The effect of temperature and time duration of degumming process on tensile properties of Pandanus Tectorius fibers has just been studied. Whilst degumming temperature and soaking time for alkali treatment were kept constant at 80 degree C and 2 hours, respectively, degumming time was varied at 1, 2, 3 and 4 hours, and sodium hydroxide solution content were varied at 2.5 and 5 wt percent. A bundle of fiber was placed in an O dashed shape cardboard holder for being tensile tested until fracture occurred. Cross sectional areas and fracture modes of representative fibers were captured under optical microscope. Whilst the cross section image areas were then measured by means of an open source software, the imageJ, the fracture images were closely evaluated to determine their respective fracture modes. The result shows that, except for epsilon at 3 hours soaking time and 5 wt percent alkali content, sigma, epsilon and E increase with the increase of degumming time up to 3 hours, then decrease for 4 hours degumming time. The highest sigma, and E were found being 684.31 MPa, 1074.21 MPa, respectively. The highest epsilon was found being 0.140 mm/mm at 4 hours degumming time and 5 wt pecent alkali content.
