The various steps for processing fibres into wool are :- >> A sheep or yak body has a thick coat of hair called " fleece". * the first step involves shearing. * The process of removing the fleece using special clippers is called shearing. * Shearing is done manually with a razor or with the help of a shearing machine. * Shearing does not hurt the sheep because the uppermost layer of the skin which is remove along with fleece is dead. >> The sheared hair is clean and washed in tanks to remove grease, dust and dirt. This is called scouring. Now- a- days scouring is done machines. >> The cleaned hair are sent to a factory where hair of different textures are separated or sorted. This is called sorting. * Small fluffy fibres called burrs are picked out from the hair. The fibres are scoured again and dried. * Now the wool is ready to drawn into fibres. >> Next, the hair are sent into a 'carding' machine. * it combs the loose wool fibres into a sheet. * This sheet is twisted into a rope or silver. This silver is twisted and stretched into a yarn. * The yarn is wound to form balls of wool. >> Now the wool is ready to use.
