Nowadays natural fiber and polymer matrix are being extensively used as alternatives in producing furniture like ceiling, floor and etc. to fulfill society demand instead of environmental friendly and saving cost. The objective of this study is to investigate the effects of maleic anhydride grafted polypropylene (MAPP) as a coupling agent for reinforcement between kenaf fiber (KF) and polypropylene (PP). The ratio of MAPP between 3% and 5% was observed to determine which composition ratio is better. The tensile strength for both 30% KF and 40% KF was treated through the alkali treatment process with 5% sodium hydroxide (NaOH). Kenaf fiber reinforced polypropylene (PP/KF) composites were melt blended and then used hydraulic molding test press machine for characterization to observe their tensile strengths by measuring their threshold. Tensile test was carried out to determine the tensile stresses of the composite at the best composition ratio of kenaf fiber that are 30% KF and 40% KF instead of MAPP ratio. The result shows 40% KF (5% MAPP) lead to better tensile performance compared to 40% KF (3% MAPP), 30% KF (5% MAPP) and 30% KF (3% MAPP). Meanwhile, Scanning electron microscopy (SEM) is used to observe the morphological comparison between untreated KF and treated KF as well as PP/KF. The good interfacial bonding between KF and PP was 5% MAPP rather than 3% MAPP due to the optimum strength received. Overall 5% MAPP with 40% PP/KF had shown the best result compared to others with the estimated tensile strength value of 21.38 MPa.

“…The results revealed that the kenaf fiber offered great strengths to their bio-composites. Based on previous studies, the properties of natural fiber enhanced polypropylene bio-composites were primarily affected by their mechanical properties [17,[22][23]. Many studies into the mechanical, physical, and thermal properties of rice husk and kenaf fiber reinforced polypropylene bio-composites and how this strengthening affects bio-composites have been undertaken as discussed in the accompanying sections.…”

In the previous decades, manufactured filaments, for example, glass or carbon strands have been utilized to strengthen composites of polymer. Be that as it may, with the developing worldwide ecological concerns, moderate biodegradability is their drawback [6]. In this way, researchers are finding other conceivable ways to deal with enhance polymeric composites biodegradability. Natural fiber bio-composites have many advantages, including low costs, sustainability, renewability, good formability, good thermal insulation, eco-friendly, lightweight, processability,

“…Kenaf fibres also offer advantages as composites, being lightweight and environmentally friendly [6]. Conventionally, kenaf is used as a cordage crop to produce twine, rope, carpet backing, burlap and sackcloth [7]. Kenaf's bast fibre is responsible for applications such as nonwoven fabric and reinforced composite materials for automotive, packaging, and aerospace.…”

Controlling sliver evenness is very important since this parameter can affect the quality of the yarn produced. In kenaf sliver production, kenaf fibres alone could not form a good sliver. Thus, fibres such as polyester are needed to blend with kenaf to improve fibre cohesiveness and form a better sliver. The aim of this study is to identify the optimum ratio of kenaf that can be used for sliver production. The heart of the process for the production of kenaf/polyester slivers is carding. The weight percentage of kenaf used for the kenaf/polyester sliver production was 50%, 60% and 70%. After sliver formation, the waste percentage, diameter and size were determined. The sliver images were analysed under video analyser and captured by digital SLR camera to observe the fibre blending. The research showed that lower percentage of kenaf offered better waste percentage and sliver diameter. Whereas, sliver size showed some decrement with an increment of kenaf fibre percentage. The presence of polyester in the production of kenaf/polyester sliver seems to play an important role to bind the kenaf fibres together.
