Explain why some fibres are called synthetic.

Fibres are classified as synthetic when they are man-made, created through chemical processes rather than derived from natural sources like plants or animals. These materials are designed to mimic the properties of natural fibres while offering unique advantages.

Characteristics of Synthetic Fibres

Synthetic fibres have several distinct features that set them apart:

• Durability: They tend to be more resistant to wear and tear compared to natural fibres.
• Moisture Resistance: Many synthetic fibres repel water, making them suitable for various applications.
• Color Retention: They hold dyes well, resulting in vibrant colors that last longer.
• Cost-Effectiveness: Generally, synthetic fibres are cheaper to produce, making them widely available.

Common Types of Synthetic Fibres

Some popular synthetic fibres include:

• Polyester: Known for its strength and wrinkle resistance.
• Nylon: Famous for its elasticity and durability.
• Acrylic: Often used as a wool substitute due to its warmth.

In summary, synthetic fibres are engineered materials that provide specific benefits, making them a popular choice in the textile industry and beyond.
