Abstract
The invention discloses the colouring method of a kind of indigo pigment dyeing silk fabric, this comprises the following steps: indigo pigment is dissolved in acid solution by (1), regulate pH value and temperature, add ultraviolet absorber and antioxidant, add earth solution, stir to mix homogeneously, form dye liquor; (2) silk fabric be impregnated in dye liquor with bath raio for 1:50, ultrasonic, regulate dye liquor temperature and ultrasonic dyeing time, take out silk fabric and carry out washing and drying, obtain the silk fabric contaminated. The present invention utilizes Food Indigo pigment that silk fabric is dyeed, utilize rare earth shorten dyeing time and reduce dyeing temperature, improve the Color of silk fabric, dye under Ultrasonic Conditions, not only reduce thermal energy consumption, and improve dye-uptake and the color fastness of fabric. The dye-uptake of silk fabric prepared by this method and color fastness are all significantly high, all reach processing and take requirement.
Description
Technical field:
The invention belongs to textile material technical field, particularly to the colouring method of a kind of indigo pigment dyeing silk fabric.
Background technology:
Before synthetic dyestuffs come out, all colors are all from nature, and synthetic dyestuffs instead of natural dye application in textile dyeing gradually with its abundant color and luster and excellent dyefastness. And the problem of the production of synthetic dyestuffs and environment, natural dye is good because of its being compatible with the environment property, biodegradable, and raw material is renewable, to the skin premium properties without anaphylaxis and carcinogenecity, attracts attention again.
Natural dye derives from animal, plant, mineral and microorganism, wherein based on vegetable colour, is broadly divided into indigoid, Anthraquinones, flavonoid, alkaloids .alpha.-5:6-benzopyran, Polyphenols, diones and carotenoids. There is many problems in natural dye, as being difficult to standardized production, the affinity of textile fabric is low in the application, washable poor with color fastness to light, and chromatograph is complete, and required dyeing time is long. Some natural dye is to add mordant in dyeing, because mordant is many containing heavy metal ion, disagrees with the original intention of natural dye environmental protection.
Silkworm silk belongs to protein fibre, had both contained acidic-group carboxyl, and had again basic group amino, in amphotericity in molecular structure. The dyestuff of current silk fiber mostly is acid stain and reactive dye.
Summary of the invention:
It is an object of the invention to provide the colouring method of a kind of indigo pigment dyeing silk fabric, the inventive method environmental protection, utilize rare earth to improve dye-uptake and the color fastness of silk fabric in conjunction with ultrasonic means.
The purpose of the present invention is achieved through the following technical solutions:
The colouring method of a kind of indigo pigment dyeing silk fabric, comprises the following steps:
(1) indigo pigment is dissolved in acid solution, regulates pH value and temperature, add ultraviolet absorber and antioxidant, add earth solution, stir to mix homogeneously, form dye liquor;
(2) silk fabric be impregnated in dye liquor with bath raio for 1:50, ultrasonic, regulate dye liquor temperature and ultrasonic dyeing time, take out silk fabric and carry out washing and drying, obtain the silk fabric contaminated.
Preferred as technique scheme, the indigo pigment described in step (1) is Food Indigo pigment.
Preferred as technique scheme, the acid solution described in step (1) is at least one in acetic acid, citric acid, maleic anhydride, ortho phosphorous acid.
Preferred as technique scheme, the pH value described in step (1) is 2-6, and temperature is 40-50 DEG C.
Preferred as technique scheme, ultraviolet absorber and antioxidant described in step (1) are vitamin C and vitamin E.
Preferred as technique scheme, the acid solution that earth solution is rare earth chloride described in step (1).
Preferred as technique scheme, the earth solution concentration described in step (1) is 0.1%-0.3%.
Preferred as technique scheme, the ultrasonic time described in step (2) is 0.5-1h.
Preferred as technique scheme, the dye liquor temperature described in step (2) is 80-95 DEG C.
The beneficial effects of the present invention is: dye when Ultrasonic Dyeing, can make dyeing uniform in effect, give the good dye-uptake of fabric, light fastness and washing fastness, the method thermal energy consumption is few. Dye liquor increases the UV absorbent such as vitamin C, vitamin E and antioxidant, the sunlight fastness of dyed fabric can be improved. Utilize rare earth as mordant, environment and pollution problem can be avoided while improving natural dye dying fastness. With the high-grade silk fabric of natural plant dye dyeing, can the good characteristics of natural plant dye and silkworm silk being combined, obtained silk fabric not only outward appearance is magnificent, graceful noble, and comfort and health, environmental protection.
