A textile fibre is a fine, hair-like substance that can be spun into yarn or made into fabric through weaving, knitting, felting, braiding, or other textile manufacturing processes. Textile fibres are the basic raw materials used in the production of clothing, household textiles, industrial fabrics, and technical textiles. They may be obtained from natural sources such as plants, animals, and minerals, or produced artificially through chemical processes as regenerated or synthetic fibres. A fibre suitable for textile use should possess specific physical, mechanical, and chemical properties that enable it to be processed into durable and comfortable fabrics. One of the most important properties is adequate length. Fibres must have sufficient length to overlap and twist together during spinning, forming a strong and continuous yarn. Longer fibres generally produce smoother, stronger, and finer yarns, while shorter fibres require more twisting and may produce fuzzier fabrics. Strength is another essential property. A textile fibre should be able to withstand the stresses involved in spinning, weaving, knitting, dyeing, finishing, and regular use. Strong fibres increase the durability and service life of textile products. Cotton, polyester, and nylon are examples of fibres with good tensile strength. Flexibility is necessary
