Abstract
The invention discloses a dyeing process of natural organic dye extracted from safflower, which comprises the following steps: preparing natural organic dye into solution, regulating acidity to prepare dye liquor, immersing the fabric to be dyed into the dye liquor, preserving heat for a period of time, taking out the fabric, squeezing and drying, immersing the fabric into the dye liquor for a period of time, taking out the fabric, and finally, carrying out squeezing, drying, rinsing and drying to finish the coloring. The invention has simple process and low production cost, reduces the pollution to the environment, and has the health-care functions of preventing ultraviolet radiation and promoting the microcirculation of human tissues when the underwear is made of the dyed fabric.
Description
Technical field
The present invention relates to a kind of dyeing of natural dye, relate in particular to a kind of dyeing of the natural organic dyestuff that from safflower, extracts.
Background technology
In science and technology underdeveloped period still, people use the archetype natural dye painted.Synthetic dyestuffs occur subsequently, since bright in colour, stable in properties, with low cost, within a very long time, almost replaced natural dye.Yet the synthetic dyestuffs DYED FABRICS has excitant to skin on the one hand, easily causes cutaneous lesions; In production and use procedure, also environment is produced on the other hand and pollute.Along with the enhancing of people's environmental consciousness and self health care consciousness, natural dye with its uniqueness nontoxic, harmless, to skin without anaphylaxis and carcinogenic, and preferably biological degradability and Environmental compatibility arranged and be subject to more and more people's favor.
That natural dye refers to obtain from the natural materials such as plant, animal, seldom pass through the dyestuff of chemical process, can be divided into vegetable colour, animal dye and mineral matter dyestuff according to the source.Vegetable colour is topmost natural dye, and it is to extract the dyestuff that obtains root, stem, leaf or the fruit from plant, grips son, tea etc. such as madder, Asian puccoon, bush, indigo, safflower, pomegranate, Winter-Spring, red bayberry, Huang.Wherein, safflower is the composite family annual herb plant of Dicotyledoneae, in 25 provinces and cities of China distribution is arranged all, and Xinjiang, Henan, Sichuan and zhejiang and other places are the major production areas.Contain carthamin yellow and carthamic acid in the safflower, carthamic acid solves glucose and safflower red pigment through hydrochloric acid water.Carthamin yellow is flavone compound in the safflower, accounts for 20%～25%, and haematochrome is to be used for the dyestuff of red colouration ancient times, account for spend heavy by 0.5%～1.4%.Modern medicine also find carthamin yellow have hypotensive, expand blood vessel, improve the organ blood supply, the formation of anticoagulation, inhibition thrombus, coronary artery dilator, improve the effects such as myocardial blood supply.In addition, carthamin yellow also has more widely as food coloring or food additives to be used, but it is more rare to be applied to the report of textile printing and dyeing for carthamin yellow and haematochrome, and relevant dyeing is also immature.
Research finds, the surface diffusion into the surface of these two kinds of polyhydroxy organic nano compounds of carthamin yellow and haematochrome is extremely strong, and reaction speed is fast, in the situation that 60～90 ℃ of low temperature, low concentration just can be painted to silk fabric in 15 minutes.Research also shows, the silk fabric that dyes with carthamin yellow organic nano dyestuff has the absworption peak appearance at the 257nm wavelength, illustrates that it has the ultraviolet radiation preventing performance.Owing to when safflower is made Chinese herbal medicine, can improve the microcirculation of tissue, it is with health role that the fabric of therefore dying with this dyestuff is made underwear.This shows, the dyeing of exploitation carthamin yellow and haematochrome not only has wide market prospects, and has very high social benefit and economic worth.
Summary of the invention
The object of the present invention is to provide that a kind of technique is simple, the dyeing of the natural organic dyestuff that extracts of environmental protection from safflower.
The inventor constantly attempts by a large amount of experiments, has obtained technical scheme of the present invention: a kind of dyeing of the natural organic dyestuff that from safflower, extracts, and concrete steps are as follows:
A. with the carthamin yellow water wiring solution-forming that extracts in the safflower, and regulate acidity and make stable yellow dye liquor;
B. then yellow dye liquor is incubated in 40～60 ℃, the fabric of wish dyeing is immersed in the dye liquor, make it homogeneous immersion 10～30min after, take out fabric and extract; Dry fabric is immersed 40～60 ℃ decide in the dye liquor behind 15～35min again, take out that fabric is extracted, rinsing, drying, painted operation is finished;
Or:
A1. the safflower red pigment that extracts in the safflower is made into orcein dye with the alkaline buffer solution of pH=8～12, and is incubated in 80～95 ℃, put into and want the dyeing and weaving thing and infiltrate to take out behind 10～30min and extract;
That B1. then the gained dry fabric is inserted different acidity decides 40～60 ℃ of dye liquor insulations, 15～20min DYED FABRICS red coloration, take out at last fabric through extract, rinsing, drying, namely the painted operation of haematochrome is finished.
The acidity of regulating dye liquor described in the preferred steps A is pH=2～5, and the mass concentration of the yellow dye liquor of preparing is 15%～24%.
The dye liquor of deciding described in the preferred steps B is that mass concentration is 2%～5% colloid sodium chloride solution.
Alkaline buffer solution among the preferred steps A1 is a kind of in borax-calcium chloride, borax-sodium carbonate, amion acetic acid-potassium chloride-NaOH or the sodium dihydrogen phosphate-sodium hydroxide buffer solution.The mass concentration of the orcein dye of preparing among the preferred steps A1 is 0.4%～1.2%.
Deciding dye liquor among the preferred steps B1 is that mass concentration is 2%～5% sodium chloride solution; The acidity of deciding dye liquor among the step B1 is pH=1～7.Along with the difference of deciding dye liquor acidity, among the step B1 redness be aubergine, blood red or orange red.
Baking temperature among preferred steps B and the B1 is 60-90 ℃.
Beneficial effect:
(1) the present invention has developed carthamin yellow and the application of haematochrome on fabric printing in the safflower, has reduced dyestuff to harm, but also has had health care, has greatly improved the value of safflower;
(2) dyeing environmental protection of the present invention has reduced the toxicity of dyeing waste-water, has alleviated the sewage disposal burden, is conducive to environmental protection;
(3) dyeing of the present invention is simple, and is with low cost, is convenient to suitability for industrialized production.
