Abstract
Abstract The invention relates to a process for washing and softening of textiles with the use of washing liquors with a definite content of (1) anionic and, optionally, nonionic tensides, (2) the adduct of 1 to 3 mols of a lower alkylene oxide, particularly ethylene oxide and/or propylene oxide, to an N-alkylated-alkanediamine with 2 to 6 carbon atoms in the alkane and an aliphatic hydrocarbon with 8 to 24 carbon atoms in the N-alkylated moiety, as a textile softener, and (3) builders, and agents for the performance of the process.
