Ioncell-F technology developed at Aalto University in collaboration with the University of Helsinki converts wood into textiles without any harmful chemicals. It is an environmentally friendly alternative to the water-intensive cotton production. In addition, the process may revolutionize the recycling of textile waste, as waste cotton can get a new life as high-quality luxury fibers.

Ioncell-F technology turns used textiles, pulp or even old newspapers into new textile fibers sustainably and without harmful chemicals. The process converts cellulose into fibers which in turn can be made into long-lasting fabrics.

Ioncell-F was developed by the Biorefineries research group lead by Prof. Herbert Sixta.


The research group of Prof. Herbert Sixta focuses on the fractionation of lignocellulose and valorization of its constituents.
