Synthetic Fibres

Synthetic Fibres

1. Man Made fibres

2. Made from Polymers - long chains of molecules

   • Polymers are melted or dissolved in solution. This liquid is then forced through tiny holes & hardened to form filament fibres
     • The filaments are stretched into yarn and wound onto spools
       • Or chopped into staple lengths

3. They either come from coal or oil

   • Coal
     • Nylon
   • Oil
     • Polyester
     • Acrylic
     • Elastane
   • Non renewable source

4. less susstainable

5. They can be given many different properties

   • In general: not very absorbent = difficult to dye, they can be changed by applying heat = permanent pleats
