Welcome to the chapter on Fibre to Fabric for Class 6. In this chapter, you will learn how the clothes we wear are made from fibres, the different types of fibres, and the steps involved in making fabric. By the end of this chapter, you will understand the journey from fibre to fabric!

Introduction

The clothes we wear are made from fabrics. Fabrics are made from fibres. Let’s learn how fibres are turned into fabric!

Types of Fibres

  • Natural fibres: Come from plants and animals. Examples: cotton, jute, silk, wool.

  • Cotton: Comes from cotton plants.
  • Jute: Comes from jute plants.
  • Wool: Comes from the fleece of sheep and goats.
  • Silk: Comes from silkworms.

Making Fabric from Fibre

  1. Harvesting: Collecting fibres from plants or animals.
  2. Spinning: Twisting fibres to make yarn.
  3. Weaving/Knitting: Making fabric by interlacing yarns.
  4. Dyeing: Coloring the fabric.
  5. Finishing: Making the fabric smooth and ready to use.

Uses of Different Fabrics

  • Cotton fabric is soft and used for shirts, dresses, and bedsheets.
  • Wool fabric is warm and used for sweaters and blankets.
  • Silk fabric is shiny and used for sarees and ties.
  • Synthetic fabrics are strong and used for raincoats and sportswear.
