Cellulose Microfibers from Salacca Midrib Fiber Isolated by the Mechanical Treatment

Abstract

Salacca midrib fibers are abundant natural waste in Turi, Sleman Regency, Daerah Istimewa Yogyakarta. Cellulose Microfibers from the salacca midrib fiber has been isolated by mechanical treatment and successfully has good physical characteristics. Cellulose fibers with micro sizes can strengthen the bond effect between the matrix and the fiber due to the vast contact area. The method for isolated cellulose microfibers by mechanical treatment for speed rotation of 5000, 10000 and 15000 rpm. Mechanical stirrer treatment aims to fibrillation and reduces fiber dimensions because of their high rotation. The characterization by XRD, FTIR, and SEM. The XRD results showed that the mechanical stirrer treatment did not damage the crystallinity index of cellulose microfibers. The crystallinity index of the raw material is 64.3%, increased to 79.1% for the microfiber cellulose crystallinity index. Identification of functional groups using FTIR did not show changes in cellulose compounds resulting from mechanical treatment. Morphological observation of fibers by SEM shows that the diameter cellulose microfibers size obtained from salacca midrib fiber ranges 5-10 µm with 100-300 µm in length. Cellulose microfibers have potential materials as reinforcement in the micro composite and extraction into nanocellulose materials.

Synthesis of cellulose nano fiber from palmyrah fruit fiber and its applicability as a reinforcement agent on starch based biodegradable film

“…The results revealed prominent characteristic diffraction peaks at 16.34°, 22.54°, 28.54°, and 34.9°. Among these peaks, those at 16.34°, 22.58°, and 34.9°, correspond to the crystallographic planes ( 110), ( 200) and ( 004) of cellulosic fiber, as documented by (Yudha et al, 2021) in their XRD analysis of salacca midrib fibers. The pattern consists of crystalline and amorphous peaks, which are types of semicrystalline material (Huang et al, 2020).…”

“…It divides three wavenumber regions: short IR (<400 cm -1 ), mid-IR (400-4000cm -1 ), and near IR (4000-13000cm -1 ) of the three types, the most widely used is the mid-IR spectrum, including in analyzing organic materials. Mid-IR is classified into four wavenumber regions [28], namely: (i) 2500-4000cm -1 there is single bond region (O-H, N-H, C-H) (ii) 2000-2500cm -1 there is triple bond region (C≡N, C≡C) (iii) 1500-2000cm -1 there is double bond band region (C=O, C=C, C=N) (iv) 600-1500cm -1 there is finger print region Figure 2 shows that two peaks appeared on the range absorbance between 4000-2500, there are 3410cm -1 , and 2924cm -1 shows the O-H stretching and H-bonded identified to alcohols and phenols groups and symmetric and asymmetric stretching C-H vibration shows acetyl groups [29][30][31]. The acetyl group is found in many tall plants and high trees.…”
