Abstract:
A process for dry cleaning fabric, said process comprising the step of cleaning fabric by applying an effective amount of a cleaning composition for dry cleaning which comprises 1 to 90% by weight of a surfactant containing fluorine and 10 to 99% by weight of a fluorohydrocarbon solvent and/or an auxiliary solubilizing agent, wherein the surfactant containing fluorine is a salt of a phosphoric acid ester of a polyoxyalkylenealkylsulfonamide ether containing fluorine which is represented by general formula (1): ##STR17## wherein R.sup.1 represents a perfluoroalkyl group having 3 to 12 carbon atoms, R.sup.2 represents an alkyl group having 1 to 5 carbon atoms, R.sup.3 represents an alkylene group having 2 to 4 carbon atoms, q represents a number of 0 to 10, and r represents a number of 1 or 2,wherein said step of cleaning with a composition which includes the fluorohydrocarbon solvent includes the further step of providing an alkoxyperfluoroalkane represented by general formula (5):C.sub.n F.sub.2n+1 OC.sub.m H.sub.2m+1 ( 5)wherein n represents a number of 3 or 4, and m represents a number of 1 to 3.
