Why is "color fastness" important in fabric covering?

Color fastness is crucial in fabric covering because it directly impacts the longevity and aesthetics of the material used in aircraft. When fabric is subjected to sunlight and UV radiation, any dyes used can degrade over time, leading to color fading. This fading not only affects the visual appeal but can also compromise the fabric's overall integrity and performance. Maintaining the vibrancy of the color ensures that the aircraft retains its intended look and helps in meeting safety and regulatory standards related to visibility and recognition. The ability of the fabric's color to withstand environmental factors, such as sunlight exposure, is therefore essential for ensuring the durability and appearance of the aircraft fabric covering over time.
