Quick student answer
Which of the following is a characteristic of staple fibres?
Direct answer
Staple fibres are short fibres that are often derived from natural sources such as cotton, wool, and flax. They have a defined length, which contributes to the texture and feel of the fabric.
Key terms
- Staple Fibres: Short fibres that are spun together to create yarn, typically derived from natural sources.
- Continuous Filament Fibres: Long, continuous strands of fibre produced through extrusion, often made from synthetic materials.
Common trap
Confusing staple and continuous filament fibres: Remember that staple fibres are short and derived from natural sources, while continuous filament fibres are long and often synthetic.

Performance characteristics of materials
- Students should be able to describe the performance characteristics of fibres, including: • absorbency • strength • elasticity • flammability • thermal qualities • lustre • handle.
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.
