Background
With the development of polyester fiber, superfine fiber appears, which has the characteristics of soft hand feeling, comfortable wearing and the like, and has become a textile raw material for textile enterprises at home and abroad, but because of the superfine diameter and the large surface area, the washing fastness and the dye uptake of common disperse dye are poor;
wherein, the dye uptake of the automobile bus disperse black WW-KS and the disperse dark blue W-RS is only about 80%, the dye uptake is improved by the patents with domestic publication numbers of CN103421347A and CN102352125A, but the dye uptake is only about 85%, and the low dye uptake means that more dyes enter sewage, thereby increasing much burden for the treatment of three wastes.

the invention has the beneficial effects that:
(1) in the structures of the disperse blue (I), the disperse violet (II) and the disperse orange (III), the solubility parameter of the dye is between 10.4 and 11.2, and particularly the selected dye; the solubility parameter is quite close to that of terylene, so the selected compounds of the invention have better coloring rate;
(2) the dyes of formula (I), formula (II) and formula (III) all have ester groups in the structure, and easily form-CH in the alkali washing process of dyeing post-treatment2COO negative ions and meta chlorine of azo groups are replaced by hydroxyl to form sodium phenolate under alkaline, so that loose colors on the surface of the fabric are easy to wash away, and better washing fastness can be obtained, therefore, the disperse black dye mixture has high dyeing rate and high washing fastness.
Detailed Description
The manufacturing method of the invention is as follows:
the raw materials are mixed uniformly according to the proportion, and are sanded and sprayed to obtain the disperse blue-black dye mixture.
The implementation of the preparation method 1:
12g of disperse blue (I-1), 10g of disperse violet (II 1), 17g of disperse orange (III-1), an auxiliary agent MF20g, 85A41g lignin and 200g of water are put together, sand milled and spray dried to obtain the disperse black dye mixture;
the preparation method 2 to 18 is implemented to prepare the following components in proportion:
Figure BDA0001757268300000061
Figure BDA0001757268300000071
the experimental demonstration is as follows:
respectively taking 1g of products obtained by implementing the manufacturing methods 1-18 and 1g of samples of patents CN103421347A and CN102352125A, respectively numbering the samples as a comparison sample 1 and a comparison sample 2, dispersing the comparison samples in 500ml of water, uniformly mixing, respectively taking 20ml of dispersion liquid and 80ml of water, adjusting pH to 4-5 by using acetic acid, adding 2g of polyester fabric for dyeing, carrying out dyeing treatment according to a national standard GB/T2394-2006 method, testing the washing fastness according to GB/T3921-2008, and carrying out the dyeing rate according to GB/T9337-2001; the test results of the dye uptake of the washing fastness are shown in the following table:
examples Washing fastness is 60 DEG C Dye uptake
1 5 92.5％
2 5 93％
3 5 93.6％
4 5 91.7％
5 5 94％
6 5 93.3％

16 5 93.5％
17 5 93％
18 5 92.8％
Comparative sample 1 5 83.5％
Comparative sample 2 5 82.5％
The dyeing process of the dye can be regarded as a process of dissolving the dye on chemical fibers, the dye uptake can be judged by solubility parameters, generally, the closer the solubility parameter of the dye is to the solubility parameter of the terylene (sigma is 10.8, the better the dye uptake and fastness within 10.8 +/-0.5 is shown by research), the better the dye uptake is, the better the dye is fixed on the fabric, and the same can be understood from similar compatibility. Meanwhile, the dye entering the inside can be analyzed under the action of the dispersing agent, so that the dye is dissociated out of the inside of the fabric, and the difference between the fixing and analyzing capabilities determines the dyeing rate of the dye.
From the above table, it can be seen that the disperse blue-black of the invention is used for dyeing terylene and blended fabrics thereof, and has excellent washing fastness, and the dyeing rate is greatly improved and is greatly higher than that of a contrast group.
