Chemical modification of kenaf fibers
Materials Letters, 2007The interest in using natural fibers in composites has increased in recent years due their lightweight, non-abrasive, combustible, non-toxic, low cost and biodegradable properties. However, lack of good interfacial adhesion, low melting point and poor resistance to moisture absorption make the use of natural fiber reinforced composites less attractive.

Bleaching of Kenaf and Cornhusk Fibers
Industrial & Engineering Chemistry Research, 2007Kenaf and cornhusk fibers have been bleached to CIE whiteness indexes of 66 and 74, respectively, without using any optical brighteners. A delignification process prior to bleaching has been used to partially remove the lignin from the fibers without affecting other fiber properties.

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.

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 ...

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).

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).
