Polyester is a class of polymers consisting primarily of polyethylene terephthalate (PET). Polyester is a synthetic polymer that is produced using PTA and MEG. Polyester yarn is the fundamental item in polyester classification. About 40% of the world's manufacturing of polyester is used exclusively for making polyester yarn. Polyester yarn is made by the direct spinning of PTA and MEG. Polyester yarn is obtained by spinning the polymer melt at 265 °C. In polyester yarn, crystalline and amorphous regions are present. They are a thermoplastic material. The chains have a zig-zag structure and are connected to each other by van der Waals connections. The fundamental utilization of Polyester has been in the Textiles field for making Polyester Yarns. Polyester in various structures is utilized broadly as a part of the textile application to make polyester (PET) resin and Filament Yarn, for example, Partially Oriented Yarn (POY), Polyester Drawn Textured Yarn (DTY), Polyester Fully Drawn Yarn (FDY), Polyester Staple Fiber (PSF), Polyester Spun Yarn (PSY), Technical Yarn, Tire cord and Monofilaments Yarn. Polyester yarn is also used as a pressing application such as polyester film, insulation tape, strapping, and some other daily use items. Polyester filament yarn is used as a part of sewing and weaving to make polyester fabrics, for example, customer clothing and household fabrics such as curtains, sheets, bedspreads, and drapers. Thus polyester high tenacity industrial yarn can be used to make ropes, conveyor belts, safety belts, and tire fabrics. Polyester staple fiber is originally used as filling fiber for filling pillows, cushions, sofas, and beds.
