The present invention relates to a fluorochemical composition for rendering fibrous substrates oil repellent, water repellent and/or stain or soil repellent. Additionally, the invention also relates to fluorochemical compositions for providing stain release or soil release properties to fibrous substrates. In particular, the present invention relates to fluorochemical compositions that contain a fluorinated polyether compound that can be obtained by reacting an isocyanate component with a particular isocyanate reactive fluorinated polyether compound and a stain release compound. The invention further relates to a method of treating the fibrous substrate with the fluorochemical composition.

Fluorochemical composition for treatment of a fibrous substrate

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.
