Fibre development

The working scope of fibre development focuses on cellulose and its derivatives, proteins, polyacrylonitrile, polyvinyl alcohol and aramides. Activities encompass:

  • The preparation of polymer solutions
  • The development of fibres for production in wet or dry spinning processes
  • The development of spun-bonded fabric from solutions or low-melting polymers
  • The development of functionalised fibres and fibre non-wovens
  • Technology development for the production of man-made fibres

 

Sections:

 

  • Production and characterisation of polymer solutions
  • Textile fibres from polymer solutions
  • Spun non-wovens from solutions or low-melting polymers
  • Milling of inorganic and organic particles
  • Functionalization of fibres during fibre forming process
  • Functionalised cellulose fibres
  • Basic engineering for fibre production
