Biobased composites were successfully prepared using raw materials derived from biomass waste, i.e., an epoxy resin obtained cardanol and nanocellulose unbleached hemp fibers. The by solvent exchange impregnation of the cellulosic mat with resin, followed photocuring. Quantitative conversion was obtained, despite high amount fibers (30 wt%) their absorbance in UV region light spectrum. X-ray di...
Delignified cellulosic material has shown a significant promotional effect on the alcoholic fermentation as yeast immobilization support. However, its potential for further biotechnological development is unexploited. This study reports the characterization of this tubular/porous cellulosic material, which was done by SEM, porosimetry and X-ray powder diffractometry. The results showed that the...
Among the various advanced materials, flame-retardant cellulosic textiles are important as they directly relate to human health and hazards. The use of environmentally friendly coatings is currently one major concerns in textile coating industry. In this work, acrylic acid was grafted onto surface cotton using plasma technology enhance attachment acrylate phosphate monomer. Surface analyses, su...
This study characterizes the acoustical behavior of natural fiber composites. Regenerated cellulose fibers (Lyocell), hemp fibers, and flax fibers were embedded in an epoxy-matrix. These unidirectional composites were tested for their logarithmic damping decrement, the resonance frequency, the ultrasound velocity, the dynamic and static modulus of elasticity, and bending strength and density. G...
Besides its growing impact on the Chemical fiber market, the amine Oxide process, employing a melt of N-methyl-morpholine-N-Oxide (NMMNO) as solvent for cellulose, is both a Stimulus to research in cellulose structure formation from Solution and a catalyst in getting People from fundamental and applied research together for joint effort [ 11. It is well known that cellulosic fibers of the ,,Lyo...
AbstractIn the present study , a novel method for the production of silk nano fibers are presented . In this way , a mechanical and easy technique is used instead of toxic and costly chemical methods . Also , the separation of silk nano fibers from the cocoon was carried out by mechanical homogenizer and probe ultrasonic homogenizer . After the preparation of silk nanofibers , the product was c...
