Cell Wall Morphology, Chemical and Thermal Analysis of Cultivated Pineapple Leaf Fibres for Industrial Applications

Abstract

A study on chemical, morphology, and thermal analysis of cultivated pineapple leaf fibres (PALF) were carried out. The chemical compositions were determined by using Technical Association Pulp and Paper Industries standards. Fourier Transform-Infrared Spectroscopy analysis of PALF detect sharp band at 1,733 cm -1 , due to the absorption of carbonyl stretching of ester and carboxyl groups which is most abundant in pineapple leaf hemicelluloses. Cell wall ultra structure of PALF was studied by using Transmission electron microscopy. Transmission electron micrograph confirmed that cell wall structure of PALF consists of middle lamella, primary wall and secondary wall including S 1 , S 2 and S 3 layers. X-Ray Diffraction indicated that PALF have crystalline nature. Thermal analysis of PALF shows that T 10% and T 50% weight loss occurred at temperature of 212 and 306°C respectively. Differential Scanning Calorimetry of PALF showed the broad endothermic peak at a temperature of 80°C. The relationships between these properties were discussed and relate it with industrial application of pineapple leaf fibers.

Biopulp from Pineapple Leaf Fiber Produced by Colonization with Two White-Rot Fungi: Trametes versicolor and Pleurotus ostreatus

“…Nadirah et al (2012) and Khalil et al (2006), for example, reported holocellulose content close to 80% and lignin content of 10.5%, values which are slightly inferior to those found in this study (Table 1). Furthermore, in a study of 12 pineapple leaf fiber varieties from Brazil, slightly inferior values to those found in the present work were also reported (Neto et al 2015).…”

“…In this study, the holocellulose was similar, but the lignin content was higher (15.45%). Finally, regarding the content of extractives in ethanoltoluene and NaOH solution, these were similar to those reported by Khalil et al (2006), Nadirah et al (2012), and Daud et al (2014) in Malaysia and Neto et al (2015) from the 12 Brazilian varieties. As shown in this study, the white-rot fungi degraded lignin in PALF (Isroi et al 2011).…”

Oil Palm Biomass Fibres and Recent Advancement in Oil Palm Biomass Fibres Based Hybrid Biocomposites

“…Oil Palm/Glass Polyester Oil palm/Sisal Natural rubber Jacob et al 2004a,b;Jacob et al, 2005;Jacob et al 2006a,b,c,d;Jacob et al 2007; Oil Palm/Jute Epoxy Jawaid et al, 2010;2011a-g;Khalil et al, 2011 Oil Palm/Kalonite Polyurethane Anuar and Badri, 2007 …”

“…Research output show that dimensional stability, density, void content, and chemical resistance of oil palm EFB fibres reinforced epoxy composite improved with hybridization of oil palm EFB fibres with non woven/woven jute fibres (Jawaid et al 2011d,f,g;Abdul Khalil et al 2011). Hybridization of oil palm EFB composites with jute fibres improved physical properties of oil palm/jute hybrid composites due to packed and hybrid arrangement of fibre, less hydrophilic nature of jute fibres, better jute/epoxy interaction.…”

“…have been in considerable demand in recent years due to their eco-friendly and renewable nature. Natural fibres received considerable attention as potential reinforcements in polymer composites (Wong et al 2010;Wan Nadirah et al 2011;Bledzki and Gassan 1999). The attraction towards utilization of natural fibres as a reinforcement of polymer-based composites is mainly due to their various advantages over synthetic fibres such as are low density, lower cost, light weight, high strength to weight ratio, biodegradability, acceptable specific properties, better thermal and insulating properties (Rout et al 2001;Rana et al 2003;Joshi et al 2004;Nayak et al 2009).…”
