Abstract
The present invention relates to a kind of chemical methodes for identifying silk fabrics vegetable colour, immerse in reagent of stripping after needing the dyeing silk fabrics identified wetting, if decoloration completely after immersion, illustrate that the dyestuff in the silk fabrics is vegetable colour；If silk fabrics no bleaching, take out and rewetted after cleaning, immersed in color changing reagent, such as the blackening of silk fabrics color after immersion, then shows that the dyestuff in the silk fabrics is vegetable colour.If not blackening, which is chemical synthetic dye dyed fabric.Reagent of wherein stripping uses the aqueous solution of citric acid and sodium acetate, color changing reagent uses the aqueous solution of iron ammonium sulfate and sodium chloride, the present invention generates different metachromatisms under the effect of identical chemical reagent from chemical dye using vegetable colour in silk fabrics, and whether the dyestuff effectively simply identified in dyeing silk fabrics is vegetable colour.
Description
Technical field
The present invention relates to a kind of methods of differential staining fabric vegetable colour, pass through more particularly to one kind simple
Chemical means carry out the method for differential staining silk fabrics vegetable colour.
Background technique
Since vegetable colour has good Environmental compatibility and medicinal health-care function, the exploitation of vegetable colour dyed textiles
Meet the development trend of current textile manufacturing.For a kind of textile of dyeing product, how to identify whether it is vegetable colour
The problem of dyeing, it has also become textile production and trading enterprise are in a bottle for expanding the business development of vegetable colour dyed textiles
Neck.It is that nothing can be carried out to the vegetable colour in ancient textiles by a kind of mini optical fibre spectral technique in archaeological research
Damage identifies, but equipment needed for identification is special, and analysis personnel need to have the spectral instrument operation and analysis ability of profession, China
Most of production trade type enterprises do not have these conditions.
Summary of the invention
A kind of dyeing easy to operate is provided the technical problem to be solved by the present invention is to the status for the prior art
The chemical discrimination method of silk fabrics is generated not under the effect of identical chemical reagent using vegetable colour in silk fabrics with chemical dye
Same metachromatism, whether the dyestuff effectively identified in dyeing silk fabrics is vegetable colour.
For the technical scheme of the invention to solve the technical problem is: the identification silk fabrics vegetable colour chemistry
Method, it is characterized in that the following steps are included:
1) the dyeing silk fabrics immersion after being soaked with clear water is stripped in reagent, if decoloration completely, illustrates after immersion
Dyestuff in the silk fabrics is vegetable colour；
Wherein, the aqueous solution that reagent is citric acid and sodium acetate of stripping, wherein the concentration of citric acid is 3%-
30%, the concentration of sodium acetate is 1%-2%；
If 2) silk fabrics no bleaching, taking-up rewets after being cleaned with clear water, immerses in color changing reagent, such as silk weaving after immersion
Damp blackening is looked for, then illustrates that the dyestuff in the silk fabrics is vegetable colour, if not blackening, which is chemical synthetic dye
Dyed fabric；
Wherein, color changing reagent is the aqueous solution of iron ammonium sulfate and sodium chloride, wherein the concentration 3%- of iron ammonium sulfate
15%, sodium chloride concentration 1%-2%.
The invention adopts the above technical scheme, which has the following advantages:
(1) vegetable colour in silk fabrics can effectively be identified by not needing special installation.
(2) easy to operate, it is not high to operating environment requirements.
(3) visual result, result can be clearly observed by being not required to analyze by data.
Detailed description of the invention
Fig. 1 is the process flow chart of the embodiment of the present invention.
Specific embodiment
Of the invention is described in detail with reference to the accompanying drawings and examples.
As shown in connection with fig. 1, the present invention is acted on chemical dye in identical chemical reagent using vegetable colour in silk fabrics
Lower to generate different metachromatisms, whether the dyestuff come in differential staining silk fabrics is vegetable colour.It mainly passes through following two
A step is realized:
1), first that citric acid and sodium acetate is soluble in water, it is configured to reagent of stripping, the dense of citric acid described in reagent of stripping
Degree is 3%-30%, and the concentration of the sodium acetate is 1%-2%；Then after the dyeing silk fabrics identified being needed to be soaked with clear water
It is immersed in the reagent of stripping, decolourizes, illustrate in the silk fabrics completely if dyeing silk fabrics in 24 hours after immersion
Dyestuff is vegetable colour；If taken out the silk fabrics without decolourizing completely, into next step.
2), first that iron ammonium sulfate, sodium chloride is soluble in water, it is configured to color changing reagent, sulfuric acid described in color changing reagent is sub-
The concentration of iron ammonium is 3%-15%, and the concentration of the sodium chloride is 1%-2%；Then it will not be taken off after aforementioned reagent of stripping impregnates
The dyeing silk fabrics of color rewets after being cleaned with clear water, is immersed in the color changing reagent, interior for 24 hours as silk fabrics color becomes after immersion
It is black, then show that the dyestuff in the silk fabrics is vegetable colour.If not blackening, which is that chemical synthetic dye dyeing is knitted
Object.
Above-mentioned citric acid, sodium acetate, iron ammonium sulfate, sodium chloride concentration be mass percentage concentration.
Operation of the present invention is simple and convenient, is not required to effectively identify the dyestuff of dyeing silk fabrics by special installation
It whether is vegetable colour.
Claims (1)
1. a kind of chemical method for identifying silk fabrics vegetable colour, it is characterised in that the following steps are included:
1) the dyeing silk fabrics immersion after being soaked with clear water is stripped in reagent, if decoloration completely in 24 hours after immersion,
Illustrate that the dyestuff in the silk fabrics is vegetable colour；
Wherein, the aqueous solution that reagent is citric acid and sodium acetate of stripping, wherein the concentration of citric acid is 3%-30%, vinegar
The concentration of sour sodium is 1%-2%；
If 2) silk fabrics no bleaching, taking-up rewets after being cleaned with clear water, immerses in color changing reagent, after immersion in 24 hours such as
Silk fabrics color blackening then illustrates that the dyestuff in the silk fabrics is vegetable colour, if not blackening, which is chemical synthesis
Dyeing fabric；
Wherein, color changing reagent is the aqueous solution of iron ammonium sulfate and sodium chloride, wherein the concentration 3%-15% of iron ammonium sulfate, chlorine
Change na concn 1%-2%；
The citric acid, sodium acetate, iron ammonium sulfate, sodium chloride concentration be mass percentage concentration.
