Abstract
The present application provides a fabric coloring method and a colored fabric, where the fabric coloring method includes: performing radiation drying on a base cloth; sequentially forming an adhesive layer and at least one color-generating layer on a surface of the base cloth after the radiation drying by vacuum deposition, where the adhesive layer contains at least one of Ti, Cr, Si and Ni, and a thickness of the adhesive layer ranges from 1 nm to 2000 nm; the color-generating layer contains at least one of Al, Ti, Cu, Fe, Mo, Zn, Ag, Au, and Mg, and the total thickness of the color-generating layer ranges from 1 nm to 4000 nm. The fabric coloring method can not only produce rich colors and make the colored fabric have good color fastness, but also reduce the sensitivity of color of the colored fabric to thickness of the film, thus improving the industrial operability.
