Abstract

Abstract Translated from German Organische Fasern werden mit Organopolysiloxan (1), das zusätzlich zu Diorganosiloxaneinheiten, worin die beiden SiC-­gebundenen, organischen Reste einwertige Kohlenwasserstoff­reste sind, mindestens zwei einwertige SiC-gebundene Reste mit basischen Stickstoff enthält, imprägniert, wobei mindes­tens ein Teil der SiC-gebundenen Reste mit basischem Stick­stoff aus SiC-gebundenen N-Cyclohexylaminoalkyl-Resten besteht. Die SiC-gebundenen N-Cyclohexylaminoalkyl-Reste liegen in Monoorganosiloxan- und/oder Diorgansiloxan- und/oder Triorganosiloxaneinheiten vor. Bevorzugt als SiC-­gebundener N-Cyclohexylaminoalkyl-Rest ist der SiC-gebundene N-Cyclohexyl-3-aminopropyl-Rest. Das Organopolysiloxan (1) enthält gegebenenfalls direkt an Silicium gebundene, kondensationsfähige Gruppen. Organopoly­siloxan (1), das direkt an Silicium gebundene, kondensations­fähige Gruppen enthält, kann zusammen mit Organopolysiloxan (2a), das mindestens 3 Si-gebundene Wasserstoffatome je Mole­kül aufweist, oder zusammen mit Trialkoxy- oder Tetraalkoxy­silanen (2b) und gegebenenfalls zusammen mit Katalysator (3) für die Kondensation von direkt an Silicium gebundene, kondensationsfähige Gruppen eingesetzt werden. Organic fibers are impregnated with organopolysiloxane (1) which, in addition to diorganosiloxane units in which the two SiC-bonded organic radicals are monovalent hydrocarbon radicals, contains at least two monovalent SiC-bound radicals with basic nitrogen, at least some of the SiC-bonded radicals with basic nitrogen consists of SiC-bonded N-cyclohexylaminoalkyl residues. The SiC-bonded N-cyclohexylaminoalkyl residues are present in monoorganosiloxane and / or diorganosiloxane and / or triorganosiloxane units. The SiC-bound N-cyclohexylaminoalkyl radical is preferred as the SiC-bound N-cyclohexyl-3-aminopropyl radical. The organopolysiloxane (1) may contain condensable groups bonded directly to silicon. Organopolysiloxane (1), which contains condensable groups bonded directly to silicon, can be used together with organopolysiloxane (2a), which has at least 3 Si-bonded hydrogen atoms per molecule, or together with trialkoxy- or tetraalkoxysilanes (2b) and optionally together with catalyst ( 3) can be used for the condensation of groups which are bonded directly to silicon and are capable of condensation.
