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. Calamari, A.P.S. Effects of kenaf core and bast fibers as dispersing phases on low density fiberboards (engineered wood) B.U. Rigsby, Optimization for enzyme-retting of flax with pectate lyase. The fibres in kenaf are found in the bast (bark) and core (wood). Other names include Bimli, Ambary, Ambari Hemp, Deccan Hemp, and Bimlipatum Jute. The pulp quality is similar to that of hardwood. Danalatos, and S.V. In contrast, 1-acre (4,000 m2) of forest (in the US) produces approximately 1.5 to 3.5 tons of usable fibre per year. [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. They found that kenaf newsprint[10] made for stronger, brighter and cleaner pages than standard pine paper with less detriment to the environment. Kenaf fibre was mixed with Polypropylene (PP) in addition of maleic anhydride (MAPP). D.V. 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. These textile products are aesthetically pleasing, strong, lightweight, and have an excellent soft feel. J.C. Villar, Revilla, E. Gomez, N. Carbajo, J. M.

The main attraction of the kenaf plant is the bast fibres because of their specific high strength to low … [9] Kenaf Edible Seed Oil Contains: The most common process to make kenaf paper is using soda pulping before processing the obtained pulp in a paper machine. In 1970, kenaf newsprint produced in the International Paper Company's mill in Pine Bluff, Arkansas, was successfully used by six U.S. newspapers. H.P.S. The core is about 60% of the plant and has thick (≈38 µm) but short (0.5 mm) and thin-walled (3 µm) fibre cells. 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. Parikh, T.A. Due partly to kenaf fibres being naturally whiter than tree pulp, less bleaching is required to create a brighter sheet of paper. Construction and Building Materials, 25(4) (2011) 1991-(2001). Fig. In order to modify and possibly improve the adhesion between the fibers and the matrix, the fibers … Many of the facilities that now process Southern pine for paper use can be converted to accommodate kenaf. Hybrid composites of wood flour/kenaf fiber and polypropylene were prepared at a fixed fiber to plastic ratio of 40 : 60 and variable ratios of the two reinforcements namely 40 : 0, 30 : 10, 20 : 20, 10 : 30, and 0 : 40 by weight. Hibiscus cannabinus is in the genus Hibiscus and is native to southern Asia, though its exact origin is unknown.The name also applies to the fibre obtained from this plant. The fibre diameters from the different retting and extraction methods vary from 33 to 134 m and did not show to have any relationship with fibre fineness. A. Paridah, M Tahir Sudin, R. Anwar, UMK Hussein, S. Ahmed, Effect of fibre extraction methods on some properties of kenaf bast fibre. [6] The individual fibre cells are about 2–6 mm long and slender. In 1960, the USDA surveyed more than 500 plants and selected kenaf as the most promising source of tree-free newsprint. Again in 1987, a Canadian mill produced 13 rolls of kenaf newsprint which were used by four U.S. newspapers to print experimental issues. J. Zhang, H. Zhang, and J.

Panasonic has set up a plant in Malaysia to manufacture kenaf fibre boards and export them to Japan. [6] The name also applies to the fibre obtained from this plant. Moreover, the combination of the natural fiber and the biodegradable polymer able to reduce the negative impact on human health. The main uses of kenaf fibre have been rope, twine, coarse cloth (similar to that made from jute), and paper. The kenaf fibres were processed through water retting, chemical retting and mechanical extractions. International Journal of Polymer Science, (2011) 1-8. They produced kenaf pellets over a range of 0.5 to 1.9 cm in diameter (Fig. [7] Paper pulp is produced from the whole stem, and therefore contains two types of fibres, from the bast and from the core. 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. ever, due to the lower density of kenaf fibers this ratio was increased. First grown in Egypt over 3000 years ago, the leaves of the kenaf plant were a component of both human and animal diets, while the bast fibre was used for bags, cordage, and the sails for Egyptian boats. Obendorf, Chemical and Biological Retting of Kenaf Fibres. Kenaf fiber is usually reinforced with synthetic based polymer resin such as polypropylene. Foulk, R.B. [12]. [19] [7] The leaves are 10–15 cm long, variable in shape, with leaves near the base of the stems being deeply lobed with 3-7 lobes, while leaves near the top of the stem are shallowly lobed or unlobed lanceolate. 2.1.1 Kenaf fiber. Printing and writing paper made from the fibrous kenaf plant has been offered in the United States since 1992. 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. N.G. Long slender primary fibers on the outer portion of the stalk characterize bast fiber plants. The fruit is a capsule 2 cm diameter, containing several seeds. The kenaf fibres were processed through water retting, chemical retting and mechanical extractions. The bulk density of the fibers used was 1.2 g/cm3.

Archontoulis, Growth and biomass productivity of kenaf (Hibiscus cannabinus, L. ) under different agricultural inputs and management practices in central Greece. Merriam-Webster, 2002. In Asia, kenaf is cultivated predominantly for the fibre, the extraction process involves soaking the stalks (the retting process) and manual removal of the fibres. 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). The stems produce two types of fibre: a coarser fibre in the outer layer (bast fibre), and a finer fibre in the core. The MOR of kenaf and market MDF was 44.97 and 40.65 N mm -2, respectively. J Ind Microbiol Biotechnol, 40(5) (2013). The flowers are 8–15 cm diameter, white, yellow, or purple; when white or yellow, the centre is still dark purple.

The fineness and morphology of kenaf fibres are the main focus of this paper. J. Summerscales, J. Dissanayake, N. P. J. Virk, A. S. Hall, Wayne, A review of bast fibres and their composites. Various reports suggest that the energy requirements for producing pulp from kenaf are about 20 percent less than those for wood pulp, mostly due to the lower lignin content of kenaf. M.J.J.H.A. The density of these materials will determine how light the final product will be and especially important when making sports equipment that involves speed. According to Miyake and Suzuta (1937), there are more than 129 names for kenaf worldwide. Y.A. The bast fibres are used to make ropes. as a composite. [2] The MOE for kenaf and market MDF was 3786 and 3518 N mm -2, respectively. W. Jinhua and G.N. R. Mahjoub. Over 20 years, 1-acre (4,000 m2) of farmland can produce 10 to 20 times the amount of fiber that 1-acre (4,000 m2) of Southern pine can produce. The first novel to be published using 100% kenaf paper was The Land of Debris and the Home of Alfredo by Kenn Amdahl (1997, Clearwater Publishing Company). It is an annual or biennial herbaceous plant (rarely a short-lived perennial) growing to 1.5-3.5 m tall with a woody base. [11] R. Yatim, J. M. Sam, A. R. M. Hashemi, S.
