Description
Technical Field
The invention belongs to the field of disperse dyes, and particularly relates to a disperse purplish red dye mixture with high color fixing rate and high washing fastness.

Detailed Description
Example 1
Weighing 17.5g of disperse red, 22.5 g of disperse violet and an auxiliary agent (MF30g, 30g of sodium lignosulfonate) according to the weight ratio, sanding the materials together with water, and spraying to prepare the disperse purplish red dye mixture.
Wherein R in formula (I)1＝CH2COOC2H5,R2＝CH2COOC2H5、
In the formula (II) R3＝OCH3R4＝CH2COOC2H5,R5＝CH2COOC2H5。
Examples 2 to 8
Examples 2 to 8 were prepared separately in the same manner as in example 1 except for the compounding ratio, and R in the formula (I)1And R2And R in the formula (II)3、R4And R5Changes were made and it is further noted that R is not listed in the table3Then R is3Specifically, as shown in table 1:
TABLE 1 Structure and specific compounding ratio of examples 2-8
According to the prior patent, a disperse red date dye composition (publication No. CN102277012A) is prepared by a method disclosed in the prior art to be used as a control group test, 1g of the disperse red date dye mixture obtained in the example 1-8 is respectively taken and dispersed in 500ml of water, 20ml of dispersion liquid and 80ml of water are respectively taken after being uniformly mixed, the PH value is adjusted to be 4-5 by acetic acid, 2g of terylene superfine fiber is added, the dyeing treatment is carried out according to the national standard GB/T2394-2006 method, the washing fastness is tested according to GB/T3921-2008, and the dyeing rate is carried out according to GB/T9337-2001.
Table 2 shows the results of the test of the fastness to washing (unit: grade) of examples 1 to 8 and the control group
| Examples | Washing fastness is 60 DEG C | Dye uptake |
| 1 | 5 | 94.5％ |
| 2 | 5 | 94.5％ |
| 3 | 5 | 95％ |
| 4 | 5 | 95.5％ |
| 5 | 5 | 92.5％ |
| 6 | 5 | 94.5％ |
| 7 | 5 | 93.4％ |
| 8 | 5 | 93.3％ |
| Control group | 5 | 86.5％ |
From the above table, it can be seen that the disperse date red of the present invention has excellent washing fastness when used for dyeing polyester superfine fiber, and the dyeing rate is greatly improved, which is much higher than that of the comparative example.
The principle is as follows: 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 a solubility parameter, generally, the closer the solubility parameter of the dye is to the solubility parameter of the terylene (sigma is 10.8, and the better fastness is shown in the research that sigma is 10.8 +/-0.5), the better the dye uptake is, and the better the dye is fixed on the fabric, which can be understood from similar compatibility. Meanwhile, dyes entering the interior are resolved under the action of a dispersant, so that the dyes are dissociated out of the interior of the fabric, the difference between the fixing and resolving capacities determines the degree of dyeing of the dyes, in the disperse red (I) and disperse violet (II) structures, the solubility parameters of the dyes are between 10.3 and 11.25 and are closer to the solubility parameters of terylene than those of Ciba company and patents, particularly the solubility parameters of the selected dyes (see Table 1) are quite close to the solubility parameters of terylene, the solubility parameters of three components in a comparative example (red 356 sigma-9.29 red 376 sigma-11.73 and violet sigma-11.77) are far away, so that the selected compounds of the patent have better dyeing rate, meanwhile, the dyes of the formula (I) and the formula (II) have ester groups in the structures, and the-CH is easily formed in the alkali washing process after dyeing2COO or-CH (CH)3) COO negative ions and azo-group meta-position chlorine have two electron-withdrawing nitro groups, so that sodium phenolate is easily formed under alkaline conditions, the surface of the fabric is floated to form water-soluble dye, the water-soluble dye is easy to wash away, and better washing fastness can be obtained.
Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the invention as defined by the appended claims. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
