| dc.description.abstract | Recent studies on Typha spp. commonly-known as cattail has revealed its prospect of being used as a new source of natural fiber. An investigation was carried out to examine the influence of extraction time, temperature, and concentration of alkali on the physical and mechanical properties of cattail fibers for bio-composite applications. The fibres were obtained from the leaves of Typha latifolia L. using 3 levels of concentration (4, 7, 10%, w/v) of NaOH with 4 levels of temperature (70, 80, 90, and 95° C), and 5 levels of time (4, 6, 8, 10, and 12 h.) in a 3*4*5 factorial experimental design. The three-way factorial ANOVA revealed that yield (%), diameter, tensile strength, elongation at break (%), and moisture regain (%) of fibres were influenced significantly (P < 0.05) by time, temperature, concentration and the interaction between temperature and concentration. For modulus of elasticity of fibres, the effects of time, temperature, the interaction between time and concentration, and the interaction between temperature and concentration were found significant (P < 0.05). After analyzing the estimated treatment means of response variables, it was determined that the mechanical properties of cattail fibres have similarities with sisal, and coir fibres and can be used in automobile and packaging applications. The extraction parameters were optimized using desirability function analysis (DFA) which determined the optimum extraction time, temperature and concentration of NaOH as 10 h., 90º C, and 7% for automobile applications and 6 h., 90º C, and 7% for packaging applications. | en_US |
