Composition for oil- and/or water-repellent finishing of fiber materials

An aqueous composition containing at least the components A, B and C, wherein

• component A is a mixture containing at least the components A1 to A3, wherein component A1 is a paraffin wax, component A2 is a condensation product of an alcohol having 12 to 22 carbon atoms, an etherified polymethylol melamine and optionally a polyfunctional ethanolamine, which condensation product may additionally contain 0.05% to 1.5% by weight of an acid, and component A3 is water,
• component B is a mixture containing at least the components B1 to B3, wherein component B1 is a polyurethane which contains isocyanate groups and whose isocyanate groups are blocked and wherein the polyurethane is constructed from an aromatic or aliphatic diisocyanate, wherein the diisocyanate was reacted with a diol having 2 to 6 carbon atoms, a trihydric aliphatic alcohol and an N-alkylated diethanolamine or triethanolamine, component B2 is a dispersant or dispersant mixture and contains ethoxylated alcohols and optionally a dihydric aliphatic alcohol and optionally an inorganic acid, and component B3 is water, and
• component C is a polymer containing perfluoroalkyl groups (RF groups), wherein 55 to 100% of all RF groups present contain 6 carbon atoms, and
• wherein the composition optionally further contains, as component D, a zirconium salt.
