Abstract
A process for dyeing or treating textile fibre materials with foam, which process comprises applying to the textile fibre materials a foamed aqueous composition which, in addition to containing the dye (or fluorescent whitening agent) or the fabric finishing agent, contains a foamable system comprising water and PA0 (A) a fatty acid/alkanolamine reaction product or an alkylene oxide adduct of this reaction product and at least two of the following components PA0 (B) a fatty alcohol which is optionally mono-, di- or triethoxylated and which contains 8 to 22 carbon atoms in the fatty alcohol radical, PA0 (C) an adduct of 5 to 15 moles of ethylene oxide and 1 mole of a fatty alcohol or a fatty acid, each containing 8 to 22 carbon atoms, or 1 mole of an alkylphenol containing a total of 1 to 12 carbon atoms in the alkyl moiety, and PA0 (D) an acid ester, or a salt thereof, of a polyadduct of 2 to 15 moles of ethylene oxide and 1 mole of a fatty alcohol containing 8 to 22 carbon atoms. The composition is then applied to the textile fibre materials, which are subsequently subjected to a heat treatment, e.g. by thermofixation, in the temperature range from 120.degree. to 210.degree.
