The oil- and water-resistant finish for fiber fabrics is composed of an ester with perfluoroalkyl groups and an oligo- or polyurethane which can also contain perfluoroalkyl groups. The composition can also contain additional acryl polymers, with perfluoroalkyl groups and an extending filler. The ester and oligourethane or polyurethane are converted with a dialcohol
