Preparation of low-angle dependent structural color textiles via redispersion method
In order to study more green dyeing technique,a redispersion method to construct amorphous photonic crystal structures on textile surfaces has been proposed.Non-rainbow structural colors can be combined with textiles by scraping off the silica film after a primary gravity settlement and performing a secondary gravity settlement on the fabric after grinding.Experiments were performed on different tissue structures at different concentrations and volumes under self-assembly environments at different temperatures.The effects of temperature,concentration,volume and structure on the structure of amorphous photonic crystals were studied.The final result shows that when the concentration of silica suspension is 25 mg/mL and the volume is 2 mL,a better amorphous photonic crystal structure color fabric can be obtained by self-assembly at 40℃.Under the same experimental conditions,the more smooth the organizational structure of the selected fabric,the closer the yarn arrangement,the smaller the pores in the fabric,and the better the color effect of the final composition.
