Fibre to Fabric

 

Synopsis

 

  • The thin strands of thread which are used to make yarns are called fibres.

 

  • Yarn is made by twisting the fibres.

 

  • Fibres are of two types - natural and synthetic.

 

  • Natural fibres are obtained either from plants or animals. e.g., cotton, jute, coconut, flax, silk, wool, etc.

 

  • Synthetic fibres are man-made fibres, which are made by using chemicals. e.g., polyester, acrylic, nylon, etc.

 

  • Separating seeds from cotton bolls is called ginning.

 

  • Yarn is spun from cotton fibre using takli or charkha.

 

  • Process of spinning yarn into a fabric is called weaving.

 

  • Jute fibre is made by immersing jute stem in water for a few days.

 

  • Woollen fabric is made by knitting. It is the criss-cross laying of yarns tightly using weaving machines or knitting rods. For example, a sweater is made of a fabric (wool) made of a single yarn (thread).

 

  • Woollen fibres are obtained from the fleece or fur of animals. Silk fibres are obtained from cocoons of silkworms.

 

  • Coconut fibre is obtained from the outer covering of the coconut fruit (coconut husk).

 

  • In ancient times people used leaves, animal skins and furs to cover themselves.

 

  • Vines, animal fleece or hair are also twisted together into long strands and were woven into fabrics.
