Description
Technical Field
The invention belongs to the field of disperse dyes and preparation and application thereof, and particularly relates to a liquid disperse dye and a preparation method and application thereof.
Background
The disperse dye is the main colorant for dyeing and printing the polyester fabric. Because the disperse dye is insoluble in water, a uniform dispersion can be formed in water by the action of a dispersant. The water solubility of the disperse dye is very low, and the disperse dye is mainly in a micro particle dispersion state during dyeing. The dyeing mechanism of the dye is completely different from that of a water-soluble dye, no chemical bond reaction exists between the dye and the fiber, the fiber expands under the high-temperature condition and enters the fiber in a pore channel deposition mode, and the attraction and hydrogen bond fixation generated between molecules are utilized to finish the dyeing process. The dyeing methods adopted at present mainly comprise a carrier method, a high-temperature high-pressure method and a hot melting method. After the traditional disperse dye is used for dyeing, dyeing residual liquid contains a small amount of undyed dye, the undyed dye is easily adsorbed on the surface of polyester fiber to form loose color, the loose color cannot be removed by simple washing, and liquid alkali, sodium hydrosulfite, an acid reduction cleaning agent and the like are added to achieve the purpose of improving the color fastness.
Compared with powdery disperse dyes, the liquid disperse dyes have many incomparable advantages that ① liquid disperse dyes can achieve good dispersion effect by using less dispersant, the cost is saved, the dye utilization rate is improved, ② omits a spray drying process, simplifies a process, saves energy, ③ facilitates automatic material taking, accords with the automatic development trend of the printing and dyeing industry, ④ eliminates dust pollution and the like from the source, which leads the liquid disperse dyes to be gradually valued in recent years as a commercial preparation of the disperse dyes.
There are many methods for producing an ultra-fine liquid disperse dye, and the method can be roughly classified into a chemical processing method and a physical processing method. Wherein the chemical processing method comprises emulsion polymerization, solvent method, etc.; the physical processing method comprises high-pressure homogenization, ultrasonic preparation, and mechanical grinding. Different from a chemical processing method which needs to use a large amount of organic solvent, the physical processing method takes water as a medium, the process operation is simple and efficient, the technology is more mature, and the method is a processing mode which is widely used at present. Although the chemical method for preparing nano-powder has been studied in great numbers, the production cost is relatively high and the particle size distribution is wide. So, the industry is mainly using the physical mechanical grinding method to prepare the nanometer powder. The physical mechanical method is easy to prepare the nano powder with narrower particle size distribution, and meanwhile, the production cost is relatively low, the parameters are easy to control, and the batch production can be realized. Chinese patent CN110330810A prepares a superfine nano liquid dispersion color paste by a grinding method, wherein, a disperse dye is firstly dissolved by an organic solvent, then is added into a grinding system containing a hyper-dispersant, a wetting agent and water, the organic solvent is recovered, and then a stabilizer, a solvent and a bactericide are added for continuous grinding.

The dispersion and stability results of the liquid disperse dyes in examples 1 to 7 and comparative example 1 are shown in table 1:
TABLE 1
| Sample (I) | Particle size | Stability of |
| Example 1 | 90.3nm | 60 days |
| Example 2 | 83.2nm | 60 days |
| Example 3 | 78.4nm | 60 days |
| Example 4 | 110.7nm | 60 days |
| Example 5 | 108.2nm | 60 days |

| Comparative example 1 | 155.5nm | 50 days |
As can be seen from Table 1, the particle diameters of the liquid disperse dyes in examples 1 to 7 are smaller than that of comparative example 1, which indicates that the dispersibility of the liquid disperse dyes in examples 1 to 7 is better than that of comparative example 1, wherein the particle diameters of the liquid disperse dyes in examples 1 to 3 decrease with the increase of the auxiliary agent, which indicates that the auxiliary agent plays an important role in the dispersion; the particle size increase in example 4 is probably due to the fact that the increase of the dye causes the dye to have poor flowability in the dispersion system and the collision probability is reduced; in example 5, the particle size was increased due to the absence of the grinding aid; example 6 compared with example 3, the dispersant is not added twice, the influence on the particle size is not great, but the stability is reduced; example 7 compared to example 3, the dispersant was added at one time, and the particle size was slightly reduced, but the stability was reduced. The liquid disperse dyes of examples 1 to 5 were stored at rest (20 ℃ C.) for 60 days, no precipitation occurred, whereas the liquid disperse dyes of examples 6 to 7 and comparative example 1 were significantly precipitated.
