Problems solved by technology

So far, the color of most textiles, especially non-woven products, is mostly obtained through the way of pigmentation, and the photonic crystal color-producing structure is constructed on the surface of the non-woven fabric to obtain bionic structural color to obtain structural color-producing non-woven products. There are very few studies and reports

Abstract

The invention belongs to the technical field of photonic crystal preparation, and discloses a method of preparing a bionic photonic crystal structure color-generating textile. According to the method,an adhesive layer is arranged between a photonic crystal color-generating structure layer and a textile substrate to obtain the photonic crystal color-generating structure textile with high stability. Self-crosslinking polyacrylate is used as an adhesive to bond the photonic crystal color-generating structure layer to the textile substrate, so that the adhesion between the photonic crystal color-generating structure layer and the textile substrate is enhanced, and the stability and firmness of the photonic crystal color-generating structure layer are significantly improved.

Description

technical field [0001] The invention belongs to the technical field of photonic crystal preparation, specifically relates to a preparation method of functional textiles, and more particularly relates to a preparation method of color-producing textiles with a bionic photonic crystal structure. Background technique [0002] At present, the coloring of textiles is mainly based on pigmentation, that is, coloring is mainly produced by applying colorants such as dyes or pigments, and its mechanism involves mechanisms such as electronic transitions. With the advancement of research, in recent years, research and reports on the construction of special physical structures on the surface of textiles and the use of interactions between them and visible light, such as diffraction, interference and scattering, to obtain bionic structural colors are common. There are obvious differences between bionic structural color and pigment color, and structural color can often produce some special ...
