Polyester fibres are formed from synthetic polymers, manufactured by the action of polyfunctional acids with polyfunctional alcohols. The fibre forming polymer substance is a long linear polymer with repeating ester groups in its structure. Polyester fiber is also known as Terylene, Terene, Dacron etc. It is a manmade fiber of high polymers which are obtained by esterification of dicarboxylic acids, with glycols or by ester exchange reactions between dicarboxylic acid esters and glycols.
