How does humidity affect the longevity of polyester fabric in outdoor seating?

Polyester fabric is a popular choice for outdoor seating due to its durability and resistance to fading. However, prolonged exposure to high humidity can impact its longevity. Moisture in the air can weaken polyester fibers over time, leading to reduced tensile strength and increased susceptibility to mold and mildew. Additionally, humidity accelerates UV degradation, causing colors to fade and fabric to become brittle. To mitigate these effects, consider using protective covers, applying UV-resistant coatings, and ensuring proper ventilation. Regular cleaning and storage during extreme weather can also help extend the lifespan of polyester outdoor seating. Understanding these factors allows for better maintenance and prolonged use of polyester fabrics in humid environments.
