Abstract
Fiber-treating compositions are described which durably provide water repellency and oil repellency for the treated fibers. These compositions comprise a cyclic siloxane bearing fluorinated hydrocarbon radicals and silicon-hydride atoms, and a dehydrogenation catalyst. Curing of the compositions occurs by a dehydrogenation condensation reaction between the silicon-hydride atoms and/or between the silicon-hydride atoms and the hydroxyl radicals of an optionally added hydroxyl-endblocked organopolysiloxane.
