“…The residue from the degradation step at this onset temperature of degradation was 16, 15, 13, and 12 wt% for raw, alkali-treated, bleached, and acid-hydrolysed cellulose, respectively. The higher amount of residues in the raw Agave fibre is due to the presence of lignin as well as ash, which both have a slow degradation rate (Ashori et al 2006). On the other hand, the small amount of residues in the acid hydrolysed cellulose may be the results of the lignin removal during the acid hydrolysis.…”

Cellulose nanocrystals were extracted from Agave angustifolia fibres by alkali and bleaching treatments followed by acid hydrolysis. The chemical composition of the Agave fibres was determined at different stages of chemical treatment. The structural analysis was carried out by a Fourier Transform Infrared spectroscopy and X-ray diffraction. The morphology and thermal stability of the Agave fibres at different stages of chemical treatment were investigated by field emission scanning electron microscopy and thermogravimetric analysis, respectively. The results indicated that the hemicellulose and lignin were removed extensively from the extracted cellulose. The two peaks at 1735 cm -1 and 1247 cm -1 , which were attributed to the C=O stretching and C-O out of plane stretching vibration of the hemicellulose and lignin in raw Agave, completely disappeared in the spectra of chemically treated fibres. The X-ray diffraction data showed enrichment in the portion of crystalline cellulose from 59% to 82% in the raw and cellulose nanocrystals, respectively. Thermogravimetric analysis showed that the thermal stability improved significantly by various chemical stages. The size reduction of the Agave cellulose into nano-sized particles from 7 µm to 8 nm in diameter by acid hydrolysis was confirmed with transmission electron microscopy images.

“…The benefits of natural fibers that make them attractive include their relatively low cost, light weight, environmental friendliness, and competency in terms of strength per weight of material (John and Thomas 2008;Malkapuram et al 2009). In the 21 st century, the growing awareness of avoiding destruction of forests has raised the demand of using non-wood plant fiber instead of wood plant fiber (Ashori et al 2006). Examples of nonwood plant fibers include bagasse, bamboo, rattan, wheat, and kenaf, which have become attractive alternatives to natural fibers for use as reinforcement and/or fillers (Ashori et al 2006).…”

Of all the non-wood plant fibers, kenaf (Hibiscus cannabinus) has been widely used in research studies Majid et al 2010;Akil et al 2011;Saba et al 2015).…”

aThis study was conducted to evaluate the possibility of utilizing kenaf (KNF) in LLDPE/PVOH to develop a new thermoplastic composite. The effect of KNF loading on the processability and mechanical, thermal and water absorption properties of linear low-density polyethylene/poly (vinyl alcohol)/kenaf (LLDPE/PVOH/KNF) composites were investigated. Composites with different KNF loadings (0, 10, 20, 30, and 40 phr) were prepared using a Thermo Haake Polydrive internal mixer at a temperature of 150 °C and rotor speed of 50 rpm for 10 min. The results indicate that the stabilization torque, tensile modulus, water uptake, and thermal stability increased, while tensile strength and elongation at break decreased with increasing filler loading. The tensile fractured surfaces observed by scanning electron microscopy (SEM) supported the deterioration in tensile properties of the LLDPE/PVOH/KNF composites with increasing KNF loading.

“…Due to decreases in forests and increasing environmental awareness, seeking alternative non-wood raw metarials for papermaking has been the subject of scientifi c interest (Kaldor, 1992). Non-wood plant fi bers, such as bagasse, wheat and rice straws, bamboo and kenaf are being used in the manufacture of pulp and paper (Ashori et al, 2006). Search for new non-wood raw materials will lead to discover alternatives to wood-based raw materials.…”
