Abstract
A cationic dye-dyeable polyester resin composition comprising a cationic dye-dyeable polyester resin and a melt viscosity depressant. Addition of the melt viscosity depressant to the cationic dye-dyeable polyester resin reduces the melt viscosity of the resin without decreasing the intrinsic viscosity thereby making the resin melt-spinnable. A cationic dye-dyeable polyester fiber with high strength can be obtained from the polyester resin composition.
