Description: Recent studies on Typha spp. commonly known as cattail have revealed its prospect of being used as a new source of natural fibre. An investigation was carried out to examine the influence of extraction time and temperature on physical and mechanical properties of cattail fibers for composite applications. The fibres were obtained from the leaves of Typha latifolia L. using a fixed concentration (10%, w/v) of NaOH with four levels of temperature (70, 80, 90 and 95?C) and five levels of time (4, 6, 8, 10 and 12 h). By changing the treatment time, and temperature, the fiber yield (%) varied from 52.32 to 9.30% with a diameter varied from 467.21 to 61.60 ?m. Similarly, breaking load, extension at break (%), and breaking stress of the fibers varied from 5.21 to 0.08 N, from 6.81 to 0.14%, and from 121.97 to 6.40 MPa respectively. The two-way factorial ANOVA revealed that properties such as fibre yield, breaking load, and extension at break were influenced significantly by time, temperature, and their interaction. Fibre diameter was influenced significantly by both time and temperature, and for the breaking stress of fibres the effects of temperature and the interaction between time and temperature were found significant. The Desirability Function Analysis (DFA) determined the optimum extraction time and temperature for fibres that can be used for composite reinforcement as 6 Hrs. and 80? C.
