Fibres

Synthetic fibres

• are natural and derived from plants

• are man-made and created from different chemicals

• are always biodegradable

• are less durable than natural fibres

Polymerisation

• The process of breaking down large molecules into smaller units.

• The reaction in which many small repeating units called 'monomers' are joined together to form a large molecule 'polymer' under suitable conditions of temperature and pressure.

• A method of synthesizing proteins from amino acids.

• The process of converting a solid into a liquid by heating.

Synthetic fibers

• Natural fibers derived from plants and animals.

• Man-made fibers produced from chemical substances.

• Fibers that are only used in clothing.

• Fibers that cannot be recycled.

Natural fibres

• come from synthetic materials like plastics.

• come from natural sources like plants and animals.

• are exclusively made from animal products.

• are produced in factories using chemicals.
