  • Types of Fibre
    • Natural
      • Come from natural sources - plants and animals
      • Cotton and Linen come from plants
      • Wool from sheep and other animals
      • Silk comes from silkworms
      • Natural usually comes in staple lengths
        • The exception is silk, these are filament fibres
      • After they're harvested, they're cleaned and straightened
        • They are then spun into a yarn
      • Fibres come from renewable sources, and are often biodegradable and recyclable
      • They are absorbent and strong
      • They have poor resistance to biological damage
    • Regenerated
      • Made from natural materials that are chemically treated to produce fibres
      • Different fibres are made from different chemicals
      • Fibres have a renewable origin but many are made using synthetic chemicals
      • Less sustainable than natural fibres
      • Some regenerated fibres, like Tencel, use chemicals that can almost all be recycled
      • Tend to have similar properties to natural fibres
        • Can be given different properties by using chemicals
    • Synthetic
      • Made from polymers - molecules mainly from coal or oil
      • Man Made fibres
      • Polyester, LYCRA, Acylic are produced from oil
      • Nylon is produced from coal
      • Polymers are melted and dissolved in solution
        • Liquid is forced through holes and hardened to form filament fibres
          • Filaments are stretched into a yarn - wound onto spools/chopped into staple lengths
          • Regenerated
            • Made from natural materials that are chemically treated to produce fibres
            • Different fibres are made from different chemicals
            • Fibres have a renewable origin but many are made using synthetic chemicals
            • Less sustainable than natural fibres
            • Some regenerated fibres, like Tencel, use chemicals that can almost all be recycled
            • Tend to have similar properties to natural fibres
              • Can be given different properties by using chemicals
      • Made from non renewable sources - less sustainable than other fibres
      • These can be given many different properties
      • They're resistant to biological damage
      • Can be changed by heating to form different shapes and textures
