Abstract:

The dissolving of cellulose in suitable solvents to prepare fibre-forming and film-forming solutions has been a very attractive field of research for more than a hundred years. In this paper we present the rheological properties of alkali solutions of enzyme-treated cellulose (BiocelsolTM) and the blend of Biocelsol-viscose solutions. The effect of solution composition, storage temperature and time on the viscosity and deviation from the Newtonian flow were investigated. The reproducibility of the basic rheological parameters of Biocelsol alkali solutions was also investigated. The effect of the rheological properties of Biocelsol/viscose blend solutions on the tenacity of the regenerated cellulose films is discussed, as well.
