Chapter 8: Clothes — How Things are Made

The complete journey of a cotton garment involves six key stages:

1. Cultivation & Harvesting: Cotton crops grow best in black clay soil and warm sunshine. When ripe, fluffy white cotton bolls burst open and are handpicked by farmers.
2. Ginning: Picked cotton contains seeds and dirt. A ginning machine separates raw cotton fibres (lint) from cotton seeds.
3. Spinning: Raw lint is combed, drawn out, and twisted into long continuous threads called yarn using spindles, charkhas, or industrial spinning mills.
4. Weaving or Knitting: On a handloom or powerloom, two sets of yarn—the warp (lengthwise) and weft (crosswise)—are interlaced at right angles to weave fabric sheets.
5. Dyeing, Bleaching & Printing: The plain grey fabric is washed, bleached, colored with dyes, and printed with decorative patterns.
6. Stitching (Tailoring) & Packaging: Tailors cut the cloth according to patterns and stitch buttons, collars, and seams into finished shirts sent to retail stores.

Comparison of Fibre Types:

Characteristic	Natural Fibres	Synthetic Fibres
Source	Obtained directly from plants and animals	Artificially synthesized from petrochemicals
Breathability & Comfort	Highly breathable, absorbs sweat, skin-friendly	Less breathable, traps heat, can cause irritation
Environmental Impact	100% Biodegradable; decomposes naturally	Non-biodegradable; sheds microplastics
Examples	Cotton, Jute, Wool, Silk	Nylon, Polyester, Acrylic

The rearing of silkworms for commercial silk production is called Sericulture:

1. Egg to Caterpillar: Female silk moths lay hundreds of eggs that hatch into tiny caterpillars (silkworm larvae).
2. Feeding on Mulberry Leaves: The caterpillars have voracious appetites and feed continuously on fresh green mulberry leaves for about 25 to 30 days, growing rapidly in size.
3. Spinning the Cocoon: When fully grown, the silkworm swings its head in figure-eight patterns, secreting a liquid protein from salivary glands that hardens on contact with air into a continuous fine silk thread (up to 1,000 metres long). The caterpillar wraps itself completely in this protective oval shell called a cocoon.
4. Reeling Silk: The cocoons are placed in boiling water to soften the sticky gum (sericin). Workers unwind the long, lustrous filaments and spin them into silk yarn.

During India's freedom struggle, Mahatma Gandhi promoted Khadi (homespun cotton cloth) and the Charkha as powerful symbols of national self-reliance (Swavalamban) and resistance:

1. Boycott of British Mill Cloth: The British Empire exported raw Indian cotton cheaply to English mills in Manchester and sold expensive machine-made clothes back to Indians, ruining native village weavers. Gandhi urged citizens to boycott foreign textiles.
2. Economic Empowerment: Spinning on the Charkha provided supplemental income and dignity of labor to impoverished rural villagers.
3. Social Equality: When rich and poor, upper and lower castes all wore simple white Khadi, it dissolved social hierarchies and unified the country.

Household Wardrobe Label Investigation:

Garment	Fibre Composition	Fibre Class	Care Instruction
School Summer Shirt	100% Cotton	Plant Natural	Machine wash warm; iron hot
Winter Pullover	100% Pure Wool	Animal Natural	Hand wash cold; dry flat
Sports Track Pants	100% Polyester	Synthetic Chemical	Do not iron hot; quick drying
Traditional Kurta	Cotton-Silk Blend	Mixed Natural	Gentle hand wash with mild detergent

Discarding clothes in landfills creates severe environmental hazards:

1. Microplastic Pollution: Synthetic fabrics (polyester, nylon) take up to 200 years to decompose, shedding microplastic fibres into soil and groundwater.
2. Wasted Resources: It takes thousands of litres of fresh water and pesticides to cultivate the cotton for a single shirt. Discarding wearable garments wastes these precious natural inputs.

Sustainable Solutions:

• Upcycling: Old denim jeans and torn bedsheets can be stitched into sturdy vegetable grocery tote bags, aprons, or floor mats.
• Donation: Clean, outgrown clothes should be donated to community shelters, orphanages, or disaster relief drives so other families can benefit.
