The same researchers successfully cubed bast fibers to a density of 0.89 g/cm 3, core fiber to a density of 1.22 g/cm 3, and whole stalk (bast and core) to a density of 0.93 g/cm 3.

The ESEM micrographs of A) Untreated kenaf fibre at 1500x magnification, KDC at 3000x magnification B), … Caulfield, G. Kovacsvolgyi, and B. Destree Abstract Considerable interest has been generated in the use of lignocellulosic fibers and wastes (both agri - cultural and wood based) as fillers and reinforce- ments in thermoplastics. Kenaf were separated from the outer layer and bast fibre and were cut usingcrusher . The first implementation of kenaf within a Ford vehicle was in the 2013 Ford Escape. Sawhney, E.J. In California, Texas, Louisiana and Mississippi, 3,200 acres (13 km²) of kenaf were grown in 1992, most of which was used for animal bedding and feed. The areal density of each woven kenaf mat and bamboo mat were 600 g/m 2 and 800 g/m 2 respectively. Kenaf [etymology: Persian],[2] Hibiscus cannabinus, is a plant in the family Malvaceae also called Deccan hemp and Java jute. R. Mahjoub. Additionally, as part of an overall effort to make vehicles more sustainable, Ford and BMW are making the material for the automobile bodies in part from kenaf. Composites Part A: Applied Science and Manufacturing, 41(10) (2010) 1329-1335. Charles L. Webber III and Venita K. Bledsoe. Kenaf Yield Components and Plant Composition . A three dimensional randomly oriented short kenaf fibre mat with a fibre diameter of approximately 0.1mm and an average fibre length of nearly 7mm was used for the production of samples as shown in Fig. Webster's Third New International Dictionary, Unabridged. The flowers are 8–15 cm diameter, white, yellow, or purple; when white or yellow, the centre is still dark purple. Steam was injected into the digester. H.P.S. Moreover, the combination of the natural fiber and the biodegradable polymer able to reduce the negative impact on human health. J. Shi, S. Q. Barnes, H. M. Horstemeyer, M. Wang, J. Hassan,M. [13] Panasonic has set up a plant in Malaysia to manufacture kenaf fibre boards and export them to Japan. Rozana Mohd Dahan, Ahmad Zafir Romli, Dr. Mohd Rozi Ahmad and Dzaraini Kamarun, https://doi.org/10.4028/www.scientific.net/AMR.1134.103. Kenaf seed oil is 20.4% of the total seed weight, similar to that of cotton seed. The ash content is removed by sieving and washing the fibre. They produced kenaf pellets over a range of 0.5 to 1.9 cm in diameter (Fig. D. K Visi D'Souza, N. Ayre, B. G. Webber Iii, C. L. Allen, M. S., Investigation of the bacterial retting community of kenaf (Hibiscus cannabinus) under different conditions using next-generation semiconductor sequencing. M. Zimniewska, M.

[7] Industrial Crops and Products, 29(2-3) (2009) 301-307. Results show that the presence of Kenaf fiber in concrete improved the properties such as splitting tensile strength, flexural strength and ultimate load of beam.

Paridah, Maznah , Effect of kenaf seed oil from different ways of extraction towards ovarian cancer cells. Fig. The kenaf fibres were processed through water retting, chemical retting and mechanical extractions. The pulp quality is similar to that of hardwood. The water retting method produces finer fibres between 3.2 to 3.7 Tex while other methods produces fibres between 4.0 to 5.0 Tex. springer, 17 (2010) 299–307. Kenaf is cultivated for its fibre in India, Bangladesh, United States of America, Indonesia, Malaysia, South Africa, Viet Nam, Thailand, parts of Africa, and to a small extent in southeast Europe. HISTORY. D.V. Danalatos, and S.V. Similarly, a continuous kenaf yarn with a diameter of approximately 1mm and PET yarn with a diameter of nearly 0.3 mm were also used as reinforcements. The kenaf fiber-reinforced polyurethane foam composite is characterized by a very low area density of less than 1 kg/m2 and high strength, making the door trim made of the fiber-reinforced kenaf polyurethane foam 30 percent lighter than that produced from conventional materials. Abstract. The bast fibre is made up of cellulose, hemicellulose and lignin with the value of (56-60%), (21-35%) and (8-15%) by weight respectively (Davoodi et al., 2010; Mazuki et al., 2011). David Brower, former Executive Director of the Sierra Club, in chapter 8 of his semi-autobiographical environmental book Let the Mountains Talk, Let the Rivers Run: A Call to Save the Earth (1995, Harper Collins), titled "Forest Revolution," advocated for kenaf paper use and explained its many advantages over wood pulp. Kenaf seed oil contains a high percentage of linoleic acid (Omega-6) a polyunsaturated fatty acid (PUFA). Kenaf [etymology: Persian], Hibiscus cannabinus, is a plant in the family Malvaceae also called Deccan hemp and Java jute. Today, while the principal farming areas are China and India, Kanaf is also grown in countries including the US, Mexico, and Senegal. Food and Bioproducts Processing, 89(4) (2011) 328-332. Physicothermal properties of the composites were studied at different percentages of compatibilizer contents using various techniques. Alpha-linolenic acid (C18:3) is present in 2 to 4 percent. A composite made from 100% carbon fibre was served for a comparison purpose. Amel, B. 2.1.1 Kenaf fiber. Kenaf Fiber/Polypropylene Anand R. Sanadi, J.F. In 1970, kenaf newsprint produced in the International Paper Company's mill in Pine Bluff, Arkansas, was successfully used by six U.S. newspapers. Hydrogen peroxide, an environmentally-safe bleaching agent that does not create dioxin, has been used with much success in the bleaching of kenaf. It is also useful as cut bast fibre for blending with resins in the making of plastic composites, as a drilling fluid loss-preventive for oil drilling muds, and for a seeded hydromulch for erosion control. [citation needed] J Ind Microbiol Biotechnol, 40(5) (2013). [7] Paper pulp is produced from the whole stem, and therefore contains two types of fibres, from the bast and from the core. The use of kenaf fiber can provide mechanical properties, i.e., tensile strength, comparable to those of synthetic fiber with lower density than traditional materials, resulting in lightweight and eco-friendly polymer composites.
