DESCRIPTION:

BRIEF SUMMARY
This invention relates to oil and water repellent compositions for the treatment of fabrics and other fiber containing substrates at ambient conditions, to the treated substrates and to methods of treating those substrates.


BACKGROUND OF THE INVENTION

Substrates such as woven fabrics, carpeting, upholstery and the like become soiled and stained when used, requiring frequent and repeated cleaning. Various chemical compositions have been proposed for the protection of such substrates against water and oil based soils and/or stains, and the patent literature describes many such compositions. U.S. Pat. No. 5,350,795 to Smith et al., for example, includes a partial listing and discussion of the patent literature relating to fluorochemical compositions for the treatment of textiles and the like. As the literature indicates, fluorochemical compounds have been used successfully in the treatment of various substrates to render them more resistant to staining and, therefore, easier to clean.
Even though fluorochemicals have found fairly widespread use, fluorochemicals have generally required the inclusion of significant amounts of organic solvents which may be undesirable. The use of water based fluorochemical compositions (e.g., those which do not include significant organic solvents), while more acceptable, has been less than satisfactory because such aqueous compositions have generally required the performance of additional steps in the application of the composition to a substrate, such as the application of heat to the treated substrate. In light of the foregoing, it is desirable to provide oil and water repellent fluorochemical compositions which do not require a significant amount of organic solvent and which can be applied to a substrate and dried at ambient conditions to impart oil and water repellency.
In the evaluation of the oil and water repellent properties of treated substrates, certain known tests are employed to measure the degree to which a substrate effectively repels water and oil under different conditions. For any given composition, identical tests are performed on a number of different substrates (e.g., different fabric types) to fully assess the degree to which the composition is effective in protecting specific materials. As a result of such assessments, it is known that while some fluorochemical compositions will provide favorable or at least acceptable test results according to some of the aforementioned tests, the art has generally failed to provide a composition which is substantially free of organic solvents and which provides an improved range of oil and water repellent properties. Therefore, it is desirable to provide a composition suitable for the treatment of fiber-containing substrates which can be formulated and applied without significant mounts of organic solvents to provide a range of improved oil and water repellent properties at ambient conditions (e.g., the composition can be applied at room temperature without additional thermal treatment).


SUMMARY OF THE INVENTION

The present invention provides fluorochemical compositions suitable for application on a variety of fiber-containing substrates such as fabrics and textile fibers comprising cotton, nylon, polyester, polyolefin, acrylic, acetate, leather or blends thereof and materials such as apparel, upholstery and carpet to impart a broad range of oil and water repellent properties. The compositions of the invention are water based formulations which may be applied to substrates and dried without thermal treatment, i.e., at ambient conditions. Applicants have found that a class of fluorochemical acrylate polymers having a polymerizable cationic emulsifier incorporated with the polymer can be blended with polyurethane containing blends to provide a class of fabric protective compositions which exhibit improved oil and water repellency.
In one aspect, the invention provides a composition for treating fiber-containing substrates to impart improved oil and water repellency thereto, the composition comprising: said polyalkoxy
