Regenerated bacterial cellulose fibers prepared by the NMMO·H2O process

摘要: Abstract In this work, bacterial cellulose (BC) was dissolved in N-methylmorpholine-N-oxide monohydrate (NMMO·H 2 O), and regenerated BC fibers were prepared. Structure properties of the characterized by different techniques such as scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), thermogravimetric analysis (TGA), single filament electric tenacity tester. Results revealed that whole showed a circular shape with fairly regular size along fiber axis. There no significant difference between structure native fibers. The had II crystalline structure, lower degree crystallinity, smaller crystallite sizes, better thermal stability than BC. Tensile strength 0.5–1.5 cN/dtex, their extension at break 3–8%.
