Abstract
Abstract Fabric softeners which result in an improved rewettability of the textile material treated with the same and which are present in the form of an aqueous solution or dispersion containing from 3 to 15% by weight of one or several quaternary ammonium compounds and from 0.5 to 1.5% by weight of a compound of the formula ##STR1## in which R 4 is alkyl or alkenyl of from 4 to 20 carbon atoms, cyclohexyl or aryl optionally substituted by alkyl groups, x and y are hydrogen or methyl, but are not methyl at the same time, n is a number of from 0 to 20, Z is a group of formula --(CH 2 ) m COOMe, --SO 3 Me or --PO 3 Me 2 m is an integer of from 0 to 3, and Me is an alkali metal or ammonium ion, as well as optionally further common auxiliaries and additives.
