Yes, the sun can lighten clothes.
How the Sun Lightens Clothes
Sunlight contains ultraviolet (UV) rays that can break down the dye molecules in fabrics. This process, known as photodegradation, causes the color to fade over time.
Factors Affecting Lightening
- Fabric Type: Natural fibers like cotton and linen are more susceptible to fading than synthetic fibers like polyester and nylon.
- Dye Type: Some dyes are more resistant to fading than others.
- Exposure Time: The longer the clothes are exposed to sunlight, the more they will fade.
- Intensity of Sunlight: Stronger sunlight, like that found in tropical regions, can cause more rapid fading.
Tips to Prevent Fading
- Wash Clothes Inside Out: This helps protect the dye from direct sunlight.
- Line Dry in the Shade: If possible, dry clothes in the shade to minimize sun exposure.
- Use a Laundry Detergent with Fade Protection: These detergents contain ingredients that help prevent color loss.
- Avoid Overdrying: Overdrying in the sun can accelerate fading.
