Abstract: 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.

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.

Abstract: 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: 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.

Abstract: This invention relates to chemical compositions comprising one or more urethane oligomers of at least two repeating units selected from the group consisting of fluorine-containing urethane oligomers and long-chain hydrocarbon-containing urethane oligomers. These urethane oligomers comprise the reaction product of (a) one or, more polyfunctional isocyanate compounds; (b) one or more polyols; (c) one or more monoalcohols selected from the group consisting of fluorochemical monoalcohols, optionally substituted long-chain hydrocarbon monoalcohols, and mixtures thereof; (d) one or more silanes; and optionally (e) one or more water-solubilizing compounds comprising one or more water-solubilizing groups and at least one isocyanate-reactive hydrogen containing group. The chemical compositions of the present invention can be applied as coatings and these coatings can impart stain-release characteristics and resist being worn-off due to wear and abrasion.

Abstract: Fluorochemical polymers for use in providing stain-release properties to a substrate material are disclosed. The present invention provides for polymeric fluorochemical polymers that include perfluoroaliphatic, hydrophilic, cationogenic, and either N-hydroxyalkylacrylamide and/or diacrylate monomers.

Abstract: A liquid or dry, flowable cleaning composition for carpeting is provided which comprises: (1) a cleaning fluid selected from water containing sufficient surfactant to lower the surface tension to below 40 dynes per centimeter, an organic liquid, or mixtures of water, surfactant and organic liquid; and (2) a sulfonated, colorless dye site blocker provided in a sufficient amount to prevent or minimize deterioration of stain resistance properties in fifth generation nylon carpets. In the case of a dry-type composition sufficient particulate material is added to provide a dry, flowable product.
