Polyester is a type of synthetic fiber produced from coal, air, water, and petroleum. It was first developed in the 20th century in a laboratory through a reaction between acid and alcohol. In this reaction, two or more molecules combine to form a larger molecule with a repeating structure. In the following text, you will learn more about the properties and applications of polyester.

Properties of Polyester


Polyester fibers can be extremely long, stable, and strong. Compared to traditional fabrics such as cotton, polyester offers several advantages. These fibers do not absorb moisture but can absorb oil, making polyester fabrics suitable for applications that involve contact with water and dirt. Additionally, polyester is used in fire-resistant applications and can be easily dyed.

Polyester fibers are also a good insulator and non-allergenic, making them ideal for filling pillows, duvets, and sleeping bags. Polyester can be categorized into two main types: thermoplastic and thermosetting polymers. Thermoplastic polyesters are further classified into linear aromatic polyester (fibers and polyester films), elastomers (block copolyester), liquid crystal polyester, engineering plastics, aliphatic polyester, and poly(hydroxyalkanoates).
