Can polyester fabric be treated to resist staining from pollution or smog?

Polyester fabric, widely used for its durability and affordability, can indeed be treated to resist staining from pollution or smog. Specialized fabric treatments, such as nanotechnology coatings or chemical finishes, create a protective barrier that repels pollutants and prevents deep staining. These treatments often involve water- or oil-repellent solutions that block particulate matter from adhering to the fabric fibers. Additionally, some manufacturers incorporate anti-static properties to further reduce pollutant attraction. While treated polyester may require periodic reapplication of protective coatings, it offers a practical solution for urban environments or high-pollution areas, helping garments and textiles maintain a cleaner appearance for longer. Regular care, such as gentle washing and avoiding harsh detergents, can also prolong the fabric's stain-resistant properties.
