Natural Cellulose Fibers from Eulaliopsis Binata

Natural cellulose fibers extracted from Eulaliopsis Binata (EB) were systematically investigated in this paper. Fourier-transform infrared (FTIR), Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) were used to investigate the chemical composition, morphological structure and crystalline structure of the resulting fibers. Furthermore, some basic physical properties of the EB fiber, i.e., mechanical properties, water absorption, antimicrobial performance were also evaluated and discussed. It was found that the non-cellulose substances were su±ciently removed or reduced after the degumming process, but the cellulose I structure was not changed based on the XRD and FTIR results. Meanwhile, the EB fibers exhibited high breaking strength (3.5?6.9 cN/dtex) and remarkable moisture region (6.3?7.7%). It also exhibited moderate antimicrobial effects against Escherichia coli. All these results indicated that the BP fibers had properties resembling those of traditional natural cellulose fibers (e.g. cotton and flax); therefore, they could be viewed as a promising alternative source for natural cellulose bundle fibers.
