ANSWER:
Wool obtained from the fleece of sheep, yak, goat etc. are straightened, combed and rolled into yarn.
EXPLANATION:
Wool fibers are obtained from sheep, goat, yak and other animals. Wool obtained from these are made into clothes to protect us from cold as they are warm and cozy.
This undergoes a long procedure which includes shearing (removing hairs of sheep from its body) of wool, scouring (the hair are washed to remove dirt and filth), sorting (they are sent to industries for further process).
Then, small fibres or burrs are separated in industries and are again scoured and dried to make the wool fibres. They were dyed with different colours to make them look fresh and good. These fibres, free from burrs, are 'straightened', 'combed' and 'rolled' into yarn.
