The present invention relates to a process for the preparation of a spinnable composition (sC) by mixing at least one terephthalate polyester (A), at least one aliphatic-aromatic polyester (B), at least one oligomer (C) and optionally at least one additive (D). Moreover, the present invention relates to the spinnable composition (sC) obtained by this process, a process for the preparation of polyester fibers (PF) by extruding the spinnable composition (sC) through at least one spinneret, the polyester fibers (PF) obtained by this process, textile materials (T) comprising the polyester fibers (PF) a process for dying the textile materials (T), and the use of the oligomer (C) for the improvement of the rheology and/or the dyeability of a composition comprising at least one terephthalate polyester (A) and at least one aliphatic aromatic polyester (B).
