- Polyester is a polymer formed from two different monomers: a ‘dicarboxylic acid’ which contains two carboxylic acid groups, -COOH, and a ‘diol’ which contains two alcohol groups, -OH1. In acidic medium, protonation of terephthalic acid occurs that reacts with ethylene glycol to form an intermediate which rearranges and with the transfer of OH- ions, forms polyethene terephthalate polymer2. Both monomer units are joined together with ester linkage, therefore commonly called polyester2. Polyester can be produced in four basic forms: filament, staple, tow, and fiberfill3.

In the filament form, each individual strand of polyester fiber is continuous in length, producing smooth-surfaced fabrics. In staple form, filaments are cut to short, predetermined lengths. In this form polyester is easier to blend with other fibers.textilelearner.net/polyester-fiber-properties-manufa… Polyesters - Chemistry LibreTexts
