How does polyester fabric handle exposure to industrial pollutants in urban outdoor areas?

Polyester fabric is widely used in urban outdoor settings due to its durability and resistance to environmental stressors. When exposed to industrial pollutants, polyester demonstrates remarkable resilience. Its synthetic fibers are less porous than natural fabrics, reducing absorption of harmful chemicals and particulate matter. Additionally, polyester's hydrophobic nature prevents moisture retention, minimizing the risk of pollutant-induced degradation. Studies show that polyester maintains structural integrity longer than cotton or wool in polluted environments, though prolonged exposure may lead to gradual weakening. Regular cleaning can mitigate pollutant buildup, extending the fabric's lifespan. For urban applications, polyester blends with protective coatings offer enhanced pollution resistance.
