1. Cotton
Overview of Cotton
Split in two by the African branch. All thanks to cotton, the most harvested natural fibre in the world. Soft, airy, versatile, cotton is a staple fibre: it consists of short fluffy fibres, drawn thread by thread to form yarns, which are woven to make fabrics. The cotton plant belongs to the genus Gossypium and is grown in tropical and subtropical areas of the world.
History and Global Production
Cotton has been in use for thousands of years: archaeological evidence shows it being used in India by 5000 BCE and in Peru by 3000 BCE. By the time of the Industrial Revolution, the fibre was intimately connected to the expansion of globalised capitalism and new capitalist technologies such as the cotton gin, invented by Eli Whitney in 1793.
Cotton is harvested in more than 80 nations worldwide today. China, India, the United States, Pakistan and Brazil are the world’s top cotton-producing countries. Together, they account for more than half of global cotton supply. Millions work in the industry worldwide.
Key Characteristics and Properties
Cotton is prized for several key properties:
Softness: Cotton has soft fibres, with a high length-to-diameter ratio, making them smooth, comfortable to wear and pleasing to the touch.
Breathability: Cotton allows air to circulate, which helps keep the body cool and dry.
Absorbency: Cotton can absorb 27 times its own weight in water.
Durability: Cotton fibers are strong and can withstand repeated washing and wear.
Hypoallergenic: Cotton is less likely to cause allergic reactions compared to synthetic fibers.
Uses in Textiles
Common Applications
Cotton is used in a wide range of textile applications:
- Clothing: From everyday wear like t-shirts and jeans to formal wear and activewear, cotton is a staple in the fashion industry.
- Home Textiles: Cotton is commonly used in bedding (sheets, pillowcases, comforters), towels, and upholstery due to its softness and durability.
- Industrial Textiles: Cotton is used in products like canvas, tarps, and medical supplies (bandages, gauze) due to its strength and absorbency.
Advantages and Disadvantages
Advantages:
- Comfortable and breathable
- Versatile and widely available
- Biodegradable and recyclable
- Durable and easy to care for
Disadvantages:
- High water usage in cultivation
- Vulnerable to pests, requiring pesticides
- Can shrink and wrinkle easily

Environmental Impact
Water Usage
Cotton is notorious for its high water usage. It takes approximately 2,700 liters of water to produce a single cotton t-shirt. This high demand for water can lead to depletion of local water sources, especially in arid regions where cotton is often grown.
Pesticides and Fertilizers
Cotton cultivation frequently involves the use of pesticides and fertilizers to protect crops and enhance yields. These chemicals can have detrimental effects on the environment, including water pollution, soil degradation, and harm to wildlife.
Soil Degradation and Sustainability Efforts
Intensive cotton farming can lead to soil degradation, reducing soil fertility and increasing erosion. However, there are ongoing efforts to promote more sustainable practices in cotton production. Organic cotton farming, for example, avoids synthetic pesticides and fertilizers, focusing instead on natural alternatives and crop rotation to maintain soil health.
