Abstract
Abstract An organopolysiloxane composition comprising (A) at least one diorganopolysiloxane containing Si-bonded terminal hydroxyl groups, (B) at least one organosilane of the general formula RSiR' n X 3-n , in which R represents a monovalent group containing carbon, hydrogen, aminonitrogen and possibly oxygen, which contains at least 2 amino groups that are bonded to silicon via silicon-carbon bond, R' represents an alkyl or aryl group, X represents the same or different alkyl or substituted alkyl groups having from 1 to 14 carbon atoms which are bonded to silicon via oxygen, n is 0 or 1 and/or partial hydrolysates thereof, (C) at least one organosilane other than (B), having at least three oxime groups and, if desired, (D) at least one condensation catalyst and an organic solvent, and a process for treating organic fibers therewith.
