Thermally stable textile lubricants suitable for spinning finishes based on polyol fatty acid esters, into which esters of thiocarboxylic acids corresponding to general formula (I) and/or (II): n n R.sup.1 --S--R.sup.2 --COOH (I) n n n HOOC--R.sup.3 --S--R.sup.4 --COOH (II) n n in which R 1 , R 2 , R 3 and R 4 may be the same or different and represent an alkyl, cycloalkyl, aryl or alkaryl group containing 1 to 22 carbon atoms, are introduced to increase thermal stability, are distinguished by excellent thermal stability. |
