Physicothermal properties of the composites were studied at different percentages of compatibilizer contents using various techniques. Parikh, T.A. The stems are 1–2 cm diameter, often but not always branched. Kenaf fiber/high-density polyethylene/maleic anhydride (MA)-compatibilized composites were melt mixed in a twin-screw extruder and molded using injection molding machine. Hemp is a bast fiber plant similar to Flax, Kenaf, Jute, and Ramie. J Ind Microbiol Biotechnol, 40(5) (2013). Hemp is also one of the bast fibers known to ancient Asians, long before the birth of Christ. 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. [7] Paper pulp is produced from the whole stem, and therefore contains two types of fibres, from the bast and from the core. The chemical retting method resulted in smoother fibre surface when examined using Field Emission Scanning Electron Microscopy under different magnifications. 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. Hydrogen peroxide, an environmentally-safe bleaching agent that does not create dioxin, has been used with much success in the bleaching of kenaf. Abdul Khalil, Abdul Yusra, AF Ireana Bhat, AH Jawaid, M , Cell wall ultrastructure, anatomy, lignin distribution, and chemical composition of Malaysian cultivated kenaf fibre. 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. Textile Research Journal, 76(10) (2006) 751-756. [16] The bulk density of the KDC was 0.04 g/cm3. 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 areal density of each woven kenaf mat and bamboo mat were 600 g/m 2 and 800 g/m 2 respectively. Rigsby, Optimization for enzyme-retting of flax with pectate lyase. A. Paridah, M Tahir Sudin, R. Anwar, UMK Hussein, S. Ahmed, Effect of fibre extraction methods on some properties of kenaf bast fibre. Steam was injected into the digester. 3) Pulping was conducted in a 350-mL stainless steel air tight container, using a stationary steam digester. ever, due to the lower density of kenaf fibers this ratio was increased. It was probably used first in Asia. Construction and Building Materials, 55 (2014) 103-113. Tensile Properties of Kenaf/Unsaturated Polyester Composites Filled with a Montmorillonite Filler The fineness and morphology of kenaf fibres are the main focus of this paper. Kenaf were separated from the outer layer and bast fibre and were cut usingcrusher . Chan, K. W. Tahir, M.I. S. Kyung Hun, S.K. The bulk density of the KDC was 0.04 g/cm 3. The bast constitutes 40% of the plant. Part 1 – Fibres as reinforcements. [8] The BMW i3 uses kenaf in the black surrounds.[9]. The kenaf/ramie blend was fed into a lab-scale carding machine twice to obtain uniform fiber web. 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. [4] The main attraction of the kenaf plant is the bast fibres because of their specific high strength to low … The kenaf cubes produced were 3 × 3 cm square with lengths ranging from 3 to 13 cm. 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 flowers are 8–15 cm diameter, white, yellow, or purple; when white or yellow, the centre is still dark purple. M.J.J.H.A. Kenaf matures in 100 to 200 days. In 1960, the USDA surveyed more than 500 plants and selected kenaf as the most promising source of tree-free newsprint. They produced kenaf pellets over a range of 0.5 to 1.9 cm in diameter (Fig. The MOR of kenaf and market MDF was 44.97 and 40.65 N mm -2, respectively. Kenaf [etymology: Persian],[2] Hibiscus cannabinus, is a plant in the family Malvaceae also called Deccan hemp and Java jute. Woven kenaf mat is a plain weave while bamboo mat is punched mat. 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. Zimniewska, M. Wladyka-Przybylak, and J. Mankowski, Cellulosic bast fibres, their structure and properties suitable for composite applications, in Cellulose Fibres: Bio-and Nano-Polymer Composites (2011) 97-119. [7] Paridah, Maznah , Effect of kenaf seed oil from different ways of extraction towards ovarian cancer cells. This page was last edited on 14 December 2020, at 01:45. The main uses of kenaf fibre have been rope, twine, coarse cloth (similar to that made from jute), and paper. Effects of kenaf core and bast fibers as dispersing phases on low density fiberboards (engineered wood) B.U. "kenaf." Screen, M. Warnock, D.H. Muller, D.D. The physical and mechanical properties of kenaf MDF were better than market MDF. Kenaf Yield Components and Plant Composition . According to Miyake and Suzuta (1937), there are more than 129 names for kenaf worldwide. [12] Hibiscus cannabinus is in the genus Hibiscus and is native to southern Asia, though its exact origin is unknown. 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 effects of carbon fibre hybridisation on the thermal properties of woven kenaf-reinforced epoxy composites were studied. The diameter of kenaf fiber and bamboo fiber are 21.9 µm and 11.6 µm respectively. [17] 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. Density g/cm3 1: 1.4: Tensile Strength, MPa: 283- 800: Modulus, GPa: 21-60: Specific (E/d) — Elongation at failure, % 1.6: Moisture absorption, % 18: Processing of Kenaf Fiber: Kenaf could be blended with cotton and made into yarn & woven into fabrics. Webster's Third New International Dictionary, Unabridged. Kenaf seeds yield an edible vegetable oil. 1995 article by Brooke Wurst, https://en.wikipedia.org/w/index.php?title=Kenaf&oldid=994089024, Articles with unsourced statements from November 2016, Articles with unsourced statements from June 2015, Articles with unsourced statements from January 2010, Articles with unsourced statements from April 2008, Creative Commons Attribution-ShareAlike License, Brazilian Portuguese: papoula-de-são-francisco, cânhamo-brasileiro, quenafe. The stems produce two types of fibre: a coarser fibre in the outer layer (bast fibre), and a finer fibre in the core.
