Bleaching of Kenaf and Cornhusk Fibers

Industrial & Engineering Chemistry Research, 2007
Kenaf 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, 2018
Chemical 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

Study on microbe retting of kenaf fiber

Enzyme and Microbial Technology, 2007
Retting 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 ...

Chemical and Biological Retting of Kenaf Fibers

Textile Research Journal, 2006
The 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).

Kenaf fiber reinforced composites: A review

Materials & Design, 2011
Abstract 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

Frost kill and kenaf fiber quality

Industrial Crops and Products, 1999
Abstract 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 Fibers for Tribo-Thermoplastic Composites

Volume 4: Design and Manufacturing, 2009
In 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).

Improved Chemical Retting of Kenaf Fibers

Textile Research Journal, 2002
Moldable 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 ...

Kenaf—fiber-plant rival of jute

Economic Botany, 1947
In India and other parts of the Old World kenaf has long been of value in the manufacture of gunny cloth, cordage, fishing nets, floor matting and rug backing, and since 1941 investigations have been conducted toward its cultivation in the New World.

The isolation and characterization of lignin of kenaf fiber

Journal of Applied Polymer Science, 2009
AbstractIn this article, milled wood lignin (MWL) was isolated and purified from retted kenaf fiber, the lignin obtained was characterized by elemental analysis, FTIR, 1H‐NMR, and 13C‐NMR spectroscopy. The C9 formula is calculated for kenaf fiber MWL as C9H9.32O3.69(OCH3)1.30.
