Learning objective
Students should be able to explain the different fibres and their specific performance characteristics, including: • plant/cellulose fibres: very absorbent, little elasticity, good strength, poor insulators • animal/protein fibres: very absorbent, thermally insulating • regenerated fibres: poor strength, soft, highly absorbent, crease badly • new generation lyocells: with improved performance characteristics • synthetic fibres: very good strength, totally non-absorbent, smooth, lightweight, do not crease, can be heat set (thermoplastic).
Read the explanation, check the common trap, then practise with flashcards and questions.

Why it matters
This objective helps connect Performance characteristics of materials to exam-style questions, flashcards, and revision notes for Performance characteristics of materials.
Quick student answer
Which of the following fibres is known for being thermally insulating?
Direct answer
Wool is an animal/protein fibre that provides excellent thermal insulation due to its natural crimp and structure.
Key terms
- Thermal Insulation: The ability of a material to resist the transfer of heat, keeping the wearer warm.
- Moisture-wicking: The ability of a fabric to draw moisture away from the body to the surface of the fabric, where it can evaporate.
Common trap
Confusing fibre types: Review the specific characteristics of each fibre type to understand their unique properties.
