The invention relates to a disperse dye capsule/active dye polyester-cotton fabric one-bath process dyeing technology. Research on the disperse dye capsule/active dye polyester-cotton fabric one-bath process dyeing technology is performed from the points of selection of an active dye influencing the dyeing effect of the polyester-cotton fabric one-bath process, the bath ratio, the heating speed, the warm-keeping time and other factors, and an optimum dyeing technology is obtained. Compared with a routine one-bath method, under the premise of avoiding a reducing cleaning process, the obtained color is deeper than that of dyed fabric by using a routine method employing the reducing cleaning process, and the disclosed technology has the biggest advantage of preventing reducing cleaning from destroying the active dye; and the dry/wet friction fastness, and the staining fastness and the discoloring and fading grade at 60 DEG C of the dyed fabric are relatively high, and the grades are all 4 grade or more.
