Cotton is a natural fabric harvested from crops, whereas polyester is a man-made polymer derived from natural chemicals. For decades, clothing manufacturers have used blended cotton and polyester so they can enjoy the benefits of both. The blend has a number of characteristics that make it ideal for use in modern clothing.

Cotton is a soft, fibrous material that grows from cotton plants and is a popular clothing fiber due how breathable it is. Cotton absorbs moisture well, retaining about 24 to 27 times its weight in water. Polyester, on the other hand, is a strong man-made fiber that resists creasing and wrinkling. It is a polymer that is a by-product of petrochemicals from coal, air water and oil. The DuPont Co. started producing polyester fiber in 1953.

The blend combines the comfort of cotton with the wrinkle resistance and sturdiness of polyester. It makes clothing easier to launder and more comfortable. It is durable, withstands higher temperatures and keeps its color longer. The material also dries quickly, and you can iron it at a lower temperature than pure cotton.

Manufacturers first started blending polyester with cotton in the 1960s, and it became popular in fashion worldwide due to its beneficial attributes. Despite its benefits, some consumers dislike the feel of polyester and request 100 percent cotton for more comfort. The polyester-cotton blend remains a common material in the manufacture of clothing today.

The United States, Far East and India are the top producers of polyester fabrics today. Manufacturers in Ireland also spin large amounts of polyester yarn. The United States and India are principal exporters of cotton as well, as are Brazil, Uzbekistan and Pakistan. The Far East, on the other hand, imports much of its cotton.
