Complete step by step answer:
Wool is a natural animal fibre prepared from the fur of sheep, goats, etc. The fur present in sheep bodies will help the sheep to protect them from cold and also it makes them feel warm. Sheep has a thick fur-like hair structure and this hair helps to trap the air that is present in the atmosphere. This trapped air helps to keep the body of sheep warm and protective during cold conditions.
Generally, sheep have two kinds of fibres. One is from their beard and the other is from their skin. Among the two, skin hair is mainly used to produce wool. The production of wool from sheep’s skin fibre involves the following steps. They are shearing, scouring, aborting, dyeing, straightening, rolling, and combing.
In the shearing process, the fleece of sheep will be removed. And the removal of fleece, it undergoes washing to remove dust and Greece. This process is called scouring. After scouring, low-quality and high-quality fibres are differentiated and this process is called sorting.
