A method of treating, especially dyeing, whitening and/or finishing, textile fabrics, in particular carpets, with an aqueous foamed composition which, in addition to containing dye or fluorescent whitening agent and/or finishing agent, contains a foam stabilizer, a foam regulator, and, optionally, other assistants. The aqueous composition employed contains (a) 1 to 4 g/liter of an anionic or non-ionic surfactant, or a mixture thereof, as foam stabilizer, and (b) 0.1 to 1 g/liter of an oxyalkylene-siloxane copolymer as foam regulator, said foam having a blow ratio of (6 to 20).1, applying said foam continuously, in the form of at least one layer, to the textile fabric, if desired vacuuming said fabric to effect penetration of the layer of foam through the fabric, and subsequently subjecting the fabric to a steam treatment. Level dyeings with good penetration and/or excellent finishes are obtained on the treated textile fabrics. |
