AQUEOUS OIL AND WATER REPELLENT COMPOSITIONS

摘要

Fluorochemical compositions for treating textile fibers and fabrics to impart oil and water repellency without thermal treatment are provided. The compositions comprise an aqueous, substantially organic solvent free, solution or dispersion of (a) a fluorochemical acrylate copolymer comprised of a fluorinated acrylate monomer, polyalkylene glycol acrylate or methacrylate, and polyalkylene glycol diacrylate or dimethacrylate; and (b) a polyalkoxylated polyurethane having pendant perfluoroalkyl groups comprised of an aliphatic or aromatic triisocyanate or polyisocyanate, a fluorinated alcohol, amine, or mercaptan, and a poly(oxyalkylene) diol or dithiol.
