Description

Preparation and application of dye-doped nanometer microsphere structure color-generating ink for textile digital jet printing
Technical Field
The invention relates to a digital jet printing technology of textiles, in particular to a preparation method of dye-doped nanometer microsphere structure color-generating ink and a method for constructing photonic crystal structure color generation by utilizing the dye-doped nanometer microsphere structure color-generating ink to perform digital jet printing on textiles.
Background
Photonic Crystals (PCs) belong to photon forbidden band materials and are a structural color generation mode commonly existing in nature. When the visible light wave band (380-780nm) falls into the specific forbidden band of the photonic crystal, the photonic crystal can selectively reflect the light forbidden to propagate in the forbidden band, the reflected light forms coherent diffraction on the surface of the photonic crystal with the periodically arranged structure, and human eyes can see gorgeous structural color. The way of constructing structure photon crystals on textiles by adopting microsphere dipping self-assembly technologies such as gravity settling and vertical settling is frequently reported, but the problems of long assembly time, material waste, incapability of positioning, assembly and coloring according to requirements and the like exist, and fabrics used for self-assembly in the report are required to be dyed into black in advance, so that the process flow and time are obviously further increased.
The invention prepares the dye-doped nano microsphere ink, uniformly disperses the dye among nano microsphere liquid, and applies the dye on the textile in a digital jet printing mode according to the needs. Under certain conditions, the nano-microspheres can be self-assembled on the textile, and the dye can be dyed and fixed, namely the textile can be used for constructing the structural color of the photonic crystal while coloring the pigment, and the textile is not required to be dyed with the ground color in advance. When the visible light wave band falls into the photon forbidden band, the un-forbidden light will be partially or completely absorbed by the dye on the textile, and the reflected light can still form diffraction on the surface of the colloid microballoon which is periodically arranged to present colorful structural color.
The invention provides a preparation method of dye-doped nano microsphere ink and application of the dye-doped nano microsphere ink to the technical field of textile structure color generation in a digital jet printing mode.
