Abstract

The invention relates to a method for preparing a one-dimensional photonic crystal film on the fabric surface to realize a structural color. The method comprises preparation of titanium sol and silica sol and alternate forming of a titanium dioxide film layer and a silicon dioxide film layer on the fabric surface. The structural color can be formed on the fabric surface by adopting the method. The results show that variation of the surface color of the fabric treated by the method can be observed from different angles and the structural color effect is generated. The synthetic method and required production equipment are simple, are easy to realize industrial production and have great reference significance in reducing the environmental pollution of the dyeing industry. The prepared fabric dispenses with any dye to realize the structural color and has excellent optical property and good application prospect.

Description

technical field [0001] The invention belongs to the field of bionic coloring of textiles, in particular to a method for preparing a one-dimensional photonic crystal film on the surface of a fabric to realize structural coloring. Background technique [0002] In the dyeing and finishing process of textiles, a large number of dyeing and chemical additives that have an impact on the environment and hinder human health are used. They have poor biodegradability, high toxicity, high content of free formaldehyde, and heavy metal ion content exceeding the standard. These additives are discharged in the form of gas, liquid, and solid to pollute the environment and endanger human health. [0003] Bionic coloring is an ecological dyeing approach, which can be roughly divided into two categories: pigment coloring and structural coloring. Structural coloration produces color through light scattering, interference and diffraction. The beautiful colors of some animals, such as butterflies...
