Polyester is a synthetic fabric made from a polymer called polyethylene terephthalate (PET). It is a strong, durable, and easy-to-care-for material that is resistant to shrinking, stretching, and wrinkling. Polyester is often used to make clothing, upholstery, and other textiles, as well as industrial products such as tires, ropes, and hoses. It is also commonly used in the production of plastic bottles and other containers. Some other common uses for polyester fabric include making curtains, linens, and bedding, as well as bags, backpacks, and other accessories.
