- •
A modified three-step process for upgrading paper-grade pulp to dissolving pulp was proposed.
- •
Mechanical refining served to facilitate the hemicelluloses removal in the CCE by changing the fiber morphologies.
- •
The subsequent CCE can be carried out at a low sodium hydroxide concentration.
- •
A final enzymatic treatment increased the reactivity and control the viscosity of the product.
