Abstract

The invention relates to the field of coloring of structural colors of flexible mediums and provides a structural color preparation device and method for a flexible medium. The device comprises a primary coating system and a fine processing system, the primary coating system comprises a first electrostatic generator unit and multiple spray nozzle assemblies and is used for alternately spraying andcoating TiO2 liquid mist with positive charges and SiO2 liquid mist with negative charges on the surface of fabric, and photonic crystal even-thickness thin film is formed on the surface of the fabric to obtain primary coated fabric; the fine processing system comprises a computer, a control module, a second electrostatic generator unit and multiple spray nozzle assemblies, the control module sprays TiO2 aqueous solution droplets and SiO2 aqueous solution droplets on the surface of the primary coating fabric according to signals transmitted by the computer, photonic crystal layers with different thicknesses are formed on the surface of the primary coated fabric, and accordingly coloring of colorful structural colors of the fabric is achieved. The device is high in efficiency, due to participation of the positive charges and the negative charges, bonding of all coatings is more compact, and the coatings do not easily fall off.

Description

technical field [0001] The invention relates to the field of coloring, in particular to a device and method for preparing structural color of a flexible substrate. Background technique [0002] The coloring of textiles is usually produced by pigments. During the dyeing and finishing process, a large amount of clean water is required, the added chemical dyes and auxiliaries have poor biodegradability, high free formaldehyde content, and excessive heavy metal ion content, causing environmental pollution and hindering human health. Structural color is the color produced by selective reflection caused by dispersion, scattering, interference and diffraction. It does not need to add chemical dyes, choose environmentally friendly photonic crystals, and reasonably arrange the microstructure of photonic crystals to obtain the required color. This is a kind of The non-polluting way of producing color has attracted more and more attention. [0003] The patent application number is: ZL...
