Jute is collected from the stem bark of Corchorus capsularis and Corchorus olitorius plants. The stems are cut before flowering and undergo a retting process where they are soaked in water. This softens the fibers and allows them to be separated from the inner woody core. Jute fibers are long, golden yellow in color, and contain high amounts of cellulose. They are used to make cloth, sacks, twine and rope. Hibiscus cannabinus fibers can substitute for jute.

4. • The unbranched stems of the jute plant are cut and formed a bundle before flowering stage
• The jute fibre comes from the stem and ribbon (outer skin) of the jute plant.
• Retting is a microbial process by which the jute plant is immersed in water and the fibre is loosened from the woody core of the
jute plant.
• This process softens the tissues and breaks the hard pectin bond between the bast and jute hurd (inner woody fibre stick) and the
process permits the fibres to be separated.
• At 34ºC this temperature it takes generally 8-12 days for complete retting.
• The retting process consists of bundling jute stems together and immersing them in slow running water.
• In the stripping process, non-fibrous matter is scraped off, leaving the fibres to be pulled out from within the stem and washed in
clear, running water.
• Then they are hung up or spread on thatched roofs to dry.
• After 2-3 days of drying, the fibres are tied into bundles.

7. Uses
 to make cloth for wrapping bales of raw cotton, and to make sacks and coarse cloth
 The fibres are also woven into curtains, chair, coverings and carpets.
 The fibres are used alone or blended with other types of fibres to make twine and rope
Substitutes:
Fibres of Hibiscus cannabinus are used as substitutes for jute fibres.
