Fibres are long strands of durable material, such as hemp, cotton or fleece, which are harvested from natural sources in order to confection textiles. The durability, capabilities and looks of all textiles directly depend on the fibres it is made from. Naturally, this is the main driver behind a specific type of fibre's market price. In the mid-1960s, the role of fibre production in the clothing industry has largely been surpassed by artificial alternatives such as nylon, but textiles spun from natural fibres tend to have certain advantages, such as much greater protection from the cold, and being less itchy.
