Paper Title:
The Research on Dissolving Properties of Biodegradable Cellulose Pulp
  Abstract

For making Eco-Friendly cellulose sponge, cellulose pulp dissolving properties were researched in this paper. NaOH and NaOH/Urea solutions were both used, various factors (temperature, concentration and time) on viscosity of the pulp were studied. At first, ten different kinds of cellulose pulps were dissolved at low temperature in a certain range of concentration of NaOH solvent and the pulp with best soluble property was chosen. On the above basis, effects of the temperature of alkaline solvent and concentration on the viscosity of the selected pulp was fatherly experimented and analyzed. The result was got that at concentration of 8% of NaOH solution and at temperature of -5°C, the cellulose pulp has the best solubility. In the meantime, the solution has the biggest viscosity. On the other hand, NaOH/Urea solvent was tested for cellulose solubility. After experiment, the tests showed that when NaOH/Urea blending ratio is 8:12, the selected pulp solves completely and the solution was clear. Thus NaOH/Urea solvent has better solubility than that of NaOH solution for solving the cellulose pulp.
