PROBLEM TO BE SOLVED: To provide a method of dyeing sewn products evenly with impressive appearance. SOLUTION: (1) A method of dyeing fiber product made of disperse dye- dyeable fiber by using supercritical carbon dioxide as a dyeing medium, when the fiber is dyed with disperse dyes. (2) A method of dyeing fiber products wherein the disperse dye-dyeable fiber is polyethylene terephthalate, polybutylene terephthalate or polytrimethylene terephthalate synthetic fiber or cellulosic fiber that is made disperse dye-dyeable. (3) A method of dyeing fiber products wherein the fiber products are dyed, as they are in fixed states. (4) A method of dyeing fiber products wherein the temperature of the supercritical carbon dioxide is 5 deg.C higher than the critical point of the carbon dioxide on dyeing or the temperature and pressure of the supercritical carbon dioxide are >=60 deg.C and >=15 MPa on dyeing, respectively.
