Various steps for processing fibres into wool are as follows: The first step is to remove the fleece of the sheep along with a thin layer of skin. This process is called shearing. The next step is scouring, in this step, the sheared hair is washed thoroughly to remove grease, dust and dirt. The next step is sorting, in which different textures of hair are separated or sorted. The fourth step is separating burrs, burrs are small fluffy fibres which are picked out from the hair. Dyeing is the fifth step in which the fibres are dyed in various colours, as the original colours of fleece are usually black, white or brown.
