“…These peaks are found in native cellulose (cellulose I), where the first peak is associated with (1 false1¯0) and (110) crystallographic planes overlapping, and the second is (002) crystallographic plane of cellulose structure. 53 , 54 The Segal method was employed to calculate the crystallinity index (CI), and after alkali treatment the peaks intensity rose, increasing CI values from 36% to 47%, for PR and MPR, respectively. These observations are consistent with the removal of amorphous components, such as lignin and hemicellulose, as reported by Mulinari et al.…”

Australian palm residues are generated by palm heart industry in large quantities and are considered an underused material with a composition rich in lignocellulosic structures. This residue is generally utilized as briquettes for energy or sheep feed; however, few works investigate this residue as composite fillers. This work aimed to revalue Australian palm residues (PR) by preparing polypropylene composites through melt mixing, using different fiber contents (0, 5, 10, 20, and 30 wt%), and evaluate the statistical influence of fibers (residues) alkali treatment (MPR) in composites mechanical properties. PR and MPR were evaluated by FTIR, XRD, SEM, TGA, and composites were assessed using thermal and mechanical analysis, in which ANOVA statistical analysis was applied. The residues addition increased the mechanical properties and their treatment enhanced the stiffness of the composites compared to pristine PP. However, ANOVA demonstrated that at low residues contents, surface treatment does not increase fiber-matrix interactions effectively, then tensile properties were statistically similar to PP. Considering tensile properties, 20% MPR showed statistically distinct properties, with significative enhancements; no filler contents dependence was verified. Flexural properties were more sensitive to residue loading, and composites with 30% PR and MPR presented superior mechanical performance. This difference is associated with a higher sensitivity of tensile stress towards fiber-matrix interactions, which was improved with fiber treatment. Also, the residues content and treatment influenced the composites' thermal stability, with better results for PP-MPR. Results indicate that palm residue is an excellent filler for improving composites' thermal and mechanical properties, with a greener character.

“…Figure 6 (a) shows the SEM micrograph of untreated bers, the surface of IVs showed absence of impurities such as wax and grease, and internal brils [40]. At higher magni cation, Figure 6 (b) shows that the removed waxes and oils from the bers' surface were removed by 3% alkaline treatment, thus enable surface roughness on the ber surface [41,42]. The alkaline treatment showed the differences compared to raw ber.…”

This research aims to analyze the newly discovered cellulosic ber from the bark of Dittrichia viscosa, or Inula viscosa (IV), and evaluate the effects of permanganate and alkali chemical treatments on the physical properties to improve the interfacial bonding between Inula viscosa reinforced polymer composites. These permanganate and alkali treatments are both e cacious in helping in reducing hydrophilicity and eliminating impurities from the ber surface, which has been con rmed by scanning electron microscope (SEM) observation, thermogravimetric analysis (TGA), X-ray diffraction (XRD), and Fourier Transform Infrared Spectrometry (FTIR). Permanganate-treated IVFs have shown higher tensile strength and interfacial stress resistance (IFFS) than alkaline IVFs, and untreated IVFs by tensile and droplet tests. The different characteristics were studied and compared with other bark bers already available. It is estimated that the ber treatments will enable high-quality IVF-reinforced polymer composites for use in the industry.

“…Furthermore, the CS value for UEB, UER, TEB3N8h and TER3N4h was found to be 2.83 nm, 2.84 nm, 3.12 nm and 3.09 nm, respectively. The optimization of Cr.I., Xc and CS after alkaline treatment has been found in previous studies for different fibers such as date palm branches (Amroune et al 2019), Washingtonia palm (Sajid et al 2019), Mendong grass [31], banana pseudostems (Das et al 2018), jute fiber (Roy et al 2012) as shown in Table 5.…”

“…However, as shown in Figure 1, date palm tree is constituted by six different parts (rachis, leaflets, petiole, fruit branches, mesh and trunk) and each part is composed by fibers with different composition and architecture. Therefore, all these different parts produce a significant amount of waste, totaling more than 800,000 tons per year in Algeria alone (Agoudjil et al 2011;Amroune et al 2019).…”

Alkali treatment effect on physicochemical and tensile properties of date palm rachis fibersABSTRACT: This work aims to optimize the physico-chemical and tensile properties of vascular fibers extracted from a local date palm rachis in Algeria. This fiber has a very specific composition and architecture and is different from the remaining fibers obtained from the six possible parts of the tree. For this purpose, a Taguchi orthogonal array design L16 was applied to reduce the number of experiments. The fibers were extracted from the rachis with two different methods (boiling and retting in water) and treated by NaOH with various concentrations (1%, 2%, 3%, and 5%) and for different durations (1, 4, 8 and 12 hours). They were characterized using SEM-EDX, ATR-FTIR, XRD and TGA to understand the effects of the extraction method and alkali treatment. A statistical treatment of the data was carried out based on the S/N ratio and ANOVA was performed to identify the most significant parameters affecting the tensile strength and the Young's modulus of the fibers. A desirability function was developed to identify the optimal factors leading to the maximization of the tensile properties.
