Optimum Conditions for Mercerization Rattan Palm Fibre

Rattan palm fiber was treated with a solution of 2wt%-10wt% NaOH for 30mins-150mins and the tensile strength, toughness, modulus of elasticity, yield strength and ductility were studied using response surface methodology. The results reveal that mercerization of rattan palm fiber increases the modulus of elasticity and yield strength about three times, tensile strength and toughness were increased more than twenty five. The optimum concentration and time for most of the mechanical properties was a NaOH concentration of 4wt% and treatment time of 120mins. NaOH concentration has the most significant effect on fiber mechanical properties among the two properties studied, though there is significant interaction between the two variables. The optimum NaOH concentration and time from this study is recommended for mercerization of rattan palm fiber prior to use in composite manufacture.
