Description
Technical Field
The invention relates to the technical field of dyes, in particular to a black liquid disperse dye with high fastness in a nanometer level and a preparation method thereof.
Background
The traditional printing and dyeing industry adopts powdery, granular and other solid dyes, which not only can cause dust pollution when mixing pulp or preparing dye liquor, but also can be easily adhered to a dosing tool or suspended in dye liquor foam, and large granular dyes which are not dispersed or dissolved (especially dyes with small solubility and poor dispersion performance, poor wettability and dispersion performance) are easy to generate defects when printing or dyeing because of being adhered to each other to form lumps, thereby seriously affecting the product quality. In order to solve the technical defects of the solid dye, liquid disperse dyes are developed in the prior art, but for black liquid disperse dyes, particularly black liquid disperse dyes based on three primary color dye components, the combination force of the dyes and fibers is poor due to the high proportion of a dispersing agent, so that the loose color of the dyes on the surfaces of the fibers is increased, reduction cleaning, soaping or water washing is needed to remove the loose color after dyeing, a large amount of water resources are wasted, and a large amount of high wastewater discharge is generated. Moreover, the color fastness is poor, the color fading is serious in the subsequent washing, and the color vividness of the fiber after washing is poor. With the increasing requirements of the printing and dyeing industry on energy conservation and emission reduction, the composition proportion and the preparation method of the black liquid disperse dye based on the three primary color dye components are in urgent need of improvement.
Disclosure of Invention
In order to solve the defects of the prior art, the invention provides a black liquid disperse dye with high fastness at a nanometer level.
The technical scheme of the invention is realized as follows:
a nano-grade high-fastness black liquid disperse dye comprises: disperse blue 79, disperse orange 44, disperse violet 93, a dispersing agent, a leveling agent, an antifreezing solution, a foam stabilizer, a penetrating agent, a tank cleaning agent, a bactericide, a defoaming agent and water;
in the black liquid disperse dye, the weight percentages of the components are respectively as follows: disperse blue 79:1% -40%, disperse orange 44:1% -40% and disperse violet 93:1 to 40 percent of dispersant, 1.5 to 6 percent of leveling agent, 0.5 to 4 percent of antifreeze, 0.2 to 2 percent of foam stabilizer, 1 to 1.8 percent of penetrant, 0.15 to 0.3 percent of cylinder cleaning agent, 0.3 to 0.5 percent of bactericide, 1.8 to 2.5 percent of defoaming agent and the balance of water.
Further, the dispersant is at least one of MF, NNO, and sodium lignosulfonate.
Further, the leveling agents are: at least one of 0-25 of peregal and 0-15 of peregal.
Further, the penetrating agent is at least one of penetrating agent JFC, rapid penetrating agent T and high-temperature penetrating agent JFC-M.
Further, the antifreeze is ethylene glycol, the foam stabilizer is coconut oil fatty acid diethanolamide, the cylinder cleaning agent is ethylene glycol monobutyl ether, and the bactericide is isothiazolinone.
The invention also provides a preparation method of the black liquid disperse dye with the nanometer level high fastness, which comprises the following steps: firstly, sequentially adding water, a leveling agent, an antifreezing solution, a dispersing agent, a foam stabilizer, a cylinder cleaning agent, a penetrating agent, a bactericide and a defoaming agent into a pulping pot, then stirring while adding disperse blue 79, disperse orange 44 and disperse violet 93 to obtain a mixture, and finally pulping, emulsifying and ultrasonically sanding the mixture.
The inventor surprisingly finds that the nanometer-level high-fastness black liquid disperse dye prepared by the preparation method can obviously improve the color fastness. Presumably the reason for this is: each component is uniformly dispersed in the ultrasonic grinding and forms firmer binding force with water molecules, so that the content of free water in the dye is greatly reduced, good color yield is obtained, the permeation to the cloth is reduced, and the full sizing and bright color are facilitated.
Specifically, the mixture is sanded until the proportion of solid particles with the particle size of less than 1 μm in the mixture is not less than 97%, and then water is added to prepare the mixture with required strength.
Further, during pulping, the pH value of the mixture is controlled to be 5-6; when in sand grinding, zirconium beads with the diameter of 0.4-0.6mm are adopted, the filling rate of the zirconium beads is 40-50%, and the rotating speed of a sand grinder is 1200-1300r/min.
Further, the ultrasonic frequency is 90KHz-120KHz.
The invention reasonably selects various components, scientifically mixes the content of the components, and adopts an ultrasonic grinding mode to prepare the nano black liquid disperse dye with the solid particle ratio of less than 1 mu m being not less than 97 percent, and the components are mutually compatible and have synergistic action, so that the black liquid disperse dye is not easy to permeate, bright and uniform in color, high in washing fastness, good in lifting force and free from washing.

From a comparison of examples 1 to 5 with the prior art, it can be seen that: the nano-grade high-fastness black liquid disperse dye provided by the invention has excellent blackness, good friction color fastness, washing color fastness, light color fastness and heat color fastness, is free from washing, effectively solves the problems of high wastewater discharge, high pollution and high water consumption in the printing and dyeing industry, saves energy, reduces emission, reduces cost and has high cost performance.
As can be seen from example 1 and comparative example 1, whether the ultrasonic wave is adopted during grinding has obvious influence on the rubbing color fastness, washing color fastness and light fastness of the product; as can be seen from example 1, comparative example 2 and comparative example 3, the rubbing color fastness, washing color fastness and light fastness of the product are not improved when the ultrasonic frequency is more than 120KHz or less than 90KHz during grinding. Good color yield, color fastness and washing fastness are facilitated only when the ultrasonic frequency is between 90KHz and 120KHz.
From example 1, comparative example 4, and comparative example 5, it is understood that when the solid particles having a particle size of less than 1 μm are ground to a ratio of 90% to 95% in the mixture, the difference between the crockfastness, the water washing fastness, the light fastness, and the heat fastness is not large, and when the mixture is broken by 97%, the crockfastness, the water washing fastness, the light fastness, and the heat fastness are remarkably improved.
