Some fibres are obtained from plants and some from animals. Fibres obtained from animals are silk and wool. Let us understand what type of fibres are got from which animals along with the process of extraction.

• Silk – These fibres are got from cocoons of a silk moth. How? It is obtained from a process called sericulture. When a female silkworm lays eggs and then, it hatches to form silkworms or caterpillars.
• Wool is obtained from wool yielding animals such as yak, goat, sheep, etc. The steps involved are sheering, scouring, sorting and rolling. Please refer Fibre to Fabric Class 7 Notes for more revision notes.
