What are the effects of saltwater immersion on polyester fabric integrity?
Polyester fabric is widely used in marine and outdoor applications due to its durability and resistance to environmental factors. However, prolonged exposure to saltwater can impact its structural integrity. Saltwater immersion weakens polyester fibers over time, leading to reduced tensile strength and increased susceptibility to abrasion. The high salinity accelerates chemical degradation, causing discoloration and fiber breakdown. Additionally, salt crystals can embed in the fabric, creating micro-tears during movement. While polyester is more resistant than natural fibers, frequent rinsing and proper maintenance are essential to prolong its lifespan in saltwater environments. Understanding these effects helps in selecting and caring for polyester textiles in marine settings.
