Problems solved by technology

However, so far, when using digital jet printing to build photonic crystal color-producing structures on textile substrates, there are limitations such as limited printing equipment, especially in the lack of adaptation between jet printing nozzles and photonic crystal structure color-producing inks Sex, resulting in poor printing effect

Embodiment 1

[0040]At room temperature, to 25% (in terms of solid content) particle size is 240nm, monodispersity index (PDI) is 0.05 polystyrene microspheres (PSt) colloidal microspheres, add successively account for 5% of the total mass of colloidal microspheres Structural stabilizer self-crosslinking water-based polyacrylate, 1% surfactant sodium dodecyl sulfate (SDS) and 2% thickener sodium alginate (SA), then heated and stirred at 70°C for 20min; The above prepared finishing solution was stirred at 10000r / min for 30min, then placed in a gravure printing machine, and pattern printing was carried out on the black polyester fabric base material, and the printed black polyester fabric was taken out, and then heat-baked at 80°C for 60s Bright and gorgeous, highly stable turquoise photonic crystal structure color-producing textiles can be obtained.

Embodiment 2

[0042] At room temperature, 30% (in terms of solid content) of silicon dioxide (SiO) with a particle size of 210 nm and a monodispersity index (PDI) of 0.06 2 ) in the colloidal microspheres, sequentially add the structure stabilizer self-crosslinking water-based polyurethane accounting for 3.5% of the total mass of the colloidal microspheres, 3% of the surfactant alkylphenol polyoxyethylene ether (OP-10) and 1% of the thickener Carboxymethyl cellulose (CMC), then heated and stirred at 70°C for 20 minutes; the above prepared finishing solution was stirred at a speed of 10000r / min for 30 minutes and then placed in a gravure printing machine, and pattern printing was carried out on a black silk fabric substrate. Take out the printed black silk fabric, and heat-bake it at 80°C for 60 seconds to get bright and gorgeous, highly stable color-producing textiles with blue photonic crystal structure.

Embodiment 3

[0044] At room temperature, to 40% (in terms of solid content) particle size is 350nm, monodispersity index (PDI) is 0.02 poly (styrene microspheres-methacrylic acid) (P (St-MAA)) colloidal microspheres Add successively the structural stabilizer self-crosslinking water-based polyacrylate accounting for 2% of the total mass of the colloidal microspheres, 2% of the surfactant sodium lauryl polyoxyethylene ether sulfate (AES) and 1.5% of the thickener glycerol Alcohol (GL), and then heated and stirred at 70°C for 20 minutes; the above prepared finishing solution was stirred at 10000r / min for 30 minutes, then placed in a gravure printing machine, and pattern printing was carried out on the black cotton fabric substrate, and it was taken out after printing. After the black cotton fabric has been baked at 80°C for 60 seconds, a bright and colorful, highly stable magenta photonic crystal structure color-producing textile can be obtained.

Abstract

The invention belongs to the technical field of photonic crystal preparation, and particularly provides structural chromogenic finishing liquid for preparing a high-stability photonic crystal and application of the structural chromogenic finishing liquid in preparation of a patterned high-stability photonic crystal chromogenic structure on a textile substrate. By preparing the structural chromogenic finishing liquid composed of colloidal microspheres, a structural stabilizer, a surfactant and the thickener, the structural chromogenic textile which is bright in color, obvious in iridescence effect and good in durability can be rapidly obtained. The novel-structure chromogenic finishing liquid effectively overcomes the defects that existing photonic crystals are prone to falling off and unstable, can guarantee the durability of the structural color of a fabric, and has the advantages of being easy to implement, low in cost, environmentally friendly and good in universality.

Description

technical field [0001] The invention belongs to the technical field of photonic crystal preparation, and in particular relates to a structural color-generating finishing solution for preparing patterned photonic crystals with high stability and its application. Background technique [0002] Photonic crystals are a type of artificially designed and manufactured crystals with periodic dielectric structures on the optical scale. The most fundamental feature is that they have photonic band gaps. By controlling the propagation of photons in the forbidden bands, colorful structural colors can be obtained. The photonic crystal structure does not need dyes or pigments to produce color, which is in line with the concept of green environmental protection and has certain application prospects in the field of textile dyeing and finishing. [0003] At present, there are many studies and reports on the realization of textile coloring by using colloidal microspheres as the basic structural...
