Regenerated cellulose fibers from rice straws with a diameter of 10 to 25 m
um and initial modulus of 11 to 13 GPa were prepared by wet spinning in ric
e straw/N-methylmorpholine-N-oxide (MMNO) solution. X-ray diffraction analy
sis indicates that the rice straw regenerated fibers are classified as cell
ulose (II). This observation indicates a potential utility of rice straw as
an alternative to wood pulp as a cellulose-based fiber material. (C) 2001
