Uses
Polyester is another synthetic fibre. Actually polyester is the general name of synthetic fibres which contain many ester groups. Polyester (poly+ester) is made up of the repeating units of a chemical called an 'ester' (Esters are the organic chemical substances which give fruits their sweet smell). We can now say that polyester is a synthetic fibre in which the polymer units are linked by ester groups. Terylene is a popular polyester fibre. The chemical compunds (or monomers) used in making polyester fibres are made from petroleum products called petrochemicals. Like nylon, polyester is also a thermoplastic polymer. When molten polyester is forced through the tiny holes of a spinneret, then thin polyester fibres (or polyester threads) are formed. The polyester yarn can be woven to make fabrics.
