2. WOOL Wool is a natural animal fibre obtained from sheep (also called a fleece). The hair of sheep has many unique properties that make it well suited to textile production. Wool is used in a variety of textiles and can be found woven or knitted. Wool is favoured for textile production because it is easy to work with and dye very well.

3. PROCESSES INVOLVED IN WOOL PRODUCTION

4. STEP 1: SHEARING In this process, fleece of the sheep is removed along with a thin layer of skin. Nowadays it is done by machines which are used by barbers to shave off hair. Shaving off the hair happens in the hot weather so that sheep can live without their protective coating.

5. STEP 2: SCOURING After removing the fleece from the body of sheep, it is washed to separate dirt and grease from the fleece.

6. STEP 3: GRADING After the process of scouring, fleece is separated according to their texture. Hair of similar texture are kept at one side and the another type of texture in the other.

7. STEP 4: DYEING In the fourth step, the fibres are dyed in desired colours.

8. STEP 5: CARDING In this step, the dyed fibres are passed through metallic teeth to strengthen them.

9. STEP 6: SPINNING In this process, the fibres are then combed, straightened and rolled into yarns. The rolled fibres are then weighed and packed.

10. STEP 7: WEAVING For large scale production of woollen cloths, weaving is done by machines at woollen mills .
