What is polyester?
According to the classification system used in the United States dictated by the Textiles fiber Product Identification Act (TFPIA), Polyester is categorised as a synthetic fiber. It is commonly referred to as dacron in the USA and as terylene in England. Since polyester is a synthetic fiber, it is largely made of petrochemicals. These chemicals are then converted into reactive units namely monomers and polymers. The monomer of polyester is ethylene glycol and terephthalic acid while the polymer is polyethylene terephthalate.
