报告一摘要

1.Introduction

　　A brief review on regenerated cellulose process, including traditional viscose process and new developed Lyocell process.

2.Filaments from eucalyptus pulp

　　Filaments of different sizes were spun from a fully bleached eucalyptus kraft pulp using Lyocell-NMMO process. Process parameters, including dope viscosity, spinning head temperature and pressure, spinning gap, were discussed.

3.Cellulose degradation in Lyocell process

　　Cellulose molecular weight distributions of initial pulp fiber and the regenerated cellulose from aged dopes were determined to assess the degradation in cellulose during and after dissolution in the solvent system.

4.Solvent degradation in Lyocell process

　　Degradation of N-methylmorpholine oxide in Lyocell process was evaluated using GC/MS. The well recognized degradation products were confirmed; never-reported degradation products were detected; degradation pathways were discussed.
