Cotton fiber is a plant-based natural fiber. Cotton textiles have good breathability and excellent comfort due to their high hydrophilicity, and they produce no or very few allergic reactions. Therefore, it can be used in applications related to sensitive consumers such as infants and the elderly, as well as goods with direct skin contact such as linens, socks and underwear. Additionally, they are a popular choice for summer clothing due to their high hydrophilicity and breathability. The quality of cotton fibers depends on the length, fineness and color of the fibers. The longer, finer, and whiter the fiber, the higher the quality. Cotton fiber is mainly spun by ring spinning.
