Abstract
The invention discloses a preparation method and application of natural dye of water caltrop shell thereof. The water caltrop shell is smashed and then is added into 5 times to 10 times of aqueous solution to be dipped; after the water caltrop shell is fully wetted, sodium hydroxide, sodium carbonate or sodium phosphate is added until the pH of the solution is adjusted to be 8 to 13; the temperature is raised to be between 90 DEG C and 100 DEG C and then is kept for 60 minutes to 90 minutes; the solution is filtered; the filter residue is continuously dipped, extracted and filtered with the alkali solution with the pH of 8 to 13; the solution after two times of dipping and extraction is combined to prepare the stock solution of the natural dye; the stock solution is contracted, solidified and smashed to prepare the natural dye of powder shape. No mordant, mixed rare earth chloride, metal aluminum salt or metal ferrous salt is used for dying products of natural silk or wool. First cation modifier is used for modification; then the natural dye of water caltrop shell is used for dying cotton products. The invention has the advantages of the simple process, the high efficiency, the stable quality and the broad market prospects.
Description
Technical field
The present invention relates to natural dyestuff and application thereof, particularly relate to a kind of preparation method and application thereof of water chestnut hull natural dye.
Background technology
Along with the continuous enhancing of human environmental consciousness and to the growing interest of self health, the partial synthesis dyestuff is more and more noticeable to the harm that human health and ecotope are produced.Existing result of study shows have 23 kinds of carcinogenic aromatic amines, more than 100 synthetic dyestuff might produce carcinogenic substance, and more than 20 synthetic dyestuff produce irritated to skin.Therefore, synthetic dyestuff and painted textiles thereof are suspected the human consumer.
Water caltrop, another name water water caltrop, wind water chestnut are Trapaceae water chestnut platymiscium, are annual aquatic woody plants, originate in the warm area in Europe and Asia, at the cultivation history in existing more than 3000 year of China, the about 40000hm of China's cultivated area at present
2, about 240,000 tons of annual production.The fruit of water caltrop is edible, has very high nutritive value, and the carpopodium of water caltrop, fruit and petiole all can be used as medicine.
But the traditional Chinese medical science is thought water caltrop invigorating the spleen, diuresis, the only dysentery that can be good for the stomach also, and is anticancer, cures mainly stomach ulcer, dysentery, esophagus cancer, cervical cancer, mammary cancer etc.The water caltrop shell can be controlled diarrhoea, prolapse of the anus, hemorrhoid, yellow water disease, pemphigus, and water caltrop shell water extract has the effect that suppresses stomach cancer cell.
A large amount of water caltrop shells are discarded, and are very unfortunate, and can cause environmental pollution yet under normal conditions.Therefore, from the water caltrop shell, extract natural dyestuff and be applied to textile dyeing,, reduce cost of dye for increasing natural dyestuff kind and chromatogram, China is the Eleventh Five-Year Plan period developed a circular economy, and building a resource-conserving and environment-friendly society has crucial meaning.
About the preparation and the dyeing process thereof of water chestnut hull natural dye, not seeing at present has report.
Summary of the invention
The purpose of this invention is to provide a kind of preparation method and application thereof of water chestnut hull natural dye, is raw material with the water caltrop shell, adopts processing methodes such as alkaline aqueous solution extracts, concentrates, curing, pulverizing to be prepared from natural dyestuff.
The technical solution adopted for the present invention to solve the technical problems is:
One, a kind of preparation method of water chestnut hull natural dye, the step of this method is as follows:
1) with plant water caltrop shell mechanical disintegration, join then in 5～10 times of aqueous solution and soak, treat that the water caltrop shell is fully wetting after, add sodium hydroxide, yellow soda ash or sodium phosphate, the pH of regulator solution is 8～13, is warming up to 90～100 ℃, insulation 60～90min filters; It is 8～13 alkaline solution lixiviate that filter residue continues with pH, filters, and merges vat liquor twice, must natural dyestuff stoste;
2) the water chestnut hull natural dye stoste of extracting is concentrated, solidifies, pulverizes, get Powdered natural dyestuff.Two, a kind of application of water chestnut hull natural dye:
1) under the condition without mordant, the real silk, the wool product that adopt water chestnut hull natural dye can dye cream-colouredly;
2) under mordant dyeing condition after the metallic aluminium salt, can dye cream-colouredly real silk, the wool product of (band gold-tinted);
3) under mordant dyeing condition behind the metal ferrous salt, can dye atroceruleous real silk, wool product;
4) under mordant dyeing condition behind the mixed chlorinated rare earth, can dye cream-colouredly real silk, the wool product of (band ruddiness).
5) cotton products earlier carry out modification with cation modifier, the cotton products that the back adopts water chestnut hull natural dye dyeing can dye brownly, and then carry out mordant dyeing as mordant with the metal ferrous salt, obtain atroceruleous cotton products.
The beneficial effect that the present invention has is:
1, utilize waste to extract natural dyestuff, favourable protection environment economizes on resources.
2, dyeing articles is taken safety, does not have carcinogenic, teratogenesis or causes allergic reaction; Good, biodegradable with the ecotope consistency.
3, real silk, wool and the cotton products Dry Sack is even, colour fastness good can obtain cream-coloured, the red shade cream-coloured isochromatic spectrum of navy, band gold-tinted respectively under different mordant effect such as metal ferrous salt, aluminium salt, mixed chlorinated rare earth.
4, compare with conventional natural dyestuff, extraction process of the present invention is simple, the extraction efficiency height, and cost is low, and market outlook are wide.
