Question

Describe briefly, how wool is obtained from sheep and processed to make woollen yarn.

Accepted Answer

Wool is obtained from the sheep by a long process which involves the following steps:

Shearing: The process of removing the hair of a sheep with a thin layer of skin is known as shearing.

Scouring: The process of washing sheared fleece to remove dust, dirt, dried sweat, and grease is called scouring. The scoured fleece is then dried.

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 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.

Spinning: The long woollen fibres are spun into thick yarn called 'wool'. The short woollen fibres are spun into fine yarn and then woven on a loom to make woollen cloth.
