Dacron
- Dacron is a copolymer, strong and impact resistant.
- It is colourless and has high transparency.
- It is mainly used for synthetic fibres.
- Mixing it with various amounts of cotton gives fabrics that are durable, easily dyed and crease-resistant.
- It is also used for making bottles and packaging materials.
Dacron is a copolymer that is formed when equimolar amounts of 1,4-benzene dicarboxylic acid ( terephthalic acid ) and 1,2-ethanediol (ethylene glycol ) react.
Ethylene glycol and terephthalic acid is polymer of Dacron.
Additional Information
- Polyacrylonitrile or Arlon is a condensation polymer where condensation of acetonitrile occurs with the elimination of small units like ammonia.
- Rayon is also known as a semi-synthetic fiber as its raw material is obtained from natural sources but processed synthetically.
- Nylon is formed with adipic acid and Hexamethylene diamine.
