Problems solved by technology

If you want to obtain colored asymmetric wettability textiles, you usually have to go through dyeing first, and then finish finishing. In this way, there are not only many operating procedures, but also each process will generate energy consumption.
If the two sides of the textile are required to have different colors or patterns, the processing will become more complicated

Abstract

The invention discloses a structural chromogenic textile with asymmetric wetting characteristics as well as a preparation method and application thereof. The preparation method comprises the steps of1), configuring structural chromogenic ink I comprising hydrophobic colloidal microspheres and structural chromogenic ink II comprising hydrophilic colloidal microspheres; 2) coating the first surfaceof a textile base material with the structural chromogenic ink I and performing curing treatment to obtain the textile base material with a hydrophobic photonic crystal layer on the first surface; and 3) coating the second surface of the textile base material treated in the step 2) with the structural chromogenic ink II, and performing curing treatment to obtain the structural chromogenic textilewith the asymmetric wetting characteristics. The preparation method is simple and convenient in process, easy to implement and high in universality, and integration of textile coloring and asymmetricwettability finishing is realized; and the front surface and the back surface of the structural chromogenic textile prepared through the method have different wetting properties, and the structural chromogenic textile is bright, natural, deep and lifelike in color and has the advantages of being ecological and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of functional textiles, and in particular relates to a structural color-producing textile with asymmetric wetting properties and a preparation method and application thereof. Background technique [0002] According to the source of color, it can be divided into pigment color and structural color. Pigment color refers to the color formed by pigments such as dyes or pigments. The color-producing mechanism involves theories such as electronic transitions, and the corresponding color-producing method is called chemical coloration. After prolonged exposure to the sun, some pigments often fade, and some dyes or pigments have hidden dangers such as carcinogenicity and pollution. Structural color refers to the visual effect formed by the interference, diffraction and scattering of the special physical structure of the object itself and light. Butterfly wings, peacock feathers and soap bubbles in nature are all typi...
