Description

polyethylene terephthalate (Polyester) is a category of polymers that contain the ester functional in their main chain. As a specific material, it most commonly refers to a type called (PET). Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics through step-growth polymerization such as polybutyrate.This material is used very widely in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties.
