Fibre-yielding plants play a crucial role in both the economic and industrial sectors, providing materials that are widely used in textiles, ropes, paper, and other essential products. These plants are categorized into two main groups: natural fibres from plants and synthetic fibres. The major fibre-yielding plants include cotton (*Gossypium*), jute (*Corchorus*), flax (*Linum usitatissimum*), hemp (*Cannabis sativa*), and coir (from coconut *Cocos nucifera*).
