“…Subsequently, fibres are separated from the matrix by calendering the leaf and then washed. A temperature of 120 • C and duration of 90 min appear to be the best conditions for the treatment as demonstrated in a previous study (Chaâbouni, 2005;El Oudiani, Chaâbouni, Msahli, & Sakli, 2009). …”

“…No significant differences in intensity of the absorption bands noted in the fibers taken from three (3) different locations of the internodes or the nodes. Absorbance at 897,1049,1161,1430,1734,2906,3411 per cm was associated with the characteristic absorption of lignocelluloses materials (El Oudiani et al, 2009;Yang et al, 2008). These absorbances are present in all the FTIR of the bamboo studied irrespective of the location of the fiber.…”

“…The absorption at 2899 per cm and 3412 per cm are attributed to the stretching vibration of OH groups and CH stretching, respectively, corresponding to the aliphatic moieties of ISSN 2166-0379 2017 hemicelluloses, cellulose, and lignin. The band at 1733 per cm is ascribed to stretching vibration of the carbonyl group (CO) of the cellulose and hemicelluloses in the bamboo fiber (El Oudiani et al, 2009;Herrera Franco and Valadez-Gonzailez, 2005).…”

The thermal degradation of matured 4-year-old culms of cultivated tropical bamboo Bambusa vulgaris was studied and analyzed. The analysis using the Fourier Transform Infrared Spectroscopy and Thermal Gravimetric Analysis revealed the presence of basic functional groups in the bamboo which consists mainly of ester, carbonyl, and hydroxyl groups. The chemicals present in the bamboo vary depending on the location of the samples taken from the bamboo culms. The moisture content and extractive were omitted in the kinetic study since they constituted less than 10% of the overall chemicals in bamboo and observed below 100℃. Low reactivity of lignin components and hemicellulose in bamboo occurred due to the peculiarities of the chemical structure and composition. The mechanism of the decomposition ISSN 2166-0379 2017 http://jas.macrothink.org 51 reactions taken as a three-step reaction which involved the activation energies and dynamics related to volatile fractions of hemicellulose, cellulose, and lignin. Activation energies of 46, 100, 105, 127, and 236 kJ/mol applied for all of the bamboos. The activation energy carried could provide better insight into the thermal decomposition process. It provides more information on critical energy needed to start a reaction. The decomposition activation energy range obtained could assist in understanding the thermal decomposition stability of the bamboo fibers and application in natural fiber reinforced polymer composite industry.

The grafting of vinyl monomers is an important method for replacing hydrophilic hydroxyl groups present on the surface of natural fibers by hydrophobic polymer chains. It improves the compatibility of natural fibers with polymer matrixes during the fabrication of natural-fiber-reinforced polymer composites. This article deals with the graft copolymerization of acrylonitrile onto Agave americana fibers in air in the presence of ceric ammonium nitrate as a redox initiator. A maximum percentage grafting of 24% was obtained after the optimization of various reaction parameters, including the reaction time, temperature, and concentrations of nitric acid, initiator, and monomer. The graft copolymers obtained under the optimum conditions were then subjected to the evaluation of different physicochemical properties, including swelling behavior in different solvents, moisture absorption behavior under different humidity levels, and chemical resistance. The graft copolymers were further characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, thermal analysis (thermogravimetric analysis/differential thermal analysis), and X-ray diffraction techniques.
