Class 7 Science Chapter 3 Fibre to Fabric: Important Topics

Fibres are thin, long, flexible, and hair or thread-like structures. The fibres are usually obtained from two main sources- Plants and Animals. These fibers are called Natural Fibres. Cotton, wool, and silk are examples of Natural Fibres.

  • Wool

Wool is referred to as the textile fibre obtained from sheep and other animals, which includes cashmere and mohair from goats, qiviut from muskoxen, hide and fur clothing from bison, angora from rabbits, and other types of wool from camelids.

  • Silk

Silk is a natural protein fibre, some forms of which can be woven into textiles. The protein fibre of silk is formed mainly of fibroin, which is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity.
