Procedure

A mercerised cotton fabric is padded with a dyeing liquor which contains, per liter, 30 g of the direct dyestuff C.I. No. 35,780 and 100 g of N-methylcaprolactam, squeezed off to a liquor pick-up of 80% and then dried for 2 minutes at 150°. It is then rinsed. A deep red dyeing is obtained. Comparably good results are obtained if instead of N-methylcaprolactam 100 g of N-hydroxyethyl-oxazolidone per liter or 150 g of N-methyloxazolidone per liter are used.
