摘要:
A fabric possessing both cleanability and fluid resistant properties is provided which can, if desired, be transfer printed. The fabric includes a textile substrate treated with a fluorochemical stain resist agent. The treated textile substrate is covered substantially on the back with a layer of extrusion coated thermoplastic polymer which is pressed at least partially into the fabric substrate. A process for forming the fluid shield fabric according to the present invention is also provided.

Fluorine-containing compositions for treating substrates to render them oil-, water- and soll-repellant, comprising a fluorine-containing acrylic copolymer and a fluorine-free poly(meth)acrylate.
摘要:
A method for imparting soil resistance to unscoured carpets, and a carpet treated in accordance with the method, are provided. In accordance with the method, a substrate comprising unscoured carpet fibers is treated with the ammonium salt of a polycarboxylic acid, such as an ammonium salt of a hydrolyzed styrene/maleic anhydride copolymer. The treated substrate is found to have enhanced water and oil repellency in both heat cured and room temperature drying conditions.

THIS SPECIFICATION DISCLOSES A NOVEL AROMATIC COMPOSITIONS CONTAINING TWO FLUOROALKYL SUBSTITUENTS EACH CONTAINING AT LEAST FOUR PERFLUORINATED CARBON ATOMS. THESE COMPOSITIONS ARE PREPARED BY REACTING A PHENYLENE DIAMINE, AMINOPHENOL OR DIHYDROXYBENZENE, SUBSTITUTED OR UNSUBSTITUTED, WITH A POLYFLUOROALKYL CARBOXYLIC ACID OR A POLYFLUOROALKYOXYALKYL CARBOXYLIC ACID, OR THE CORRESPONDING ACID HALIDE, ESTER OR ANHYDRIDE OF THESE ACIDS. THE NOVEL COMPOSITIONS OF THE INVENTION ARE USEFUL AS OIL REPELLENT COATINGS AND SIZES, PARTICULARLY FOR TEXTILES.
