ThinkRankSynthetic Fibres and Plastics
Synthetic fibres are made from chemical substances and can be designed for strength, elasticity, lightness, or resistance. Plastics are useful because they are durable and versatile, but the same durability creates waste and pollution. Responsible material choices require reuse, recycling, safer design, and reduced consumption.
Learning Objectives
- •Explain properties and uses
- •Explain plastics have trade-offs
- •Explain responsible use
Key Concepts
Properties and uses
Rayon, nylon, polyester, and acrylic have different properties that make them suitable for particular products.
Plastics have trade-offs
Plastic can be light, waterproof, and durable, but it can persist in the environment and harm animals when mismanaged.
Responsible use
Refuse, reduce, reuse, repair, and appropriate recycling are more effective than treating recycling as a complete solution.
Terminology
Historical Insight
Sports clothing
Synthetic fibres can be engineered to dry quickly, but design and disposal still affect environmental cost.
Thermosetting plastic
Handles of cooking utensils may use plastics that retain shape when heated and cannot be remoulded easily.
