According to the composition of their main chain, polyesters can be: Increasing the aromatic parts of polyesters increases their glass transition temperature, melting temperature, thermal stability, chemical stability... Polyesters can also be telechelic oligomers like the polycaprolactone diol (PCL) and the polyethylene adipate diol (PEA). The safety belts that are used in automobiles in order to protect the passengers are often made up of polyester along with other components. We are talking about full vertical integration when polyester is produced at one site starting from crude oil or distillation products in the chain oil → benzene → PX → PTA → PET melt → fiber/filament or bottle-grade resin. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Owing to its insulating properties and its relatively soft texture, polyester is used in the production of cushioning materials for pillows.

The general equation for the reaction of a diol with a diacid is : In this classical method, an alcohol and a carboxylic acid react to form a carboxylic ester. Such integrated processes are meanwhile established in more or less interrupted processes at one production site. Polyethylene terephthalate forms the basis for synthetic fibers like Dacron, Terylene and polyester.

[13][14][15], Polyester is a synthetic petroleum-based fibre, and is therefore a non-renewable carbon-intensive resource. Polyesters as thermoplastics may change shape after the application of heat. Polyesters display a wide array of properties and practical applications. In fact, polyester fibres are often used in combination with natural fibres in order to impart certain properties to the clothing.
