Production
and Processing:-
The urena
plant is a perennial (means grown once in year), with stalks that grow to a
height of 3m (10 ft).
After harvesting, the stalks are retted like
jute in ponds or slow streams for 1 - 2 weeks. The fibres are stripped from the
retted stalks by hand and washed to remove unwanted material.
Structure
and Properties:-
Urena has an
attractive handle and appearance. It is near-white when carefully retted, and
is soft to the touch. It has a natural lustre.
The fiber
has strength similar to that of jute.
Strands of
commercial urena are often 1.2m (4 ft) long.
Individual
cells of urena are generally less than
2.6mm (1/10th in) long. The lumen as in the kenaf cell is usually
irreragular.
