What Are the Differences Between Natural and Synthetic Fibres?
Understanding Natural Fibres And Synthetic Fibres is essential for exploring how materials are sourced, produced, and applied in everyday life. This topic is a fundamental part of chemistry and material science, revealing the unique properties, uses, and differences between fibres derived from nature and those created by human innovation. In this article, we’ll break down definitions, features, differences, and examples of each type, helping you easily distinguish between natural fibres and synthetic fibres for study or projects.
What are Natural Fibres?
Natural fibres are thread-like materials that come directly from plants or animals. These fibres are biodegradable, renewable, and have been used for thousands of years to make fabric, rope, and many other items. Their structure and properties largely depend on their biological source.
Common Natural Fibres Examples
- Cotton (from cotton plant)
- Wool (from sheep)
- Silk (from silkworms)
- Jute (from jute plant)
- Linen (from flax plant)
Characteristics of Natural Fibres
- Obtained from plant or animal sources
- Biodegradable and eco-friendly
- Good moisture absorption
- Less durable than synthetics
- Comfortable to wear, often hypoallergenic
What are Synthetic Fibres?
Synthetic fibres are man-made fibres produced through chemical processes, typically using polymers derived from petrochemicals. These fibres are designed to enhance durability, strength, and resist factors like water and stains, making them ideal for a variety of modern uses.
Examples of Synthetic Fibres
- Nylon
- Polyester
- Acrylic
- Rayon (semi-synthetic)
- Spandex (Lycra)
Properties of Synthetic Fibres
- Produced through chemical synthesis
- Usually more durable and elastic
- Resist wrinkles, water, and pests
- Non-biodegradable (except for some newer eco-versions)
- Can cause discomfort or allergies for some users

Difference Between Natural Fibres and Synthetic Fibres
The difference between natural fibres and synthetic fibres can be summarized as follows:
- Natural fibres are sourced from nature, environmentally friendly, and comfortable, but may have lower strength and durability.
- Synthetic fibres are engineered for resilience, are less eco-friendly, and may lack breathability or comfort compared to natural options.

In conclusion, natural fibres and synthetic fibres each provide unique advantages and limitations. Natural fibres offer sustainability and comfort, making them ideal for eco-conscious uses, while synthetic fibres deliver strength, versatility, and longer lifespan. Understanding their difference is critical for selecting materials for textiles, industry, and everyday products, and is a key concept across many chemistry lessons and projects. Whether you’re studying for a natural fibres and synthetic fibres project or preparing a comparison chart, this distinction guides smart and responsible material choices.
FAQs on Understanding Natural and Synthetic Fibres
1. What are natural fibres and synthetic fibres?
Natural fibres are fibres obtained from plants and animals, while synthetic fibres are made by humans using chemical processes.
Key points:
- Natural fibres: Examples include cotton, jute, silk, wool.
- Synthetic fibres: Examples include nylon, polyester, acrylic, rayon.
- Natural fibres are biodegradable, but synthetic fibres are usually not.
- Synthetic fibres are strong, elastic, and durable compared to most natural fibres.
2. What are examples of natural fibres?
Examples of natural fibres include fibres that come from plants or animals.
Common examples:
- Cotton (from cotton plants)
- Jute (from jute plants)
- Wool (from sheep, goats)
- Silk (from silkworms)
- Coir (from coconut husks)
3. Give examples of synthetic fibres.
Synthetic fibres are man-made fibres created using chemicals.
Popular examples:
- Nylon
- Polyester
- Acrylic
- Rayon (semi-synthetic)
- Spandex (lycra)
4. What are the differences between natural and synthetic fibres?
The primary difference is based on their origin and properties.
- Source: Natural fibres come from plants/animals; synthetic fibres are chemically made by humans.
- Biodegradability: Natural fibres are biodegradable, but most synthetic ones are not.
- Strength and durability: Synthetic fibres are more durable and stronger.
- Cost: Natural fibres are usually costlier to produce than synthetic fibres.
- Feel: Natural fibres are more comfortable, while synthetic fibres may cause irritation in some people.
5. How are synthetic fibres made?
Synthetic fibres are produced by chemical processes, mainly from petroleum-based products called petrochemicals.
Manufacturing process:
- Monomers (small molecules) are chemically joined to form polymers (large chains).
- The polymer is melted/spun into threads and cooled to form fibres.
- Examples: Making nylon, polyester, acrylic by polymerisation and spinning methods.
6. Why are synthetic fibres preferred over natural fibres for certain uses?
Synthetic fibres are often preferred due to their unique properties.
Advantages:
- High strength and durability
- Elasticity and wrinkle resistance
- Cheaper to produce and maintain
- Quick drying and easy to wash
- Used for sportswear, umbrellas, car tyres, ropes, etc.
7. What are the disadvantages of synthetic fibres?
Synthetic fibres, despite their benefits, have some disadvantages.
Main drawbacks:
- They are not biodegradable, causing environmental problems.
- Some can melt on heating or catch fire easily.
- Less comfortable than natural fibres in hot weather.
- Can cause skin irritation or allergies in sensitive people.
8. What are the uses of natural fibres?
Natural fibres are used widely in daily life.
Common uses:
- Cotton: Clothes, bedsheets, towels
- Wool: Winter wear, blankets
- Jute: Gunny bags, ropes, mats
- Silk: Sarees, ties, scarves, luxury clothing
9. What are the environmental impacts of synthetic fibres?
Synthetic fibres have serious environmental effects mainly due to their non-biodegradability.
- They accumulate in landfills and do not decompose quickly.
- Microplastics from washing synthetic clothes pollute water bodies.
- Production releases harmful chemicals into the environment.
- Contributes to plastic pollution.
10. Explain the process of making yarn from fibres.
The process of making yarn from fibres is called spinning.
Steps:
- Fibres are drawn out and twisted to form a long, continuous thread called yarn.
- Spinning aligns fibres and increases yarn strength.
- Yarn is then used for weaving or knitting to make fabrics.
11. What is the difference between natural and synthetic fibres? (scraped)
Natural fibres are derived from plants or animals, while synthetic fibres are man-made from chemical substances.
- Natural fibres are biodegradable; synthetic fibres are not.
- Natural: cotton, wool, silk; Synthetic: nylon, polyester.
- Synthetic fibres are usually stronger and elastic.
12. What are natural fibres? (scraped)
Natural fibres come from plants or animals.
Examples include:
- Cotton (plant)
- Jute (plant)
- Wool (animal)
- Silk (animal)
13. What are synthetic fibres? (scraped)
Synthetic fibres are made by humans from chemicals mainly derived from petroleum.
Examples:
- Nylon
- Polyester
- Acrylic
14. State two uses each of natural and synthetic fibres. (scraped)
Natural fibres: Used for clothing like shirts and sarees, and making ropes or sacks.
Synthetic fibres: Used in sportswear/clothing, and in making ropes, umbrellas, and tents.
15. Why are synthetic fibres called man-made fibres? (scraped)
Synthetic fibres are called man-made fibres because they are produced by humans by chemical processes, unlike natural fibres that come from plants or animals.
