Preparation method and colouring method.
Background technology:
Semen Euryales, also referred to as Gorgon fruit, thorn Rhizoma Nelumbinis, belong to nymphaeaceae plant, and annual aquatic and herbaceous is planted
Thing, has stimulating appetite, helps effect of air culture unit, be traditional Chinese crude drug and precious natural benefit
Product, dietotherapeutic.Being similar to Caput Gallus domesticus when Semen Euryales is in bud, root, stem, leaf, fruit all can be used as medicine, on the ground
Organ is in addition to blade back spinosity, and remainder is smooth stingless, has white fibrous root and unconspicuous stem.
The petiole of Semen Euryales, bennet can be as fresh vegetables during summer, and flower, leaf have ornamental value.Semen Euryales taste
Sweet, complex chemical composition, containing substantial amounts of protein, carbohydrate, riboflavin and other dimensions
Raw element composition, has the curative effect of supplementing the kidney to control the nocturnal, tonifying spleen and stopping diarrhea, eliminating dampness and arresting leucorrhea.
Owing to the thought of resource reclaim recycling is progressively rooted in the hearts of the people, to the seed coat of Semen Euryales, petiole, flower
The developmental research at the positions such as stalk, extracts its effective ingredient, other application of development Semen Euryales.Outside Semen Euryales
Shell and seed coat are the most all used as feedstuff, or discarded, not only waste the energy, and can pollute ring
Border, has had a small amount of research report by extracting natural dye in Semen Euryales shell and can be used for textile dye
Color.
The shell of Semen Euryales and seed coat can extract the natural dye of brown, and the seed coat of Semen Euryales contains
Single-character given name material, in shell, fatty acid and trace element also compare many, in the natural dye therefore extracted also
Possesses certain antibacterial oxidation resistance.Chinese patent CN 101775234B (publication date 2010.7.14)
The extracting method of disclosed natural dye of gordon euryale seed shell and the application in pure cotton dyeing, clean Semen Euryales shell
Clean pulverizing, through ultrasonic Treatment, ethanol extraction 2 times, decompression distillation and concentration filtrate obtains thick Semen Euryales
Hull natural dye, then after cation macroporous resin column separating-purifying, obtain brownish-yellow powder shape Semen Euryales shell
Natural dye extract, obtains knitting through the cotton textiles of natural dye of gordon euryale seed shell dyeing through direct staining technique
Thing.(natural dye of gordon euryale seed shell silk dyeing dynamics research, the pretty tinkling of pieces of jade etc. of recording, Changzhou is big for Chinese literature
Learn journal, in June, 2011, the 2nd phase of volume 23, the 24-28 page) disclosed in Semen Euryales shell natural
The dyestuff application to silk dyeing, by cleaned for Semen Euryales shell, dry, pulverizing, ethonal extraction,
Filter, be concentrated under reduced pressure to give powder natural dye, mulberry silk fiber is obtained after direct staining Gorgon euryale
The mulberry silk fiber of real hull natural dye dyeing.
From prior art, the preparation method of current natural dye of gordon euryale seed shell is similar to, and is used for attempting
In the dyeing of natural fiber, and because the natural dye of gordon euryale seed shell prepared of the method still contains
Plurality of impurities, the dyeability fluctuation of the natural fiber after dyeing is relatively big, more unstable, thus for
The preparation method of natural dye of gordon euryale seed shell remains a need for studying further, stablizes excellent in the hope of obtaining dyeability
