Sustainable textiles

Textiles and clothing play a central role in our everyday lives. The growing negative environmental impact of textile production prompts researchers, manufacturers and decision makers worldwide to take action.

Our research team continues the development of the Ioncell® process which was established by Professor emeritus Herbert Sixta in collaboration with the University of Helsinki. The focus is on textile recycling and sustainable dyeing processes. Further, nonwoven and technical applications such as fiber reinforced composites and new routes for the functionalization of biobased fibers are explored.
