Sun fade wash is a textile finishing technique that mimics the natural fading process that occurs when denim garments are exposed to sunlight over time. Unlike acid wash, which uses chemicals to create a distressed look, sun fade wash relies on natural sunlight to achieve a similar effect.
The Science Behind Sun Fade
Sunlight contains ultraviolet (UV) rays, which can break down the indigo dye in denim fabric. Over time, prolonged exposure to sunlight can cause the indigo to fade, resulting in a lighter, more worn-in appearance. The rate of fading depends on several factors, including the intensity of the sunlight, the type of denim, and the frequency of exposure.
