SOME PLANT FIBERS

Cotton

  • The fruits of the cotton plant (cotton

bolls) burst open and the seeds

covered with cotton fibres can be

seen. From these bolls, cotton is

usually picked by hand.

Fibres are then separated from the seeds by combing. This process is called

ginning of cotton.

SPINNING COTTON YARN

  • The process of making yarn from

fibres is called spinning. In this

process, fibres from a mass of cotton

wool are drawn out and twisted.

This brings the fibres together to form

a yarn.

​

  • A simple device used for spinning is

charkha.

Jute

  • Jute fibre is obtained from the stem of the jute plant.
  • The stems of the harvested plants

are immersed in water for a few

days. The stems rot and fibres are

separated by hand.

​

​

​

​

​

​

​

​
