Question

Write various steps for processing fibres into wool.

Answer 1

Various steps for processing fibres into wool are:

1. Shearing: The removal of wool or fleece from a sheep or other wool yielding animal is called shearing. It can be done manually with a large razor or with a shearing machine.
2. Scouring: The sheared hair is moved through tubs filled with soapy water to remove dust, dirt and grease. This is known as scouring. It is then passed through a series of rollers and dryers.
3. Sorting: Sorting consists of separating the hair of different textures.
4. Removing burr: Burrs are soft fluffy fibres in wool. These are removed manually.
5. Carding: During the process of carding, the clean selected wool fibres are passed through rollers that have thin wired teeth The teeth untangle the fibres and arrange them into a flat sheet called a web. The web is then formed into narrow untwisted fibres known as slivers.
6. Dyeing: The natural hair of sheep is white, brown or black. It is dyed in different colours.
7. Spinning: The fibres are straightened, combed and rolled into yam. The process of making yarn from fibres is called spinning.
