  • WATER- AND OIL-REPELLENT TREATMENT OF TEXTILE
    Publication number: 20100143641
    Abstract: Excellent water- and oil-repellency and soil releasability can be obtained by a method of preparing a treated textile, having steps of: (1) preparing a treatment liquid containing a water- and oil-repellent agent and a stain blocking 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 at least one fluorine-containing compound selected from the group consisting of a fluorine-containing polymer and a fluorine-containing low molecular weight compound, and the water- and oil-repellent agent or the treatment liquid contains a cationic emulsifying agent.
