- Researchers developed a method using high-intensity blue LED light to remove natural stains from clothing without harsh chemicals.
- The method effectively removes stains from substances like orange juice, tomato juice, and sweat on fabrics including silk and polyester.
- Blue LED light, combined with ambient oxygen, acts as an oxidizing agent, breaking down stain-causing compounds without damaging fabrics.
- The process avoids the use of traditional bleaching agents like hydrogen peroxide, making it more sustainable.
- Initial tests showed the blue LED light reduced yellow stains more effectively than hydrogen peroxide or UV light, which can damage fabrics.
- Further testing is needed for colorfastness and safety before commercializing the method for home and industrial use.
- The research was conducted by scientists from Asahi Kasei Corporation, a company specializing in fiber products and chemicals.
