ABSTRACT OF THE DISCLOSURE This invention provides a process for producing a variable denier filament. The process comprises the steps of generating two individual streams of molten polyester of fiber-forming molecular weight travelling at different velocities; converging the individual streams side-by-side to form a combined strem; quenching the combined stream to form a combined filament and withdrawing the filament from the combined stream at a rate of speed in excess of 2500 meters per minute. Also provided is a self-crimping yarn which comprises a plurality of polyester continuous filaments. The filaments of the yarn have non-round cross-sectional areas which vary substantially regularly along the lengths of the filaments from regions of large cross-sectional area to regions of small cross-sectional area, the variation in cross-sectional area being mole than ? 10% about a mean value. The regions of large and small cross-sectional area are out of phase from filament to filament to thereby form the self-crimping yarn and the polyester continuous filaments of the yarn are formed by the above process.
