“…Pineapple leaf fiber had a much lower absorption of 192.821% owing to its contrasting lignocellulosic content. The water absorption values obtained for banana as well as pineapple leaf fibers are in accordance with the study ofBegum et al (2021). U R E 4 Water absorption behavior and dimeter of extracted fibers extracted from five banana (B 1 , B 2 , B 3 , B 4 , B 5 ) and one pineapple (P) samples.3.4.2 | Tensile strengthThe tensile properties of the test samples are shown in Figure5a,b.Among the banana samples, B 5 (Padathi) had the highest tensile strength of 79.8 MPa, while B 2 (Palayamkodan) had the lowest tensile strength of 45.82 MPa.…”

Demand for natural fibers as an alternative to synthetic fibers is on the rise. Constraints of current fiber extraction units are limited to single raw material and has low energy efficiency. Hence, this study was taken up for the design and development of a multiple fiber extractor, modelling and optimization of the machine operating parameters, and economic analysis of the developed prototype. The designed machine operates based on the raspador principle. Box Behnken design (BBD) and artificial neural network (ANN) were used to evaluate the performance and optimize the variables of the designed multiple fiber extractor. The input variables included roller speed (550, 735, and 920 rpm), gap/clearance of the roller (2, 3, and 4 mm) and the pitch/distance between the spline slots (0.5, 1.5, and 2.5 mm), while the output variables were yield (kg), capacity (kg/h), energy consumption (kJ), and efficiency (%).The prediction accuracy of quadratic models (R 2 = 0.962-0.985) developed in BBD were better than the ANN models (R 2 = 0.831-0.946). The optimized combination was found to be 714.23 rpm roller speed, 3.12 mm gap, and 1.49 mm pitch of the blade, which yielded (1.48 kg) a desirability value of 0.95. The XRD results indicated the highest crystallinity index was recorded for Pineapple leaf fiber compared to banana fiber. SEM results revealed that extracted BF having typical network structure (cellulose, hemicellulose, lignin, and waxes) compared to smooth PLF (lignin and hemicellulose). The fibers extracted using the developed machine was utilized for making biodegradable cutlery. Practical ApplicationsThis study was taken up to design a multifiber extractor, to extract fibers from agricultural residues after their useful parts are taken for consumption or processing.Thus, a single machine capable of handling multiple byproducts can utilize those residues, which were previously discarded as waste. Moreover, the extracted fibers are used for the manufacture of biodegradable cutlery. With a small investment, this machine can provide an additional income to the farmers, along with taking away the concern regarding waste disposal.

“…Due to a large number of void spaces in between fibre bundles, natural fibres have an inherent capacity to hold moisture. Therefore, natural fibres have greater moisture retention than synthetic fibres [41]. Sugarcane fibres are such natural fibres that have higher moisture absorbing ability due to the presence hydrolytic hemi cellulosic bonds [42].…”

This study addresses environmental concerns related to sugarcane biomass as an industrial fuel source by exploring its potential for textile applications. Bagasse undergoes sequential alkali-H2O2 treatment, followed by varying concentrations of silicone softener (50g/L - 100g/L - 150g/L). The goal is to enhance fiber fineness and softness. Comprehensive physical and chemical characterization reveals significant alterations in treated fibers, impacting surface morphology, crystallinity, linear density, and moisture regain. Results indicate a decline in fiber linear density from 59.47tex to 48.84tex, thus improved fineness, moisture regain initial from 6.9% to 4.7%, reduced crystallinity, and enhanced mechanical strength with silicone softener treatment. Treated fibers show promise as a sustainable alternative to conventional cotton, emphasizing the importance of sugarcane biomass for eco-friendly textile manufacturing.

“…Also after treatment cracks and pores increases on the surface of fiber so it can hold more water into it. 6 The use of resin helps to fill the cracks and increase the strength of the composite by providing a more uniform surface area, which reduces the amount of stress concentrations. When the resin fills the cracks, it can reduce water absorption.…”

The development of natural fiber reinforced composite material is increasing at very fast rate due to their eco-friendly and biodegradable nature. NFCs natural fiber reinforced composites have various properties such as low cost, low density, recyclability, renewability and good physical and mechanical strength. NFCs have wide range of applications such as in automobile, sports, aerospace, marine, home appliances and in building construction. In this paper we used prosopis juliflora desert plant fibers as a filler to make biodegradable composites and alkali treatment was done to modification of fiber in order to make high strength composites materials. By using scanning electron microscopy (SEM), water absorption tests, and Fourier transform infrared spectroscopy (FTIR), this paper examines the effects of surface modification on the fibers. By conducting SEM analysis it has been observed that the chemical treatment of fibers can improve adhesion of the composites. Water absorption test concluded that due to the higher porosity and better surface energy of the treated fiber it had a higher rate of water absorption than the untreated fibers. FTIR results concluded that due to more crystalline structure and more ordered structure crystallinity index of the treated fibers increases compared to untreated fibers. FTIR results proves that TCI total crystallinity index and the LOI lateral order index is high for PJ treated fibers as compared to untreated PJ fibers.
