A

Jute is a fibre obtained from stem of jute plant. Jute is harvested during flowering stage. The stems are cut off close to the ground and are left to dry for sometime. Dried stems are then tied into bundles and soaked in water for about 20 days. This process is called retting. It softens the tissue and permits the fibres to be separated.
