摘要：

High-quality cellulose multifilaments (see figure) are spun using a preliminary pilot apparatus, from the cellulose dope in an NaOH and urea aqueous solution precooled to -12 degrees C, by using a low-cost, simple, and environmentally friendly process. Small-angle X-ray scattering patterns indicate that the orientation of the multifilaments increase with a drawing process, leading to the improvement of their tensile strength.
