Abstract

An aqueous dispersion approximately comprising by weight PA0 (A) 1-30 parts by weight of a polyether-siloxane, cross-linked via alkylenoxy bridges, of the general formula ##STR1## in which Z is divalent alkylenoxy radical with 2-8 C atoms, PA1 R is a polyether radical, PA1 x is an integer between 2 and 25, and PA1 y is an integer between 1 and 9, PA0 (B) 1-40 parts of a high-molecular polyethylene with an average molecular weight of above 15,000-50,000, PA0 (C) 1-10 parts of an anionic emulsifier, PA0 (D) 0-15 parts of a non-ionic emulsifier, and PA0 (E) 2-97 parts of water. has been found to be particularly stable and useful in the finishing of textiles.
