In on bath eyeing system of the spandex/PET fibers with disperse dyes(C.I.Disperse Red 60 = Red 60, C.I.Disperse Yellow 54=Yellow 54), its adsorption and edsorption behaviors on each component were examined. The spandex fiber structure was looser than PET fiber structrue. Therefore the spandex fiber easily adsorbed and desorbed disperse dyes than PET. When the spandex/ PET fibers were dyed with disperse dyes in one bath, uptake of the Yellow 54 on the spandex was lower than that of the Red 60. The color difference between spandex and PET was not significant in one bath. When the spandex/PET fibers were dyed in one bath, the color difference was more distinguishable between spandex and PET with the less part of spandex.
