Cotton is a soft, staple fiber that grows around the seeds of the cotton plant i.e. Gossypium. The fiber is most often spun into yarn or thread and used to make a soft, breathable textile which is most widely used natural-fiber cloth in clothing today. Once the cotton is processed from the seeds, it is further processed to form a thread. When the cotton bolls are opened, the fibers dry into flat, twisted, ribbon-like shapes and become kinked together and interlocked. This interlocked form is ideal for spinning into yarn or thread.

Cotton thread is a fine continuous strand produced by plying two or more lengths of cotton strands with a tight twist and smooth finish. It is also made in varying thicknesses for various types of sewing. Although it is usually bleached, and bleaching is detrimental to the durability of thread, it is, and has been for more than 100 years, the most widely used thread for book sewing, especially in edition and library binding.

It is mainly used today for clothing purpose. Especially garment companies make the use of cotton commercially. The cotton being absorbent fiber can be mainly used in summer to absorb the sweat and also can be used in winter to keep the body warm.
