FAQ About Differences in Polyester

Polyester is generally more resistant to fading in the sun compared to some natural fibers like cotton or silk. However, it's important to note that prolonged exposure to sunlight can still cause some color fading or degradation in polyester fabrics.

Polyester fibers are inherently more resistant to the damaging effects of ultraviolet (UV) radiation compared to natural fibers. This is because polyester is a synthetic fiber made from petrochemicals, which provide some level of UV resistance. Additionally, polyester fabrics can be treated with UV-protective finishes during the manufacturing process to enhance their resistance to fading.

While polyester is more resistant to fading, it is not completely immune to the effects of sunlight. Over time, exposure to UV radiation can still cause some degree of color fading, especially in brightly colored or dark-colored polyester fabrics. Fading may be more noticeable in areas that receive direct and prolonged exposure to sunlight.
