Polyester is a synthetic fiber derived from coal, air, water, and petroleum. Developed in a 20th-century laboratory, polyester fibers are formed from a chemical reaction between an acid and alcohol.
Poly-cotton blends are strong, durable and tear-resistant, thanks to the fact that polyester fibers are far more elastic than cotton alone. Also, polyester doesn't shrink and change shape the way cotton does, giving users of the blend more latitude in how the fabric is washed and dried. However, thanks to the cotton component, blends are very abrasion-resistant and far more breathable than pure polyester.
