The jute fiber comes from the stem and ribbon (outer skin) of the jute plant. The fibers are first extracted by retting. The retting process consists of bundling jute stems together and immersing them in slow running water.
Jute is obtained from the plants Corchorus olitorius and Corchorus capsularis. These plants are native to the Indian subcontinent and are grown throughout the year. The jute fibres are mainly concentrated near the woody, central parts of the stalk. They are composed of cellulose and lignin.
