PROBLEM TO BE SOLVED: To provide a flame-retardant polyester fabric which has a chinchilla- like appearance quality, a soft touch and a rich design property and can not be realized by conventional flame-retardant polyesters.;SOLUTION: This method for dyeing the flame-retardant polyester fabric having a rich design property and at least partially containing polyester multifilament yarns prepared by melt-spinning a copolyester containing a phosphorus compound represented by the general formula [R is a monovalent ester- forming functional group; R2 and R3 are each identically or differently a halogen, a 1 to 10C hydrocarbon or R1; A is a divalent or trivalent organic residue; (n1) is 1 or 2; (n2) and (n3) are each an integer of 0 to 4] and having a phosphorus atom content of 500 to 50,000 ppm, is characterized by subjecting the polyester fabric to a wet heat relaxing treatment comprising quickly heating from a lower temperature by 20°C than a fiber shrinkage-starting temperature obtained from the heat shrinkage stress curve of the multifilament yarns to a higher temperature by 30°C than the fiber shrinkage-starting temperature at a rate of +5 to +10°C/min.;COPYRIGHT: (C)2003,JPO
