Answer:
1. Plant fibres include seed hairs, such as cotton; stem (or bast) fibres, such as flax and hemp; leaf fibres, such as sisal; and husk fibres, such as coconut. Animal fibres include wool, hair and secretions, such as silk.
2. Natural fibres can be classified according to their origin. The vegetable, or cellulose-base, class includes such important fibres as cotton, flax, and jute. The animal, or protein-base, fibres include wool, mohair, and silk. An important fibre in the mineral class is asbestos.
3.All fabrics can be characterized as either natural or synthetic fibers (or a blend of the two). Both types have pros and cons; natural fibers come from plants and animals, while synthetic fibers are made from chemical compounds, and each is valued in the textile industry for different reasons.
Plants including cotton, jute, flax and hemp are used to obtain plant fibres
