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. 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. This method has been found to give superior reinforcement quality. "Crude fibre" separated from the bast is multi-cellular, consisting of several individual cells stuck together. These textile products are aesthetically pleasing, strong, lightweight, and have an excellent soft feel. They produced kenaf pellets over a range of 0.5 to 1.9 cm in diameter (Fig. The ESEM micrographs of A) Untreated kenaf fibre at 1500x magnification, KDC at 3000x magnification B), … 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). M. Paiva, M. Ammar, I. Campos, A. Cheikh, R. Cunha, A., Alfa fibres: Mechanical, morphological and interfacial characterization. Kenaf were separated from the outer layer and bast fibre and were cut usingcrusher . The bast fibres are used to make ropes. The pulp quality is similar to that of hardwood. Sawhney, E.J. Industrial Crops and Products, 25(2) (2007) 136-146. 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. The density of these materials will determine how light the final product will be and especially important when making sports equipment that involves speed. The fineness and morphology of kenaf fibres are the main focus of this paper. S. Kyung Hun, S.K. and form the outer-layer of the stalk. 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. Stryjewski, Improved Chemical Retting of Kenaf Fibres. R. Yatim, J. M. Sam, A. R. M. Hashemi, S. Hamid, Tensile properties of kenaf fibre due to various conditions of chemical fibre surface modifications. The areal density of each woven kenaf mat and bamboo mat were 600 g/m 2 and 800 g/m 2 respectively. The kenaf fibres were processed through water retting, chemical retting and mechanical extractions. [10] Anyanwu et al-This content was downloaded from IP address 40.77.167.75 on 24/04/2020 at 01:47. 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. L.S. N.G. 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. Dodd, L.L. J. Zhang, H. Zhang, and J. Zhang, Evaluation of liquid ammonia treatment on surface characteristics of hemp fibre. The bulk density of the KDC was 0.04 g/cm 3. The first implementation of kenaf within a Ford vehicle was in the 2013 Ford Escape. 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. However, recent studies tend to concern towards the environmental issues which kenaf fiber act as an alternative natural fiber competitor. The kenaf fibres were processed through water retting, chemical retting and mechanical extractions. [18] It was probably used first in Asia. Textile Research Journal, 76(10) (2006) 751-756. The stems are 1–2 cm diameter, often but not always branched. [15] Kenaf is one of the allied fibres of jute and shows similar characteristics. springer, 17 (2010) 299–307. Screen, M. Warnock, D.H. Muller, D.D. Danalatos, and S.V. Cellulose, 21(1) (2014) 569-579. Hunt, D.F. ever, due to the lower density of kenaf fibers this ratio was increased. Blanchard, F. J. Industrial Crops and Products, 32(3) (2010) 231-240. 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. Fig. J.C. Villar, Revilla, E. Gomez, N. Carbajo, J. M. Simon, Improving the use of kenaf for kraft pulping by using mixtures of bast and core fibres. [citation needed] 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. Linoleic acid (C18:2) is the dominant PUFA, followed by oleic acid (C18:1). Yaza, L. S. Foo, J. The fibres in kenaf are found in the bast (bark) and core (wood). H.P.S. Calamari, A.P.S. The kenaf fibers used in this study were ob-tained from National Tobacco Board at Kelantan, Malaysia. Rigsby, Optimization for enzyme-retting of flax with pectate lyase.

Panasonic has set up a plant in Malaysia to manufacture kenaf fibre boards and export them to Japan. Again in 1987, a Canadian mill produced 13 rolls of kenaf newsprint which were used by four U.S. newspapers to print experimental issues. The lighter the material, the further the car can travel on a single gas or battery charge. The kenaf cubes produced were 3 × 3 cm square with lengths ranging from 3 to 13 cm. According to Miyake and Suzuta (1937), there are more than 129 names for kenaf worldwide. D.E. Textile Research Journal, 72(7) (2002) 618-624. Kenaf fibre was mixed with Polypropylene (PP) in addition of maleic anhydride (MAPP). M.J.J.H.A. A precise understanding of the genetic architecture underlying leaf morphology and bast fibre is critical for improving the fibre yield and quality of climate‐resilient kenaf varieties. 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. The first edition of the book was printed on kenaf paper. There is no fiber treatment for both mats. The use of kenaf is anticipated to offset 300,000 pounds of oil-based resin per year in North America and should reduce the weight of the door bolsters by 25 percent. Parikh, T.A. Composites Part A: Applied Science and Manufacturing, 41(10) (2010) 1329-1335. Due partly to kenaf fibres being naturally whiter than tree pulp, less bleaching is required to create a brighter sheet of paper. 2.1.1 Kenaf fiber. Amel, B. [2] 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. Kenaf fiber/high-density polyethylene/maleic anhydride (MA)-compatibilized composites were melt mixed in a twin-screw extruder and molded using injection molding machine. Obendorf, Chemical and Biological Retting of Kenaf Fibres. Akin, B. Condon, Brian, M. Sohn, J.A. 4). Foulk, R.B. Construction and Building Materials, 25(4) (2011) 1991-(2001). The fibre is then treated with alkaline treatment using three different concentrations of 5wt%, This page was last edited on 14 December 2020, at 01:45. They found that kenaf newsprint[10] made for stronger, brighter and cleaner pages than standard pine paper with less detriment to the environment. The kenaf fibre density was obtained using mathematical equation by dividing the mass by the volume, according to the ASTM D 1895 standard [].Kenaf fibre was put into a container with a known volume ().The weight of the container was weighed and recorded as and the kenaf filled container was weighed and labeled as :. [4] "The Plant List: A Working List of All Plant Species", "Retting Process Of Some Bast Plant Fibres And Its Effect On Fibre Quality: A Review", Information about Kenaf in German language, Kenaf: Taking Root? Other names include Bimli, Ambary, Ambari Hemp, Deccan Hemp, and Bimlipatum Jute. Printing and writing paper made from the fibrous kenaf plant has been offered in the United States since 1992. The MOR of kenaf and market MDF was 44.97 and 40.65 N mm -2, respectively. El-Barbary, Kenaf Bast Fibres—Part I: Hermetical Alkali Digestion. A. Paridah, M Tahir Sudin, R. Anwar, UMK Hussein, S. Ahmed, Effect of fibre extraction methods on some properties of kenaf bast fibre. Today, while the principal farming areas are China and India, Kanaf is also grown in countries including the US, Mexico, and Senegal. Physicothermal properties of the composites were studied at different percentages of compatibilizer contents using various techniques. 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). Effects of kenaf core and bast fibers as dispersing phases on low density fiberboards (engineered wood) B.U. In 1970, kenaf newsprint produced in the International Paper Company's mill in Pine Bluff, Arkansas, was successfully used by six U.S. newspapers. The cell wall is thick (6.3 µm). Kenaf seeds yield an edible vegetable oil. "kenaf." 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. 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 composite made from 100% carbon fibre was served for a comparison purpose. Kenaf fibre (KF) is extracted from the bast of the plant and has been extensively used as a jute-like material in the past. [7] Uses of kenaf fibre include engineered wood; insulation; clothing-grade cloth; soil-less potting mixes; animal bedding; packing material; and material that absorbs oil and liquids. Hibiscus cannabinus is in the genus Hibiscus and is native to southern Asia, though its exact origin is unknown. [6] The individual fibre cells are about 2–6 mm long and slender. [5] Scientific.Net is a registered brand of Trans Tech Publications Ltd The bast constitutes 40% of the plant. [19] E-glass fiber possesses the highest density while Jute having the lowest, whereas Kenaf fibers is in the middle range density. The stems produce two types of fibre: a coarser fibre in the outer layer (bast fibre), and a finer fibre in the core. The fruit is a capsule 2 cm diameter, containing several seeds. J. Shi, S. Q. Barnes, H. M. Horstemeyer, M. Wang, J. Hassan,M. The kenaf composite panel recorded an internal bond strength (IB) value that was slightly low because of the decrease of core region density. 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. [11] The addition of 8% compatibilizer into 8.5 and 17.5 wt% fiber content improved … Kenaf matures in 100 to 200 days. 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. Merriam-Webster, 2002. B. Ghafar, S.A.A. [8] [7] Paper pulp is produced from the whole stem, and therefore contains two types of fibres, from the bast and from the core. 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. [11], As one of the world's important natural fibres, kenaf is covered by the International Year of Natural Fibres 2009. Long slender primary fibers on the outer portion of the stalk characterize bast fiber plants. 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 … This crop was not introduced into southern Europe until the early 1900s. Webster's Third New International Dictionary, Unabridged. The use of kenaf in paper production offers various environmental advantages over producing paper from trees. Industrial Crops and Products, 46 (2013) 117-123. Materials & Design, 58 (2014). [12]. Kenaf is one of the allied fibres of jute and shows similar characteristics. The fineness and morphology of kenaf fibres are the main focus of this paper. Tensile Properties of Kenaf/Unsaturated Polyester Composites Filled with a Montmorillonite Filler Kenaf oil is high in omega polyunsaturated fatty acids (PUFAs). 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. 3.4 Grinded kenaf fibre through plastic crusher 47 3.5 Plastic crusher 47 3.6 300gram of TPE and kenaf mixture 49 3.7 Twin screw extruder 50 3.8 Fixed Length Pelletizer 50 3.9 Pellets arranged into mold 51 3.10 Hot press Mold 52 3.11 Sample of 10%, 20% and 30% of kenaf fibre and TPE mixture for tensile test. Woven kenaf mat is a plain weave while bamboo mat is punched mat. J Ind Microbiol Biotechnol, 40(5) (2013). Woven kenaf hybrid composites of different weave designs of plain and satin and fabric counts of and were manually prepared by a vacuum infusion technique. Kenaf Fiber/Polypropylene Anand R. Sanadi, J.F. A. Elsaid, A. Dawood, M. Seracino, R. Bobko, C. Mechanical properties of kenaf fibre reinforced concrete. Kenaf can be made into various types of environmental mats, such as seeded grass mats for instant lawns and moldable mats for manufactured parts and containers. The bulk density of the KDC was 0.04 g/cm3. Kenaf [etymology: Persian],[2] Hibiscus cannabinus, is a plant in the family Malvaceae also called Deccan hemp and Java jute. W. Jinhua and G.N. China: Hong Ma (red hemp) has been officially changed from "Yang Ma" (foreign hemp) during the Cultural Revolution, 1966-1976. Charles L. Webber III and Venita K. Bledsoe.

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. International Journal of Polymer Science, (2011) 1-8. R. Mahjoub. Kenaf seed oil contains a high percentage of linoleic acid (Omega-6) a polyunsaturated fatty acid (PUFA). It is estimated that growing kenaf on 5,000 acres (20 km²) can produce enough pulp to supply a paper plant having a capacity of 200 tons per day. Despite this, glass fiber showed a dominant value for each property yet extensively applied in the automotive component. [6] Steam was injected into the digester. 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). [17] 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. 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. 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. Properties Kenaf Fiber Glass Fiber Density 1.4 2.5 Strength 284-800 2000-3000 Modulus (GPa) 21-60 70 Elongation at break 1.6 2.5 Table 2 showed the comparative properties of density, strength, modulus and elongation at break between kenaf fiber and glass fiber. Kenaf seed oil is 20.4% of the total seed weight, similar to that of cotton seed. By weighing the empty measuring cup and subsequently filling the cup with cellulose, the bulk density was calculated. The kenaf/ramie blend was fed into a lab-scale carding machine twice to obtain uniform fiber web. The main attraction of the kenaf plant is the bast fibres because of their specific high strength to low … A Morisson Benkshire needle-punching machine was used for mechanically bonding the kenaf/ramie web.

The kenaf fiber was cleaned by cotton cleaner and mixed with the ramie fi-ber in a ratio of 70% kenaf and 30% ramie. [12] Hydrogen peroxide, an environmentally-safe bleaching agent that does not create dioxin, has been used with much success in the bleaching of kenaf. The kenaf yarn has a density … 1. 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. The kenaf seed oil is also used for cosmetics, industrial lubricants and for biofuel production. The bulk density of the fibers used was 1.2 g/cm3. [3] 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. [13] M. Zimniewska, M.
