摘要:
The present invention provides an agent for treating textile having a combination of a modifying agent and a fixing agent, wherein the modifying agent is a fluorine-containing phosphoric acid derivative represented by the formula wherein R.sup.1 and R.sup.2 are, same or different, a hydrogen atom or R.sub.f --(CH).sub.2).sub.m -- (wherein R.sub.f is a saturated or unsaturated, linear or branched fluorine containing aliphatic group having 4 to 20 carbon atoms in which an oxygen atom, a nitrogen atom, a sulfonyl group and/or an aromatic ring may intervene between the carbon atoms; and m is 1 or 2) (R.sup.1 and R.sup.2 each is not simultaneously a hydrogen atom), A is an oxygen atom, a sulfur atom or a direct bond, and n is 1 or 2, and having a molecular weight of not larger than 2,000 or a salt thereof, and the fixing agent is a metal salt compound; and a method for treating a textile by using the above agent for treating a textile and, if necessary, a fluorine-containing water- and oil-repellent or a fluorine-containing stainproofing agent. The present invention can maintain the touch, feeling, color shade and softness originally possessed by the fibers even if the textile is treated. The present invention can maintain the above properties even if the textile is subjected to a long term use including the washing and rubbing, and can impart hot water repellency and durable water- and oil-repellency.
