Kenaf fiber analysis

The aim of this study was extraction of cellulose from kenaf fiber which is available in Malaysia and preparation of nanocellulose whiskers from extracted cellulose in controlled hydrolysis condition. Chemical composition, size of particles, morphology, crystallinity, and thermal analysis of cellulose whiskers were investigated. [Pg.198]

The X-ray diffraction (XRD) measurements were performed on a Bmker AXS-D8 Advance model system. The diffracted intensity of Cn Ka radiation (0.154 nm, 40 kV and 40 mA) was measured in a 20 range between 10° and 70°. Ground kenaf fibers and hydrolyzed cellulose sample were subjected to crystallinity analysis. [Pg.199]

Reaction of kenaf with succinic anhydride were done in xylene at 120°C and WPGs up to 80% were achieved [32]. Dynamic mechanical analysis was done on acetone-extracted esterified fibers in the WPG range of 30-80. The data showed that there was a reduced transition temperature from about 170°C down to about 135°C and that there was no change in this first transition temperature as the WPG increases. The data showed that complete modification of that melting species had taken place at a WPG of m35. This thermal behavior is similar to reported trends observed for water-plasticized lignin in wood. [Pg.242]

A number of reviews have been studied on the potential of natural fibers such as sisal, kenaf, hemp, flax, bamboo, and jute for the preparation of thermoplastic composites. In this work, however sisal fiber (SF) has been used as reinforcement due to easily availability and comparatively low cost. The xmtreated and treated SF-reinforced RPP composites have been prepared and investigated their thermal, mechanical, morphological, weathering and impact properties. An improved mechanical, thermal, and morphological property has been observed for chemical treated SF as well as clay loaded RPP. The analysis revealed that SF-reinforced RPP composites with enhanced properties can be successfully achieved which warrants to replace the synthetic fillers-based conventional thermoplastic composites. These SF-based RPP composites can be the material of choice in the field of aeronautic, automobiles, civil engineering, etc., due to its low cost, low density, non-toxicity, recyclability, acceptable strength, high specific properties, and minimum waste disposal problems. [Pg.545]

No significant spectral changes in raw and electron beam-treated kenaf and henequen fibers were observed from ATR-FTIR measurement [43, 113]. However, from the earlier study using elemental analysis [111] and X-ray photoelectron spectroscopy (XPS) [15] by Cho et ul, it was pointed out that the [0]/[C] ratio of the electron beam-treated jute and henequen fibers was lower than that before the irradiation (OkGy). The ratio exhibited the lowest value at lOkGy [15, 111]. The decrease of the ratio after the irradiation indicated that the treated jute fibers have more hydrophobic character than the treated. It was suggested that the combination... [Pg.149]
