Title: Erich Rössler: Innovator in Polysiloxane Technology

Introduction

Erich Rössler is a notable inventor based in Stadtbergen, Germany. He has made significant contributions to the field of polysiloxane technology, holding three patents that showcase his innovative approach to treating fiber materials.

Latest Patents

Rösslers' latest patents include the development of polyorganosiloxane mixtures for treating fiber materials. These mixtures are created by reacting linear polysiloxanes containing Si–H-bonds with linear dihydroxypolysiloxanes and amino-functional silanes. The process ensures that the resultant product mixture retains Si–H-bonds, leading to crosslinked structures. The polysiloxane mixtures obtained are particularly useful for hydrophobicizing fiber materials, especially nonwovens. Another significant patent involves the use of selected polydiorganosiloxanes in fabric softener compositions. This invention relates to fabric softeners that include a quaternary ammonium compound derived from tallow fatty acid and a nitrogen-free polydiorganosiloxane with terminal silicon-bonded hydroxyl groups. These compositions not only impart a soft handle to treated textiles but are also readily biodegradable, enhancing the rewettability of the fiber materials.
