| Abstract: | Based on solving the problems of large resource expenditure and severe contamination to environment,a new type of clean production technology,i.e.,supercritical CO 2 dyeing process,is introduced.The characteristics of supercritical fluids and supercritical CO 2 dyeing process are emphatically analyzed.The soluble and diffusible properties of disperse dyes in supercritical CO 2 are discussed.Moreover,the functions of the fibre's surface structure and its modification during dyeing process are summarized.Based on the above discussion,some viewpoints about the development of the supercritical CO 2 dyeing technology are presented. |
