In this section, we will give you an introduction about wool and detailed steps for its extraction
Wool is one of the most important animal fibers which are used as a textile fibre. Woolen fabric holds a greater market than other textile fabrics. Wools are mainly obtained from animals like sheep, angora goats, yak, Alpaca, camel etc. Wools are generally obtained from sheep in India, Ladakh and Tibet wool is obtained from Yak. In some regions of Jammu and Kashmir wools are obtained from angora goats. Various processes are used for the extraction wool from sheep. These processes are given as follows:
Steps for Extraction of Wool from Sheep:
The following processes are used in extraction of wool from sheep:
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.
Step 2: Scouring: After removing the fleece from the body of sheep, it is washed to separate dirt and grease from the fleece.
Step 3: Sorting: 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.
Step 4: After sorting the fleece, a fiber that is called burr is picked out from the hair.
Step 5: Dying: After sorting and separating burrs, they are dyed in the required colour.
Step 6: Spinning: After dyeing wools, the fibres are then combed, straightened and rolled into yarns.
