Abstract: A process for producing polyester fiber highly suitable for a raw yarn for a woven or knitted fabric, having a residual elongation of not higher than 60%, a Young's modulus of 60 to 100 g/d, a boiling water shrinkage of 4 to 10% and a dry heat shrinkage of 5 to 12%, the peak stress temperature in a dry heat shrinkage stress curve of said fiber being lower than 100.degree. C. The process comprises melt spinning a thermoplastic polyester through a spinneret into a filament and taking up the filament after solidifying the spun filamentary polymer, characterized in that the whole process from spinning through take-up is carried out without heating the filament, the filament is subjected to stretch treatment at a stretch ratio of not more than 20% after the solidification of the filament but before take-up, and take-up is carried out at a take-up speed of not less than 5,000 m/min.
