REPELLENT FLUOROCHEMICAL COMPOSITIONS |
摘要 |
<p>This invention provides compositions for treating fibrous substrates to render those substrates durably repellent to water and oil and durably resistant to dry soil comprising a 1) fluorochemical urethane formed by reacting a tri- or higher order isocyanate with a fluorochemical monofunctional compound and optionally a non-fluorinated aliphatic monofunctional compound; and 2) a fluorochemical polymeric surfactant. The present invention also provides a method of treating fibrous substrates to render those substrates durably repellent to water and oil and durably resistant to dry soil comprising application of the aforementioned composition to a fibrous substrate with optionally one or more stainblocker compounds such as acrylic and methacrylic acid polymers and copolymers, sulfonated phenol-formaldehyde resins, and styrene-maleic anhydride polymers and copolymers, said application of the composition taking place either coincident with or following application of the hydrophilic anti-staining compound or compounds to the substrate. Fibrous substrates treated according to this method and fibrous substrates treated with the aforementioned compositions are also disclosed.</p> |
