Question

Write various steps for processing fibres into wool.

Accepted Answer

The various steps for processing fibres into wool:
Step I: The fleece of the sheep along with a thin layer of skin is removed from its body. This process is called shearing. Machines similar to those used by barbers are used to shave off hair. Usually, hairs are removed during the hot weather. This enables the sheep to survive without their protective coat of hair.

Step II: The sheared skin with hair is thoroughly washed in tanks to remove greases, dust and dirt. This is called scouring. Nowadays, scouring is done by machines.

Step III: After the procedure of scouring, the next step is sorting. In this procedure, washed hairs are sent to various factories. In the factories, separation of different texture of hairs takes place.

Step IV: The small fluffy fibres, called burrs, are picked out from the hair. The fibres are scoured again and dried. This is the wool ready to be drawn into fibres.
Step V: The fibres can be dyed in various colours, as the natural fleece of sheep and goat is black, brown or white.
Step VI: The fibres are straightened, combed, and also rolled into yarn. The longer fibres are made into wool for sweaters and the shorter fibres are spun and woven into woollen cloths.
