What is a polyster

Polyester is a synthetic fibre.Polyester (poly+ester)is made up of the repeating unitsof a chemical called an ester.The chemical compounds used in making polyester fibres are made from petroleum products called petrochemicals.

Polymers are substances containing a large number of structural units joined by the same type of linkage. These substances often form into a chain-like structure. Today, the polymer industry has grown to be larger than the aluminum, copper and steel industries combined. Polymers already have a range of applications that far exceeds that of any other class of material available to man. Current applications extend from adhesives, coatings, foams, and packaging materials to textile and industrial fibers, composites, electronic devices, biomedical devices, optical devices, and precursors for many newly developed high-tech ceramics.
