Synthetic Fibers:
Synthetic fibres are also known as artificial or man-made fibres. These fibres are created in factories using chemicals and technology, unlike natural fibres that come from plants or animals.
Examples:
- Some common synthetic fibres you might have heard of include nylon, dacron, terylene, terene, polyester, and rayon.
- These names are all different types of synthetic fibres, each with its own unique properties and uses.
Artificial threads
Reasons for the Development of Synthetic Fibers;
- Meeting Growing Demand
- Cost-Effectiveness
- Durability and Strength
- Consistency in Quality
- Versatility
