density of kenaf fiber

The kenaf fibres were processed through water retting, chemical retting and mechanical extractions. 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 fruit is a capsule 2 cm diameter, containing several seeds. Long slender primary fibers on the outer portion of the stalk characterize bast fiber plants. Composites From Kenaf Fiber and Plasticized Poly(lactic acid) (12th Asian Chemical Congress (12ACC), 23rd – 25th August 2007, Putra World Trade Centre, Kuala Lumpur, Malaysia) 209. The kenaf/ramie blend was fed into a lab-scale carding machine twice to obtain uniform fiber web. By weighing the empty measuring cup and subsequently filling the cup with cellulose, the bulk density was calculated. J. Summerscales, J. Dissanayake, N. P. J. Virk, A. S. Hall, Wayne, A review of bast fibres and their composites. A Morisson Benkshire needle-punching machine was used for mechanically bonding the kenaf/ramie web. Kenaf fibre was mixed with Polypropylene (PP) in addition of maleic anhydride (MAPP). Despite this, glass fiber showed a dominant value for each property yet extensively applied in the automotive component. Physicothermal properties of the composites were studied at different percentages of compatibilizer contents using various techniques. 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. HISTORY. The MOR of kenaf and market MDF was 44.97 and 40.65 N mm -2, respectively. Rozana Mohd Dahan, Ahmad Zafir Romli, Dr. Mohd Rozi Ahmad and Dzaraini Kamarun, https://doi.org/10.4028/www.scientific.net/AMR.1134.103.

The main uses of kenaf fibre have been rope, twine, coarse cloth (similar to that made from jute), and paper. 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. This crop was not introduced into southern Europe until the early 1900s. The stems are 1–2 cm diameter, often but not always branched. S. Kyung Hun, S.K. A. Paridah, M Tahir Sudin, R. Anwar, UMK Hussein, S. Ahmed, Effect of fibre extraction methods on some properties of kenaf bast fibre. The cell wall is thick (6.3 µm). Kenaf were separated from the outer layer and bast fibre and were cut usingcrusher . The kenaf fiber was cleaned by cotton cleaner and mixed with the ramie fi-ber in a ratio of 70% kenaf and 30% ramie. J Ind Microbiol Biotechnol, 40(5) (2013). The addition of 8% compatibilizer into 8.5 and 17.5 wt% fiber content improved … R. Yatim, J. M. Sam, A. R. M. Hashemi, S.

Woven kenaf mat is a plain weave while bamboo mat is punched mat. Fig. Kenaf seeds yield an edible vegetable oil. 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. J. Shi, S. Q. Barnes, H. M. Horstemeyer, M. Wang, J. Hassan,M. The kenaf yarn has a density … Webster's Third New International Dictionary, Unabridged. The density of these materials will determine how light the final product will be and especially important when making sports equipment that involves speed. 1. The kenaf fibers used in this study were ob-tained from National Tobacco Board at Kelantan, Malaysia. Kenaf matures in 100 to 200 days. Ramaswamy, One-step processing and bleaching of mechanically separated kenaf fibres: effects on physical and chemical properties. Kenaf seed oil contains a high percentage of linoleic acid (Omega-6) a polyunsaturated fatty acid (PUFA). ever, due to the lower density of kenaf fibers this ratio was increased. The diameter of kenaf fiber and bamboo fiber are 21.9 µm and 11.6 µm respectively. Amel, B. Construction and Building Materials, 55 (2014) 103-113. The bulk density of the KDC was 0.04 g/cm3. 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. 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. The kenaf fibres were processed through water retting, chemical retting and mechanical extractions. Printing and writing paper made from the fibrous kenaf plant has been offered in the United States since 1992. 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 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. Industrial Crops and Products, 29(2-3) (2009) 301-307. There is no fiber treatment for both mats. 2.1.1 Kenaf fiber. Construction and Building Materials, 25(4) (2011) 1991-(2001).

They produced kenaf pellets over a range of 0.5 to 1.9 cm in diameter (Fig. Alpha-linolenic acid (C18:3) is present in 2 to 4 percent. [2] 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 … Kenaf is one of the allied fibres of jute and shows similar characteristics. Composites Part A: Applied Science and Manufacturing, 41(10) (2010) 1329-1335. 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. Food and Bioproducts Processing, 89(4) (2011) 328-332. Moreover, the combination of the natural fiber and the biodegradable polymer able to reduce the negative impact on human health. [4] B. Ghafar, S.A.A. Abstract. Tensile Properties of Kenaf/Unsaturated Polyester Composites Filled with a Montmorillonite Filler Again in 1987, a Canadian mill produced 13 rolls of kenaf newsprint which were used by four U.S. newspapers to print experimental issues. Kenaf fiber is usually reinforced with synthetic based polymer resin such as polypropylene. "kenaf." Kenaf is one of the allied fibres of jute and shows similar characteristics. 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. Abdul Khalil, Abdul Yusra, AF Ireana Bhat, AH Jawaid, M , Cell wall ultrastructure, anatomy, lignin distribution, and chemical composition of Malaysian cultivated kenaf fibre. 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 :. The areal density of each woven kenaf mat and bamboo mat were 600 g/m 2 and 800 g/m 2 respectively. 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. [9] 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. Panasonic has set up a plant in Malaysia to manufacture kenaf fibre boards and export them to Japan. These textile products are aesthetically pleasing, strong, lightweight, and have an excellent soft feel. [3] The bast constitutes 40% of the plant. The first edition of the book was printed on kenaf paper. According to Miyake and Suzuta (1937), there are more than 129 names for kenaf worldwide. 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. Anyanwu et al-This content was downloaded from IP address 40.77.167.75 on 24/04/2020 at 01:47. Kenaf oil is high in omega polyunsaturated fatty acids (PUFAs). 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. Scientific.Net is a registered brand of Trans Tech Publications Ltd Kenaf Yield Components and Plant Composition . D.V. The ESEM micrographs of A) Untreated kenaf fibre at 1500x magnification, KDC at 3000x magnification B), … Akin, B. Condon, Brian, M. Sohn, J.A. The flowers are 8–15 cm diameter, white, yellow, or purple; when white or yellow, the centre is still dark purple.

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. Hemp is a bast fiber plant similar to Flax, Kenaf, Jute, and Ramie. [7] H.P.S. 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. Industrial Crops and Products, 31(1) (2010) 113-121. The kenaf seed oil is also used for cosmetics, industrial lubricants and for biofuel production. Today, while the principal farming areas are China and India, Kanaf is also grown in countries including the US, Mexico, and Senegal. Kenaf [etymology: Persian],[2] Hibiscus cannabinus, is a plant in the family Malvaceae also called Deccan hemp and Java jute. Industrial Crops and Products, 32(3) (2010) 231-240. Other names include Bimli, Ambary, Ambari Hemp, Deccan Hemp, and Bimlipatum Jute. D.E. The pulp quality is similar to that of hardwood. [7] Paper pulp is produced from the whole stem, and therefore contains two types of fibres, from the bast and from the core. A composite made from 100% carbon fibre was served for a comparison purpose. 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. In 1960, the USDA surveyed more than 500 plants and selected kenaf as the most promising source of tree-free newsprint. Linoleic acid (C18:2) is the dominant PUFA, followed by oleic acid (C18:1). The stems produce two types of fibre: a coarser fibre in the outer layer (bast fibre), and a finer fibre in the core. Industrial Crops and Products, 25(2) (2007) 136-146. Foulk, R.B. [11], As one of the world's important natural fibres, kenaf is covered by the International Year of Natural Fibres 2009. "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? The first implementation of kenaf within a Ford vehicle was in the 2013 Ford Escape. Hibiscus cannabinus is in the genus Hibiscus and is native to southern Asia, though its exact origin is unknown. Kenaf seed oil is 20.4% of the total seed weight, similar to that of cotton seed. 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. They found that kenaf newsprint[10] made for stronger, brighter and cleaner pages than standard pine paper with less detriment to the environment. 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. Effects of kenaf core and bast fibers as dispersing phases on low density fiberboards (engineered wood) B.U. The density of kenaf MDF and market MDF were respectively, 0.73 and 0.72 g cm -3. The physical and mechanical properties of kenaf MDF were better than market MDF. [15] International Journal of Polymer Science, (2011) 1-8. 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). 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. Hunt, D.F. Rigsby, Optimization for enzyme-retting of flax with pectate lyase. 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. The name also applies to the fibre obtained from this plant. 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. It was probably used first in Asia. [11] The fibres in kenaf are found in the bast (bark) and core (wood). Kenaf [etymology: Persian], Hibiscus cannabinus, is a plant in the family Malvaceae also called Deccan hemp and Java jute. Blanchard, F. J. Screen, M. Warnock, D.H. Muller, D.D. However, recent studies tend to concern towards the environmental issues which kenaf fiber act as an alternative natural fiber competitor. [17] R. Mahjoub. [12] Obendorf, Chemical and Biological Retting of Kenaf Fibres. 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. Hemp is also one of the bast fibers known to ancient Asians, long before the birth of Christ. The fineness and morphology of kenaf fibres are the main focus of this paper. N.G. The main attraction of the kenaf plant is the bast fibres because of their specific high strength to low … 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. [19] 3) Pulping was conducted in a 350-mL stainless steel air tight container, using a stationary steam digester. The bulk density of the KDC was 0.04 g/cm 3. [18] Paridah, Maznah , Effect of kenaf seed oil from different ways of extraction towards ovarian cancer cells. 1. In order to modify and possibly improve the adhesion between the fibers and the matrix, the fibers … 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. The bulk density of the fibers used was 1.2 g/cm3. 4). Dodd, L.L. Cellulose, 21(1) (2014) 569-579. [12]. 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. L.S. M. Paiva, M. Ammar, I. Campos, A. Cheikh, R. Cunha, A., Alfa fibres: Mechanical, morphological and interfacial characterization. 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. E-glass fiber possesses the highest density while Jute having the lowest, whereas Kenaf fibers is in the middle range density. The chemical retting method resulted in smoother fibre surface when examined using Field Emission Scanning Electron Microscopy under different magnifications. Oksman, Preparation of cellulose nanofibres with hydrophobic surface characteristics. Y.A. The kenaf cubes produced were 3 × 3 cm square with lengths ranging from 3 to 13 cm. The lighter the material, the further the car can travel on a single gas or battery charge. A. Elsaid, A. Dawood, M. Seracino, R. Bobko, C. Mechanical properties of kenaf fibre reinforced concrete. Sawhney, E.J. 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 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. Materials & Design, 58 (2014). The fineness and morphology of kenaf fibres are the main focus of this paper. [16] China: Hong Ma (red hemp) has been officially changed from "Yang Ma" (foreign hemp) during the Cultural Revolution, 1966-1976. 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. The use of kenaf in paper production offers various environmental advantages over producing paper from trees. Kenaf fiber/high-density polyethylene/maleic anhydride (MA)-compatibilized composites were melt mixed in a twin-screw extruder and molded using injection molding machine. Kenaf Fiber/Polypropylene Anand R. Sanadi, J.F. The bast fibres are used to make ropes. as a composite. The kenaf composite panel recorded an internal bond strength (IB) value that was slightly low because of the decrease of core region density. [5] Industrial Crops and Products, 46 (2013) 117-123. W. Jinhua and G.N. M.J.J.H.A. Chan, K. W. Tahir, M.I. Due partly to kenaf fibres being naturally whiter than tree pulp, less bleaching is required to create a brighter sheet of paper. Calamari, A.P.S. 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. 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). [6] The individual fibre cells are about 2–6 mm long and slender. [13] The effects of carbon fibre hybridisation on the thermal properties of woven kenaf-reinforced epoxy composites were studied. Part 1 – Fibres as reinforcements. [8] The BMW i3 uses kenaf in the black surrounds.[9]. Yaza, L. S. Foo, J. [1] Steam was injected into the digester. [citation needed] Composites Science and Technology, 67(6) (2007) 1132-1138. [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. [8] Textile Research Journal, 72(7) (2002) 618-624. "Crude fibre" separated from the bast is multi-cellular, consisting of several individual cells stuck together. 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. Fig. The ash content is removed by sieving and washing the fibre. J.
