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.
