Abstract
The invention discloses a method for dying fabrics by the color combination of vegetable dyes, which belongs to the technical field of the fabrics. The method comprises the following steps that two and more than two extracted vegetable dyes are mixed in a certain proportion, and a reasonable dying process is formulated according to the dying properties of various vegetable dyes to dye different colors on the different fabrics. The method breaks through the defect of single color variety of the vegetable dyes, enriches the color variety of the vegetable dyes on the fabrics, enlarges the use range of the vegetable dyes, enables the fabrics to be bright in color, colorful in colors and elegant in hues, and lays the foundation for the wide application of the vegetable dyes on the fabrics.
Description
Technical field
The present invention relates to a kind of vegetable colour color matching method; Specifically with two kinds and abovely mix according to a certain percentage through the vegetable colour that extracts; Again according to the dyeability of various vegetable colours, formulate rational dyeing on different textiless, dye various colors.Belong to field of fabric producing technology.
Background technology
Some customs are used for the synthetic dyestuffs on the textiles, and are because of its serious environment pollution and harmful health, progressively disabled at present.Because the raw material of synthetic dyestuffs is mainly oil, in the long run, its resource is shortage day by day, do not meet the requirement of sustainable development, moreover " back to nature " has been the tendency of the day.Thus, caused the attention of people in recent years, because the existing long history of the application of natural plant fuel to traditional natural dye; Various plant fuels are applied in to be got over general especially on the textiles, vegetable colour not only has supplementary function to textile dyestuff, and main cause is that also it and ecological environment compatibility are good; Biodegradable; Environmentally safe, and nontoxic, and the vegetable colour that has is also with health role to human body.In addition, vegetable colour aboundresources, dyeing color and luster nature.
The textiles thing of vegetable colour dyeing also has unique medicinal health-care function except that dressing function, meet the modern to environmental protection and healthy pursuit.But vegetable colour dyed color kind is few, and common majority is blue, red and yellow kind; Purple, green and the black kind of having only only a few, and plant material is rare, and cost is high; Dyeability is undesirable, and this is the application of the vegetable colour of limit to a great extent.
Summary of the invention
The objective of the invention is to overcome existing staining technique weak point, a kind of color matching and colouring method of vegetable colour is provided, enriched the color category of vegetable colour dyeing, make textiles bright in colour, the color nature, tone elegance and good hand feeling are abundant.According to method provided by the present invention, vegetable colour can be allotted any needed color.
The technical scheme of prior art that the present invention solves is: a kind of method of vegetable colour dying fabrics by color combination, take following processing step:
A. the pre-treatment of textiles: with various grey fabrics carry out destarch, concise, come unstuck, above-mentioned one or more pre-treatments such as scouring of wool, carbonization and bleaching;
Textiles comprises one or more blending and woven that interweaves and the knitted fabric in cotton, fiber crops, viscose glue, silk, wool, terylene, the nylon.
B. the preparation of dye liquor:
Select suitable vegetable colour extraction scheme to carry out the extraction and the preparation of dyestuff according to different vegetable colour raw material properties; Be specially: at first with the vegetable colour raw material pulverizing, select any method in following two kinds of methods to obtain the vegetable colour dye liquor according to the character of vegetable colour then, comprising:
1. put into the comminuted plants raw material water or ethanol immersion, decoct, filter extraction then, obtain dye liquor;
2. add vegetable colour in the entry, and then add reductant and reduce in soda bath, make dye liquor.
In step b 1. in used concentration of alcohol be 0%-80%, extraction temperature is 30-90 ℃, the time is 10-60min.
In step b 2. in dye strength be 0.1-10g/L; The reductant that is added is one or more in sodium dithionate, thiourea dioxide, the thiocarbamide, and the concentration of said reductant is 1-15g/L, and caustic soda concentration is 0-10g/L; Reaction temperature is 10-90 ℃, and the reaction time is 5-30min.
In the plant material of step b in 1. is Yellow series vegetable colour and red series vegetable dyestuff; Described Yellow series vegetable colour comprises one or more combinations in rheum officinale, turmeric, the coptis, cape jasmine, the sophora flower, and described red series vegetable dyestuff comprises one or more combinations in madder, bush, the safflower; The vegetable colour of said step b in 2. is the blue series vegetable dyestuff through soaking fermentation; This vegetable colour comprises one or more combinations of indigo plant, woaded blue, acanthaceous indigo; Adding quick lime fully stirs deposition and makes vegetable colour, and this technology has been the routine techniques of knowing for people.
C. vegetable colour color matching and dyeing: at least two kind of plant dyestuff dye liquors that will obtain as stated above mix according to the ratio of appointment and obtain mixed liquor, join mixed liquor in the textiles, add reductant again.And add sodium chloride or sodium sulphate, and be that the pH value of 30-100 ℃ of inner control mixed liquor is 2-9 at dyeing temperature, dyeing time is 40min-90min; Soap at last, wash and dry, accomplish dyeing course.
The reductant that in step c, adds is one or more in sodium dithionate, thiourea dioxide, the thiocarbamide, and its concentration is greater than 0g/L, less than 5g/L; Sodium chloride or sodium sulfate concentration are greater than 0g/L, less than 100g/L.
The vegetable colour that arrives involved in the present invention belongs to different types.Some belongs to reducing dye, and some belongs to directly or ACID DYES.Dissimilar vegetable colours, dyeing is different.The disclosed dyeing of the present invention is taken into account the dyeability of all kinds of dyestuffs, make the dyestuff that is combined together can both be preferably on dyeing on textiles.Thereby remedied the deficiency of existing staining technique, enriched the color category of vegetable colour dyeing, enlarged the scope of application of vegetable colour.
