Abstract
The effect of temperature and time duration of degumming process on tensile properties of Pandanus Tectorius fibers has just been studied. While degumming temperature and soaking time for alkali treatment were kept constant at 80 °C and 2 hours, respectively, degumming time was varied at 1, 2, 3 and 4 hours, and sodium hydroxide solution content was varied at 2.5 and 5 wt%. A bundle of fiber was placed in an O-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 showed that tensile strength, tensile failure strain and elastic modulus increase with the increase of degumming time up to 3 hours, then decrease for 4 hours degumming time. The highest values were found being 614.5 MPa, 0.11 mm/mm and 1.07 GPa, respectively.
