Abstract:

Current research at ITV Denkendorf makes use of functionalisation with nanotechnology based materials, like nano fibres or nano particles in fibres or in fibre coatings and in fabric finishing.:

  • The centrifuge spinning process has been developed to produce nano fibres with diameters of some hundred nanometers with much higher productivity compared to the well established electrostatic spinning.
  • Fibre coatings and fabric finishing with integrated nano particles has been developed to produce nano scaled rough structures with reduced contact area and subsequently reduced adhesion to liquid and solid matter. Thus water droplets remove loosely attached dirt particles from the surfaces, called the self-cleaning effect.
  • A single-yarn coating line has been adapted for the permanent functionalization of yarns.
  • To achieve permanent antistatic effects, nanoparticles out of conductive materials are included into coatings. Surface resistance well below one Mega-Ohm has been achieved.
  • Hygienic and antimicrobial effects are based on the sol-gel process, adapted for textile processing. Integrated bioactive particles are responsible for a reduced microbial activity on textile surfaces for automotive applications.
  • Intensive efforts are done to evaluate the risk potential release of nano-dimensional matter out of mentioned materials during processing and use.
