any pollution, have a good application prospect to ecotope after simple process.
Accompanying drawing explanation
Fig. 1 is the schema of vegetable dye of the present invention for dyeing.
