Abstract
Polyorganosiloxane mixtures are obtainable by reacting linear polysiloxanes containing Si—H-bonds with linear dihydroxypolysiloxanes and amino-functional silanes. The reaction is carried out in such a way that the resultant product mixture still contains Si—H— bonds and leads to crosslinked structures. The polysiloxane mixtures obtained are useful for hydrophobicizing fiber materials, especially nonwovens.
