    Polyester is typically produced through a process known as polymerization. For polyethylene terephthalate (PET), the production process involves the chemical reaction between two primary raw materials: purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and monoethylene glycol (MEG).

  3. Polyester fibre is a “manufactured fibre in which the fibre forming substance is any long chain synthetic polymer composed at least 85% by weight of an ester of a dihydric alcohol (HOROH) and terephthalic acid (p–HOOC–C6 H 4 COOH)”. Figure 4.1 shows the chemical structure of polyethylene terephthalate (PET).

  4. Polyester is synthetic fiber derived from coal, air, waste, and petroleum. Polyester is a fiber from chemical reaction, which occurs between acid and alcohol (Shimao, 2001). Polyesters are polymers that are monomer with bonding of ester linkages.

  5. Polyester fiber is a synthetic fiber that consists of long-chain synthetic polymer with at least 85%, which is widely used in several areas of application in the classical textiles, automotive, and aircraft industries (Bunsell, 2018).

  6. 2 gru 2016 · The wide variety of intermediate and final products made of polyester. As fibers, polyester is a term often defined as “long-chain polymers chemically composed of at least 85 percent by weight of an ester and a dihydric alcohol and a terephthalic acid”.

  7. Polyester is a chemical term which can be broken into poly, meaning many, and ester, a basic organic chemical compound. The principle ingredient used in the manufacture of polyester is ethylene, which is derived from petroleum.
