摘要: Abstract Bacterial cellulose (BC) was dissolved in zinc chloride aqueous solution (ZnCl 2 ·3H O) with a maximal concentration of 5.5 wt%, and regenerated bacteria (RBC) nascent fibers were spun wet-spinning process. The behavior the BC/ZnCl O investigated, together structure properties RBC fibers. Results revealed that showed typical shear thinning behavior. Though there no chemical reaction occurred during dissolution spinning process, crystal forms transformed from I to II. Compared original BC fibers, had lower degree crystallinity thermal stability, round brilliants along fiber axis surface cracks fibrillation, which caused tensile strength 0.66–0.83cN/dtex, extension at break 1.95–3.66%.
