Hydrophobic fibers are prepared by treating fibers with a composition containing an organopolysiloxane having Si-bonded hydrogen atoms as essentially its only reactive group, and a platinum catalyst which is inhibited by a compound which is volatile under the conditions at which the organopolysiloxane containing Si-bonded hydrogen atoms is deposited on the fiber.

Method for imparting hydrophobic properties to fibers

This invention relates to a process for preparing tetrafluoroethyloxyalkyl silanes by the addition of silanes containing Si-bonded hydrogen to tetrafluoroethyl-alkenylether in a tubular reactor in which the reaction mixture containing an excess of silanes is recycled at a rate of at least 10 meters per minute.
