Excellent water repellency, Oil repellency, stain block property and yellowing-resistance are imparted to a textile by a method of preparing a treated textile has the steps of (1) preparing a treatment liquid containing a water- and oil-repellent agent and a stain blocking agent, (2) bringing a pH of the treatment liquid to at most 7, (3) applying the treatment liquid to the textile, (4) treating the textile with steam, and (5) washing the textile with water and dehydrating the textile. The treatment liquid contains a sulfated fatty acid compound.
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.
Treatment of textiles by a fluoropolymer-amino terminated polydiorganosiloxane composition is disclosed. The fluoropolymer-amino terminated polydiorganosiloxane compositions are prepared by combining a fluoropolymer and an amino terminated polydiorganosiloxane. The resulting compositions improve the hand or feel of the fabric without significantly diminishing oil repellency properties associated with fluoropolymers.
To improve the liquid barrier properties of a carpet, a repellency compound, such as a fluorochemical, is applied to the backstitch side or underside of the primary backing layer of a carpet.
