The Silent Danger of Dryer Heat: Does Polyester Really Shrink Big Time? When you throw your favorite polyester clothes into the dryer, they promise convenience and quick-drying results—but is there more beneath the surface? A growing concern among fabric care experts is whether polyester truly shrinks significantly when exposed to dryer heat—and if so, how much damage this silent danger can cause to your wardrobe. ### The Hidden Risk of Dryer Heat on Polyester Polyester, a synthetic fabric widely used in athletic wear, casual clothing, and home textiles, is prized for its durability, wrinkle resistance, and fast-drying properties. Unlike natural fibers such as cotton or wool, polyester is not biodegradable and responds differently to heat. Most dryers generate temperatures ranging from 130°F to 160°F (54°C–71°C), strong enough to activate natural shrinkage risks—even if polyester is technically resistant.
