Abstract
The present invention relates to a dyeing method of cationic dyes for wool. A special dye accounting for 0.01 wt% to 3 wt% of an object to be dyed is adopted, water accounting for 30 to 100 times of the weight of the object to be dyed is added, acetic acid or alkali liquid are added to adjust the pH to be from 2 to 8, cleaned wool, silk fibers or fabrics are put in a dye vat after the special dye, the water and the acetic acid or the alkali liquid are uniformly stirred, dye liquid is circulated by a pump form 10 to 30 minutes, the temperature of the dye liquid is raised to 98 DEG C to 100 DEG C in the temperature raising speed of 1 to 2 DEG C/min, the heat insulation is kept for 30 to 60 min, the dye liquid is cooled to the normal temperature, residual liquid is put to a residual liquid storing container, a loose colour on the dyed object is washed off, and then the dyed object is dried and baked. In the present invention, the special dye and the acid and alkali for adjusting the pH are added, other assistants do not need to be additionally added, and therefore, the dyeing and finishing residual liquid can be preserved for use at next dyeing time. The present invention has the advantages of simple dyeing technology and improvement of environmental pollution, and can be used for dyeing wool and silk fabrics, wool-nitrile turbid textiles and fur.
Description
Technical field
The present invention relates to be used for the colouring method of the hair of hairs (wool, the rabbit hair), silk with cation dyes.
Background technology
At present, can pass through ACID DYES, weak acid dye, neutral dye, chrome dye, 1: 1 type premetallized dye, 1: 2 type premetallized dye, REACTIVE DYES, different auxiliary agents (as levelling agent, mordant, softener, diffusant, bleeding agent), dye under the condition of different acidity.In recent years also the someone proposes by different auxiliary agents, with cation dyes and DISPERSE DYES to hairs (wool, the rabbit hair), silk dyes, also existing with water on the dyeing is ambient condition and solvent dyeing technology that dyes under surfactant, blowing agent condition and foam dyeing technology, these colouring methods all exist various weakness and deficiency to some extent, poor as dyefastness, strong excessively acid dye bath causes damage to fiber; A lot of ACID DYES all belong to the forbidding dyestuff, not only will discharge a large amount of colorful wastewaters. but also also contain in the waste water and a large amount of environment is caused poisonous, detrimental substance.For the dyeing of multiple fiber mixed fabrics, it is more not enough that these methods and technology just seem, complexity, and difficulty.
These problems all influence the development of wool industry.Therefore development is fit to the dyeing new method of the dedicated dye of hairs, silk dyeing, seems important and urgent all the more.
Summary of the invention
For solving the existing problem of current different dyes coloured differently technology, the objective of the invention is to propose a kind of dyeing and finishing hairs, silk fiber textiles and hair nitrile blend fibre textiles of can be used for, also can be used for the method that the dyestuff of dyeing and finishing fur dyes, its colouring method technology is simple, easy to operate, dyeing and finishing quality is good, cost is low, the coloured sewage that is discharged reduces significantly, the current relatively similar dyeing of harmful substance in the sewage also has significantly and to descend, and significantly reduces dyeing to harm that environment caused.
Colouring method of the present invention adopts the hair cation dyes with following general structure:
Wherein,
R
1: be selected from a kind of element among F, the Cl;
R
2: be selected from naphthylamino, naphthoxy, phenylamino, phenoxy group and have amino or the compound of hydroxyl;
D
+: be selected from any one CATION in the cation dyes;
Dyeing according to the following steps: add entry in the dye vat, the water yield is to wait to dye 30～100 times of thing weight, the ON cycle pump stirs water in the cylinder, under greater than 10 ℃ normal temperature, amount with the 0.01-3% that waits to dye thing weight adds dedicated dye, add acetic acid or liquid caustic soda again, adjust PH at 2-8, after stirring evenly, will be through the hairs of cleaning, silk fiber or fabric are put into dye vat, continue to make the dye liquor circulation 10-30 minute with pump, make dye liquor temperature rise to 98-100 ℃ by 1-2 ℃/minute programming rate again, and be incubated 30-60 minute, and be cooled to normal temperature then, the dye vat raffinate is discarded to the raffinate storing containers, add the normal temperature clear water in the dye vat, washing dyeing and weaving thing 2-3 time is washed loose colour off, pollutant is dried again, oven dry, handle.
Better effects if when being 4-7 with PH in the said method.
When carrying out the next group hairs, when silk fiber or textile dyeing, the staining jar raffinate of last consignment of is put into dye vat, add water, with adjust the water yield in the cylinder be wait to dye thing 30-100 doubly, add dyestuff, to reach the dye level 0.01-3.00% of pollutant, add acetic acid or liquid caustic soda again, adjust pH between 2-8, add hairs to be dyed again, silk fiber or fabric continue to make the dye liquor circulation 10-30 minute with pump. heat up by 1-2 ℃/minute programming rate again, when temperature rises to 98-100 ℃, be incubated 30-60 minute, be cooled to normal temperature then, emit the dye vat raffinate, add the normal temperature clear water again and wash pollutant to the raffinate storing containers, through 2-3 time washing, loose colour is washed off. again pollutant is dried, oven dry is handled.
Colouring method of the present invention except that adding dedicated dye and adjusting the soda acid of PH, need not additionally to add other auxiliary agents in dyeing and finishing process, as levelling agent, diffusant, bleeding agent, can reduce the dyeing and finishing cost thus.It is one of main feature of this invention that the dyeing and finishing raffinate can be applied mechanically, and except that adding dedicated dye and adjusting the soda acid of pH, need not with adding other compounds in the dyeing course.Therefore, the dyeing and finishing raffinate can continue to utilize, and promptly raffinate is through adding an amount of dyestuff and water, adjust dye level, and control and promptly can apply mechanically after the soda acid amount reaches suitable pH value, this not only can reduce the dyeing and finishing cost greatly, can also reduce a large amount of discharge of wastewater. dwindle negative effect to environment.
The present invention is not only applicable to monochrome dyeing, and fine blending also can be adopted one-bath dyeing for hair, shortens technology widely and simplifies operation.
The specific embodiment
Embodiment 1:
Add 450g water in the dye vat of 500ml, add hair cation dyes 0.05g (blue look), adjusting pH is 5, stirs, add washed 5g wool cloth, close dye vat, start and stir, programming rate is 1 ℃/minute, rise to 98 degree after, insulation (98-100 degree) 60 minutes.Insulation finishes, and is cooled to normal temperature and opens dye vat and pour out raffinate and be used for applying mechanically next time.Dying good wool cloth, to be washed till wash water with clear water colourless, takes out wool cloth, through dry, oven dry promptly finishes dyeing.Dyeing quality index example is in table one
