Repeated exposure to UV light will cause which change in nylon canopy fabric?

Repeated exposure to UV light will cause which change in nylon canopy fabric?

• A. Weakens fibers, making them brittle and reducing strength.
• B. Stabilizes fibers and increases tensile strength.
• C. Only affects color, not strength.
• D. Improves stretch resistance.

Answer: (A)

Exposure to UV light breaks down nylon’s polymer chains, a process called photo-oxidative degradation. Repeated UV exposure reduces molecular weight, causing the fibers to become brittle and lose tensile strength. That brittleness and weakening directly compromise canopy performance, making it less able to withstand loads or resist tears. Color fading can happen as dyes are affected, but the critical impact on performance is the loss of strength and flexibility. UV doesn’t stabilize nylon or make it stronger, and its effects aren’t limited to color changes.
