“…This treatment removes a portion of the lignin, wax, and oils which cover the outside of the ber cell wall, depolymerizes cellulose, and reveals the crystalline phase. The incorporation of sodium hydroxide to natural ber encourages the ionisation of the hydroxyl group, resulting in the formation of the alkoxide [39]. The bre with much more hydrogen clusters would be more coherent with the epoxy matrix.…”

Bamboo is an ancient structural material used for a variety of applications in India. Bamboo is widely used in the global south for frames, bridges, housing, and transitory structures. Bamboo supply has been effectively inexpensive as well as plentiful in global south countries to meet the widespread need for affordable housing. The current research focuses on the mechanical properties of bamboo fibre reinforced polymer composite materials for use in structural industries. Moreover, a bamboo fibre reinforced composite was compared to glass fibre in a variety of ways, and it was discovered that the bamboo fibre composite outperformed the glass fibre in a few areas. Investigations revealed the potential use of bamboo fibre reinforced composite with good stiffness but a lower strength limitation than glass fibre composite. Tensile strength of 40.53 MPa and hardness value of 68.2 RHN were achieved by E-glass epoxy composites. However, the results of bamboo fibre reinforced composites cannot be overlooked. Further research was conducted to improve the mechanical properties, and the results were satisfactory.

“…After the treatment of fibers by any of these methods, all treated fibers are washed away before drying [32][33][34][35][36][37]. The moisture content in fiber affects its quality, so proper drying is critical.…”

The textile fiber market is dominated by synthetic fibers and costly natural fibers. The dual perspective with regards to finding substitutes for costly natural fibers and disadvantages due to environmental burden cum health problems by synthetic fibers need to be addressed as both entail sustainable improvement of the textile industry. The potential route for tackling such problems is utilizing unlimited plant resources in developing countries like Ethiopia. The objective of this study is to extract, characterize, and chemically treated xanthium oriental bast fiber extracted from the plant using the conventional water retting method. In the invitation, the experimental design was based on Central Composite Design (CCD) method, and treatment parameters were selected, specifically NaOH concentration, and treatment temperature. Analysis of variance (ANOVA) was used to analyze the significance of the results. The chemical composition analysis revealed 72% cellulose, 18% hemicellulose, and 10% lignin. Xanthium oriental fiber has a diameter of 26.85 μm, a fineness of 1.76tex, and a length of 110–145 cm with reduced values for fiber treated at different alkali concentrations. The moisture content of the extracted fiber was 12.74%. The raw fiber sample showed lower crimp (1.04%) as compared with those treated at different caustic soda concentrations. Moreover, scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and Fourier transform infrared spectroscopy (FTIR) was used to analyze the changes in surface, weight loss, and composition of xanthium oriental bast fiber treated with alkali under optimum conditions compared with untreated to obtain a deeper insight into the influential mechanisms of alkali treatment.

“…The standard mercerization process, ASTM D 1695 was adopted for the mercerization of the microcrystalline cellulose. Thus, the sample was treated with a very concentrated sodium hydroxide which resulted in the significant swelling, changes to the fine structure, size, shape, and mechanical properties of MCC (Ernest, & Peter, 2022). The mercerized MCC (100g) was kept at room temperature for further use.…”

There is a greater need for the identification and monitoring of metal contaminants as a result of the growing hazard that heavy metal contamination of water poses to the environment. In this work, microcrystalline cellulose was functionalised with ethylenediaminetetraacetic acid, and the product analysed using scanning electron microscopy and X-ray diffraction techniques. The functionalised microcrystalline cellulose-ethylenediaminetetraacetic acid was employed to modify the glassy carbon electrode. Detection for Pb2+ and Cd2+ ions was determined using square wave anodic stripping voltammetric analysis at square wave potential scan of -1.0 V to -0.2 V, and deposition potential of -1.0 V in 0.1M acetate buffer for 240 sec. Higher current response of Pb2+ was obtained at -0.6 V and that of Cd2+ at -0.8V. Limit of detection for Pb2+ was 1.8 ppb (MCC-EDTA GCE) and 5.0 ppb (MCC-GCE) , while that of Cd2+ was 7 ppb (MCC-EDTA GCE) and 10 ppb (MCC-GCE), these indicate MCC EDTA GCE has higher sensitivity towards detection of the metal ions and selectivity of modifiers for detection of Pd2+ and Cd2+ was achieved successfully.
