Polyester yarn is a type of synthetic yarn made from polyester fibers. Polyester is a synthetic polymer that is made from the chemical reaction between an acid and an alcohol. The resulting fibers are strong and durable, and they are resistant to wrinkling, shrinking, and stretching. Polyester yarn is often used in the production of clothing, upholstery, and other textiles because of its strength and durability. It is also commonly used in the manufacture of tire cord, rope, and other industrial products.
