Results indicate that kenaf It has strong ability to hold shape, reduce wrinkle. The carbon footprint left by the cultivation and processing of the fiber is nearly invisible. Kenaf [etymology: Persian], Hibiscus cannabinus, is a plant in the family Malvaceae also called Deccan hemp and Java jute. Advantages and Disadvantages of Ramie Fibers: In the below, I have written about advantages and disadvantages of ramie … The bleached kenaf fiber was then compounded with poly-(lactic acid) (PLA) via a melt blending method. By Vineta Srebrenkoska. It is a durable fiber. There is only one minor disadvantage from eating dietary fiber. It’s processing is as like linen fiber. The highest growth rate may up to 10 cm/day. Get PDF (4 MB) Abstract. Comparation of kenaf fiber composites to structural composites produced by "Eurokompozit"\ud . The Young modulus and tensile strength of unidirectional kenaf fiber is about 2 to 4 GPa and 18 MPa, respectively. Journal of Biomimetics, Biomaterials and Biomedical Engineering Materials Science. 2.3.2 Composition and structure of plant fibers . Kenaf fiber uses in the paper product industry. HISTORY. In order toconvert kenaf fibers into a fiber for valuable textile products, they must be either chemically or bacterially retted. 19. Here, the kenaf fibers were modified using NaOH at different solutions. Kenaf plant is claimed as one of the fast-growing herbaceous plants with the high potential as a fiber material or lignocellulosic material. 27. The mechanical (tensile, flexural and impact) performance of the product was tested. considerations. Disadvantages of Carbon fibre reinforcement polymer (CFRP) Although carbon fiber can be relatively expensive, there are used to make aircraft and spacecraft parts, racing car bodies, golf club shafts, bicycle frames, fishing rods, automobile springs, sailboat masts, and many other components where light weight and high strength are needed. The hybridization of natural fiber with another natural fiber or synthetic fiber will combine the advantages of both constituents and result in superior properties. Kenaf's value per acre of land, moreover, is greater than pine's since its fiber yield (6-10 tons of dry fiber per acre annually) ranges from two to five times higher than pine's. Kenaf, known as Hibiscus cannabimus L., is an herbaceous annual plant that grows in a wide range of weather conditions, growing more than 3 m within 3 months (Nishino et al., 2003). In terms of process, Kenaf as pulp has many advantages as it does not require high energy consumption and also less chemical usage. The flexural strength of hybrid glass/kenaf/glass laminates was 32.5 % higher than non-hybrid glass fiber reinforced composites. THE ENVIRONMENTAL ADVANTAGES OF KENAF PAPER. A random mat of kenaf fiber with the density of 1.4 g/cm 3 was supplied by a local company named Innovative Pultrusion Sdn Bhd. Kenaf Yield Components and Plant Composition .
