Question

How is a wool fibre obtained from the sheared wool?

Accepted Answer

Wool is obtained from the sheep by a long process which involves the following steps: Shearing, Scouring, Sorting, Dyeing, Combing and Spinning.

Shearing:- The process of removing hair (or cutting off hair) from the body of a sheep in the form of fleece is called shearing.

Scouring:- The process of washing the fleece (cut hair of sheep) that removes dust, dirt, dried sweat and grease is called scouring. Scouring makes the fleece of sheep clean.

Sorting:- The process of separating the fleece of a sheep into sections according to the quality of woollen fibres (such as fine, coarse, long, short, etc.) is called sorting.

Dyeing:- The natural fleece or hair of sheep (or goats) is white, brown or black in colour. The white woollen fibres obtained by sorting can be dyed in different colours.

Combing:- Combing is a method to prepare woollen fibres for spinning the yarn. This is done by using combs having metal teeth. The process of combing straightens the entangled woollen fibres and also removes the small fluffy fibres (called ‘burrs’) which may be caught in them.

Spinning:- The long woollen fibres are spun (or twisted) into thick yarn called wool (which is used for knitting sweaters, etc.). The short woollen fibres are spun into fine yarn and then woven on a loom to make woollen cloth (like shawls, etc.).
