Polyester
Polyester is the general name for any group of widely used synthetic products. Polyesters are strong, tough materials that are manufactured in a variety of colours, shapes and sizes.
The first commercial production of polyester was by the du Pont de Nemours Company. It is the most used fiber in the United States.
P
olyesters
are made from chemical substances found mainly in petroleum.
Polyesters are manufactured in three basic forms - fibers,
films
and plastics.
Polyester fibers are used to make fabrics. Poly (ethylene terephthalate, or simply PET) is the most common polyester used for fiber purposes. This is the polymer used for making soft drink bottles. Recycling PET by re-melting it and extruding it as fiber saves much raw materials as well as energy.
PET is made by ethylene glycol with either terephthalic acid or its methyl ester in the presence of an antimony catalyst. In order to achieve high molecular weights needed to form useful fibers, the reaction has to be carried out at high temperature and in a vacuum. Polyester is used to make most forms of clothing like shirts, running shorts, track pants, windbreakers, and lingerie. It can also be made into curtains and draperies.
