“…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.

“…Although numerous studies have been dedicated to the application of coconut shell agro-waste and surface treatment of natural materials, the impact of various chemical surface treatments on surface morphology, thermal stability, and chemical characteristics of coconut shell powder/ ller has seldom been investigated and reported. Actually, subjecting natural materials to different chemical surface treatments results in different bre properties [30]- [32]. Therefore, in this paper, a research attempt is made to enhance the thermal stability, morphological, and chemical properties of coconut shell powder by different surface treatments.…”

The use of environmentally friendly materials for industrial applications has increased tremendously in the past decades due to environmental concerns and the problems associated with the use of synthetic materials. Coconut shell is an agro-waste and source of biomass that has attracted increasing research attention as a potential alternative reinforcing material to synthetic. This study considered chemical modification and characterization of coconut shell powder in an attempt to enhance compatibility with the hydrophilic polymer matrix. The coconut shell powder was treated with alkali (NaOH), bleaching and combined NaOH-bleaching solutions before investigating the surface morphology, chemical transformations, and thermal stability. It was discovered from the results that combined treatment gave the optimum enhancement. The surface treatments resulted in chemical transformations of coconut shell powder, while FTIR analysis confirmed partial removal of lignin and hemicellulose. Also, XRD investigation revealed that surface treatments enhanced the crystallographic properties, whereas TGA analysis showed that the thermal stability of the treated sample was enhanced. Hence, treated coconut shell powder can be considered a sustainable and environmentally friendly reinforcing material for lightweight polymer composites needed for industrial applications, such as automotive dashboards and panels.

“…Scanty and sporadic work has been done on different treatments of banana fibre using biocatalysts/chemicals and its effect on optical, physical and structural properties, 14,15 but scientific report on bleaching of banana fibre using peracetic acid (PAA) is not reported elsewhere to the best of our knowledge. The novelty of the work is a systematic study on bleaching of banana fibres using PAA, varying the three important process parameters to make the fibre whiter (WI > 70), acceptable for subsequent dyeing or printing operation.…”

“…Conventional hydrogen peroxide bleaching is generally carried out to achieve good whiteness index (WI > 70-85), but it also leads to high loss in tensile strength, as the process is carried out at highly alkaline condition at the elevated temperature of 80-90 C. In addition to widely adopted hydrogen peroxide bleaching of textile, peracetic acid bleaching of jute and other fibres has also been reported to produce fibre with sufficient WI, while retaining maximum strength. 13 Scanty and sporadic work has been done on different treatments of banana fibre using biocatalysts/chemicals and its effect on optical, physical and structural properties, 14,15 but scientific report on bleaching of banana fibre using peracetic acid (PAA) is not reported elsewhere to the best of our knowledge.

Banana is an important commercially available natural fibre, suitable for making coarse yarns. It has also potential for making fine home and apparel textiles after requisite chemical intervention or blending with other fine fibres. For making such products, chemical processing, namely bleaching, coloration and finishing, play an important role. Bleaching of fibre is generally carried out in highly alkaline condition and at high temperature of 85°C using hydrogen peroxide to achieve whiteness index of > 70 with about 25% loss in tensile strength. To achieve a similar whiteness index, while addressing strength loss, a fibre friendly low‐temperature low‐alkali based peracetic acid (PAA) bleaching of banana fibre has been proposed in the present article. Important bleaching process parameters, namely PAA concentration (10–30 g/L), time (60–180 min) and temperature (60–80°C), have been varied for optimisation of the bleaching process. Banana fibre bleaching using PAA concentration of 20 g/L at 70°C for 2 h can produce fibre with whiteness index of > 70, which is suitable for subsequent coloration. The PAA bleached banana fibre can retain 84% of its bundle strength and 95.6% of its weight. Physical (strength, fineness), chemical (attenuated total reflectance Fourier‐transform infrared [ATR‐FTIR], energy dispersive X‐ray spectroscopy [EDX]), optical (colour) and morphological (scanning electron microscopy [SEM]) properties of banana fibres before and after bleaching were evaluated to study the efficacy of the process.
