Fade-Resistant Fabrics: How UV Protection Works and What to Specify

UV-resistant fabric is solution-dyed at the fiber level. The color pigment is mixed into molten polymer before extrusion, making it part of the fiber. This achieves 500-1000 hours of UV stability versus 100-200 for piece-dyed fabric.

Specify AATCC 16.3 Grade 5 (500+ hours) for spaces with direct sun exposure. BOYA’s solution-dyed line is tested to this standard.
