“…Moreover, the intensity of the transmittance peak of 3328 cm -1 , the elimination of peak 3908 cm -1 and the shift in the peak of 3790 cm -1 indicate that the cellulose structure changed. This correlates to the work of several authors [22,[41][42][46][47], particularly with regards to mercerization removing non-cellulosic materials while changing the structure of cellulose. It can therefore be inferred from the FT-IR results that the OH groups of the mercerized H. sabdariffa fibers were activated to release active group for better interfacial bonding with the polymer matrix.…”

“…Furthermore, and as indicated in Table 2, the treatment of the fibers led to reduction in diameter of the fibers which may have improved the aspect ratio and more surface area for interaction between the fibers and denture acrylic resin hence, improved mechanical properties [18]. Also, mercerization treatment have eliminated hemicellulose and impurities from the fiber thereby roughening the surfaces, as seen in Figure 3 (B), exposing more reactive -OH group for better bonding with hydrophobic polymer [44,47]. This is further confirmed from the FTIR spectra ( Figure 5 (B)) with the disappearance of C=O peak at 1726 cm -1 and the decrease in intensity of peak 1246 cm -1 [22,46].…”

This study aimed to determine the characteristics of Hibiscus sabdariffa as a fiber-reinforcement material for denture acrylic resins. The Hibiscus sabdariffa fiber was extracted by hot water retting. The fiber was treated at room temperature in aqueous solution of NaOH for 8 hours at 8% concentration. Micrometre gauge and Field emission scanning electron microscope (FE-SEM), Archimedes principle, Fourier transform infrared (FTIR) spectroscopy, and Thermogravimetric analyser were used to characterize the diameter, morphology, density, water content and absorption, functional chemical component and thermal behaviour of Hibiscus sabdariffa fiber. In addition, the reinforcing characteristics of Hibiscus sabdariffa fiber was evaluated using denture acrylic resin. The flexural strength was measured in line with ASTM D 790 using Lloyd TM three point bending machine. In line with ASTM D 256, the impact strength was measured using Hounsfield TM charpy tester. The Micrometre gauge and FE-SEM analysis confirmed that diameter of Hibiscus sabdariffa fiber is within the range of other established reinforcing lignocellulosic fibers so also are the density, moisture content and absorption. The FTIR spectroscopy and TGA analysis confirmed the presence of cellulose, hemicellulose and other components in the fiber which were modified by treatment resulting in decreased hydrophilicity of the fibers thereby improving the thermal stability of the fiber. Furthermore, the bond fiber/matrix adhesion was improved which resulted in improve mechanical properties of the composite. The salient features of this study indicated that based on the suitable properties, Hibiscus sabdariffa fiber can be applied to reinforcing denture acrylics. In addition, and potentially, the use of Hibiscus sabdariffa fiber in reinforcement of denture acrylic resins can trigger further economic benefit while ensuring sustainable, green and safer environment.

Due to the dominating advantages of natural fibres such as biodegradability, eco-friendliness, nominal cost, low density and high specific strength, they are being used opposite to synthetic fibres in many industrial applications. Despite many advantages, these fibres face some limitations such as higher moisture uptake, quality variations, low thermal stability, and poor compatibility with polymeric matrix. To overcome these limitations, chemical treatments of these fibres were found to be the most suitable method to improve adhesion with polymers, increase their strength and water absorption resistance, and improve their composite properties also. Among chemical treatments, alkali treatment is the most widely used and versatile surface modification method of the natural fibres. A good number of research works have been carried out on effect of alkali treatment on the properties of natural fibres and its composites, which motivated for this review. In this paper, the effect of alkali treatment on the properties of natural fibres has been reviewed. In addition, the physical and mechanical properties, thermal analysis and tribological behaviour of its biocomposites are also reviewed. It was concluded that alkali treatment of natural fibres could provide enhanced properties of various bio-composites up to a great extent.

“…The peak at 896 cm -1 attributes C-H rocking vibrations assigned to β-glucosidic linkage. Similarly the peaks at 1421, 1369 and 1317 cm -1 present in raw fibre are associated with the bending vibrations of -CH 2, C-H, and C-O of cellulose [25,26]. Similarly the peak at 1020 cm -1 assigned to aromatic C-H in plane deformation and a peak at 1157 cm -1 C-O-C asymmetrical stretching in cellulose and hemicellulose.…”

Lignocellulosic fibres have been investigated to understand its influence on properties of textile fibres. Pandanus Odorifer (PO) is a leaf fibre which was mechanically extracted from the leaves of the plant using water retting extraction method. The chemical composition of the extracted fibres was determined using TAPPI method. The composition mainly consisted of cellulose 44±1%, hemicelluloses 30±1%, lignin21±1%, ash content 2.5±0.5%, and extractives around 2.5±0.5%, Structural analysis was carried out by FTIR, SEM, TGA, X-ray diffraction. Tensile and moisture content properties were also studied.
