Fibre to Fabric
Overview
From T-shirts to sarees — all clothes are made from yarn, and yarn comes from plants like cotton and jute. This chapter covers the complete journey from fibre to fabric — ginning, spinning, and weaving.
Typed Notes
What is Fibre — Two Families
Fibre is the thin, thread-like material from which cloth is made. There are two families: (1) Natural fibres — either from plants: cotton, jute, linen (flax); or from animals: silk (from the cocoon of the silkworm), wool (from the hair of sheep and goats). (2) Synthetic fibres — made in factories using chemicals: nylon, polyester, acrylic. Natural fibres are breathable and feel comfortable in hot weather; synthetic fibres are cheap and strong but feel sticky in the heat.
The Journey of Cotton and Jute
Cotton grows in hot regions (Maharashtra, Gujarat, Madhya Pradesh) — white fluffy balls called bolls are picked; these contain seeds along with the fibre. Ginning separates the seeds from the fibre. Jute grows in wet soil (West Bengal, Bihar) — its long stems are soaked in water (retting) so that the fibres separate — these fibres are then used to make sacks and jute bags.
Spinning and Weaving/Knitting
Spinning — pulling small fibres and twisting them together to make a long thread (yarn). The spinning wheel (charkha) was an early invention — Gandhiji made it a symbol of Swaraj; today spinning machines are used. There are two ways to make fabric: Weaving — two separate threads (one along the length and one along the width) are passed over and under each other (on a handloom or powerloom) — this makes fabric for sarees and shirts. Knitting — loops are formed using a single thread — this makes sweaters, mufflers, and T-shirts (the triangular loops can stretch).
A Lesson from History
Thousands of years ago, people made cloth from cotton, wool, and silk — pieces of cotton have been found at Harappa (among the oldest in the world). Before machines, everything was done by hand — using the spinning wheel and handloom. Gandhiji made the charkha and khadi a weapon of freedom — 'make it yourself, use it yourself'. Even today, khadi cloth is a symbol of pride.
Key Concepts
Revision ke liye ek nazar — exam se pehle yahi padhna hai.
- 01Natural fibres: cotton, jute, silk, wool (from plants and animals). Synthetic fibres: nylon, polyester (made in factories).
- 02Cotton: grown in hot regions — Maharashtra, Gujarat. Jute: grown in wet soil — Bengal. Jute stems are soaked in water (retting).
- 03Ginning: separating seeds from cotton fibre. Spinning: making yarn from fibre. Weaving: making fabric from two threads; knitting: making fabric from loops of one thread (like sweaters).
- 04After picking cotton: ginning → spinning → weaving/knitting — this is the complete journey from fibre to fabric.
- 05History: thousands of years ago people made cloth from cotton and wool fibres; Gandhiji made the spinning wheel (charkha) a symbol of self-rule (Swaraj).
Questions & Solutions

What is the difference between ginning and spinning?
How are weaving and knitting different?
Where is jute grown and how is the fibre extracted?
Give two examples each of natural and synthetic fibres.
Where do silk and wool come from?
Fibre → yarn → fabric. Cotton and jute come from plants, silk and wool come from animals (natural); nylon and polyester come from factories (synthetic). Ginning (separating seeds), spinning (making yarn from fibre), weaving/knitting (making fabric from yarn). Jute stems are soaked in water (retting).
