Abstract: Intent of the research is surface treatment of the coir fibre for bestowing hydrophobic properties and augmenting its strength for contriving coir products and composites. Sodium hydroxide and acetic acid of varying percentages of 5 to 20 were employed in surface treatments. An increment around 35% for mercerization and 24% for acetylation is discern in tensile strength, cutback of 15% is perceived in flexural rigidity after incorporation of 10% NaOHin mercerization whilst acetylation increases, and a reduction of 20 % in hydrophilicity is surveilled for both treatments compared with control. Fibres picked up for dyeability and check the colour fastness, the outcome stipulate that the treated fibres improve colour fastness towards light. Variables such as scorage, runnage and twist of 2 ply yarn spawn from treated fibres were scrutinized along with control and from scanning electron microscopic studies it’s obvious that even a minimal of 10% addition of NaOH/CH3COOHshows vouchsafe properties that could be employed in production of coir products and composites.
