NCERT Class 7 Science chapter "Fibre to Fabric" introduces students to animal fibres and explains how wool and silk are obtained and transformed into useful fabrics. Students learn that wool comes from the fleece of sheep and other animals such as goats, yaks, camels, llamas, and alpacas. The chapter explains selective breeding of sheep, different wool-yielding animals, and the step-by-step process of converting animal hair into wool through shearing, scouring, sorting, dyeing, and spinning.
The chapter also explores the fascinating world of silk production. Students discover the life cycle of the silk moth, beginning from eggs and progressing through larva (silkworm), pupa, cocoon, and adult moth stages. They learn how silkworms produce silk fibres, how cocoons are formed, and how these fibres are extracted through the process known as reeling. The chapter introduces sericulture, the practice of rearing silkworms for silk production, and highlights the importance of mulberry leaves in feeding silkworms.
Through practical activities, illustrations, and real-world examples, learners understand the journey of fibres from animals to finished fabrics. The chapter develops awareness about textile production, animal resources, traditional industries, and the scientific processes involved in creating woollen and silk products. It encourages observation, scientific inquiry, environmental awareness, and appreciation for the contributions of people involved in the wool and silk industries.
