The Ioncell process utilizes a solvent called ionic liquid to dissolve cellulose. In the dissolved state, cellulose can be transformed into beautiful, strong fibers using the dry-jet wet spinning technology. The only chemicals applied are the non-toxic ionic liquid and water. They are both re-circulated in the process in a closed loop.
Ioncell fibers feel soft and are strong even when wet. The fiber properties of Ioncell are equal or better than viscose and Tencel® fibers. Because of their high tenacity, Ioncell fibers are optimal in technical applications such as composites.
Ioncell fiber properties
- Moisture absorbing
- Bright lustre
- Can be dyed like cotton and viscose
