The present invention relates to a process for producing dyed mixed fibres (D-MF), dyed mixed fibre yarns (D-MY) and/or dyed mixed fibre textile fabrics (D-MT) in which mixed fibres (MF), mixed fibre yarns (MY) and/or mixed fibre textile fabrics (MT) comprising at least one polyester fibre (PF) and at least one further fibre (FF) are simultaneously contacted with at least two different dyes (D1) and (D2) at a temperature T<130° C. The at least one polyester fibre (PF) comprises 80 to 99.5% by weight of at least one terephthalate polyester (A), 0.5 to 20% by weight of at least one aliphatic-aromatic polyester (B) and 0 to 5% by weight of at least one additive (C), wherein the % by weight are based in each case on the total weight of components (A), (B) and optionally (C). Moreover, the present invention relates to the dyed mixed fibres (D-MF), the dyed mixed fibre yarns (D-MY) and/or the dyed mixed fibre textile fabrics (D-MT) obtained by this process.
