Sun, as well as dust and grime, is destructive to fabrics. Light color fabrics generally reflect sunlight and resist fading. Dark colors absorb light and fade. Use lined window treatments, blinds, or shades to protect fabrics from the sun.

Acrylic and polyester stands up to sunlight better than other textile fibers and will retain color over time. Cotton, rayon, and acetate offer slightly less sun resistance. Acetate often is blended with silk or cotton to make it more sun-resistant.

Special Tip: If your windows face west or south, particularly if you live in a warm climate, consider professionally installed window film to diminish the damaging effects of ultraviolet rays.
