Which of the following factors does NOT affect fabric durability?

Fabric color does not affect the inherent durability of the fabric itself. While it may influence other characteristics, such as heat absorption or aesthetic perception, the actual material composition and structure—regardless of color—play the primary roles in determining how well the fabric withstands wear and environmental factors. Other options, like sun exposure, water damage, and pollution, can significantly impact the degradation of the fabric over time, affecting its strength, flexibility, and overall longevity. Therefore, while fabric color can have implications for appearance and performance under specific conditions, it does not fundamentally alter the durability of the fabric.
