1.) Polyester is used for making lightweight sails.

2.)What Polyester is Made of. ... Synthetic polyester is made using a chemical reaction involving coal, petroleum, air and water. This material is made up of purified terephthalic acid (PTS) or its dimethyl ester dimethyl terephthalate (DMT) and monotheluene glycol (MEG).

3.) Rayon, nylon, polyester, acrylic, and spandex are examples of synthetic fibres. Polyamides and polyesters are two groups of synthetic fibres with high strength, not easily stretched and used as textile. Nylon is an example of polyamide polymers. Terylene is an example of polyester polymers.
