The effects of temperature in fiber drawing process on two different polyesters, undrawn yarn (UDY) and partially oriented yarn (POY), were investigated. Drawing temperature was varied from the glass transition temperature ($T_{g}$) of polyester (7$0^{circ}C$) by 4$^{circ}C$ intervals up to 94$^{circ}C$ to study the relationship with structural variations, such as initial modulus, orientation, crystallization, and fiber evenness. Furthermore, we also tried to delineate the dyeing properties of polyester fibers which had been drawn at different temperature. results indicated that the increase in drawing temperature enhanced fiber evenness in drawing of POY, while the opposite trend was shown in the case of UDY. In both cases, the dye exhaustion was not varied and the dyeing rate was slightly increased with the drawing temperature.
