dc.description.abstractIN THE FINAL PROCESS OF THE BLEACHED KRAFT PULP THERE ARE SOME CELLULOSE FIBERS THAT ARE SEPARATED FROM THE MAIN FIBERS STREAM; THESE FIBERS ARE REJECTED AND CONSIDERED AS A LOW QUALITY FIBERS, THESE FIBERS ARE KNOWN AS REJECTED FIBER (RF). IN THE PRESENT WORK THE POTENTIAL USE OF THESE FIBERS FOR CELLULOSE NANOCRYSTALS (CNCS) SYNTHESIS WAS STUDIED. THE PHYSICAL AND CHEMICAL PROPERTIES OF SYNTHESIZED CNCS WERE CHARACTERIZED THROUGH DIFFERENT TECHNIQUES SUCH AS ATOMIC FORCE MICROSCOPY (AFM), SCANNING ELECTRON MICROSCOPY (SEM), X-RAY DIFFRACTION (XRD), FOURIER-TRANSFORM INFRARED SPECTROSCOPY (FTIR), AND THERMOGRAVIMETRIC ANALYSIS (TGA). RESULTS DEMONSTRATE THE FEASIBILITY OF CNCS SYNTHESIS WITH A YIELD OF 28.1% AND 36.9%, AND CRYSTALLINITY OF 73.5% AND 82.7%. FINALLY, THE MORPHOLOGY AND SYNTHESIS CONDITIONS SUGGEST THAT THIS INDUSTRIAL REJECT FIBER (RF) COULD BE USED AS A SOURCE FOR THE CNCS PRODUCTION, THUS ADDING VALUE TO THE KRAFT PROCESS AND OPENING NEW POSSIBILITIES FOR INNOVATION IN THE PULP INDUSTRY.
