Aqueous solutions or dispersions of organooligosiloxanes or organopolysiloxanes that include one or more nitrogen-containing side chains and in which a radical containing a polyoxyalkylene unit is bonded to the second Si atom of the chain are suitable for treating fiber materials. A pleasantly soft handle is hereby imparted to the fiber materials, in particular textiles. The novel siloxanes can be obtained by reacting dialkoxysilanes containing substituents having amino groups with cyclic trisiloxanes or tetrasiloxanes, followed by reaction with silanes that contain substituents having polyoxyalkylene units.
