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 has the highest absorbency?
Direct answer
Cotton is known for its high absorbency, making it suitable for clothing that requires moisture management.
Key terms
- Elasticity: The ability of a fabric to stretch and return to its original shape.
- Thermal Insulation: The property of a fabric to retain heat and provide warmth.
Common trap
Confusing absorbency with moisture-wicking: Absorbency refers to how much moisture a fabric can hold, while moisture-wicking describes how well a fabric moves moisture away from the body.

Performance characteristics of materials
- 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).
Performance characteristics of materials
- Students should be able to explain the shape and formation of fibres. They should understand and be able to discuss the different cross- sectional and linear formation of fibres that can occur in natural form, and those that can be engineered during synthetic and manmade fibre production. Understand how the physical shape and formation of fibres affect their performance. 12 Visit aqa.org.uk/7562 for the most up-to-date specification, resources, support and administration Fibre production.
