Abstract

Process for the production of voluminous or textured polyester yarns, characterized in that it comprises producing a polyester yarn by spinning by extrusion and continuous drawing by collecting the yarn at a linear speed higher than 04,700 m/min, the yarn thus obtained having a crystallinity greater than 30% but less than 60%, and a residual draft not greater than 1.2, and subjecting said yarn to a false twist and fixation treatment, in which the yarn is not subjected to any action involving a subsequent draft effect that can be noticed.
