Compositions comprising esters having perfluoroalkyl groups and oligo- or polyurethanes which may similarly contain perfluoroalkyl groups are useful for oil and water repellent processing of sheet-like textile materials. Such compositions may further comprise acrylic polymers and extenders containing perfluoroalkyl groups. In particular, the use of nonionic aqueous dispersions of such compositions results in little effect reduction and excellent LAD effects even if the fabric is damaged after mechanical wear. |
