Polyester garments do not shrink in the dryer. They do, however, produce static and may permanently wrinkle in the dryer due to high heat levels. Therefore, it is best to dry polyester garments in low heat cycles.
Other synthetic materials that do not shrink in the dryer include acetate, spandex, acrylic and nylon. Conveniently, they also resist water-based stains. Consumers can wash garments that contain synthetic materials, including polyester, in warm water with all-purpose laundry detergent. In order to prevent some of the static build-up that occurs frequently with polyester, a consumer can add a fabric softener during the washing cycle.
