Abstract

Chemical cellulose from an ascidian tunic is isolated by extraction, digestion and bleaching steps. The content of $\alpha$-cellulose was above 98 wt%, and it's DPw was about 918. A new regenerated cellulose fiber from the chemical cellulose obtained in this study was made using NMMO/water(87/13 wt%) as a solvent by dry jet-wet spinning. The effects of spinning speed and cellulose content of spinning dope on the properties were investigated.
