Wool comes mostly from sheep. It was the first fibre to be spun into yarn and it provides more warmth than other animal fibres. Apart from sheep, wool also comes from the angora goat, yak, llama, alpaca, and even camels. All these animals have a thick coat of hair or fleece, which keeps them warm. Wool is obtained from this fleece.

Shearing is the first step in processing fibre into wool. It is the removal of the fleece of the sheep along with a thin layer of the skin.

The next step is to clean the sheared skin and hair. This is done in big tanks to remove the grease, dust and dirt. This is called scouring.

The fleece is sorted according to its texture and type

Since the fibres are mostly black, brown or white in colour, they can now be dyed in various colours.

Once the dyeing process is complete, the fibres are straightened, combed and rolled into yarn.

The longer fibres are made into wool for sweaters, while the shorter fibres are spun and woven into woollen cloth.

there are six steps by which wool is obtained form sheep. Step 1: shearing The process of removing hair from the body of a sheep is called shearing Step 2: scouring The process of washing the fleece of sheep to remove dust, dirt, sweat and grease etc. is called scouring Step 3: sorting The process of separating the long fine quality fleece from the remaining inferior quality or broken pieces is called sorting. Step 4: combing The process of removing the burrs from the fleece is called combing Step 5: dyeing The natural fleece of sheep is black, brown or white in color. The fibres obtained after combing is dyed in various colors. This is called dyeing. Step 6: spinning The straightened fibres are spun or twisted together to make yarn. The wool yarn is then used to knit woolen fabrics, sweaters etc. This is called spinning.
