Cationic dyeable polyester(CDP) fabric was annealed at varying temperatures range from $120^{circ}C$ to $220^{circ}C$ for 1, 3, and 5 min under tension. Dyeing rates of CDP fabrics were measured with cationic and disperse dyes at $100^{circ}C$ and $120^{circ}C$ in water system. Also X-ray diffraction pattern, DSC thermograms and dyeability of fabric with cationic and disperse dyes were investigated. The intensities of X-ray diffraction peaks of annealed fabric were increased with increasing in annealed temperature, and peak became sharp with heat setting temperature. The apparent color depth (K/S) of CDP fabric initially decreased with increase of heat-setting temperature up to $160~180^{circ}C$ and then increased at higher temperature. The shearing modulus(G) and surface roughness were increased with annealing temperature.
