Aq. dispersions (I) for finishing of fibre materials comprise quaternary cpd(s) with long-chain alkyl gp(s). (II), a copolymer of at least 4C alkyl acrylates (III), opt. an emulsifier (IV) different from (II), and opt. a hydrophilising silicone (V). (I) are mfd. by polymerisation of (III) in the presence of the other components. (II) contains at least one satd. or unsatd. at least 12C alkyl gp; (II) is a quaternary imidazolinium or ammonium deriv. (III) is based on 4-10C (esp. 4-8C) alkyl acrylate; 1000 g (I) contains 20-70 g (II), 20-80 g (co)polymer (III), and opt. up to 100 g (IV) w.r.t. (III); (V) is a hydrophilising poly(dimethylsiloxane), pref. contg. epoxy, polyethoxy, polypropoxy, or polyethoxy/propoxy gps. 1000 g (I) contains 5-70 g (V) (I) also contains usual textile processing aids. Pref. process uses 0.5-40 wt.% (w.r.t. total monomers) of vinyl acetate, acrylonitrile, or N-methylolacrylamide, opt. etherified with 1-4C alcohols.
