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.
