A process is provided for producing staple fibers that may be used in the formation of carpets from poly(trimethylene terephthalate). Poly(trimethylene terephthalate) may be melt spun to form filaments. The melt spun filaments may then be cooled with a liquid having a temperature of at most 20° C. The cooled filaments may then be drawn, and the drawn filaments may be cut into staple fibers. The resulting staple fibers have highly uniform physical characteristics such as denier, tenacity, and elongation at break that render the fibers particularly useful for forming carpets.
