Abstract

The invention provides a textile product rubbing-resistant structural coloration ink and a preparation method thereof. The preparation method of the textile product rubbing-resistant structural coloration ink combines reaction type photonic crystal microspheres and reaction type adhesives, so that during the later stage of self-assembly, photonic crystal can have bonding reaction with the adhesives to produce chemical bonds and further to improve the rubbing fastness of the photonic crystal and the base materials. The preparation method of the textile product rubbing-resistant structural coloration ink achieves grafting of photo-initiated reactive groups at the molecular level according to the characteristics of rigid gel microspheres and gel adhesives to greatly enhance intermolecular forces, thereby solving the problem of poor rubbing fastness and small coloration area of structural coloration textile products.

Description

(1) Technical field [0001] The invention relates to a friction-resistant structural color-generating ink for textiles and a preparation method thereof. (2) Background technology [0002] Structural color is a method of coloring due to the existence of the special structure of the object, which produces physical effects such as reflection, diffraction, and interference on light, thereby producing color. Therefore, the structural color can produce a series of diverse colors without dyes and pigments, which not only avoids environmental pollution in the production and application of the printing and dyeing industry, completely solves the problem of sewage discharge in the coloring process, but also saves a lot of water and electricity consumption. Favor of the industry. [0003] At present, photonic crystal microspheres are one of artificially prepared materials that can produce structural colors. Usually, the gravitational sedimentation method is used to make the monodisperse collo...
