s2, stirring the liquid crystal homogeneous emulsion at a high temperature, and cooling and standing to obtain the liquid crystal structure pigment with the lyotropic liquid crystal emulsified coating on the particle surface;
s3, putting the liquid crystal structure pigment into a grinder for grinding and dispersing, adding a dispersing agent, grinding together with the dispersing agent, and obtaining the liquid crystal structure pigment with high light fastness after finishing grinding.

As a further description of the above technical solution:
in the step S1, the composite liquid crystal finishing agent is one or more of glucosides, sucrose esters, glyceride, phosphonate esters and lecithin.
As a further description of the above technical solution:
in the step S1, the auxiliary emulsifier is one or more of a surfactant containing various acid radicals and long carbon chain fatty alcohol.
As a further description of the above technical solution:
in the step S1, the homogenizing and emulsifying rotating speed is 2000-8000r/min, and the homogenizing time is 2-10min.

On the other hand, the invention also provides application of the liquid crystal structure pigment in the fields of pigment printing, ink-jet printing, food coloring and painting ink.
In summary, due to the adoption of the technical scheme, the beneficial effects of the invention are as follows:
1. in the invention, after the prepared liquid crystal structure pigment is used for coloring the textile, the K/S value of the textile is even slightly improved compared with that of a common pigment printing textile, because part of finishing agent has a deepening effect. Meanwhile, compared with common pigment printed fabrics, the color fastness to sunlight of the liquid crystal structure pigment is greatly improved, so that the application range of the pigment with poor color fastness to sunlight is enlarged.
2. Most organic pigments have bright color light and excellent color development performance, but partial scarce color spectrum pigments have higher symmetry degree of molecular structures, and certain groups in the structures are activated by selective absorption of light in different wave bands, so that substitution and ring opening reactions are easy to occur, and the pigments fade. Compared with the common pigment, the prepared lyotropic liquid crystal emulsion coated liquid crystal structure pigment with high light fastness has excellent light fastness and can be applied to the coloring of various textiles.
3. In the preparation process of the pigment with the liquid crystal structure, the composite liquid crystal finishing agent cooperates with the auxiliary emulsifier to form a lyotropic liquid crystal emulsion coating structure on the surface of the pigment particles, so that the charge property of the surface of the pigment is changed, and the pigment is dispersed more uniformly. The pigment is easy to generate substitution reaction and ring-opening reaction after absorbing light energy and being activated, and the finishing agent with negative electricity on the surface of the pigment can effectively prevent the reaction. Starting from the sun-drying and fading reaction mechanism of the pigment, the liquid crystal structure inhibits or blocks the progress of the fading reaction, and can enhance the sun-drying resistance of the pigment. By the method, a series of liquid crystal structure pigments with high light fastness can be obtained.
