Abstract (en)
[origin: EP0339179A2] Agent for finishing textile fibres or products consisting of textile fibres which contains 0.5 to 80% by weight of a mixture of modified organopolysiloxanes A and B in a weight ratio A : B of 10 : 1 to 1 : 1, the organopolysiloxane A being a linear siloxane containing polyether groups and having at least 40 dialkylsiloxy units, to which are bonded at least 2 polyether groups, each having a molecular weight of 600 to 4,000 and consisting of 40 to 100 mol% oxyethylene units, the remainder to 100 mol% being oxypropylene units, and the ratio of the number of dialkylsiloxy units to the number of polyether groups being >/= 8, and the organopolysiloxane B being a linear siloxane containing a quaternary ammonium groups and having at least 20 dialkylsiloxy units, to which siloxane at least 2 quaternary ammonium groups are bonded via carbon, and the ratio of the number of dialkylsiloxy units to the number of quaternary ammonium groups being >/= 10. <??>The agent improves the handle of the finished fibres or fibre products with simultaneous hydrophilisation. This improvement in handle is also achieved in the case of twisted open-end yarns. The finished fibres or fibre products can be readily redyed or overdyed. They have good antielectrostatic properties.
