Abstract
Fluorochemical urethane compositions comprising one or more fluorochemical urethane compounds, and one or more auxiliary compounds for treatment of a fibrous substrate are described. The fluorochemical compositions are capable of improving one or more of the oil- and/or water repellency, stain- and/or soil repellency and stain and/or soil release properties, with improved durability, of the fibrous substrate treated with the fluorochemical composition.
