Learning objective
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.

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 fibre shapes is most likely to enhance moisture-wicking properties?
Direct answer
Hollow fibres are designed to trap air and moisture, allowing for better moisture-wicking properties.
Key terms
- Tensile Strength: The resistance of a material to breaking under tension.
- Moisture Management: The ability of a fabric to absorb, transport, and evaporate moisture.
Common trap
Confusing fibre types: Focus on the unique characteristics of each type, such as moisture absorption in natural fibres versus durability in synthetic fibres.

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).
