What is polyester, and how is it made?
Can you tell me what polyester is, and how it's made?
Sure! Polyester is a type of synthetic fabric that is used in many clothing items, such as shirts, pants, and dresses. It is made from petroleum, which is derived from crude oil. The petroleum is then heated and pressurized to create a liquid chemical called ethylene glycol. This chemical is combined with another chemical called terephthalic acid to create the polymer called polyester.
