摘　　要：For a better understanding of the feasibility of supercritieal fluid dyeing （SFD） and more available information for the process development, the experiments of dyeing PET textile with C.I. disperse red 60 （anthraquinone type） and C. I. disperse orange 25 （azo type） in supercritieal CO2 were carried out with a high-pressure dyeing apparatus at temperatures from 80 to 130℃ and pressure up to 31 MPa. The effect of operating conditions on color yield （K/S） was investigated in SFD experiment, and the optimum operating conditions for the above two disperse dyes were obtained as follows： the temperature 120℃, the pressure 25 MPa and the dyeing time 100 min. As compared with SFD, the conventional water dyeing （CWD） was carried out with the same dyes and textile. The results show that the better fastness, levelness and apparent color can be achieved in SFD and the SFD process has many significant advantages over the CWD process.For a better understanding of the feasibility of supercritical fluid dyeing(SFD)and more available information for the process development,the experiments of dyeing PET textile with C.I.disperse red 60(anthraquinone type)and C.I.disperse orange 25(azo type)in supercritical CO2 were carried out with a high-pressure dyeing apparatus at temperatures from 80 to 130℃ and pressure up to 31 MPa.The effect of operating conditions on color yield(K/S)was investigated in SFD experiment,and the optimum operating conditions for the above two disperse dyes were obtained as follows:the temperature 120℃,the pressure 25 MPa and the dyeing time 100 min.As compared with SFD,the conventional water dyeing(CWD)was carried out with the same dyes and textile.The results show that the better fastness,levelness and apparent color can be achieved in SFD and the SFD process has many significant advantages over the CWD process.
