Quick student answer
Which of the following fabrics is characterized by a looped texture and is often used in high-end fashion?
Direct answer
Bouclé is a fabric that features a looped texture, making it popular in high-end fashion for its unique appearance.
Key terms
- Crêpe: A lightweight fabric with a crinkled or textured surface, often used in dresses and blouses.
- Metallic fibres: Fibres that contain metallic elements, providing shine and enhancing the durability of fabrics.
Common trap
Confusing crinkle with permanent creasing: Remember that crinkle fabrics are designed to look wrinkled, while permanent creasing involves setting a crease that remains sharp and defined.

Performance characteristics of materials
- Students should be able to name different types of fibres.
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.
