**Difference between Synthetic and Natural Fibres**

Fibres are materials that are used to make fabrics. They can be classified into two types: synthetic fibres and natural fibres. The main difference between these two types of fibres lies in their origin and composition.

**Natural Fibres:**

Natural fibres are derived from natural sources such as plants and animals. They have been used for thousands of years to make clothing, ropes, and other textiles. Some common examples of natural fibres include cotton, wool, silk, and jute.

1. **Source**: Natural fibres are obtained from plants (cotton, jute) and animals (wool, silk). These fibres are either derived from the stem, seeds, leaves, or the fur of the animals.

2. **Composition**: Natural fibres are made up of complex organic compounds, mainly cellulose (in case of plant fibres) and protein (in case of animal fibres).

3. **Properties**: Natural fibres are known for their breathability, comfort, and biodegradability. They can absorb moisture and allow air to pass through, making them suitable for clothing in hot climates. However, they may shrink or lose their shape when exposed to heat or moisture.

4. **Strength**: Natural fibres have varying degrees of strength. For example, silk is known for its strength and elasticity, while cotton is relatively weaker.

5. **Care**: Natural fibres require proper care to maintain their quality and durability. They may need special washing instructions and can be damaged by harsh chemicals or improper handling.

**Synthetic Fibres:**

Synthetic fibres are man-made fibres that are created through chemical processes. They are derived from petrochemicals or polymers and are designed to mimic the properties of natural fibres. Some common examples of synthetic fibres include polyester, nylon, and acrylic.

1. **Source**: Synthetic fibres are produced in laboratories using chemicals and polymers derived from petroleum products.

2. **Composition**: Synthetic fibres are made up of synthetic polymers such as polyester, nylon, and acrylic. These polymers are derived from petroleum or coal.

3. **Properties**: Synthetic fibres are known for their strength, durability, and resistance to wrinkles and fading. They do not absorb moisture like natural fibres, making them suitable for sportswear and outdoor clothing. However, they may not be as breathable or comfortable as natural fibres.

4. **Strength**: Synthetic fibres are generally stronger than natural fibres. For example, nylon is known for its exceptional strength and abrasion resistance.

5. **Care**: Synthetic fibres are relatively easy to care for and can withstand machine washing and drying. They are less prone to shrinking or losing their shape compared to natural fibres.

In conclusion, the main difference between synthetic and natural fibres lies in their origin, composition, properties, strength, and care requirements. Natural fibres are derived from plants and animals, while synthetic fibres are man-made from chemicals and polymers. Natural fibres are known for their breathability and comfort, while synthetic fibres are valued for their strength and durability.
