Pandanus Odorifer (PO) fibre species were treated with varied concentrations (2 -20%) NaOH at room temperature for 1 h and physical properties were evaluated. Chemical composition of the treated fibres showed that hemicellulose was removed to a varied extent by mercerization. Tensile strength of the treated fibres, their moisture content, surface morphology (by Scanning electron microscope), crystallinity index by XRD analysis and thermal degradation (TGA) were analysed. The alkali treated fibres between 2 to 15% showed all round improvement in the properties as compared to with those of untreated raw fibres.
