Abstract
A method of preparing a treated textile, having steps of: (1) preparing a treatment liquid comprising a water- and oil-repellent agent, (2) adjusting pH of the treatment liquid to at most 7, (3) applying the treatment liquid to a textile, (4) treating the textile with steam, and (5) washing the textile with water and dehydrating the textile, wherein the water- and oil-repellent agent contains (A) a fluorine-containing compound which is a fluorine-containing polymer, and (B) a urethane compound and/or (C) a silicon-containing compound, can give a textile which is excellent in water repellency, oil repellency and soil releasability, when the textile is treated with the treatment liquid by an Exhaust process.
