How does polyester fabric handle exposure to automotive exhaust fumes?

Polyester fabric is known for its durability and resistance to various environmental factors, including exposure to automotive exhaust fumes. Due to its synthetic composition, polyester is less porous than natural fibers, making it more resistant to absorbing harmful chemicals and pollutants present in exhaust emissions. Studies suggest that polyester can withstand short-term exposure without significant degradation, though prolonged contact may lead to slight discoloration or weakening over time. Its hydrophobic nature also helps repel moisture and oily residues commonly found in exhaust fumes. For applications like car covers or urban clothing, polyester remains a practical choice due to its resilience against pollution-related wear. However, regular cleaning is recommended to maintain its longevity when frequently exposed to harsh automotive emissions.
