Thermal Characterization of Alkali Treated Kenaf Fibers and Kenaf-Epoxy Composites
Fibers and Polymers, 2018Chemical treatment of natural fibers is a well-defined means of mechanical property improvement in natural fiberreinforced composites. An understanding of mechanical and thermal properties in these media is essential for evaluating heat transfer, thermal degradation, and overall performance of these composites over their product lifetime. However, very

Chemical and Biological Retting of Kenaf Fibers
Textile Research Journal, 2006The physical and chemical characteristics of fibers after biological, chemical, and enzymatic retting were studied for kenaf cultivated in Jeju, Korea. Retting removes non-fibrous materials leaving separated fibers. Quantitative chemical analyses of kenaf fibers after retting were conducted using gas chromatography—mass spectrometry (GC— MS).

Mechanical properties of kenaf fibers and kenaf/PLA composites
Mechanics of Materials, 2008Abstract This paper describes the cultivation of kenaf and application to biodegradable composite materials. The unidirectional biodegradable composite materials were made from kenaf fibers and an emulsion-type PLA resin. Thermal analysis of kenaf fibers revealed that tensile strength of kenaf fibers decreased when kept at 180 °C for 60 min ...

Biodegradable Acetylated Kenaf Fiber Composites
Fibers and Polymers, 2021Bio-composites containing kenaf and starch as the filler and matrix, respectively, and Polyvinyl alcohol (PVA) and Polyethylene glycol (PEG) as plasticizers were fabricated. The acetylation of hydrophilic kenaf increased the hydrophobic matrix and surfactant bonding in the complex, and the starch matrix increased the biodegradability.

Carbohydrate Polymers, 2013
Biodegradable materials made from cassava starch and kenaf fibers were prepared using a solution casting method. Kenaf fibers were treated with NaOH, bleached with sodium chlorite and acetic buffer solution, and subsequently acid hydrolyzed to obtain cellulose nanocrystals (CNCs).

Study on microbe retting of kenaf fiber
Enzyme and Microbial Technology, 2007Retting is the predominant problem in the application of kenaf fiber in high-grade products. While the traditional retting method is water retting, that is, the harvested bast kenaf is immersed in natural water (rivers or tanks) in which indigenous bacteria colonize noncellulosic materials in an anaerobic process resulting in severe environmental ...

Kenaf Fibers for Tribo-Thermoplastic Composites
Volume 4: Design and Manufacturing, 2009In the present work, wear and frictional characteristics of thermoplastic epoxy resin reinforced with treated kenaf fiber (T-KFRE) is investigated. The T-KFRE composite was tested against smooth stainless steel using a block on disc (BOD) apparatus at 2.8m/s sliding velocity and variable applied loads (10–60N) and sliding distance (02.7km).

Frost kill and kenaf fiber quality
Industrial Crops and Products, 1999Abstract Kenaf (Hibiscus cannabinus) grown in northern Mississippi and elsewhere often is injured by early frost and killed before harvest. Frost kill often is associated with fungal growth or rot, so its effect on fiber quality is a major concern. Fiber processing also affects the quality and chemical composition of fibers. Therefore, this study was

Kenaf fiber reinforced composites: A review
Materials & Design, 2011Abstract The development of high-performance engineering products made from natural resources is increasing worldwide, due to renewable and environmental issues. Among the many different types of natural resources, kenaf plants have been extensively exploited over the past few years. Therefore, this paper presents an overview of the developments made

Improved Chemical Retting of Kenaf Fibers
Textile Research Journal, 2002Moldable nonwoven fabrics for automotive applications make up a large market, but they are currently made from synthetic fibers that are not easily biodegraded. Incorpo rating kenaf fibers into automotive nonwovens may enhance their biodegradability, while imparting improved acoustical insulation and reducing vehicle weight (kenaf fiber density is 1.4 ...
