Abstract
The present invention belongs to an acid mordant dye dyeing method for wool and the fabrics of wool, which aims to reduce the consumption of red vitriol in mordant dyeing treatment. In the present invention, chitosan acetate is used for replacing partial red vitriol in mordant dyeing treatment, and other process conditions in the prior art are not changed. The largest replacement quantity of the chitosan acetate to the red vitriol is 70%, and the replacement ratio is 1:1 (weight). The present invention not only reduces the consumption of the poisonous red vitriol, but also obviously reduces the content of chromium ions in dyeing wastewater.
Description
The invention belongs to wool and coloration of textile materials method thereof, particularly with acid mordant dye to wool and coloration of textile materials method thereof.
Acid mordant dye is widely used in wool and coloration of textile materials thereof.Its colouring method comprises with acid mordant dye dying thing and paint and using arsenic (potassium bichromate or sodium dichromate) mordant to carry out mordant dyeing and handle two parts.But this decoration method needs to use a large amount of great toxicity arsenic in mordant dyeing is handled, and make and contain a large amount of chromium ions in its dyeing waste-water, particularly the content of hexavalent chromium is very high, has substantially exceeded the discharge standard that is allowed, and all brings adverse effect for environment and health.Therefore, the arsenic consumption of managing to reduce in the above-mentioned decoration method is the current problem that needs solution.
The object of the present invention is to provide a kind of arsenic consumption that reduces also can reduce the acid mordant dye dyeing wool of content of chromium ion in the dyeing waste-water and the method for fabric thereof.
The solution that realizes the object of the invention is: replace the part arsenic with shitosan acetate in mordant dyeing is handled.Replace than being 1: 1(weight), promptly the addition of shitosan acetate equals the reduction of arsenic.Shitosan acetate is 70% to the maximum replacement amount of arsenic, and promptly Zui Da replacement weight range is greater than zero, is less than or equal to 70 percent.With the exception of this, dyeing of the present invention is identical with existing dyeing.
Consider from the angle of economy because the price of shitosan acetate is lower, so shitosan acetate to the replacement amount of arsenic with more than 30% for well, promptly replacing weight range is 30～70%.And best replacement weight range is 40～60%.
Shitosan (formal name used at school is (1 → 4)-2-amino-2-deoxidation-callose) is nontoxic, water insoluble, and its acetate water soluble, its molecular structural formula is:
Shitosan is a cationic nitrogenous type high polymer, good with protein fibre compatibilities such as wools, and form lake with anionic dyestuff in the chrome dye, sealed the hydrophilic radical of dyestuff so on the one hand, increased the molecule of dyestuff on the other hand, reduced water-soluble, thereby improved the washing fastness of dyestuff.In addition, contain amino and hydroxyl in the molecule of shitosan, so have the ability with multiple metal ion-chelant.Therefore, replacing the part arsenic with shitosan acetate does not only influence wool and coloration of textile materials fastness and physical property, and can reduce the content of chromium ion in the dyeing waste-water.
Embodiment 1: the wool fabric yellow colouration.
Existing technology:
(1) colouring: earlier with glauber salt 5%(0.Wf), glacial acetic acid 2%(0.Wf) be added in the dye bath, then add the yellow GG dyestuff of the good media of dissolving 1%(0.Wf), will dye thing then and put into dye bath and slowly heat up and boiled 50 minutes, reach the tone of being hoped;
(2) bleed off part dye bath liquid (being approximately 1/4), add water again till former dye bath ratio, and the dye bath temperature is dropped to below 75 ℃, so that carry out the transition to the mordant dyeing operation;
(3) mordant dyeing is handled: add sulfuric acid 1%(0.Wf) and the good arsenic 0.5%(0.Wf of dissolving) (0.Wf), slowly heat up again and boiled 40 minutes, reach complete film color;
(4) dye thing and wash out machine.
More than the percentage of each admixture be to account for the percentage by weight that dyes thing, be designated as 0.Wf.
The present invention:
(1), (2) are identical with (1), (2) of above-mentioned prior art;
(3) mordant dyeing is handled: add sulfuric acid 1%(0.Wf) and the good arsenic 0.3%(0.Wf of dissolving) and shitosan acetate 0.2%(0.Wf), slowly heat up again and boiled 40 minutes, reach complete film color;
(4) dye thing and wash out machine.
The dyefastness contrast test of above-mentioned two kinds of methods is as shown in table 1.
Can find out that from table 1 the present invention is identical with the dyefastness of prior art.
Embodiment 2, and B dyes pure wool thread with medium red
Condition: other 85/1, gross weight 4 grams, bath raio 1: 50
No. 1 sample: adopt existing dyeing (mordant dyeing does not add shitosan acetate in handling).
No. 2 samples: shitosan acetate consumption is 1/2 of No. 1 a sample arsenic consumption in mordant dyeing is handled, and the arsenic consumption is 1/2 of No. 1 sample, and all the other prescriptions and process conditions are all identical with No. 1 sample.
No. 3 samples: shitosan acetate consumption is 2/3 of No. 1 a sample arsenic consumption in mordant dyeing is handled, and the arsenic consumption is 1/3 of No. 1 sample, and all the other process conditions and prescription are all identical with No. 1 sample.
Result of the test shows: No. 2 the sample Dry Sack is dark than No. 1 sample, and No. 3 the sample Dry Sack is dark than No. 2 samples.Illustrate that replacing the part arsenic with shitosan acetate can save dyestuff.
Embodiment 3: the flat greatcoat of all woolen dyes Da Lan.
Prior art: the arsenic consumption is 2.3%(0.Wf)
The present invention: the arsenic consumption was 1.3%(0.Wf during mordant dyeing was handled), shitosan acetate consumption is 1%(0.Wf), all the other prescriptions and process conditions are same as the prior art.
The physical property of above-mentioned two kinds of method institute dyeing and weaving things is as shown in table 2.
Can find out that from table 2 the present invention does not influence the physical property of DYED FABRICS.
Embodiment 4: all-wool gabardine is caught cyan.
Prior art: the arsenic consumption is 0.8%(0.Wf).
The present invention: the arsenic consumption was 0.48%(0.Wf during mordant dyeing was handled, and shitosan acetate consumption is 0.32%(0.Wf), all the other prescriptions and process conditions are same as the prior art.
The content of chromium ion is as shown in table 3 in the dyeing mother liquor that is untreated of above-mentioned two kinds of methods.
Can find out from table 3: the content of chromium ion has obvious minimizing the dyeing mother liquor of the present invention, and especially the content of hexavalent chromium compared with prior art reduces 92%.
From above contrast test as can be seen: the present invention greatly reduces poisonous arsenic consumption, and content of chromium ion has minimizing significantly in its dyeing mother liquor.Content of chromium ion will be lower than discharge standard in the waste water that is discharged after dying the thing washing.Another advantage of the present invention is to save dyestuff.Because the price of shitosan acetate is low than arsenic.So the dyeing cost also will reduce.In addition, because the present invention does not change other process conditions of prior art, therefore be beneficial to and apply.
