Claim 1

Textile drying process comprising continuously contacting a moving textile web, which is wet with a first fluorocarbon liquid having a textile agent dispersed therein, said agent being a dye, a bacteriostatic agent, an ultraviolet light screening agent, a fluorescent brightening agent, a fire retardant agent, an antistatic agent, a pigment, a water repellent, a fungicide, a soil release agent or a permanent-press agent, with the superheated vapors of a second fluorocarbon liquid, the superheated vapors being at a temperature such that no substantial amount of second fluorocarbon liquid condenses on the web, to evaporate substantially all of the first fluorocarbon liquid from the web in no more than seven seconds without causing substantial migration of the textile agent on the web, said first and second fluorocarbon liquids being the same or different and selected from fluoro and chlorofluoro substituted aliphatic and cycloaliphatic hydrocarbons, ethers and tert.-amines wherein the ratio of hydrogen atoms to halogen atoms is 0-0.2, the first fluorocarbon liquid having a boiling point of 20°-110° C. and the second fluorocarbon liquid having a boiling point of 20°-220° C.
