Preparation and Characterization of Cellulose Nanofibers from Jute Using Blender Combined with Chemical Pretreatments

Jute nanofibers were prepared by treating jute fibers with chemical pretreatments then applying blender finishing. Scanning electron microscopy (SEM) observations revealed that the structure of the jute fibers changed significantly after 20 times blender. Field emission scanning electron microscopy(FE-SEM) images showed that the jute nanofibers exhibited web structure, with diameter in the range of 80-250 nm, and length of more than a few micrometers. Fourier transform infrared (FTIR) results indicated that hemicellulose and lignin were removed extensively after chemical treatments.The results of X-ray analysis (XRD) indicated that the degree of crystallinity increased compared with the raw material, with the crystallinity approximately 66.27% for jute nano fibers.
