Preparation of degradable composite material from water hyacinth fiber

Water hyacinth fiber can be applied in various packaging products which is biodegradable and environmentally friendly. The purpose of this study was to develop composite material from water hyacinth fibers by drying method combined with hot press molding. Chitosan and Alkyl Ketene Dimer (AKD) were used as adhesive and sizing substances. In addition, the physical properties were analyzed including tensile strength, oil absorption resistance, swelling ratio, water contact angle, and degradability. The ratio between chitosan, AKD, and water hyacinth fiber was also studied. The increase in the amount of AKD resulted in higher water resistance. The addition of chitosan led to higher tensile strength. The oil absorption resistance tended to increase with increasing amounts of AKD and chitosan. In addition, adding AKD and chitosan resulted in a slower degradation rate.
