Abstract
The invention discloses a method for dyeing an acrylic fabric with bacterial dye prodigiosin. The method is characterized in that the amount of the dye used is 3 percent (o.w.f); the volume ratio of alcohol solvent to water is 1-2:2-3; the bath ratio is 1 to 40; the pH value is 4.0 to 6.0; the dyeing temperature is 90 to 95 DEG C; and the dyeing time is 50 minutes. The dyed acrylic fabric has high antibacterial property and a bacteriostasis rate of over 90 percent; and in addition, the dyed acrylic fabric has high washing fastness, high rubbing fastness, bright color and great application prospect.
Description
Technical field
The present invention relates to the colouring method field of bacterial dye prodigiosin, particularly a kind of bacterial dye prodigiosin is to the colouring method of acrylic fabric.
Background technology
In recent years, because the influence of environmental problem and energy problem, people are tending towards pursuing continuable, and are eco-friendly and the human health advantageous method produced dyestuff.The exploitation natural dye is the general trend that the world uses the dyestuff development, natural dye be meant from plant, animal or mineral resources, obtain, seldom or not pass through the dyestuff of chemical process, a lot of natural dyes have safe and reliable, the tone nature, near advantages such as natural materials, natural, multi-functional is the trend of dyestuff development.Therefore from natural resources, filter out the microorganism that can produce natural dye, so the natural dye of developing new product variety, especially have functional natural dye, have broad prospects.Along with development of biology, utilize biotechnology to produce natural dye and opened up wide field for people.Biofermentation product stability height, selectivity is strong, and is pollution-free, and production process does not have injury to the people, and therefore, biological fermentation process is a kind of method of good synthetic dyestuffs.
The natural colouring matter of the methoxyl group pyrrole skeleton structure that the bacterial dye prodigiosin is made up of three pyrrole rings, be the secondary metabolite of some actinomyces, Serratieae and other bacteriums, have multiple biologically actives such as immunosupress, antibacterium, antimycotic and anti-malarial.Therefore, the bacterial dye prodigiosin as dyeing after its DYED FABRICS just have antibiotic function, and have anticancer effect.
This bacterial dye is a kind of bolarious pigment that is, and it is reflective to have green, fusing point 151-152 ℃, and water-soluble hardly, be soluble in ethanol, chloroform and benzene, structure is as follows:
This dyestuff is orange-yellow in alkalescence or neutral solution, take on a red color in the acid solution.With ethanol is solvent, and prodigiosin has characteristic absorption at the 537nm place under the acid condition, at the 466nm place characteristic absorption is arranged under the alkali condition.But up to the present, the bibliographical information of researching and developing and studying about this dyestuff also seldom.
Summary of the invention
Technical problem to be solved by this invention provides the colouring method of a kind of bacterial dye prodigiosin to acrylic fabric, acrylic fabric after the dyeing has good antibacterial property, bacteriostasis rate is more than 90%, have good washing fastness and fastness to rubbing in addition, dyeing back fabric color is bright-coloured, has a good application prospect.
A kind of bacterial dye prodigiosin is characterized in that the colouring method of acrylic fabric: dye dosage is 3% (o.w.f), and the volume ratio of alcohols solvent and water is 1～2: 2～3; bath raio is 1: 40; the pH value is 4.0～6.0, and dyeing temperature is 90 ℃～95 ℃, and dyeing time is 50min.
Dye dosage is 3% (o.w.f), and the volume ratio of ethanol and water is 1: 2, and bath raio is 1: 40, and the pH value is 6.0, and dyeing temperature is 95 ℃, and dyeing time is 50min.
Dye dosage is 3% (o.w.f), and the volume ratio of methyl alcohol and water is 2: 3, and bath raio is 1: 40, and the pH value is 4.0, and dyeing temperature is 90 ℃, and dyeing time is 50min.
Bacterial dye colouring method of the present invention definite as follows draws the dyeing condition that dyes acrylic fabric the best:
A. choosing ethanol and water or methyl alcohol and water dyes to acrylic fabric as the solvent of dyestuff, the maximum absorption wavelength of doing bacterial dye under the condition of solvent at ethanol and water appears at the 538nm place, dyeing back fabric is bright-coloured redness, so bacterial dye has the condition as dyestuff;
B. at first to determine the best ethanol and the ratio of water dyestuff can be dissolved fully, and be easy to dyeing;
C. back in pH value to dyeing, bath raio, dyeing conditions such as dyeing temperature and time have been done further research to the influence of Color, determine best dyeing condition at last;
When d. methyl alcohol and water are as the solvent of dyestuff, optimum dyeing condition definite the same.
Beneficial effect
Acrylic fabric after dyeing dyeing of the present invention has good antibacterial property, and bacteriostasis rate has good washing fastness and fastness to rubbing in addition more than 90%, and dyeing back fabric color is bright-coloured, has a good application prospect; And this colouring method can apply to some water insoluble and improper dyeings as DISPERSE DYES.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
The preparation of prodigiosin dyestuff
At first, with bacterial classification (the clayey Serratieae of buying, available from Chinese medicine bacterium preservation administrative center) dilute, after bacterium after will diluting coat plating medium (dusty yeast 5g/L, peptone 10g/L, glucose 10g/L, agar powder 20g/L) on put into constant incubator and cultivate, the darker bacterial strain of picking haematochrome and color is coated on the plating medium, and this bacterial strain is preserved under 4 ℃ condition.The bacterial strain that screens is cultivated 15h in seed culture medium (dusty yeast 4.5g/L, peptone 12g/L, NaCl 2.5g/L, KCl 3g/L, glucose 2g/L), the back is inserted fermentation medium and is cultivated 30h.
Respectively supernatant is separated with thalline.Supernatant directly extracts prodigiosin with ethyl acetate from the aqueous solution, the earlier centrifugal back of flocculate concentrates the back with rotary evaporator and extracts in acidic methanol, methanol extraction prodigiosin method: will precipitate back adding 500mL methyl alcohol in the triangular flask that partly joins 1000mL, transferring pH with HCl is 4-5, seals film and seals; At rotating speed is to stir 12h on the 200rpm magnetic stirring apparatus, leave standstill 3h supernatant methyl alcohol separated with the bottom sediment, after add 300mL methyl alcohol the more residual prodigiosin in the sediment extracted once again, the back concentrates uses ethyl acetate extraction again; The ethyl acetate that is dissolved with prodigiosin is concentrated, further use chloroform and water abstraction purification, the back obtains product with silica gel column chromatography.
Embodiment 2
To dye the acrylic fibers cloth specimen by following technology respectively tests:
Technology 1: dye dosage 3% (o.w.f), ethanol: water is 1: 2, bath raio 1: 40, pH is the 50min that dyes under 6.0,95 ℃ of conditions.
Technology 2: dye dosage 3% (o.w.f), methyl alcohol: water is 2: 3, bath raio 1: 40, pH is the 50min that dyes under 4.0,90 ℃ of conditions.
Measure its fastness to rubbing basis according to GB/T 3920-1997 " textile color stability test colour fastness to rubbing ", the AATCC standard is carried out the wash resistant test.
The dry fastness that finally draws by technology 1 dyeing back acrylic fabric is 4 grades, and fastness to wet rubbing is 4-5; The dry fastness of technology 2 dyeing back fabrics is the 3-4 level, and fastness to wet rubbing is 4-5; The soaping fastness of dyeing back fabric is the 4-5 level.
Carry out antibacterial fabric is tested according to AATCC standard 100 according to above technology dyeing back fabric.The result shows that the bacteriostasis rate of technology 1,2 dyeing back acrylic fabrics is respectively 98.5%, 98%.
