Described are 8 aqueous compositions useful for treating textile materials to impart oil- and/or water-repellent properties thereto. The compositions contain inter alia polymers containing perfluoroalkyl groups (Rgroups), wherein 55 to 100% of the Rgroups contain 6 carbon atoms.

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

Copolymers which are composed of at least 4 monomers, including (meth)acrylate compounds containing perfluoroalkyl groups, are suitable for the treatment of fiber materials. The copolymers are usually used here in the form of aqueous dispersions. The fiber materials are in particular fabrics, for example made of polyolefin. Treatment with the copolymers imparts to them oil- and water-repellent properties and also repellent properties toward low molecular weight alcohols.

Copolymers containing perfluoroalkyl groups and aqueous dispersions thereof

The use is described of aqueous dispersions in combination with fluoropolymers for oil- and water-repellent finishing of fiber materials. These dispersions have a long shelf life and contain a composition which is preparable by reaction of polyfunctional isocyanates with a deficiency of comparatively long-chain monohydric alcohols, subsequent reaction with a deficiency of a ketone oxime and final reaction with polyhydric alcohols or amino alcohols.

Extender for treatment of fiber materials

Fiber materials in the form of fabrics receive, as a result of treatment with compositions according to the invention, a pleasant soft hand and excellent oil-and water-repelling properties with good permanence. The compositions can be obtained by a) preparing a solution of a polysiloxane and an extender with blocked isocyanate groups in an organic solvent, b) dispersing this solution in water, c) removing the organic solvent and d) combining the aqueous dispersion obtained with a second aqueous dispersion which comprises a polymer with perfluoroalkyl groups. One variant of this preparation process consists in cousing a polymer with perfluoroalkyl groups as early as in step a). In this case, step d) can be omitted.

Compositions of polysiloxanes, fluoropolymers extenders

Gaseous or volatile substances which are either themselves odor-active or components of odor-active mixtures of substances are applied to fabrics. The amount of these substances adsorbed by the textiles is then determined. It is then determined what amount of these substances is desorbed again by the textiles upon storage. Comparison of the results which are obtained on textiles which had been finished beforehand with textile auxiliaries with the results of non-finished textiles enables statements to be made regarding odor-inhibiting properties of textile auxiliaries.
