As any
physics student knows,
elasticity is the property
of a solid material to
return to its original
shape and size after the
forces deforming it have
been removed.
Sheep wool
has the highest elasticity
of any known natural
fiber, which is one of its
most striking properties.
It is said that “wool
fiber is so resilient and
elastic that it can be
bent 30,000 times and
still return to its normal
shape. Every wool fiber
has a natural elasticity
and crimp
that allows it to be
stretched up to one-third
its normal
length.”(http://www.sheep101.info/warmwool.html)
The fibers do not sag,
crumple or wrinkle, as
they always conform to
their original state. This
is what makes wool
clothing such a great
investment, as it is
incredibly long lasting.
