Abstract
The invention discloses a preparation method of giant knotweed natural dye, and the application method thereof. Firstly the giant knotweed is crushed, under the condition of 5 to 20 times of alkali solution (sodium hydroxide, sodium carbonate, sodium phosphate or sodium silicate) with pH value of 8 to 12, is lixiviated for 60 to 90 min at 95 to 100 DEG C, and then is filtered to obtain the natural dye stock solution; the natural dye stock solution is concentrated, solidified and crushed to obtain powdery natural dye. The giant knotweed natural dye can adopt the pre-mordant and post-mordant dyeing methods for dyeing, and has good dyeing effect to protein, cellulose, polyamide fiber, yarns or fabrics. The invention extracts the natural dye from the plant giant knotweed, thus the preparation process cannot cause the environmental pollution; the fabrics after being dyed are secure for wearing, and cannot cause cancer, carcinogenicity or allergic reaction; the natural dye has good compatibility with the ecological environment, and biodegradation can performed to the natural dye; the giant knotweed raw material is abundant, the price is low, the dye extraction process is simple, the quality is stable, and the market prospect is very broad.
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 giant knotweed rhizome 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.And natural dyestuff and ecotope consistency are good, and be biodegradable; The natural dye dying fabric is worn safety, and except that the dyeing function, the part natural dyestuff also has the medicinal health-care function.Advocate current people under the tide impact of green consumption product, in fields such as high grade true silk goods, health-care underclothes, home textile product, adornment, have vast potential for future development.
Giant knotweed is the perennial shrub shape of a polygonaceae herbaceous plant, often is grown in dark moist places such as height above sea level 2500m following gully, small stream limit, river bank, hillside and sylvan life, mainly is distributed in ground such as various places and Shaanxi, Hubei and Sichuan on the south China the Changjiang river.Mildly bitter flavor, cold nature has diffusing stasis of blood analgesic therapy, expelling wind and removing dampness, an effect such as reduce phlegm of quenching the thirst.The main chemical compositions of giant knotweed is anthraquinone class, diphenylethylene, naphthoquinones class and flavonoid compound, and wherein anthraquinone derivatives such as Schuttgelb has anti-inflammatory, bacteriostatic action.The giant knotweed pigment is heat-resisting, fast light, and maximum absorption wavelength can be used as yellow natural dyestuff about 430nm.
ZL01138072.1 discloses a kind of preparation method of vegetable dye.Its main method is that " choose the plant material that contains natural pigment, add water or solvent utilization after the pulverizing and coagulate stream pipe boiling-off extraction self colour dye solution, the temperature of extracting dyestuff during boiling-off is 30～100 ℃, and the ratio of plant material and water or solvent is 1: 5-10; The described plant material that contains natural pigment is shizandra berry or Flos Celosiae Cristatae, Root of Pubescent Holly, akebi, river wood mortar, duck head grass, Philippine Violet Herb, the bark of ash, Pueraria lobota, peppermint, orange, giant knotweed ".Because the extraction process condition is carried out in neutral aqueous solution or solvent, therefore, extraction efficiency is low, dye preparations cost height.
Summary of the invention
In order to overcome the weak point that background technology exists, the purpose of this invention is to provide a kind of preparation and application method thereof of giant knotweed rhizome natural dye, be raw material with the giant knotweed, adopt that alkaline aqueous solution extracts, concentrates, curing, disintegrating process method is prepared from natural dyestuff.
The technical solution adopted for the present invention to solve the technical problems is:
One, a kind of preparation of giant knotweed rhizome natural dye
The step of this method is as follows:
1) with the plant polygonum cuspidatum mechanical disintegration, join then in 5～20 times of aqueous solution and soak, treat that giant knotweed is fully wetting after, add sodium hydroxide, yellow soda ash, water glass or sodium phosphate, the pH of regulator solution is 8～12, is warming up to 95～100 ℃, insulation 60～90min filters; It is 8～12 alkaline solution lixiviate that filter residue continues with pH, filters, and merges vat liquor twice, must natural dyestuff stoste;
2) the natural dyestuff stoste of extracting is concentrated, solidifies, pulverizes, promptly get Powdered natural dyestuff.
Two, a kind of application of giant knotweed rhizome natural dye
1. to protein, Mierocrystalline cellulose, nylon fibre, it is as follows that yarn or fabric carry out the painted step of pre-matchmaker:
1) pollutant is immersed in the water, make it fully wetting, take out then and extract, stand-by;
2) with Fe
2+, Fe
3+, Al
3+, the salt of mishmetal or its two kinds of mixtures are as mordant, concentration is 0.1～10% of pollutant weight, under 40～80 ℃ of temperature, bath raio 1: 20～50 is handled 20～40min, cleans, extracts stand-by;
3) after the above-mentioned processing, put into giant knotweed rhizome natural dye again and dye, dyeing recipe is: dye strength be pollutant weight 0.1～10%, pH value 3～6, bath raio 1: 20～100,80～100 ℃ of temperature, time 30～90min; Dye complete, the washing, the oven dry.
2. to protein, Mierocrystalline cellulose, nylon fibre, it is as follows that yarn or fabric carry out the painted step of back matchmaker:
1) pollutant is immersed in the water, make it fully wetting, take out then and extract, stand-by;
2) after the above-mentioned processing, put into the giant knotweed dyestuff and dye, dyeing recipe is: dye strength be pollutant weight 0.1～10%, pH value 3～6, bath raio 1: 20～100,80～100 ℃ of temperature, time 30～90min; Dye completely, wash, extract;
3) with Fe
2+, Fe
3+, Al
3+, the salt of mishmetal or its two kinds of mixtures are as mordant, concentration is 0.1～10% of pollutant weight, pollutant is under 40～80 ℃ of temperature, bath raio 1: 20～50 is handled 20～40min, cleans oven dry.
The beneficial effect that the present invention has is:
1) the present invention's lixiviate giant knotweed rhizome natural dye in alkaline aqueous solution, mainly be to consider that the main component of giant knotweed is anthraquinone class, diphenylethylene, naphthoquinones class and flavonoid compound, their molecular structure contains the phenolic hydroxyl group of some amount, under alkaline condition, can impel its ionization, improve the solubleness in the water greatly.The present invention prepares giant knotweed rhizome natural dye according to this principle exactly.
2) extract yellow natural dyestuff from the natural phant giant knotweed, abundant raw material, preparation technology are simple, steady quality; Good, biodegradable with the ecotope consistency; Can not cause environmental pollution in the preparation process; The dyeing scope is wide, can dye to protein, Mierocrystalline cellulose, polyamide fabric, and dye uptake height, colour fastness are good; Dyeing back fabric is worn safety, does not have carcinogenic, teratogenesis or causes allergic reaction; Therefore, its market outlook are very wide.
