Abstract

A preparation for finishing textile fibers or products comprising textile fibers is disclosed. The preparation is liquid and contains 0.5 to 80% by weight of a mixture of modified organopolysiloxane A and B in a ratio of A:B by weight of 10:1 to 1:1, with the proviso that organpolysiloxane A is a linear siloxane containing polyether groups and having at least 40 dialkylsiloxy units, to which are linked at least 2 polyether groups, each of which has a molecular weight of 600 to 4,000 and which comprises 40 to 100 mole percent of oxyethylene units, the remainder being oxypropylene units, the ratio of the number of dialkylsiloxy units to the number of polyether groups being greater than or equal to 8. The organopolysiloxane B is a linear siloxane containing quaternary ammonium groups with at least 20 dialkylsiloxy units, to which at least 2 quaternary ammonium groups are linked over carbon atoms, the ratio of the number of dialkylsiloxy units to the number of quaternary ammonium groups being greater than or equal to 10. The remainder of the preparation comprises water or a water miscible solvent. The preparation improves the handle of the finished fibers or fiber products while, at th…
