Oil and water repellent compositions for the treatment of fiber containing substrates such as fabric and the like, substrates treated with these compositions and methods for the treatment of substrates are described. The compositions of the invention comprise (a) a polyalkoxylated polyurethane and (b) a fluorochemical acrylate polymer comprising the polymerized reaction product of a fluorinated acrylate or methacrylate monomer, at least one alkyl acrylate or methacrylate monomer and a polymerizable cationic emulsifier comprising a quaternary amine surfactant. Additionally, (c) a polyalkylene glycol fluorochemical acrylate copolymer and (d) a fluorochemical adipate ester can also be included within the compositions. The above components are blended together within the composition at a weight ratios of (a):(b), or (a)+(c):(b), or (a)+(c)+(d):(b) of from 19:1 to 1:19 and preferably about 1:1. The compositions may be applied to a variety of fiber containing substrates to achieve a broad range of oil and water repellent properties.

L'invention a pour objet des compositions hydrophobes et oléophobes pour le traitement de substrats à base de fibres et similaires, des substrats traités par ces compositions et des procédés pour traiter ces substrats. Les compositions selon la présente invention comprennent (a) un polyuréthane polyalcoxylaté et (b) un polymère d'acrylate fluorochimique comprenant le produit de réaction polymérisé d'un monomère de méthacrylate ou acrylate fluoré, au moins un monomère de méthacrylate ou d'acrylate d'alkyle et un émulsifiant cationique polymérisable comprenant un agent tensio-actif à amine quaternaire. En outre, (c) un copolymère d'acrylate fluorochimique de polyalkylène glycole et (d) un ester d'adipate fluorochimique peuvent également être inclus dans ces compositions. Les composants susmentionnés sont mélangés ensemble dans la composition, avec des rapports de poids de (a):(b), ou (a) + (c):(b), ou (a)+(c)+(d):(b) compris entre 19:1 et 1:19 et de préférence d'environ 1:1. Les compositions peuvent être appliquées à une variété de substrats à base de fibres pour obtenir une large gamme de propriétés hydrophobes et oléophobes.
