Beschreibung
Zusammenfassung:	A fluorochemical composition for rendering a fibrous substrate oil and/or water repellent which comprises a solution or dispersion of a fluoropolymer having a partially or fully fluorinated backbone and comprising one or more repeating units corresponding to the general formula (I) wherein Rf represents a perfluorinated organic group having a chain length of at least 2 atoms and having at least one carbon atom and optional auxiliary components. Cette invention concerne une composition fluorée permettant à un substrat fibreux d'exercer une action répulsive sur l'huile et/ou l'eau. Cette composition comprend une solution ou une dispersion de fluoropolymère comportant un squelette partiellement ou entièrement fluoré et comprenant une ou plusieurs unités récurrentes correspondant à la formule générale (I). Dans cette formule, Rf représente un groupe organique perfluoré ayant une longueur de chaîne d'au moins 2 atomes et comptant au moins un atome de carbone et d'éventuels composants auxiliaires.
