The present application is directed to a method of waterless processing of textile materials using supercritical fluid, including the use of supercritical fluid to dye the textile materials, the use of supercritical fluid for a pre-processing procedure of cleansing the textile materials, and the use of supercritical fluid to wash off unfixed dyes and cleansing of the textile materials and to perform the post-processing procedure of adding functional materials after the use of supercritical fluid to dye the textile materials. The present application provides an integrated technology of pre-processing, dyeing and post-processing of textile materials using supercritical fluid. At the same time, cleansing and dyeing are performed which effectively raises the efficiency.
