Abstract

A method for impregnating organic fibers which comprises applying a composition containing (1) an organopolysiloxane having silicon-bonded condensable groups and containing diorganosiloxane units in which the two SiC-bonded organic radicals are monovalent hydrocarbon radicals and also contains two monovalent SiC-bonded radicals having a basic nitrogen group; (2) an organopolysiloxane having at least 3 Si-bonded hydrogen atoms per molecule; and (3) a catalyst which promotes the condensation of the silicon-bonded condensable groups, in which the SiC-bonded radicals having a basic nitrogen group are present in the organopolysiloxane (1) as monoorganosiloxane units and as diorganosiloxane units.
