- 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
- Liquid is forced through holes and hardened to form filament fibres
- 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
- Natural
