Problems solved by technology

Although these self-assembly methods are simple, they have many shortcomings. Because they are usually realized by impregnating the substrate, there are problems such as long assembly time, waste of materials, and inability to position, assemble, and color as required.
In the field of textiles, there are few reports on obtaining photonic crystal structural colors on the surface of fabrics

Embodiment 1

[0030] (1) Accurately weigh 0.5 part (based on solid content) of self-made P(St-MAA) colloidal microsphere emulsion (particle size: 202nm, dispersion coefficient: 0.05), add 0.05 part of anionic surfactant SDS, deionize 100 parts of water, then add sodium carbonate solution to adjust the pH of the system within the range of 7-8 (add while stirring), and then disperse in an ultrasonic disperser for 15 minutes to obtain uniformly dispersed colloidal microsphere ink;

[0031] Note: For the preparation method of P(St-MAA) colloidal microspheres, please refer to the reference - Zhu Wen, Huang Fangting, Zhang Ming, Zhou Jian, Preparation and Characterization of Styrene / Methacrylic Acid Copolymer Microspheres, "Functional Materials" , 2012, 43(11): 1418-1424. The specific method is: prepared by soap-free emulsion polymerization, the monomers are styrene (St) and methacrylic acid (MAA); the initiator is potassium persulfate (KPS), and the mass ratio of the feed is: m (St): m(MAA):m(H...

Embodiment 2

[0036] Accurately weigh 0.8 parts of self-made P(St-MAA) colloidal microsphere emulsion (particle size: 253nm, dispersion coefficient: 0.04) (based on solid content), add 0.08 parts of anionic surfactant SDS, and 100 parts of deionized water , then add sodium carbonate solution to adjust the pH = 7-8 (add while stirring), and then disperse in an ultrasonic disperser for 15 minutes to obtain uniformly dispersed colloidal microsphere ink;

[0037] The conditions and methods of jet printing and self-assembly are the same as in Example 1.

Embodiment 3

[0039] Accurately weigh 1.2 parts (based on solid content) of homemade P(St-MAA) colloidal microsphere emulsion (particle size: 264nm, dispersion coefficient: 0.03), add 0.10 parts of anionic surfactant SDS, and 100 parts of deionized water , then add sodium carbonate solution to adjust the pH = 7-8 (add while stirring), and then disperse in an ultrasonic disperser for 15 minutes to obtain uniformly dispersed colloidal microsphere ink;

[0040] The conditions and methods of jet printing and self-assembly are the same as in Example 1.

Abstract

The invention relates to a textile digital printing technology, and in particular discloses colloidal microsphere ink for coloring a textile digital printing structure and application of the colloidal microsphere ink. The colloidal microsphere ink for coloring the textile digital printing structure is characterized in that the colloidal microsphere ink is prepared by uniformly dispersing a mixture mainly consisting of the following components in parts by weight: 0.5-1.5 parts of mono-disperse colloidal microsphere which is 200-400nm in grain size (in terms of solid content), 0.05-0.15 part of an anionic surfactant (dispersant), 0.05-0.5 part of a pH regulator (regulating pH to 7-8) and 100 parts of deionized water. The colloidal microsphere ink formula disclosed by the invention is specifically developed to adapt to performance of coloring the textile digital printing structure; to adapt to a requirement of the textile on ecological safety, various materials of the invention are non-toxic and tasteless; to adapt to a requirement of the textile on flexibility, an ultra-thin photonic crystal structural film is sprayed and constructed as required through digital technology, which rarely affects hand feeling of the textile.

Description

technical field [0001] The invention relates to a textile digital printing technology, in particular to a colloidal microsphere ink for producing color in the textile digital printing structure and an application thereof. Background technique [0002] At present, the main way of coloring textiles is to produce colors by applying colored substances (dyes or pigments) on textiles, while many organisms in nature produce colors with special physical structures, namely: structural coloration. The production of structural color does not require the existence of chemical colorants such as dyes and pigments, and its essence is the visual effect produced by special organizational structures on physical phenomena such as dispersion, scattering, interference and diffraction of light. [0003] Photonic crystals (PCs) are a class of photonic bandgap materials, and are one of the main causes of structural colors in nature, such as: peacock feathers, opals and other colorful and gorgeous c...
