The present invention relates to a method for producing dyed polyester fibers (C) from a terephthalate polyester (A), at least one additive (B) containing polyester, and optionally at least one component (G). The additive contining polyester can be obtained by condensing the monomers of an aliphatic 1, ω -dicarbolic acid and an aromatic 1, ω -dicarbolic acid. Chain lengtheners (V) are optionally also used in the production of the additive (B) containing polyester. The components (A, B) and optionally (G) are mixed, melted in an extruder, and extruding by means of spinnerets for generating fiber. Said polyester fibers (C) are preferably used in the production of dyed textile material webs (F). |
