The present invention relates to a process for producing dyed polyester fibers (C) from a terephthalate polyester (A), at least one polyester-containing additive (B) and optionally at least one component (G). The polyester-containing additive is obtainable by condensation of the monomers of an aliphatic 1,&#x3c9;-diol, of an aliphatic 1,&#x3c9;-dicarboxylic acid and of an aromatic 1,&#x3c9;-dicarboxylic acid. Optionally, chain extenders (V) are also used in the production of the polyester-containing additive (B). For fiber production, the components (A), (B) and optionally (G) are mixed, melted in an extruder and extruded through spinneret dies. These polyester fibers (C) are preferably used in the production of dyed textile fabrics (F).

Producing spinnable and dyeable polyester fibers

An aqueous paint formulation having an aqueous basecoat and an aqueous dispersion having an at least partially neutralized ethylene copolymer wax, wherein the ethylene copolymer wax contains as comonomers in copolymerized form (A) 12-40 wt % of an ethylenically unsaturated carboxylic acid of formula (I), (B) 60-88 wt % of ethylene, and (C) 0-10 wt % of a further comonomer; or the ethylene copolymer was contains as comonomers in copolymerized form (A') 5-50 wt % of a comonomer of formula (II), (B&#x2032;) 50-95 wt % of ethylene, and (C&#x2032;) 0-20 wt % of a further comonomer; wherein the ethylene copolymer wax comprising the comonomers (A), (B), and optionally (C) has a molecular weight Mof 10000 to 150000 g/mol, and the ethylene copolymer wax comprising the comonomers (A&#x2032;), (B&#x2032;), and optionally (C&#x2032;) has a molecular weight Mof 5000 to 40000 g/mol.
