Aqueous dispersions comprising as component A) a compound containing two or more blocked isocyanate groups in the molecule and as component B) a compound obtainable by reacting a diepoxy compound with a diamine or polyamine and subsequently reacting the resulting reaction product with an acid and possibly as component C) a dispersant are suited together with fluorine containing oligomers or polymers for the oil-, water- and soil-repellent finishing of fiber materials.

Aqueous dispersions for textile finishing

Products which are produced by reaction of diisocyanates with di- or polyhydric alcohols and/or with one or more mono- and/or diethers of such alcohols and subsequent reaction with organic amines containing two or more alcoholic hydroxyl groups and subsequent blocking of free isocyanate groups are suitable for the finishing of fiber materials, in particular in the form of aqueous dispersions as extenders for use in combination with polymers containing perfluoroalkyl groups for the oil-, water- and soil-repellent finishing of fiber materials.

A process is described for the preparation of modified polysiloxanes by reaction of polyvinylsiloxanes with compounds of the formula ##STR1## in which R is H, CH.sub.3 or C.sub.2 H.sub.5, in which at least one radical R is H, and R.sub.f is a perfluoroalkyl radical having 8 to 16 C atoms, in about equivalent amounts, relative to the vinyl groups, at elevated temperature. In addition, the polysiloxanes prepared in this manner are protected. Equally, the use of these polysiloxanes for the oil- and water-repellent treatment of fiber materials is claimed. This treatment makes it possible to achieve very good wash- and cleaning-resistant oil- and water-repellency, using small amounts of fluorine.

The present invention relates to a process for obtaining wash- and cleaning-resistant textile finishes by impregnating with customary reactive perfluoroalkyl-containing (co)polymers and/or precondensates in aqueous dispersion and concluding heating, wherein the dispersions have NCO-containing compounds which have a molecular weight of at least 450 and/or contain a diphenylmethane-based polyisocyanate mixture in blocked form. The process according to the invention has made it possible to equip textiles with water-repellant and oil-repellant finishes which are very highly wash- and cleaning-resistant.

Process for the production of perfluoroalkyl residue containing

The invention provides a process for the manufacture of addition products from nitrogen containing compounds which contain at least one ethylenically unsaturated radical and organopolysiloxanes which contain hydrogen atoms bonded to silicon, and a process for treating fibrous materials with the resultant addition product composition. The process comprises adding to the organopolysiloxanes allylmelamines, allylguanamines, monoallyl- or diallylureas, monoallyl- or diallylthioureas or cyclic urea derivatives which contain at least one ethylenically unsaturated radical. The addition is carried out in the presence of methylolated aminoplast formers which can also be etherified with lower alcohols, or in the presence of the cited unsaturated compounds in their methylolated form. The unsaturated compounds can also be used direct in methylolated and etherified form. The resultant addition products are used in an aqueous emulsion or an organic solvent for the treatment of fibrous materials. The treated materials are provided with a good wash-resistent water repellent finish.
