Processing of fibres into wool
Processing of fibres into wool
Processing of fibres into wool: The different processes involved in wool production:
1. Shearing: the fleece of the sheep along with thin layer of skin is removed from the body. This process is called shearing. The hair of sheep are shaved off by using a shaving machine similar to those used by barbers. Shearing does not hurt the sheep because the uppermost layer of skin of sheep is dead. The shearing of sheep is done in hot weather of summers so that sheep may survive without their protective coat of hair. The fleece of sheep provides woolen fibres.
2. Scouring: the fleece of sheep contains dust, dirt, dried sweat and grease etc. So, the sheared hairs of sheep are thoroughly cleaned by washing with soap and lot o water in tanks. This process of washing of shared hair is called scouring. It makes the fleece of sheep clean
3. Sorting: the process of separating the fleece of a sheep into sections according to the quality of woolen fibres (such as fine, coarse, long, short etc) is called sorting. In sorting, the hairy skin is sent to a factory where hair of different textures are separated or sorted. The same quality wool obtained is then mixed together.
4. Picking of Burrs: The small fluffy are then picked out from the hair. These fluffy fibres are called burrs. These burs can also be seen in sweaters. The fibres are again scoured and died. The small fluffy fibres called burrs are picked out from the hair (burrs are soft, fluffy fibres in wool)
5. The natural fleece or hair of sheep is white, brown or black in colour. The white woolen fibres obtained by sorting can be dyed in different colours.
6. The fibres are straightened, combed and rolled into yarn. The long woolen fibres are spun or twisted into thick yarn called wool which is used for knitting sweaters etc. The short woolen fibres are spun into fine yarns and then woven on a loom to make woolen clothes.
