Determination of Kamlet-Taft parameters to understand solvent-solute interactions.

Main Results:

The optimized 1:3 M TMAH·5H2O/Urea DES dissolved up to 7.5 wt% of high DP cellulose (526) at room temperature.
Both the pure DES and cellulose/DES mixtures exhibited low viscosity, suitable for fiber spinning.
Cellulose structure transformed from type I to type II, with reduced crystallinity and DP.
The DES demonstrated high hydrogen bond basicity, facilitating effective cellulose solvation.

Conclusions:

The TMAH·5H2O/Urea DES offers an efficient, low-viscosity system for cellulose dissolution at room temperature.
This solvent system presents advantages in synthesis simplicity and cellulose solubility.
It holds significant potential for advancing cellulose processing and applications in fiber manufacturing.
