Investigation of the spinnability of cellulose/alkaline ferric tartrate solutions

► Maximum ca. 12% cellulose was dissolved in FeTNa at −9 °C under shear force. ► Cellulose/FeTNa solutions show gel properties measured by dynamic rheometer. ► In reaction calorimetry, thermal activity of solutions occurred above 80 °C. ► Above 90 °C decomposition of cellulose/FeTNa complex changed the color of solution.
