Steps given below are followed to obtain wool from sheep or other wool-bearing animals:

Step 1: Shearing

The fleece (hair) of sheep is shaved off . In olden days this was done using a pair of metal blades. But nowadays machine is used to cut off the fleece. This is similar to the shaving of beard or hair. This process is called shearing. Shearing is done generally in summer so that sheep could get new hair by winter to get protection against cold.
 

Step 2: Scouring
Fleece, after shearing, is washed properly to remove dirt and grease. The washing of fleece after shearing is called scouring.
Step 3: Sorting
After scouring, fleece is sorted according to texture. This process is called sorting.
Step 4: Picking
After sorting, fluffy fibres called burr are picked out from hair. Burr is the fibre that gives wool.
Step 5: Dying
After sorting and picking out of burrs, these are dyed in desired colours.
Step 6: Spinning
The fibres are then straightened, combed and rolled into yarns.
