Summary:An aqueous formulation which contains (a) 10-50% of lecithin, (b) 5-40% of an oxyethylated carboxylic acid of the general formula R-CO-O-(CH2-CH2-O-)nH I in which R represents a saturated or unsaturated alkyl radical with 11-21 carbon atoms and n represents a number between 4 and 12, (c) 5-40% of an oxyethylated alcohol of the general formula R'-O-(CH2-CH2-O-)mH II in which R' represents a saturated or unsaturated alkyl radical with 12-20 carbon atoms and m represents a number between 10 and 30, and (d) 0-20% of an alkanol with 1-3 carbon atoms, of a glycol with 2-4 carbon atoms or alkyl ethers thereof with 1-4 carbon atoms, or of diethylene glycol, triethylene glycol or tetraethylene glycol or alkyl ethers thereof with 1-4 carbon atoms, is used for dyeing woven goods and knitted goods of polyester fibres or fibre mixtures containing polyester fibres with disperse dyestuffs in an aqueous liquor at temperatures of 95 DEG -140 DEG C.
