Abstract
Aqueous dispersions which are suitable for the treatment of fibre materials, in particular textile materials, contain a polysiloxane having on average at least two hydroxyl groups bound to one silicon atom each and one polysiloxane having on average at least one amido group in the molecule. If the amidopolysiloxane does not contain a primary amino group, a third polysiloxane containing at least one primary amino group in the molecule must be additionally present in the dispersion. The fibre materials treated with these dispersions have a pleasant soft handle and a low tendency to yellow. The dispersant content can be lower than in known dispersions of amido-functional polysiloxanes.
