Cotton fibre:
The cotton plant bears fruits about the size of a lemon, calledcotton bolls. The bolls are fibrous and full of seeds. When they are ripe, they burst open and the fiber is collected by hand from the ripe cotton bolls. This process is calledpicking. Next, the cottonfibresare separated from the seeds by combing them by a process known asginning. Earlier, ginning was done by hand, but nowadays, machines have been invented to do that for us.
Jute fibre:
The jute plant is generallyharvestedwhen it is in theflowering stage. The stems of jute plants are soaked in water for a few days until they startrotting. Then thefibresare separated by hand from the rotting stems.
Climatic conditions:
For cotton plants, the ideal conditions are warm climates and black soil, like in Gujarat.
For jute plants, it is necessary to have high temperatures and a lot of rainfall, like in Assam.
