A one-page encyclopedia entry defining fibre as a filament or thread of animal or vegetable origin and surveying the materials used for textiles and cordage. It covers animal fibres (wool, hair, silk), the one fibrous mineral (asbestos), and vegetable fibres by plant source: bark (flax, hemp, jute), fruit and seed hairs (cotton, coir), and leaves (New Zealand flax, Manila hemp, pita). It also briefly mentions how bark and leaf fibres are separated, by steeping or by beating and rolling.
