Study Notes
Types of Fibres and their Sources
- Fibres are tiny strands spun or twisted to make yarns/threads.
- Natural fibres are obtained from plant/vegetable sources (cotton and linen) and animal sources (silk and wool).
- Cotton is obtained from the boll (seed pod) of the cotton tree, and linen is obtained from the stalk (stem) of the flax plant.
- Silk is obtained from the cocoon of the silk worm, while wool is obtained from the fleece of the sheep.
- Man-made fibres are created in the laboratory using chemicals, such as polyester, acrylic, and nylon.
- These chemically made fibres are known as Synthetic or Non-Cellulosic Fibres.
- Man-made fibres can also be created with a combination of chemicals and cellulose, such as rayon, acetate, and triacetate.
- These man-made fibres are known as Regenerated or Cellulosic Fibres.
- Synthetic fibres are produced solely from chemicals, while regenerated fibres are produced from a combination of chemicals and cellulose.
- Examples of synthetic fibres include polyester, acrylic, and nylon.
- Examples of regenerated fibres include rayon, acetate, and triacetate.
- Natural fibres include cotton, linen, silk, and wool, while man-made fibres include synthetic and regenerated fibres.
