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.
