The woolly coat which is sheared from a sheep is called the fleece. It is divided up into different areas such as the back neck and shoulder. The fibres in each area are slightly different.
The fleece is pulled apart and the wool from the different areas is separated. The thinnest fibres are used to make yarns for knitwear while the thickest fibres are used to make carpets.
Some other animals also provide us with wool. They are the angora goat which provides us with a wool, called mohair, which is used for making sweaters and suits; the Kashmir goat which provides us with wool called cashmere that is used for making sweaters and coats; the angora rabbit which provides us with wool for knitted clothes; the llama and alpaca which provide us with wool for making dresses, suits and coats, and the camel which provides us with wool to make coats.
