What is cotton fibre made of ?
Cotton fiber is made of cellulose, a natural polymer that is found in the cell walls of plants. The cotton fiber is produced by the cotton plant to protect its seeds, and it consists of around 90% cellulose, along with some waxes, pectin, and proteins. The individual fibers are long and thin, with a flattened, ribbon-like shape and a twisted, spiral structure. When these fibers are spun together, they create a yarn that can be woven or knitted into fabric. Cotton is one of the most widely used natural fibers in the world, prized for its softness, breathability, and durability.
