What is polyester ?
Polyester is a synthetic polymer made from a type of plastic called polyethylene terephthalate (PET). It is a man-made material that is produced by combining ethylene glycol and terephthalic acid, which are heated and then cooled to form a solid polymer. Polyester is commonly used in a wide range of products, including clothing, upholstery, carpets, packaging materials, and many other household and industrial items. It is known for its durability, wrinkle and shrink resistance, and ease of care. Polyester is also often blended with other fibers to create fabrics with desirable characteristics.
