This study developed a one-step spraying method using an aqueous solution of SiO2 particles to prepare SiO2/PET fabrics with saturated and uniform structural colors. The color brightness and uniformity were significantly improved by optimizing the treatment temperature, pH of the colloidal solution, and by introducing a small amount of ethanol. This method would promote the applications of structural colored fabrics because using water would reduce both environmental pollution and production cost.

Key words: spray, SiO2 colloids, photonic crystal, polyester fiber, structural colored fabric
