Learning objective
Students must know the classifications of the following fibres, and be able to name examples that belong to each category: • natural fibres: • natural plant/cellulosic fibres – cotton, linen, ramie • natural animal/protein fibres – wool, silk • hair fibres – cashmere, mohair, angora • manufactured fibres: • regenerated fibres – viscose, acetate • new generation lyocells – Modal ®, Tencel®, Lyocell® • synthetic fibres: • polyamide (nylon), polyester, acrylic, elastomeric • chlorofibres (polyvinyl), fluorofibres (PTFE) • aramid fibres (Kevlar ®, Nomex®) • inorganic fibres including glass, carbon, metallic, ceramic • smart materials: • reactive materials • photochromic dyes • phase changing materials • modern materials: • microfibres • nano-fibres • microencapsulated fibres and fabric.

Why it matters
This objective helps connect Materials and their applications to exam-style questions, flashcards, and revision notes for Materials and their applications.
Quick student answer
Which of the following is a natural animal/protein fibre?
Direct answer
Wool is a natural animal/protein fibre obtained from sheep.
Key terms
- Elastomeric fibres: Fibres that can stretch significantly and return to their original length, providing elasticity in fabrics.
- Phase changing materials: Materials that can absorb, store, and release heat energy, helping to regulate temperature.
Common trap
Confusing natural and synthetic fibres: Remember that natural fibres come from plants or animals, while synthetic fibres are man-made, such as polyester or nylon.
