🧶 The Complete Classification of Fibres
1. Definition of Fibre
A fibre is a fine, hair-like structure that is either naturally occurring or man-made. It is the fundamental building block of yarns and fabrics. Fibres are characterized by high length-to-width ratios and can be spun or woven into textiles.
In the world of textiles, fibres play a critical role in determining the fabric’s texture, appearance, strength, and suitability for specific purposes—be it fashion, furnishings, industrial applications, or medical use.
2. Purpose of Fibres
- Clothing & Fashion: Fibres are the starting point for making garments that protect and decorate the human body.
- Comfort & Functionality: Provide warmth, breathability, flexibility, or waterproofing depending on the type.
- Industrial Use: Used in automotive interiors, geotextiles, construction, and packaging materials.
- Medical & Technical Use: Special fibres are used in surgical sutures, bandages, and protective gear.
3. Classification of Fibres
Fibres are broadly classified into two main categories based on their origin:
- Natural Fibres: Obtained from nature—plants, animals, or minerals.
- Man-Made Fibres: Synthesized through chemical or mechanical processes.
4. Natural Fibres
These fibres are biodegradable and eco-friendly. They are extracted directly from natural sources and have been used by humans for thousands of years.
🌿 Plant-Based (Cellulose Fibres)
- Cotton: Grown in warm climates, cotton is soft, breathable, and highly absorbent. It is ideal for summer wear, bedding, and undergarments.
- Flax (Linen): Made from the stalks of flax plants, it is stronger than cotton and has a crisp texture. Common in suits and home furnishings.
- Jute: Known for its roughness, it is strong and used in eco-friendly bags, sacks, and carpets.
- Hemp: Extremely durable, resistant to UV rays and mold, used in bags, ropes, and sustainable apparel.
- Coir: Derived from coconut husk, used in doormats and brushes.
🐑 Animal-Based (Protein Fibres)
- Wool: Obtained from sheep. It is warm, elastic, and moisture-resistant. Ideal for winter wear and blankets.
- Silk: Produced by silkworms. Known for its smooth texture and shine. Popular in luxury clothing and bedding.
- Cashmere: A fine, soft wool from goats, used in premium winter garments.
- Alpaca & Mohair: Softer and warmer than sheep wool, sourced from alpacas and angora goats respectively.
🪨 Mineral-Based Fibre
- Asbestos: A natural mineral fibre formerly used for its fireproof properties in insulation, now banned in many countries due to health risks.
5. Man-Made Fibres
These are engineered through chemical or mechanical processes. They are categorized into:
🔄 Regenerated (Semi-Synthetic) Fibres
- Rayon: Made from wood pulp and mimics silk in feel. Used in dresses, blouses, and linings.
- Modal: Smoother than rayon and more absorbent. Common in underwear, nightwear, and activewear.
- Lyocell: Eco-friendly version of rayon with low environmental impact. Soft and strong; used in luxury wear and home textiles.
🧪 Synthetic Fibres
- Polyester: Extremely durable, wrinkle-resistant, and low maintenance. Widely used in fashion and home furnishings.
- Nylon: Strong, elastic, and abrasion-resistant. Used in hosiery, swimwear, and industrial ropes.
- Acrylic: Resembles wool; lightweight and warm. Used in sweaters, blankets, and outdoor fabrics.
- Spandex (Lycra): Highly stretchable. Found in athletic wear, leggings, and compression garments.

7. Question-Answer
Q1. What is a fibre?
A fibre is a long, slender, thread-like structure that forms the raw material of yarns and fabrics. It can be natural or synthetic, and each type has specific uses and properties.
Q2. What are the main types of fibres?
Fibres are mainly classified into two types: natural fibres (from plants and animals) and man-made fibres (chemically produced or regenerated).
Q3. Which fibre is best for summer?
Cotton is best for hot weather because it is breathable, absorbs sweat, and keeps the body cool.
Q4. Which fibre is best for winter?
Wool is ideal for winter as it provides insulation, retains body heat, and resists moisture.
Q5. Which is the most luxurious natural fibre?
Silk is considered the most luxurious due to its sheen, smoothness, and exclusivity.
Q6. Which fibre is best for stretchability and sports?
Spandex (Lycra) offers exceptional stretch and comfort, perfect for sportswear and yoga outfits.
Q7. Which fibre is most eco-friendly?
Organic cotton and Lyocell are environmentally friendly choices because they are biodegradable and produced with minimal chemical impact.
