What are the effects of saltwater spray on polyester fabric integrity?

Saltwater spray can significantly impact the integrity of polyester fabric over time. Exposure to saltwater may lead to fiber weakening, color fading, and reduced tensile strength due to the corrosive nature of salt. Polyester, while generally resistant to moisture, is not entirely immune to degradation when repeatedly exposed to saline environments. Salt crystals can accumulate on the fabric surface, causing abrasion and accelerating wear. Additionally, prolonged exposure may break down the polymer chains, reducing the fabric's elasticity and overall lifespan. To mitigate these effects, rinsing polyester fabrics with fresh water after saltwater exposure and avoiding prolonged sun drying can help maintain durability. Understanding these effects is crucial for industries like marine textiles and outdoor apparel, where polyester is commonly used.
