- Synthetic fibres and plastics ,like natural fibres, are made of very large units called polymers. Polymers are made up of many smaller units.
- While natural fibres are obtained from plants and animals, synthetic fibres are obtained by chemical processing of petrochemicals. Like natural fibres, these fibres can also be woven into fabrics.
- Synthetic fibres find uses ranging from many household articles like ropes, buckets, furniture, containers,etc., to highly specialized.uses in aircrafts, ships, spacecrafts,healthcare, etc.
- Depending upon the types of chemicals used for manufacturing synthetic fibres they are classified as, Rayon, Nylon, Polyster and Acrylic.
- The different type of fibres differ from one another in their strength, water absorbing capacity, nature of burning, cost, durability etc.
- Plastics have become a universal material, used for everything from throwaway bags to wings for combat aircraft. Plastics are cheap, lightweight, strong, often attractive, and can be synthesized with a wide range of properties.
- The waste created by plastics is not environment friendly. On burning, plastic release poisonous gases. On dumping in the ground they may take years to degenerate. This is because of their non-biodegradable nature.
