摘要：
The invention provides a method of treating of a substrate by contacting the substrate with a fluorochemical composition that comprises a condensation product of a di- or tri-isocyanate and at least one polyether, the polyether being obtained as the reaction product of a fluorochemical substituted epoxide. Substrates treated in accordance with the invention have good stain release properties, particularly to oil stains or tea stains, so stains can be more easily removed from the treated substrate in a laundering procedure.
