Theory:

In previous lessons, we learned to make fabric by arranging the yarns together. Now, let us explore how these yarns are made?
In simple terms, fabrics made up of yarns, and yarns further made up of fibres.
Where do these fibres come from?
We get fibers from natural sources such as cotton, jute, silk, and wool, that obtained from plants and animals. These are called natural fibres.

Cotton
From plants
Jute
From plants
Wool
Obtained from the fleece of sheep or goat
Silk
Drawn from the cocoon of a silkworm
Hair
Obtained from the rabbit

For thousands of years, natural fibre was the only available source for making fabric. But in this modern world, using science and technology, we make fibres artificially. These are called Synthetic fibres.
 
Some examples of synthetic fibres:
 
1. Polyester
 
2. Nylon
 
3. Acrylic
