Physicothermal properties of the composites were studied at different percentages of compatibilizer contents using various techniques. Textile Research Journal, 72(7) (2002) 618-624. 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. Kenaf Yield Components and Plant Composition . In 1970, kenaf newsprint produced in the International Paper Company's mill in Pine Bluff, Arkansas, was successfully used by six U.S. newspapers. And bast fibre in kenaf makes up 35–40% of stem weight and can be processed into high‐quality industrial materials because of its low content of woody impurities and pectin (Xiong, 2008). Other names include Bimli, Ambary, Ambari Hemp, Deccan Hemp, and Bimlipatum Jute. [14] Kenaf matures in 100 to 200 days. The main attraction of the kenaf plant is the bast fibres because of their specific high strength to low … The ESEM micrographs of A) Untreated kenaf fibre at 1500x magnification, KDC at 3000x magnification B), and C) Rod-like structure of KDC at 275x magnification. The kenaf fibres were processed through water retting, chemical retting and mechanical extractions. Materials & Design, 58 (2014). 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. Parikh, T.A. [7] Paper pulp is produced from the whole stem, and therefore contains two types of fibres, from the bast and from the core. J. Summerscales, J. Dissanayake, N. P. J. Virk, A. S. Hall, Wayne, A review of bast fibres and their composites. J. Shi, S. Q. Barnes, H. M. Horstemeyer, M. Wang, J. Hassan,M. 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. Merriam-Webster, 2002. El-Shekeil, Sapuan, S. M. Jawaid, M. Al-Shuja'a, O. M. Influence of fibre content on mechanical, morphological and thermal properties of kenaf fibres reinforced poly(vinyl chloride)/thermoplastic polyurethane poly-blend composites. There is no fiber treatment for both mats. Cellulose, 21(1) (2014) 569-579. "kenaf." [citation needed], An area of 1-acre (4,000 m2) of kenaf produces 5 to 8 tons of raw plant bast and core fibre in a single growing season. [1] Dodd, L.L. Composites Part A: Applied Science and Manufacturing, 41(10) (2010) 1329-1335. The bulk density of the KDC was 0.04 g/cm3. Hydrogen peroxide, an environmentally-safe bleaching agent that does not create dioxin, has been used with much success in the bleaching of kenaf. The MOE for kenaf and market MDF was 3786 and 3518 N mm -2, respectively. Akin, B. Condon, Brian, M. Sohn, J.A. Paridah, Maznah , Effect of kenaf seed oil from different ways of extraction towards ovarian cancer cells. Hemp is also one of the bast fibers known to ancient Asians, long before the birth of Christ. For over 6000 years kenaf (Hibiscus cannabinus L., Malvaceae) was primarily used as a cordage crop and secondarily as a livestock feed (Dempsey 1975).In the wet-retting process the long, strong bark fiber strands were separated from the remaining bark material by a natural bacterial wet … M.J.J.H.A. E-glass fiber possesses the highest density while Jute having the lowest, whereas Kenaf fibers is in the middle range density. [6] The individual fibre cells are about 2–6 mm long and slender.
