Green composites of regenerated cellulose short fibers/cellulose were prepared by dissolving cellulose in a green solvent of 7% NaOH/12% Urea aqueous solution that was pre cooled at -12°C. The effect of fiber loading on the tensile, optical, thermal degradation and cell viability was studied. The tensile properties of cellulose were improved by the regenerated cellulose fiber reinforcement. The interfacial bonding between the fibers and matrix was assessed using the fractographs and found it to be good.

ABSTRACT:The two layers of bilayered vegetable fabric from ridge gourd were analyzed by FTIR, chemical, X-ray, and thermogravimetric methods before and after alkali treatment. The morphology of the fabrics in the two layers, before and after alkali treatment, was also studied using SEM technique. The FTIR and chemical analyses indicated lowering of lignin and hemicellulose content by alkali treatment in the fabric of both layers. Further, the X-ray diffraction revealed increase in crystallinity of the fabric by alkali treatment. The thermal stability of the fabric was also found to increase by alkali treatment.

Green composites of waste silk short fibers/cellulose were prepared by dissolving cellulose in (7%NaOH/12%Urea) aqueous solution pre-cooled at −12°C. The effect of fiber loading on the tensile, optical, thermal degradation, and cell viability was studied. The interfacial bonding between the fibers and matrix was assessed using the fractograph.
