Observations:
The physical properties and residual sericin content of the
cocoon filament from Daba tasar (Antheraea mylitta D), Oak tasar (Antheraea
proylei J) and Bivoltine mulberry (Bombyx mori L) varieties were
evaluated in relation to its position in different layers of the cocoon.
1) A decrease in
filament denier from the outer to the innermost layers was observed in all the
varieties taken for the study.
2) Although the
average tenacity was found to increase in Bivoltine mulberry cocoons from the
outer to the innermost layers, no such specific trend was observed for Daba tasar
cocoons. For Oak tasar cocoons, it showed a marginal rise.
3) The initial
modulus remains constant for Daba tasar and rises marginally for Oak tasar, but
shows a definite increasing trend for the Bivoltine mulberry variety.
4) The breaking
extension remains constant for Daba tasar, decreases for Oak tasar but shows an
initial rise followed by a fall for mulberry cocoons.
5) Residual sericin
shows a tendency to decrease up to the fourth layer from the outermost layer
for Bivoltine mulberry cocoons. Thereafter it remains unchanged. Daba and Oak
tasar cocoons show a marginal decrease from the outer to the inner layer.
